LEPORIDA—LEPUS BRASILIENSIS VAR. GABBI. 349 
Rica (one of them quite immature) are much more yellow above than the 
Parana specimen, the general color above being yellowish-rufous mixed 
with black. The ears are also fully one-fourth shorter than in the Parana 
specimen, and considerably shorter than the measurements given by Water- 
house. The differences are so striking that at first I was inclined to regard 
the Costa Rican specimens as specifically distinct from the South American 
L. brasiliensis, and I propose finally to treat them as varietally distinct, under 
the subspecific designation of gabbi, which may be characterized as follows ; 
LEPUS BRASILIENSIS var. GABBI. 
Central American Hare. 
Size of Lepus trowbridgei ; ears very short; tail rudimentary. Above 
pale cinnamon-brown, strongly varied with blackish. Whole upper surface 
of the head bright yellowish-ferruginous mixed with black. Nape pale 
rufous. A conspicuous, large, whitish spot below and behind the nostril, 
bordered by yellowish-brown, which latter color extends over the sides of 
the head, where it is varied with black. Chin and space over the rami of 
the lower jaw white. Fore neck pale yellowish-brown; rest of lower parts 
white. Ears anteriorly varied with pale rufous and black, with a narrow 
whitish border; ears nearly naked posteriorly. Limbs strongly rufous 
externally, inside much paler and more or less varied with white. Tail 
like the back above, yellowish- brown below. 
The most striking peculiarity of this form is the shortness of the ears, 
which are much shorter than in any other species of Lepus with which I am 
acquainted. In size, it seems to be fully as small as L. trowbridget. The 
specimens are all more or less mutilated, so that the character of the tail 
cannot be well determined. The Lepus brasiliensis of von Frantzius, from 
Costa Rica, doubtless refers to this variety.
