Some Recent Additions to the Fauna of California. 



. BY J. G. COOPER, M. D. 



In Yol. II, p. 118, of our Proceedings, there is published a list of animals 

 discovered by me while stationed as surgeon at Fort Mojave, Colorado valley, 

 three of them undescribed before, and twenty others new to this State. I may 

 here remark that all the species there mentioned were actually collected by me 

 and preserved for the State Museum, except two included in brackets, [ ] 

 which I have since obtained also. Yet some authors have referred to them as 

 only "observed" by me, and even ignored entirely my notice of some of them 

 while referring to others mentioned in the same article. One or two names 

 will need correction in the present pajier. 



I now present the additions iwhich I have been able to make to our lists of 

 the two highest classes since then. Those collected by aid of the Geological 

 Survey are distinguished by a *, new species by a f. Some were obtained 

 during my service in the army, or by friends whose names are duly mentioned. 



The chief authorities for the previous discovery of species in this State are 

 the volumes on mammals and birds of North America by Baird, Cassin and 

 Lawrence, of which the text forms the 8th and* 9th volumes of the Pacific R. 

 R. Reports, besides a few collected here by Gambel, Heermann and others, not 

 mentioned therein. Many are mentioned by authors as having been seen in 

 this State, but have not been confirmed by collections. 



Full information on all our species has been prepared for the Reports of the 

 Geological Survey, now nearly ready for publication, and to be profusely illus- 

 trated. 



Besides those here mentioned, there have been added to our fauna since 1859 

 the following numbers of species in the lower classes of vertebrates : 



Reptiles and Batrachians. — Ten or twelve species, of which three or four 

 are probably new, mostly obtained through the Geological Survey. 



Fishes. — About fifty species, collected by myself while in the Survey, or by 

 Dr. Ayres, Mr. Hubbard, aud other members of our Academy, who obtained 

 them chiefly in the San Francisco market. Many of these were described in 

 these proceedings. 



Having recently furnished a complete enumeration of the vertebrata of this 

 State for Mr. Cronise's "Natural Wealth of California," I find the number of 

 species known to me to be as follows. In order to show the progress of our 

 knowledge on this subject, I add the number of each class believed to inhabit 

 California in 18'62, when I made the estimate published by Prof. Whitney in 

 his Annual Report, and in our Proceedings, Yol. Ill, p. 23, with other statis- 

 tical items —
