Cocks and Rong (1989) subdivided the species of the Ordovician brachiopod genus Bimuria into two groups, those with a simple, or not undercut, cardinal process and those with an undercut cardinal process. They placed the second group in a new genus, Cooperea, and grouped Cooperea with Craspedelia in the new subfamily Craspedeliinae of the family Sowerbyellidae. However, the cardinal process of Bimuria ranges from not undercut to undercut within at least two species. Cooperea is therefore placed in synonymy with Bimuria, and Craspedelia is returned to the Bimuriidae.Cocks and Rong (1989) inferred that, with rare exceptions, the cardinal process of the Plectambonitacea evolved from simple to trifid to undercut. The evidence from Bimuria indicates, however, that the undercut process developed more than once and, in Bimuria, directly from the simple type.As an adjunct to the above discussion three new species are described: Bimuria gilbertella, Craspedelia intonsa, and Craspedelia sp. 1. Craspedelia is a rarely reported genus documented here for the first time in western North America (northern California). Additional evidence is introduced that the ratio Lmusbv/Lebv decreased from middle to late Ordovician species of Bimuria.

Three New Species

Twenty three enteropneust species have been described from the west coast of North America, including one species from the family Ptychoderidae, Glossobalanus berkeleyi from the Salish Sea, Vancouver Island. Here we use morphology to describe three additional species of acorn worms in the genus Glossobalanus: G. williami from Cape Arago, Oregon; G. hartmanae and G. barnharti fromLa Jolla,California. Notes on the habit and localization of each species as well as a dichotomous key to the genera of the family Ptychoderidae are provided.

A New Species

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 new species, Stenozonium leonardi, the northernmost representative of the Polyzoniidae in western North America and the only one north of the Columbia River, is described from the Olympic Peninsula of Washington; it is isolated by some 180 mi (288 km) from S. benedictae Shelley, 1998, in coastal Oregon. Stenozonium alone among the four polyzoniidan genera in western North America consists of entirely allopatric and widely separated species, with one apiece in California, Oregon, and Washington-evidence that it diversified earlier than its ordinal counterparts.
