 gri/zled ochraceous bnffj' (with a slight reddish tinge) overlaid with a thin

.S7i((// charachrs. — Skull large and heavy ; longer than in aztecui^ and about 

 the same length as in i/ucaliiiiicus but not so massive as in that form ; ros- 

 trum very broad, especially at outer end, but depth of rostrum proj)ortion- 

 ately small ; outer end of nasals broad and much less depressed than in 

 azlec>i>t,thu< adding to massive appearance of rostrum viewed from above ; 

 superior outline of skull posteriorly gently curved, about as in aztecas, but 

 much straighter and more flattened anteriorly ; interorbital width narrow ; 

 jugal heavy, with a well-marked groove ending anteriorly in a deej) pit;

 skin), 60. 



Cranial measurements of type : Occipito-nasal length, 80 ; basal length of 

 Hensel, 61 ; interorbital width, 1 8 ; parietal width, 2() ; length of nasals, 87 ; 

 width of nasals, 17 ; depth of rostrum at front base of molars, 15; width of

Spechnens exam ined. — Eleven. 



General notes. — With the exception of being a little darker coloi'ed, espe- 

 cially the rufous on the legs, and its larger size, the Chiapas cottontail bears 

 externally a close resendilance to L. f. azfecus, but its well-marked skull 

 characters are sufficient to distinguisli the two. The broad flat rostrum is 

 a strong character which is very distinctive. So far as known, this is the 

 southernmost subspecies of Lepus florldanua. In general size the skull of 

 cliinpensis is nearest that of uncatnnicus, but the broader, flatter rostrum, 

 narrower braincase, and smaller bullte distinguish it.
