CALIFORNIA CRUSTACEA OF THE ORDER CUMACEA 



By Carl Zimmer 



Zoological Museum, XJniverslty of Berlin, Berlin, Germany 



The collection of cumaceans here reported upon was obtained in 

 the vicinity of Newport, Calif., by Prof. G. E. MacGinitie, director 

 of the Kerckhoff Marine Laboratory of the California Institute 

 of Technology at Corona Del Mar, Calif. Newport lies in Orange 

 County at about latitude 33°38' N. 



Knowledo-e of the cumacean fauna of the Pacific coast of North 

 America is so slight that every new collection from that region 

 contributes important information. Until now only three species 

 have been known from the coast of California: Bathycuma (?) 

 longicaudata Caiman, from San Diego, Calif. ; Diastylopsis dawsoni 

 S. I. Smith, ranging from Monterey Bay, Calif., to Chignik Bay, 

 Alaska; and Colurostylis (?) occidentalis Caiman, from Monterey 

 Bay, Calif., to Oregon. Only the last of these is represented in the 

 present collection, while each of the other seven species represented 

 proves to be new. 



The genus Gyclaspis was hitherto unknown from the North 

 American-Pacific region, and the genera ProcampyJaspis and 

 Oxyurostylis were unknown from the entire Pacific region. Of the 

 latter, only the typical species, O. smithi Caiman, which is found 

 only on the Atlantic-American coasts from Louisiana to Casco Bay, 

 Maine, was known.
