18$2.] ON MAMMALS AND BIRDS FROM EASTERN PERU. 373 
4. On some Mammals and Birds collected by Mr. J. Haux- 
well in Eastern Peru. By Epwarp Barruerr, Curator 
of the Maidstone Museum. 
[Received March 29, 1882. ] 
Some time ago I received a collection of mammals and birds from 
Mr. J. Hauxwell, collected by him in the neighbourhood of Nauta, 
Elvira, and Loretoyacu, on the banks of the Peruvian Amazons. I 
regret to say that, my time having been otherwise occupied, I have 
been prevented from bringing an account of this collection before the 
Society sooner. However, I think that my notes will be acceptable 
to those interested in distribution (to which I have already contri- 
buted largely), as increasing our knowledge of the avifauna of that 
vast region. 
The collection contained 136 species, 121 of which had been 
previously obtained during my four years’ residence in Peru. But 
there are 15 species among them not mentioned in my list (which 
appeared in the ‘ Proceedings’ of the Society for 1873, p. 252); and 
two of the 15 appear to be new to science, although closely allied to 
forms already known from the same localities. One belongs to the 
genus Thamnophilus, and the other to the genus Crypturus. 
It is not my intention to give the names of the 121 species, 
because they are enumerated in the catalogue above alluded to, but 
only to refer to those which do not appear in that list. 
By the list above referred to I find that the number of species 
collected by Mr. Bates, Hauxwell, and myself, was 473. L now add 
15 species, raising the total to 488. 
I here take the opportunity of thanking Mr. Osbert Salvin for 
his kindness in determining some of the more obscure species, and 
for pronouncing the two birds new or undetermined. 
MamMALs. 
The three mammals new to the list were as follows :—Ateles 
variegata, Wagner (=Ateles bartletti, Gray); Phyllostoma has- 
tatum (Pall.); and Galera barbara, Retz.,—all from Elvira.
