Urochordeumatidae Silvestri, 1909 includes a single species, Urochordeuma bumpusi Silvestri, 1909, with U. porona Chamberlin, 1941 as a new junior subjective synonym. The family Urochordeumatidae is removed from the superfamily Caseyoidea and transferred to the superfamily Striarioidea. The species is known only from four counties in Washington State in the North Cascades: Pierce, King, Thurston and Whatcom. The occurrence of U. bumpusi from Whatcom County is a significant range extension.

In Australia the frog family Microhylidae is largely restricted to tropical rainforests of the Wet Tropics region in the north-east of the country, but in that region the family is diverse. Only one species, Cophixalus ornatus, is widespread in the WetTropics but there has been suspicion that it may comprise multiple species. A recent study (Hoskin et al. 2011) assessedgenetic and phenotypic variation across the range of C. ornatus, finding three deeply divergent genetic lineages that differin mating call and some aspects of morphology. Two of these lineages abutt in the central Wet Tropics and in that areahybridization was found to be very limited despite sympatry at high densities. Based on multiple lines of data, Hoskin etal. (2011) concluded that the three genetic lineages represent biological species. The taxonomy of these three lineages isresolved here. I describe two new species, Cophixalus australis sp. nov. and Cophixalus hinchinbrookensis sp. nov., andredescribe C. ornatus. The three species are not distinguishable based on any single morphological or call trait and arebest identified by genetics or locality. The distributions of the three species are largely allopatric. Cophixalus ornatus isfound in rainforest in the northern Wet Tropics, C. australis sp. nov. occurs in rainforest and adjacent wet sclerophyllforests in the central and southern Wet Tropics, and C. hinchinbrookensis sp. nov. inhabits rainforest and montane heathon Hinchinbrook Island. All three species are common. Cophixalus australis sp. nov. contains three genetic subgroupsthat are considered a single species based on phenotypic similarity and high levels of hybridization at contact zones. Thedescription of Cophixalus australis sp. nov. and Cophixalus hinchinbrookensis sp. nov. brings the number of Australian Cophixalus species to 18, 15 of which are restricted to the Wet Tropics region.

This report provides a checklist of the echiurans from the Atlantic Ocean and maps their distribution. Investigations on the taxonomy of this group since the publication of the monograph by Stephen and Edmonds (1972) on the phyla Sipuncula and Echiura have yielded two new genera, 12 new species and 13 new records. Currently the echiuran fauna of the Atlantic comprises three families, 25 genera and 63 species. The family Bonelliidae contains 35 species in 18 genera; the Echiuridae is represented by six genera and 27 species, and the Urechidae by a single species Urechis chilensis (Müller). This study shows that the Atlantic has a relatively high species diversity, comprising about 38% of the known world fauna. Bonelliids alone comprise about 56% of the echiuran fauna of the Atlantic. An analysis of distribution is given in relation to general biogeographic regions and faunistic provinces. Dichotomous keys for the identification of genera and species of echiurans from the Atlantic is provided. The North Temperate component is the richest and most diverse, making up about 68% of the Atlantic echiuran fauna; 25 species have been recorded from within the tropics; and the South Temperate component is poorly represented, with only about 19% of the total fauna. The cosmopolitan component is also poorly represented, with only four species, so far, known. Thirteen species of echiurans are provisionally considered to be endemic to the Atlantic. Members of the Echiuridae are usually shallow-water inhabitants of intertidal and subtidal zones while bonelliids exhibit a higher species richness on deeper bottoms of all oceans, mostly at depths of 1000–6000 m in the Atlantic.

Abstract The spatial distribution and seasonal movement patterns of isolated populations of mountain goats (Oreamnos americanus) in the North Cascade range of Washington State is not fully understood. Determining harvest potential in these populations is challenging without a clear understanding of spatiotemporal movement, space use, and spatial overlap. Mountain goat populations in the North Cascades are fragmented and many have declined considerably from historic estimates. Identification of harvestable populations requires a clear understanding of population size, distribution, and movement. We investigated the population trends and spatial distribution of mountain goats in the Boulder River North Harvest Area in the Boulder River Wilderness of Washington State. We reviewed recent mountain goat population estimates and used Global Positioning System collar data to determine year-round and seasonal home range distributions, spatial overlap within these ranges, and proximity of mountain goats to roads and trails. We found 2 populations of mountain goats inhabiting the Whitehorse and Three Fingers Mountains in the Boulder River North Harvest Area. These 2 populations were spatially distinct and did not intermix during our study period. We also found mountain goats using exclusive areas seasonally on Whitehorse Peak. The Whitehorse population appeared to be more vulnerable to harvest than Three Fingers based on its proximity to roads and trails. This study provides space use and movement information on mountain goats in the North Cascades Range that can be used to improve harvest management of fragmented and isolated populations. Our results indicate that a re-evaluation of harvest level, harvest unit boundary, and monitoring strategy may be warranted for the Boulder River North mountain goat harvest area.

AbstractThe holotype partial skull ofAgorophius pygmaeus(the monotypic form for both the genusAgorophiusand the Family Agorophiidae) has been missing for approximately 140 years. Since the discovery ofAgorophius pygmaeus, many additional taxa and specimens have been placed in the Family Agorophiidae, only to be reclassified and removed later. This has created confusion as to what is and what is not an agorophiid and a lack of clarity as to what characteristics delimit the Agorophiidae. A newly discovered skull of an agorophiid recently collected from an underwater cliff face of the Ashley River, South Carolina, USA, is assigned toAgorophius pygmaeus. It derives from the base of the Ashley Formation (early Oligocene). The new specimen consists of most of the skull and periotics, which are well preserved and described for the first time in an agorophiid. The new specimen provides an opportunity to diagnose the Agorophiidae and place the genus and species within the phylogenetic context of the early odontocete radiation in the Oligocene, along with other taxa such as the Ashleycetidae, Mirocetidae, Patriocetidae, Simocetidae, Waipatiidae, and Xenorophidae. Based on this new understanding, Agorophiidae are known with certainty only from the early Oligocene of South Carolina, with other undescribed, potential agorophiid specimens from the Oligocene of the North Pacific region (Japan, Mexico, and Washington State).

Chowder Ridge, a high elevation area near Mt. Baker, Washington State, possesses a moss flora of 77 species based on collections made during two visits. Three species, Dicranum muehlenbeckii B.S.G., Rhacomitrium microcarpon (Hedw.) Brid., and Mnium arizonicum Amann, are reported new to Washington State. Coscinodon calyptratus (Hook.) C Jens. and Grimmia ovalis (Hedw.) Lindb. are noted for the first time from the west slope of the North Cascades. Chowder Ridge harbors an unusually large number of disjunts of the Rocky Mountain interior compared with typical sites on the west slope of the North Cascades, while the Pacific North American element is underrepresented. The bulk of the flora consists of species widespread in western North America.

Abstract Background: The spatial distribution and seasonal movement patterns of isolated populations of mountain goats (Oreamnos americanus) in the North Cascade range of Washington State is not fully understood. Determining harvest potential in these populations is challenging without a clear understanding of spatiotemporal movement, space use, and spatial overlap. Mountain goat populations in the North Cascades are fragmented and many have declined considerably from historic estimates. Identification of harvestable populations requires a clear understanding of population size, distribution, and movement. We investigated the population trends and spatial distribution of mountain goats in the Boulder River North Harvest Area in Boulder River Wilderness of Washington State. Methods: We reviewed recent mountain goat population estimates and used Global Positioning System collar data to determine year-round and seasonal home range distributions, spatial overlap within these ranges, and proximity of mountain goats to roads and trails.Results: We found 2 populations of mountain goats inhabiting the Whitehorse and Three Fingers Mountains in the Boulder River North Harvest Area. These 2 populations were spatially distinct and did not intermix during our study period. We also found mountain goats using exclusive areas seasonally on Whitehorse Peak that may represent separate or isolated groups. The Whitehorse population appeared to be more vulnerable to harvest than Three Fingers based on its proximity to roads and trails. Conclusions and Management Recommendations: This study provides space use and movement information on mountain goats in the North Cascades Range that can be used to improve harvest management of fragmented and isolated populations. Our results indicate that a re-evaluation of harvest level, harvest unit boundary, and monitoring strategy may be warranted for the Boulder River North mountain goat harvest area.
