LEPORIDiE— LEPUS BRASILIENSIS VAE. 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. trowbridgei. The 

 specimens are all more or less mutilated, so that the character of the tail 

 cannot be well determined. The Lepus brasiliemis of von Frantzius, from 

 Costa Rica, doubtless refers to this variety.
