Canis thous angulensis, subsp. n. 
A small form of the C. thous* group, with short stoutly 
built skull, small flesh-tooth, and pale-coloured limbs. 
Size smaller than in true C. thous or its Brazilian represen- 
tative C.t. melampus tT. General colour much as in the latter, 
but even more strongly suffused with fulvous. Hairs of 
dorsal area elongated, annulated with black and white, and 
with broad black tips; hairs of sides similar but shorter. 
Underfur dull buffy, becoming ochraceous buff on the promi- 
nent postauricular patches. Under surface dirty buffy. 
Snout not blackened, scarcely darker than the forehead. 
Back of ears dark ochraceous buff, without blacker patches. 
Upper surface of hands and feet dull ochraceous buffy, with 
scarcely a trace of darker marking; below, the palms and 
soles are inconspicuously blackened. ‘Tail bushy, coloured 
above like the dorsal area, below like the belly, its terminal 
hairs broadly black. 
Skull very stoutly built, conspicuously shorter than in 
either thous or melampus. Forehead not markedly convex, 
the frontal region far flatter than in the allied forms. Palate
