1882.] ON MAMMALIA FROM CENTRAL MEXICO. 371 



3. On a small Collection of Mammalia from Central Mexico. 

 By Oldfield Thomas, F.Z.S., British Museum. 



[Eeceived 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 Duraugo, 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 confiaed 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 CANCRIVORUS, CuV. 



One specimen. Ciudad, Sept. 16, 1881.

 Cent.-Am., Mamm. Supp. p. 208. 



6. Mephitis macrura, Licht. 



Two s})ecimens. Ciudad, Sept. II and Oct. 1, 1881.
