M. TamManpnva. 
Head, shoulders, fore-limbs, outside of the hind-limbs, and middle 
third of the tail white ; a stripe from each side of the neck over the 
shoulder and remaining parts black ; tail but little longer than the 
body, its terminal third scaly. Varies chiefly by the diminution of 
the intensity of the black. 
I have found that the Yellow Ant-eater, hitherto considered to be one 
of the varieties of this species, differs remarkably in the length and size 
of the tail ; the ears also appear to be larger, but this latter character 
is less decisive, owing to the different degrees to which they may 
shrink when dry. A specimen in the British Museum, and one in 
that of this Society, resemble each other exactly, while a young pale 
specimen of M. Tamandua has a tail proportionally of the same length 
as the larger and darker individuals. Under these circumstances I 
have been induced to propose a name for the Yellow Ant-eater, deem- 
ing it probable that the species may be distinct. 
M. LoNGICAUDATA. 
General colour uniform light ochraceous, a paler line runs down 
the middle of the back ; tail nearly double the length of the body, 
its terminal half covered with small scales and a few scattered black 
hairs ; ears large, round, about one-third the length-.of the head. 
Although the flanks show a slightly darker reflection in certain di- 
rections of the light, there is no trace of the mark which runs across 
the shoulder. 
On referring to the figure, in Krusenstern’s Voyage (tab. 6 e), 
on which M. Desmarest founded his Myrmecophaga annulata, I find 
it to be a very excellent representation of a Coati-mondi, probably 
the brown species. The head is bent downwards, the tongue pro- 
truded, and curved beneath the left fore-foot ; from under the further 
side of the foot there comes a small twig of a tree, which, if it were 
not branched, would look like a continuation of the tongue. But 
the figure published in Griffith’s translation of the ‘ Régne Animal’ 
is not so easy to interpret. The general form of the body is more 
like that of an Ant-eater, though rather too long and slender ; the 
tapering head and the dark stripe from the end of the muzzle to the 
eye remind one of the Myrmecobius, which was not known until 
several years afterwards ; the tail is just such as a Coati-mondi might 
have supplied. The figure is said to have been drawn from a stuffed 
specimen, but the authors do not state where the specimen existed, 
and possibly may never have seen it. 
Cuvier asserts, with much probability, that the animal from which 
Buffon took his figure of the Tamandua was made up of the skin of a 
Coati-mondi, to which striped markings had been artificially applied. 
_ CycLoruurvs, Gray. 
Fore-feet with two toes, the outer one much the larger; “the pala- 
tines only meet below for two-thirds of their length, and the bony 
canal of the nares there terminates, the pterygoids not meeting, but 
presenting only two long parallel and little prominent crests.”
