The tube-dwelling cross-lineate Navicula species on the west coast are dominated by a taxon that belongs in or near the N. ramosissima – N. mollis complex. Morphometric data were used to establish that a single, variable population exists. The species was assigned to N. rusticensis. Cells are 28 ± 7 × 5 ± 1 μm and striae number 14 ± 2 in 10 μm; these cells differ from the ramosissima–mollis complex in having 1–3 short central striae that form a narrow rectangular area. The range of size encompasses published limits for both N. ramosissima and N. mollis. A key to tube-dwelling diatoms of the west coast completes this two-part checklist. Key words: diatoms, Pacific, tube-dwelling, Navicula rusticensis, Navicula ramosissima.

A New Species

Peniculus asinus, a new species of copepod parasitic on Sebastes (Pisces: Teleostei) off the Pacific coast of Canada is described and illustrated. The copepod is an unique member of its genus in that it possesses cephalothoracic holdfast processes. The discovery of a Peniculus with these processes is taken as evidence confirming the place of this genus in the family Pennellidae.

Phoronopsis Harmeri

Six phoronids from the west coast of North America, Phoronis vancouverensis, Phoronis pallida, Phoronis psammophila, Phoronis ovalis, Phoronopsis harmeri, and one that is possibly Phoronis architecta, are described. Phoronopsis harmeri is considered to be synonymous with Phoronopsis viridis. Taxonomic relationships within the Phoronidea are discussed. It is suggested that the phylum may most naturally be divided into four categories of wide geographic range. The characteristics of each of these categories are discussed.

A New Species

Abstract— A new species of Galianthe from the west coast of Colombia and Ecuador that has fruits with indehiscent mericarps is described and illustrated. Galianthe holmneielsenii is most similar to Borreria ocymifolia and G. spicata, but differs in floral, fruit, and seed traits. An illustration of the diagnostic characters, a distribution map, information about the conservation status of the new species, and a key to the Galianthe species in Colombia and Ecuador are provided.

Two species of terebratulide brachiopods are described from the upper part of the Bateque Formation (middle Eocene) on the Pacific coast of Baja California Sur, Mexico, Terebratulina cf. Terebratulina louisianae Stenzel, 1940, and Terebratalia batequia n. sp. Terebratalia batequia n. sp. is the earliest confirmed record of the genus Terebratalia Beecher, 1893, which has been an important component of Pacific brachiopod faunas through to the present day. The occurrence of Terebratulina cf. Terebratulina louisianae Stenzel is one of the earliest records of the genus from the west coast of North America. These brachiopods, like other elements of the Bateque invertebrate fauna, may record Eocene migration from the Atlantic to Pacific Ocean via the Central American seaway.

I present the systematics and distribution of five new species of oribatid mites in the genus Ceratoppia (Oribatida: Peloppiidae) from western North America. The species are described on the basis of adult morphology using the following character states: number of hypostomal setae, number, length and expression of posterior notogastral setae, length of lamellae and lamellar cusp, length of interlamellar setae, and the shape and dentition of the rostrum. Ceratoppia indentata n. sp. is described from forest floor habitats, while Ceratoppia longicuspis n. sp. and Ceratoppia tofinoensis n. sp. are described from arboreal bryosphere habitats; Ceratoppia offarostrata n. sp. is associated with bark habitats. Ceratoppia valerieae n. sp. was collected from both arboreal and forest floor samples. Distributions of all species are provided based on museum and collection records; C. indentata, C. longicuspis, C. tofinoensis are recorded from coastal temperate coniferous rainforests of the Pacific Northwest of North America, while C. valerieae was found in coastal temperate rainforests and extending along the southern border of British Columbia into eastern Alberta. Ceratoppia offarostrata is collected only from a small number of locations on the west coast of Canada. Comments on other North American Ceratoppia species is given. A morphological key is presented to the described adult species for the genus Ceratoppia in North America.

The Rich

The west coast of North America encompasses some of the richest and most diverse maritime environments on earth. Even in their presentday impoverished state, they support major commercial fisheries, large whale migrations and dense sea mammal populations. From the earliest days of European exploration, visitors such as the redoubtable Captain James Cook commented on the rich culture of Pacific coast peoples (Beaglehole 1967). ‘Their life may be said to comprise a constant meal,’ remarked Spanish friar Pedro Fages of the Chumash peoples of the Santa Barbara Channel in southern California. At European contact, between the 16th and 18th centuries AD, the shores of the Bering Strait, the Pacific Northwest and parts of the California coast supported elaborate, sophisticated and sedentary huntergatherer peoples. These decimated and muchchanged societies still enjoyed elaborate ceremonials and intricate social relations as late as the late 19th and early 20th centuries, when pioneer anthropologists such as Franz Boas and John Harrington worked among them. From these researches have come classic stereotypes of west coast peoples as ‘complex huntergatherer societies’, some of which were organized in powerful chiefdoms. Peoples like the Tlingit, the Kwakiutl and the Chumash have become the epitome of complex huntergatherers in many archaeologists’ eyes.
