5. Nore ON THE SPECIES OF THE GENUS PITHECIA, WITH THE 
DescripTIon OF A New Species, P. aupicans. By Dr. 
Joun Epwarp Gray, F.R.S., V.P.Z.S., perc. 
(Mammalia, P]. LXXXI.) 
Buffon, in his ‘ Histoire Naturelle,’ gives three figures of the 
animals of this genus ; they are not easily recognized ; and, according 
to M. I. Geoffroy, he is said to have figured one species and to have 
taken his description from another (see Cat. Méthod. p. 55). 
M. Geoffroy the elder, in his ‘ Tableau des Quadrumanes,’ pub- 
lished in 1812, noticed four species, viz. P. leucocephala, P. miri- 
quouina, P. rufiventer, and P. monachus. The specimens then in 
the collection on which: they were established were imperfect or 
young, and it has been found very difficult to assign these names 
with certainty to the specimens which have been recently collected. 
Dr. Kuhl, who took the trouble to examine the original specimens 
in the Paris Museum, and to study the species existing at that time, 
viz. 1820, after more carefully describing the specimens named by 
Geoffroy, and those received between 1812 and 1820 by the Paris 
Museum, and also those in the Prince Maximilian’s and Temminckian 
Museum at Leyden, added two others to Geoffroy’s list, viz. P. rufi- 
barbata, and P. ochrocephala (from a specimen in the Temminckian 
collection). M.'Temminck, however, has considered (and Fischer has 
followed his lead) that P. ochrocephala is the female or young of P. 
leucocephala, and P. rufibarbata the same as P. rufiventer of Geof- 
froy and Kuhl. _I think, from Dr. Kuhl’s description, that his ac- 
count of the subannulated hair may probably be correct,—the peculiar 
- pointed form of the tail, which Dr. Kuhl says distinguishes it from all 
other Pithecie, being dependent on its having been kept in a mena- 
gerie. But the description of P. ochrocephala does not agree with 
any specimens of the genus I have seen. In the division of the hair 
on the forehead it agrees with P. chrysocephala of Isidore Geoffroy ; 
but then, that species, as far as I have seen, never has the upper side 
of the tail and the outside of the limbs chestnut-brown. Can it be a 
Callithrix? 
I may here observe that the Pithecia miriquouina—which both 
Geoffroy and Kuhl describe from one specimen, if not more, in the 
Paris Museum, and which has been called Simia azara by Cuvier and 
Humboldt, and is referred by Dr. Kuhl to P. adusta of Mliger with 
doubt, and is evidently very distinct, according to these authors—has
