points only 5 belong to this species. It apparently ranges thence 

 southward over the tableland to at least Zapotlan. 



29. Lepus floridanus subcinctus Miller. 



Sixteen specimens: Ojo de Agua, i specimen, Feb. 15; Estancia, 

 2 specimens, Feb. 21, March 17; Garabatos, 2 specimens, March 20, 

 22; Llanos e Casco, Tepic-Jalisco boundary, 2 specimens, March 28; 

 La Cienega, 2 specimens, April 15, 17; Las Canoas, 6 specimens, 

 Aug 4, 5, 13, 22; Los Masos, i specimen. 



External measurements: 5 males, total length, 409 (400-413); 

 head and body, 372 (362-381); tail vertebrae, 37 (33-38); hind foot 

 without claws, 84 (83-89); ear from notch, 63 (55-67); tip to tip of 

 ears distended laterally, 181 (171-191): 6 females, total length, 422 

 (406-438); head and body, 385 (368-400); tail vertebras, 37 (35-38); 

 hind foot without claws, 84 (83-86); tip to tip of ears distended 

 laterally, 188 (165-200). 



Skulls: 4 males, occipito-nasal length, 73 (71-77); zygomatic 

 breadth, 35 (34-37); parietal breadth (greatest width of braincase), 

 26 (25.3-27): 4 females, occipito-nasal length, 77 (76-80); zygomatic 

 breadth, 36.5 (36-37); parietal breadth, 27 (25-27.5). 



As. is often the case in this genus, the females average slightly 

 larger than the males. In the present case, however, the females 

 average slightly older than the males, although all are fully adult. 



Apparently this very distinct form of the L. floridanus group 

 agrees satisfactorily with L. /. subcinctus Miller, described from 

 "Nagrete, State of Michoacan, " not far from the Jalisco boundary.
