1882. ] ON MAMMALIA FROM CENTRAL MEXICO. 371 
3. On a small Collection of Mammalia from Central Mexico. 
By Oxprietp Tuomas, F.Z.S., British Museum. 
[Received April 3, 1882.] 
Mr. A. Forrer, one of Messrs. Salvin and Godman’s collectors, 
has recently sent to London a small collection of Mammalia from the 
State of Durango, Central Mexico ; and I have been asked to publish 
a list of the species contained in it, in order that any additional in- 
formation to be gained from a collection made in such an interesting 
locality might be incorporated in the forthcoming Introduction to the 
Mammalian volume of the ‘Biologia Centrali-Americana. The 
specimens were all collected either at Ciudad, a village on the Sierra 
Madre, 8100 feet above the sea, or at Ventanas, another village in 
the same district, but only 2000 feet in altitude. 
It is noteworthy that, of the twelve species in the collection the 
ranges of which extend beyond Mexico into either North or Central 
America, just half are Nearctic and half Neotropical, and that, in 
the case of no less than seven of them, their discovery at Durango 
adds considerably to their hitherto known ranges. Of these seven, 
four are Neotropical and were obtained, with the exception of the 
Raccoon, at the comparatively lowland village of Ventanas, while the 
other three, of Nearctic origin, were all found at Ciudad, high up in 
the mountains. 
1. VESPERUGO SEROTINUs, var. FuscUS, Beauv. 
Two specimens. Ciudad. 
2. NATALUS STRAMINEUS, Gray. 
Six specimens. Ventanas. 
Not hitherto recorded north of Mirador, Vera Cruz. 
From this series it would appear that the bright orange or straw- 
colour from which the species derives its name, is confined to the 
adult males, the females being simply pale grey. 
3. ARTIBEUS CINEREUS, Gerv. 
Two specimens. Ventanas. 
This is the most northern locality recorded. There are other 
specimens from Mexico in the British Museum and elsewhere; but 
these seem mostly to have been collected in Southern Mexico, and 
have in no case any exact locality noted. 
4, VULPES VIRGINIANUS, Schr. 
Two specimens. Ciudad, July 21 and Sept. 30, 1881. 
5. Procyon cANcRIvoRuws, Cuv. 
One specimen. Ciudad, Sept. 16, 1881.

Cent.-Am., Mamm. Supp. p. 208. 
6. Meruiris MAcruRA, Licht. 
Two specimens. Ciudad, Sept. 14 and Oct. 1, 1881.
