EDENTATA. 161 
united to the acromion. The arms are double the length of the 
legs ; the hair on the head, back, and limbs is long, coarse, 
and non-elastic, something like dried hay, which gives it a most 
hideous aspect. Its colour is grey, the back being frequently 
spotted with white and brown. It is as large as a Cat, and is 
the only mammiferous animal known which has nine cervical 
vertebra. 
There is an Ai called the Dos brulé, from the circumstance 
of having between the shoulders a black spot, surrounded with 
fawn colour; but, according to Temminck, it is only a variety ; 
the appearance alluded to resulting from the wearing away of 
the long hair on the shoulder. The Black Collared Ai, how- 
ever,— Brad. torquatus, Geoff. Ann. Mus., Schreb, LX XIV, A, 
is a species that is very distinct, even in the bony structure of 
the head. 
M. Fr. Cuvier applies the name of Brapyrus to those species 
only which have two nails to the fore feet, the Cuotzpus, Illig. 
Their canini are larger and more pointed, and they are wholly des- 
titute of a tail. There is but one known. 
B. didactylus, L.; Buff. XIII, i. (The Unau.) Which is 
somewhat less unfortunately organized than the Ai. Its arms 
are not so long, and its clavicles are complete; there are fewer 
bones of the feet and hands which become soldered together ; 
the muzzle is more elongated, &c. It is larger than the Ai by 
one half, and is of a uniform greyish-brown, which sometimes 
has a reddish tint. 
These two animals are natives of the hot parts of America, 
and, long ere this, would probably have been destroyed by the 
numerous Carnivora of that country, had they not possessed 
some means of defence in their nails.(1) 
Fossil skeletons of two Edentata of great size have been 
(1) It is singular that the B. didactylus was not known before the time of Seba, 
~ and that fora long time naturalists obstinately persisted in referring it, on the au- 
thority of that ignorant collector, to Ceylon. Erxleben has maintained its African 
origin, having mistaken it for the Poto of Bosmann, whichis a Galago. (See this 
last genus.) It is a fact that the Unau is only found in South America. 
Shaw, Gen. Zool., under the name of Brad. ursinus, has described an animal of 
_ which Illiger has made his genus Prochylus. M. Buchanan, Trav. in the Mysore, 
Vol. Ul, p. 198, has shown it to be a true Bear, and in fact we have satisfied our- 
selves by inspecting the cranium of the very individual described by Shaw, that it 
was a Bear of the species termed Pick ppg had lost its incisors, See 
Ursus, &c.
