Mr. Waterhouse exhibited a new species of Squirrel from the So- 
ciety’s collection, and pointed out its distinguishing characters, which 
are as follows :— 
Scrurus pimipiatus. Sci. supra griseus fulvo lavatus, subtis fla- 
vus ; capite, corpore ad latera pedibusque rufescentibus ; caudd 
Sere corporis longitudinem equante, indutd pilis nigris, flavis atque

Hab. South America? 
This curiously-coloured species of Squirrel was purchased at a 
sale, and in the same lot were specimens of Sciurus estuans and Sc. 
Langsdorffii, well-known South American species; it is probable, 
therefore, it may be an inhabitant of the same country. Its fur is 
very short for a Squirrel, rather harsh, and less loose than in the 
generality of Squirrels : the back is gray, or what might be termed an 
iron-gray, having a rusty hue; on the upper part of the head the 
rust-like tint prevails, and the muzzle is almost entirely of a rich 
rust colour; the sides of the head and neck are of a golden-yellow 
tint, and the under parts of the body are yellow: a bright rust- 
coloured line runs along each side of the body, and separates the 
yellow colouring of the under parts from the iron-gray of the upper : 
on the outer sides of the limbs, and on the feet, a rich deep golden- 
yellow hue prevails. The tail is apparently cylindrical, and not 
bushy ; the prevailing hue of the hairs is deep rust colour, but they 
are for the most part more or less broadly annulated with black in 
the middle. The ears are slightly pointed, and well clothed with 
golden-yellow hairs; those on the outer side are of a bright rust 
colour; they have no pencil of hairs at the tip. The hairs of the 
moustaches are numerous, long, and of a black colour. ‘The incisors 
of both upper and under jaws are deep orange. 
Mr. Fraser read his descriptions of, and observations upon, some 
new species of Insessorial Birds, belonging to the genus Agrilorhinus. 
‘In the northern parts of South America and in Mexico,” Mr. 
Fraser observed, ‘‘ are certain small birds, resembling the Warblers
