All the four toes placed forward. 
Corius, Linn. Bill short: the upper mandible widened 
at the base, but very convex above: culmen elevated, 
_and arched downwards : commissure entire: the mar- 
gin of the upper mandible folding over the edges, and 
almost hiding the lower, which is very thin and 
straight. Nostrils large, basal, naked ; the aperture 
linear, oblique, and a little removed from the base of 
the bill. Wings rather short, pointed. Tail very 
long, cuneated ; the feathers very narrow, and some- 
what rigid. Feet strong, four-toed. The exterior 
toe and the hallux (placed on the inner side) inserted” 
in an oblique direction. Claws slender, rather acute,

* Imperfect as is the above account, taken from the obscure descriptiO1 
and rude figure of Dr. Latham, I feel fully persuaded that this is a per. 
fectly distinct type from the true Phytotome of the New World. The dif. 
ference of food alone sanctions me in this opinion, if, as it is stated, t 
first lives upon the roots of plants, and the latter upon kernels of fruits.
