Dasypterus ega, typical form. 
General colour buffy white, without or with scarcely any 
dark at the bases of the hairs. 
Hab. Amazonian Valley and Pernambuco, from which 
latter place came the type of Tomes’s Lasturus caudatus *. 
Other Brazilian specimens in spirit seem referable to this 
form. 
Dasypterus ega argentinus, subsp. n. 
General colour dull buffy, near Ridgway’s “ cream-buff,” 
but dirtier ; not unlike that of ega. But the dorsal hairs are 
prominently black at their bases and finely black at their 
tips. Ilead more whitish grey than back, the lips slightly 
darker. Hairs on interfemoral dull yellowish. Under surface 
like upper, but the hairs without black tips. 
Forearm of type 44°5 millim. 
Hab. Goya, Corrientes, Argentina. 
Type. Male. B.M. no. 98. 3.4.9. Collected 29th March, 
1896, by Mr. R. Perrens. Two specimens. ' 
This southern form differs from true ega by its paler colour, 
still paler head, and the prominent dark bases to the dorsal 
hairs, these dark bases being nearly or quite obsolete in the 
Amazonian form. 
Besides the skins, a number of specimens in spirit from 
the same subregion appear to be similarly coloured. Thus I 
should refer to argentinus examples in the British Museum 
from the Bolivian Chaco (Borelli), Paraguayan Chaco 
(Boggiant), and Esperanza, Sante Fé (Lindner), and no 
doubt all members of this species recorded from Argentina 
belong to the present subspecies. 
It is interesting to note that the paler forms ranthinus and 
argentinus are at the two extremes of the range of the species, 
and the dark subspecies panamensis and fuscatus occupy an 
intermediate geographical position. 
Felis pajeros crucina, subsp. n. 
It has been noticed by many authors, notably d’Orbigny 
and Gervais in 1844+, and Elliot { in 1888, that different 
specimens of the Pampas Cat varied noticeably in the 
character of their colour-markings—the southern ones differ- 
ing, as the first-named authors put it, by the less fulvous tint
