REPORT ON ZOOLOGY, MDCCCXLII : 
long, pale at the base, then greyish-black; those of the head, neck, back, 
and root of the tail, with two or three broad yeHow-brown snbterrainal 
bands ; body 19" ; end of tail mutilated : from Fernando Po. 
Is. Geoffrey separates from Cereopithecus a peculiar genuS', 
Miopithecus {pum, minor). 
He gives, as its chief characteristics, in D’Orb. Diet. iii. p. 308, — Skull 
raised higher above the eye-sockets ; partition of the nose pretty broad ; 
nasal fossae opened downwards and sidewards; last grinders less than 
the anterior ones ; in the under jaw, only with three knobs, two anterior, 
and one posterior; similar arrangement in the upper jaw; size much 
inferior to that of the other apes of the Old World. The genus is 
founded upon the Simla talapoin. As a second species. Is. Geotfroy 
adds to it a Miopithecus capillatus^ very like to the first, but somewhat 
bigger ; colour reddish with a dash of olive, not green ; the back-hair, 
in its under half, black, not grey ; also wants the tufts of yellow side- 
ways inclined hair, which the Talapoin has on the cheeks. As the skull 
and teeth of the new species are not known, there remains an uncer- 
tainty whether it properly belongs to this genus. 
The Inuus speciosus has been fully described by Temminck 
in the Faun. Jap. Mam. p. 9. 
It agrees most nearly with the I. ecaudatus, but is ith less. This is 
the only species of ape in the Japanese islands, and not in aU localities. 
It is pretty common in the island Sikok, and in the province of Aki 
(island Nippon) ; in that of Kiusiu, the southernmost of this group ; it 
is found in the mountains of Figo; its geographical distribution wib, 
on this account, be bounded by 35° north latitude. It bves in herds, 
and is as docile as the I. ecaudatus. 
American Monkeys.— The reporter has already given the 
diagnoses of four new Brazilian species in these Archives 
(8 Jahrg. 1 Bd. p. 357). 
J. E. Gray has mentioned some species in the Ann. Nat. 
Hist. X. p. 256, viz. : — 
Eriodes frontatus ; no thumb on the hand ; reddish-brown, yello-wish- 
brown beneath ; forehead, elbows, knees, and the upper side of the arms 
and of the four hands, black. Young like the adult, but with long 
white hairs on the cheeks, and amongst the black hair on the forehead : 
habitat, South America. Captain Belcher. British Museum. Appears 
to be a good species. On the contrary, Gray’s Pithecia pogonias is 
nothing more than a young male or female of Pithecia leucocephala, 
which figures in the System already, under six different names at least.
