ACADEMY OF NATURAL SCIENCES. 69 



Regular Meeting, October 19th, 1863. 

 President in the Chair. 



Six members present. 



Dr. Ferdinand Mueller was elected an Honorary member. 

 Frederick Wideman, of Sinaloa, Alex. Drauphing of San Sebastian, 

 and S. W. Morrell, of Mazatlan, were elected Corresponding mem- 

 bers. 



Dr. Cooper exhibited specimens of Lagomys princeps, the " Little 

 Chief Hare," from the summits of the Sierra Nevada. He remarked 

 that this rare animal lived about the limits of perpetual snow, and 

 was so rarely seen that residents for several years near its resorts 

 had never seen it. He found it quite common in a very limited 

 district, though difficult to obtain, from its extreme shyness. Though 

 before found in the Rocky Mountains near South Pass, and Salt 

 Lake, where it is called " Coney," this was the first record of its 

 occurrence so far to the west and south.
