Bulletin American Museum of Natural History. [Vol. XIII. 



Larger than C. cinereus, with the tips of the hairs of the dorsal surface dark 

 chestnut brown instead of rufous brown, and the lower parts more strongly yel- 

 lowish. Head and body in male, 180 mm. ; tail, 250 ; hind foot (without 

 claws), 25. 



Known only from Costa Rica. 



It may be of interest to state in this connection that what may 

 be fairly considered as the type of Didelphis cinerea Temminck 

 the mounted specimen sent to Temminck by Wied (cf. Wied 

 Beitrage zur Naturg. von Bras., II, 1826, p. 409, footnote) for 

 description is now in this Museum, it having been received as 

 a part of the Maximilian Collection, purchased in 1870. It is in 

 poor condition, having suffered from long exposure as a mounted 

 specimen, but it still has attached to it Wied's original label, 

 which bears the legend : " No. 33, Mas. Jupati." ' 



It is without doubt the type of Wied's description of the 

 species (/. c. y pp. 406-411), and certainly a cotype of Temminck's 

 original description (Monog. de Mamm., 1825, p. 46) ; he must, 

 however, have described the female from another specimen, from 

 Bahia, loaned him, as he states, by the Vienna Museum. 



1 Says Wied, " Dieses Beutelthier lebt im ostlichen Brasilien. Ich erhielt es in den 

 Waldern des Mucuri zu Morro d ' A zara^ wo man es unter der Benennung Jupati mil 

 den iibrigen verwandten Arten verwechselt" (/. c., p. 410).
