List of Reptiles collected hi California by Dr. JohnL. Le ContCj with description 



of new Species. 



By S. F. Baird and Charles Girard. 



The following species of reptiles were collected by Dr. Le Conte, during a 

 scientific exploration of California made in 1850-51. As in his previous travels 

 through various parts of North America, Dr. Le Conte, in addition to the Co- 

 leoptera which attracted his especial attention, collected in other departments of 

 Natural History, making additions of greater or less extent in all. 



The present enumeration, although containing all the species brought home 

 by Dr. Le Conte, gives no idea of the numbers actually collected. Owing to 

 the breaking of several jars and the difficulty of transportation, many valuable 

 species were lost, especially from the Colorado and from San Diego. 



The Batrachians from San Francisco were collected in February, 1850 ; the 

 specimens from San Jose in April, and those from San Diego in May to Septem- 

 ber of the same year. Bufo halophila was found at Benicia in August, and 

 Rena humilis at Vallecitas in October. The Colorado specimens were mostly 

 collected in November, 1850, and October, 1851.* 



OPHIDIANS. 



1. Crotalus LUCIFER?? B. and G. Proc. Acad. Nat. Sc, Phila., xi. 1852. 

 Hab. San Diego, Cal. Owing to the imperfect condition of the specimen, 



(a dried skin,) it has been impossible to state to what species this belongs. We 

 have, however, provisionally referred it to the above, as the one to which it 

 bears the closest resemblance.

* It is proper to remark, that besides the strong friendship manifested towards 

 me and towards the objects of my journey, by all the officers stationed at the 

 military posts w^hich I visited, especial facilities were affi^rded by Major W. H. 

 Emory, then in charge of the American Boundary Commission, whose valuable 

 explorations in those desert regions have already contributed so much to science, 

 and whose labors, I am happy to say, are still further illustrated by the collec- 

 tions made by me. J. L. Lee.
