A new species of parasitic copepod occurring in western North America is described, Ergasilus nerkae n. sp. An emendation of E. turgidus Fraser, 1920 and a redescription of E. auritus Markevich, 1940 are presented. A total of four species resembling E. caeruleus (E. turgidus, E. confusus Bere, 1931, E. auritus, and E. nerkae) have so far been described, and characters to distinguish the species of this group are given.

Allosaurus is one of the best known theropod dinosaurs from the Jurassic and a crucial taxon in phylogenetic analyses. On the basis of an in-depth, firsthand study of the bulk of Allosaurus specimens housed in North American institutions, we describe here a new theropod dinosaur from the Upper Jurassic Morrison Formation of Western North America, Allosaurus jimmadseni sp. nov., based upon a remarkably complete articulated skeleton and skull and a second specimen with an articulated skull and associated skeleton. The present study also assigns several other specimens to this new species, Allosaurus jimmadseni, which is characterized by a number of autapomorphies present on the dermal skull roof and additional characters present in the postcrania. In particular, whereas the ventral margin of the jugal of Allosaurus fragilis has pronounced sigmoidal convexity, the ventral margin is virtually straight in Allosaurus jimmadseni. The paired nasals of Allosaurus jimmadseni possess bilateral, blade-like crests along the lateral margin, forming a pronounced nasolacrimal crest that is absent in Allosaurus fragilis.

The millipede genus Amplaria Chamberlin, 1941 (senior synonym of Vaferaria Causey, 1958 and Speostriaria Causey, 1960) is endemic to western North America, from Mt. Palomar and San Luis Obispo, California, north to southwestern British Columbia, Canada, and east to northern Idaho. Seven species names are currently assigned to the genus. Below I describe ten additional new species: Amplaria crawfordi, Amplaria fontinalis, Amplaria rykkenae, Amplaria arcata, Amplaria baughi, Amplaria staceyi, Amplaria umatilla, Amplaria cervus, Amplaria mendocino and Amplaria flucticulus, and provide new records of Amplaria nazinta Chamberlin.

A new species Bradyidius saanichi from Saanich Inlet, Vancouver Island, British Columbia, Canada, is described and illustrated in detail. This species is closely related to B. pacificus (Brodsky, 1950) among the six previously known species in the genus, but can be readily distinguished from the latter by the strongly divergent rostral rami in addition to some other differences.

AbstractHybomitra enigmatica n. sp., previously confused with Hybomitra sonomensis (O.S.), is described in larval, pupal, and adult stages and compared with the latter species and with H. phaenops (O.S.). Hybomitra philipi Stone is synonymized with H. sonomensis. The distribution of these species in western North America is given.

A single carapace and its counterpart of an erymoid lobster collected from the Middle Jurassic Smithers Formation in British Columbia, permits description of a new species, Eryma walkerae. The specimen represents only the fourth species of Eryma described from North America and documents a north polar route of dispersal for erymids into North America.
