CELOGENYS.—LEPUS. 175 
In Guatemala Messrs. Godman and Salvin tell me that the Tepescuinte is “a common 
species in the neighbourhood of Coban, where it gives good sport to the native hunters, 
who keep dogs for their pursuit—curs, it is true, of every shape, colour, and size, but 
valued by their owners for their powers of scent, their perseverance, and their sagacity. 
A Lepescuinte, when found, is either run by the dogs within shot of the hunter, or to 
ground, whence it is smoked out and either killed or started on a fresh run. Traps are 
often set in the forest for them, formed like a hole, the upper part being a heavy log 
weighted with stones, and kept up by some slight contrivance easily brushed away by 
the animal in its hurry to escape from the dogs. In the valley of the Rio Negro, or 
Chisoy, Calogenys paca is apparently very abundant; for in an Indian rancho on the 
banks of the river, on the road below San Cristobal, we found dozens of their singular 
skulls strung about the walls of the hut”. . 
Passing further to the northward, we find that Vera Cruz is given by Dr. Dugés as a 
locality for the Paca®, this being the only record, so far as I am aware, of its existence 
in Mexico. 
Suborder II. DUPLICIDENTATA. © 
The small but well-marked suborder of the double-toothed Rodents consists of only 
two families, the Lagomyide and the Leporide. Both are found in the Nearctic Region ; 
but only the latter is represented, and that very poorly, in South America. As will be 
seen presently, several species of Hare are found in the northern portion of our sub- 
region, but only two go so far south as Costa Rica.

The Hares form a very uatural family, too clearly defined and well known to require 
to be characterized, and too homogeneous to be broken up into separate genera. They 
are principally represented in our fauna by Nearctic types. Of nine well-ascertained 
North-American species, four range well into Central America,a fifth species appears to be 
peculiar to the subregion, and a stath is also found in Colombia. With the exception 
of a closely allied Brazilian form, the latter is the only Hare yet discovered on the 
South-American continent.
