210 Mr. S. Stillman Berry on a new 



of one species, so that the known forms of " gemsbok " must 

 stand as follows : — 



Oryx gazella gazella (Linn.). S. Africa. 



. b/ainei, Rothsch. Angola. 



beisa (Riipp.). Abyssinia. 



gallarum (Neuni.). S. Gallaland. 



annectens, HoU. Brif. E. Africa. 



suhcaUotis, Rothsch. S. Brit. E. Africa. 



callods, Thorn. Tanganyika Prov. 



In addition to these^ I consider the Arabian Oryx only an 

 extreme form of the same species, and it should stand as : — 



Oryx gazella leucoryx (Pall.). Arabia. 



XX. — A neio Neotreme BracMopod from Cnlifornia.

Among other unusual zoological material discovered by 

 Mr. W. H. Golischjof the South-west Museum, Los Angeles, 

 in his investigation of corals and spong<s hauled in by 

 fishermen from deep water off the coast of Southern Cali- 

 fornia, is a single specimen of a brachiopod, which seems to 

 be not oidy new to science^ but representative of a genus and 

 family hitherto unreported from the west coast of North 

 America. 



For his kindness in immediately placing this interesting 

 specimen at my disposal, I beg to tender AJr. Golisch appro- 

 priate acknowledgment, while I am further indebted to 

 Messrs. Y. Hirase and J. T. Kuroda, of Kyoto, Japan, for 

 the loan for comparative purposes of two young specimens 

 of Cra/im (C?'a/i/5Cws)j/'aj>omcti, A. Adams, from the Hirase 

 Collection.
