The Grey Fox, which Professor Baird describes as being generally distributed through- 
out the United States south of Pennsylvania‘, extends its range through Mexico and 
Central America. It was found not uncommonly in the north of the former country 
by the naturalists of the Boundary Survey®; Dr. Dugés records it from the States of 
Guanajuato and Guadalajara® ; and there are specimens from Yucatan and Tehuantepec 
in the National Museum at Washington". In Guatemala, Messrs. Godman and Salvin 
found it to be a very common species, specimens being often obtained by Indian hunters, 
They once saw one in the forest near Duefias, which ran along the path in front of 
them, and then escaped into the bush. 
The British Museum contains an example obtained by Dyson in Honduras; and Dr. 
v. Frantzius states that it is found in Costa Rica, where it is has usurped the name of 
Tigrillo, properly applied to the Tiger-Cats. It there frequents the neighbourhood of 
human habitations, sheltering itself in clefts of rocks or in holes in stone walls, and is 
very destructive to poultry. Dr. v. Frantzius found four cubs in such a hole in the 
month of March; these had a woolly coat, blackish-grey above and whitish below, 
with greyish-brown markings on the muzzle and feet”. 
In 1857, Professor Baird described a small Grey Fox from the Island of San Miguel | 
as a new species, Vulpes littoralis, differing from V. virginianus in its much smaller 
size and softer fur, in its ears not being rusty in colour, and in some minor cranial cha- 
racters’.| Mr. Allen, however, after comparison with other specimens, believes the Coast 
Fox to be merely a local variety of V. virginianus, a species which gradually diminishes 
in size to the southward. A well-matured skull from Yucatan he finds to be even 
smaller than the Californian examples in the National Museum; and he states that 
“ the.small insular race known as ‘ littoralis, from the islands off the coast of Southern 
California, comes in between the Tehuantepec specimens and the example from 
Merida” !, Another specimen from Yucatan, recently submitted to me by M. Boucard, 
is somewhat larger than the one described by Mr, Allen, and differs in no respect save 
size from the usual type of V. virginianus. | |
