W. I. H. Rosenberg, 27th Nov., 1896. 
This handsome Lchimys differs from Tomes’s EH. semi- 
spinosus*, also from Ecuador, but without exact locality, by 
its richer rufous colour, the uniform distribution of the spines 
over the back and flanks, the much greater length and strength 
of the spines themselves, the nakedness of the tail, the struc- 
ture of the posterior nasal region, and the flatter bullae. In 
all these points the Bogota Echimys assigned last year T to 
Ei. semispinosus agrees much better with Tomes’s description 
than does that brought home by Mr. Rosenberg, in spite of 
the Heuadorean locality of the latter. 
Lepus andinus, sp. n. 
Size small, about as in L. sy/vaticus; much larger than in 
L. brasiliensis. General tone of colour dusky, the markings 
dull and inconspicuous. Forehead suffused with brownish ; 
cheeks and sides of neck ashy grey. Nape dull rufous. 
Back rather more heavily lined with black than in Z. sylvaéd- 
cus, the bases of the hairs very dark slaty. Rump with a 
dull reddish suffusion, which passes down on the legs to the 
heels. Chin and belly dull whitish, the hairs slaty for more 
than half their length; chest dull slaty grey, relieved by a 
few buffy hairs. ars rather short, though longer than in 
L. brasiliensis, grey basally, blackish brown for their terminal 
halves. Outside of forearm dull rufous, hands and feet 
whitish. ‘Tail a mere stump, hidden in the fur, coloured like 
the rump. 
Skull rather similar in general proportions to that of 
L. sylvaticus. Interorbital region slightly concave. Post-
