South-American species, observing that, besides its general golden-yellow hue, it might 
be “ always known by the distinct well-defined dorsal streak and by the yellow colour 
of its feet and tail” 2. A comparison, however, of the types of Cycloturus dorsalis in the 
British Museum with numerous South-American specimens shows that they all belong 
to one very variable species. Every gradation is present. An example obtained by 
Mr. Salvin in Guatemala has the fur as much washed with black and not more yellow in 
tint than in ordinary specimens of C. didactylus, while some South-American specimens 
have yellow feet and others a more or less distinct dorsal streak. In many individuals 
there is also a median band of blackish or reddish brown on the breast and belly. A 
form which at first sight seems more worthy of separation is dark grey in colour, with 
a brilliant silvery sheen and a distinct dark brown stripe down the nape and shoulders. 
But this also does not appear to be a geographical race, there being a specimen from 
Colombia in the British Museum and others from Guiana and Trinidad in the Museums 
of Copenhagen and Liibeck. 
According to these views, the Two-toed Anteater has a tolerably extensive range, 
though less so than the two last species, extending from Northern Brazil and Peru in 
the south to Costa Rica, Nicaragua, and Guatemala in the north. It does not appear 
to have been hitherto recorded from Mexico. 
In Costa Rica Dr. v. Frantzius obtained this species only from the valley of Orosi, 
near Cartago, whence he received one living and several dead examples. The former 
proved to be strictly nocturnal in its habits; during the day it remained rolled up, 
hanging by its claws to one of the spars of its cage, but at night it clambered slowly but 
unweariedly round its place of confinement, evidently seeking for a means of escape. 
It obstinately refused all sorts of food, and was therefore killed after a few days. “In 
its mode of climbing,” says Dr. v. Frantzius, “and its custom of hanging by its claws 
with its body rolled together, it bears a great resemblance to the Cholepus; but its 
climbing-powers are greatly aided by its prehensile tail” °. 
Messrs. Godman and Salvin inform me that in Guatemala the Two-toed Anteater is 
restricted to the thick forests of Vera Paz, where it enjoys a considerable range in alti- 
tude; and they add that Mr. Sarg had received specimens from Yaxcabnal, in the 
northern part of Vera Paz, taken at an altitude of about 1200 feet above the sea, 
and also from the mountainous district of Puruld, at an elevation of from 4000 to 
5000 feet.
