cated a third species from E. Florida, to which he has given the 
name of M. Larirostris.* This species is recognized by Lesson 
and Fischer, but has been more recently denied by Blainville, 
who in referring to . in connection with two other species of the 
same group, (Mana s, Lamantin, Blainville,) L. du tabernacle 
and L. de olciociaas expresses himself, ‘‘ne regardaut nullement 
comme suffisamment distinct.’ 
The existence of this third species has been within a short time 
conclusively demonstrated by Prof. Agassiz, and the evidence on 
which this conclusion rests will soon be published in a memoir 
on those genera of Cetaceans whose remains have been found 
in the United States 
In the Proceedings of the Boston Society of oan —_ 
vol. ii, p. 198, is a notice by Dr. George A. Perkins of an animal 
captured in the Cavalla River, W. Africa, agate to the regal 
as Ne-hoo-le, and which Dr. Perkins referred to the genus Mana- 
tus. Ina note to that communication I stated, that this animal 
differed from all known species of Manatee, both in the number 
of the teeth which was for the molars $ 3, and i in the absence of 
nails on the paddles, as well as in other characters of subordinate 
value. In the sequel it will be seen however that the formula 
for the teeth was not correctly stated. The provisional name 0 
anatus nasutus was given to this supposed species. 
Quite recently, Dr. Perkins, on his return from Cape 
brought with him and presented to the Boston Society of A i 
History, an imperfect cranium of the same species, the lower jaw, 
me intermaxillary, nasal and temporal bones having been broken 
y the natives as they divided the carcass amongst themselves 
for food. A sufficient number of characteristic parts, OSES 
remain to demonstrate that the species, as formerly suspected, i 
anew one. In establishing the following characters, the aan 
in question has been compared with that of the Manatus senega- 
lensis, M. Americanus and M. latirostris: the first belonging 
to the Boston Society of Natural Eieory and the others to the 
Academy of Natural Sciences of Philadelphia.
