On a Collection of Bats from Para. 189 
limbs and tail. Fur thick and woolly, the specimens 
evidently in winter pelage. General colour nearest to 
Ridgway’s “ clay-colour,” therefore exceedingly different 
from the nearly “ drab-grey” of #. c. puma. ‘This colour is 
most vivid along the back, paler laterally on the sides, but 
there is nothing that can be called a distinct dorsal dark line. 
Under surface whitish fawn, the hairs sandy at their bases, 
whiter terminally. Face very much like back, darker 
markings practically obsolete; the usual lighter markings 
near the eye present but not conspicuous. ars of normal 
length, their backs uniformly whitish fawn, without darker 
markings. Outer sides of limbs like back, inner sides like 
belly ; ends of fingers and toes whitish, without any darker 
markings round the pads. ‘Tail proportionally very short, 
brownish clay-colour above, whitish below, the tip not or 
scarcely darker. 
Dimensions of the typical skin, which has been tanned 
and stretched, so that the measurements are merely approxi- 
mate :—Head and body 1370 millim., tail 530, ear 80. 
Hab. Santa Cruz, Patagonia; about 70 miles inland. 
Type. Female. B.M. no. 1. 8.12.1. Brought home by 
Mr. H. Prichard and presented by Mr. C. Arthur Pearson. 
The skin was bought by Mr. Prichard from Indians in the. 
region mentioned, so that neither flesh-measurements nor 
skull were obtained. 
The second skin is that of a young male, killed on the 
Senguer River, in March 1897, by one of the collectors from 
the La Plata Museum, by whom it was presented to the 
British Museum. Owing to its youth, its peculiarities had 
not been previously noticed. 
Fc. Pearsoni is distinguished from F. c. puma not only by 
its very different general colour, but also by its shorter tail, 
light-coloured ear-backs, and the absence of the dark markings 
round the digital pads. 
XXVII.—On a Collection of Bats from Para. 
By OLDFIELD THomAS, F.R.S. 
I owe to the kindness of Dr. E. A. Goeldi, Director of the 
Goeldi Museum, Para, the opportunity of working outa large 
number of bats obtained at that interesting locality, and have 
thought it worth while to givea list of them. The collection is 
especially rich in members of the genus Artibeus, of which 
no less than five are represented in it.
