800 [February, The Committee on the following paper by Prof. Baird and Mr. Girard reported in favor of publication in the Proceedings. 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. 2. Eutainia ordinoides, B. and G. Proc. Acad. Nat. Sc, Phila., vi., 1852, 176, and Cat.

From Vallecitas, Cal. * 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.
