Two new Pertusaria species with brown ascospores are described from southern California and Baja California, Mexico. Pertusaria islandica sp. nov. is characterized by pertusariate to pseudolecanorate ascomata, ellipsoid ascospores, 8-spored asci, a strongly K+ violet reacting epithecium, and the presence of the 2′-O-methylperlatolic acid chemosyndrome, while P. occidentalis sp. nov. has pertusariate ascomata, globose to subglobose ascospores, 8-spored asci, and contains the arthothelin chemosyndrome. Pertusaria ochracea Kremp. is reduced to synonymy with P. melanospora Nyl.

AbstractIn western North America, the milliped order Callipodida is represented by the Colactidini, Tynommatini stat. n., and Diactidini tribus n., in the subfamily Tynommatinae, family Schizopetalidae; a coordinate tribe, the Texophonini, occurs on the Gulf Coast of south Texas. The Tynommatini consists of two genera and four species: Tynomma mutans (Chamberlin), T. magnum Buckett & Gardner, and T. gardneri sp. n., occurring around Monterey and San Pablo/San Francisco Bays, California, and Idrionaria dineh gen. n. & sp. n., in Washington County, Utah. The Colactidini ranges from Durango, Mexico, to central Utah and California east of the Sierra Nevada, with disjunct areas in southern California and Baja California, the latter extending northward to metropolitan San Diego. It is represented by two genera and 6 species: Colactis Loomis: C. tiburona (Chamberlin), utorum (Chamberlin), and protenta and quadrata, both by Loomis; and Heptium Loomis: H. carinellum and scamillatum, both by Loomis. The Diactidini, occupying coastal southern California and the adjacent fringe of Baja California, is comprised of three genera and 10 species: Diactis Loomis: D. soleata, triangula, and frondifera, all by Loomis, and amniscela, cupola, jacinto, procera, and strumella, all spp. n.; Florea sinuata gen. n. & sp. n.; and Caliactis bistolata gen. n. & sp. n. The following new synonymies are proposed: C. yuma Chamberlin, sideralis Loomis, and loomisi Hoffman under C. tiburona; C. briggsi Shear and saxetana and baboquivari, both by Loomis, under C. utorum; H. canum Chamberlin under H. carinellum; and Etiron paroicum and pearcei, both by Chamberlin, under D. triangula and T. mutans, respectively. The eastern Nearctic callipodid fauna is summarized and significant new localities are reported; Tetracion antraeum Hoffman, stat. n., is elevated from a subspecies of T. jonesi Hoffman.

The cassiduloid echinoid Calilampas californiensis n. gen. and sp. is described from middle lower Eocene (“Capay Stage”) shallow-marine sandstones in both the middle part of the Bateque Formation, Baja California Sur, Mexico, and the lower part of the Llajas Formation, southern California. The new genus is tentatively placed in family Pliolampadidae. The cassiduloid Cassidulus ellipticus Kew, 1920, previously known only from the “Capay Stage” in California, is also present in “Capay Stage” shallow-marine sandstones of the Bateque Formation.

Generic Distribution

The family Macrosternodesmidae is redefined and recorded from western North America. Four small-bodied species in Arizona and California, USA, and Baja California Norté, Mexico, are assigned to Tidesmus Chamberlin 1943; Phreatodesmus and Oodedesmus, both authored by Loomis, 1960, are placed in synonymy. Phreatodesmus torreyanus Loomis, 1960 and O. variabilis Loomis, 1960, are transferred into Tidesmus as valid species; P. cooki Loomis, 1960, is a synonym of T. episcopus Chamberlin, 1943, the type species, and P. dentatus Loomis, 1960, is a synonym of P. torreyanus. Brachydesmus hastingsus Chamberlin, 1941, also is referable to Tidesmus; a topotypical male is needed to establish its identity in the absence of authentic type specimens. Tidesmus hubbsi Chamberlin, 1943, based on unidentifiable females, is geographically segregated and incompatible with the otherwise coherent generic distribution. A topotypical male is also necessary to determine its identity; for now, we remove hubbsi from Tidesmus and leave it unassigned.

Pacific Slope

Four new venerid species from the Cretaceous of the North American Pacific Slope are described and four previously described species are reassigned. Of the new species, two are allotted to new genera: Rhaiphiale based upon Rhaiphiale pharota n. sp. and Egrona based upon Egrona fallax n. sp., both Turonian in age and from southern California. The other new species are Loxo quintense n. sp., of late Maastrichtian age from California, and Paraesa cedrina n. sp., late Albian in age from Baja California, Mexico. The previously described species “Meretrix” arata Gabb, 1864, Turonian, and “?Meretrix” fragilis Gabb, 1869, late Maastrichtian, are placed in the new genus Callistalox; “Meretrix” lens (Gabb, 1864), Campanian age, and Flaventia zeta Popenoe, 1937, Turonian, are provisionally assigned to Paraesa Casey, 1952. This is the first identification of Paraesa from the Pacific Slope of North America. No species of Flaventia Jukes-Brown, 1908, is now known in Pacific Slope faunas.

Cuvier’S Beaked Whale

Previously known and new strandings of Ziphius cavirostris are tabulated for the coast of western North America and found to range between Alaska and the tip of Baja California. Strandings are most numerous between February and September, and whales less than about 18 ft long have not usually stranded north of 42 °N. Adults and juveniles strand singly, not in mass, but there is evidence for recurrent, single strandings near the same spot at different times.
