226 SOUTH-AMERICAN MAMMALS. 



The type of Azara's Micouré laineux is from Paraguay , 

 Caazapa; another specimen — a male — from the neigh- 

 borhood of Sainte Marie de la Foi has been presented to 

 d'Azara. This species also was represented in Rengger's col- 

 lections from Paraguay, Villa Rica. Mr. Oldfield Thomas 

 informs me that there are several specimens in the Bri- 

 tish-Museum, from Panama (Chefo) , Columbia (Medellin), 

 Ecuador and Peruvian Amazons (Chamicuros). Natterer's 

 specimen in the Vienna-Museum is from Cai9ara, Sou- 

 thern-Brazil; it was the first specimen of this species in 

 any European-Museum. Another specimen — a male — 

 from Natterer's voyage — if Sii ]ea,si Didelphys ochro pus Nat- 

 terer is a mere variety of D. lanigera , as 1 suppose — is 

 from Barra do Rio-Negro. Mr. Huet writes me that there 

 is a single specimen — a female — in the Paris-Museum, 

 from J. Verreaux in 1854 and indigue comme venant d' Austra- 

 lië! In the Leyden Museum is a stuffed specimen — a 

 male — from Demerara, British Guiana (Frank, 1877). 

 Our other specimen — a female — is from Ecuador or 

 Northern Peru, 4 August 1881, collected by Mr. J. H. 



The above given localities show that this species has a 

 very wide area of geographical distribution, viz. : from Pa- 

 nama to Paraguay and from Peru to British Guiana. 



The species has been figured under the name of Didel- 

 phys ornata Tschudi — I believe with Mr. Oldfield Thomas 

 that the specimen described by Tschudi in his Fauna Pe- 

 ruana under this new name belongs to our .species — but 

 this figure cannot be called very correct, especially the 

 colors do not agree with the description. Didelphys derhiana 

 Waterhouse belongs perhaps too to our species, but I never 

 saw the figure in the Naturalist's Library (Marsupialia) 

 Vol. XI , PI. 2 (Waterhouse). Alston's figure of DideJphys 

 derhiana (Biologia centrali-americana , pi. XXII) is taken 

 from an original sketch from the life by Mr. Smit , and 

 lets no doubt that the female and young specimen?! , living 

 in May 1877 in the Zoological Society's Gardens, belonged 

 to the true Didelphys lanigera. Both our specimens show
