LEPUS AUDUBONII, Baird.— Audubon's Hare. 

 Plate VIII. 



Baird, Gen. Rep. Mammals, 1857, 608. 



Sp. Ch.— Size a little less than that of L. sylvaticus; ears longer than the head; hind feet rather short, but longer than the 

 ears, fully furred beneath. Tail rather long. 



Above, mixed yellowish brown and black, paler on the sides and throat ; beneath, pure white. Thighs and rump grayish. 

 Back of neck rusty; fore legs somewhat similar. Hairs lead color at the base, on the middle of the back (over the loins) 

 passing directly through dark brown to black, then yellowish brown ; on the sides, rump, and fore part of back, the passage into 

 the first brown or black ring is through grayish, yellowish, or reddish brown. 



This species we found somewhat abundant in the markets of San Francisco. 



LEPUS TROWBEIDGII, Baird. 

 Plate XIV. 



Lepus troicbridgii, Baird, Pr. A. N. Sc. Phila. VII, April, 1855, 333. — Ib. Gen. Rep. Mammals, 1857, 610. 

 Sp. Ch. — Size small, less than that of L. auduboni. Head small. Ears about equal to it in length. Tail very short, almost 

 rudimentary ; hind feet very short, well furred, considerably shorter than the head. Color above, yellowish brown and dark 

 brown ; beneath, plumbeous gray. Sides not conspicuously different from the back, but paler. Back of neck pale rusty. 

 Ears grayish and black on the external band ; ashy gray elsewhere, with little indication of darker margin or tip. 



This species was found associated with the preceding in the San Francisco market. Both 

 appear to be quite common near the coast, as far south as San Diego.
