668 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [ Nov. 1, 
13, A Spider Monkey brought home from Trinidad, and presented 
to the Society by the Hon. Arthur Gordon, C.M.Z.S. and lately 
Governor of that colony, on the 14th of July. Mr. Gordon informs 
me, in reply to inquiries, that this Monkey was obtained for him by 
one of his correspondents from the upper part of the Caura River, a 
southern confluent of the Orinoco, and was considered to be a very 
rare species. I was inclined to refer it to Ate/es belzebuth of Geot- 
froy St.-Hilaire (Ann. d. Mus. vii. p. 271), and have inserted it in 
the Register under this name. But the animal having unfortunately 
died, and having been sent to the British Museum, is, as I am in- 
formed, considered by Dr. Gray to be probably a female of his 
Ateles bartlettii (P. Z. 8. 1867, p. 992, pl. xtvit.). 
I do not think this is probable. I take Dr. Gray’s Ateles bart- 
lettit to be the same as déeles variegatus of Wagner (Schreb. Suppl. 
i. p. 313, et Abh. Acad. Munich, v. p. 120), which was discovered 
by Johann Natterer on the Upper Rio Negro in 1831. Now 
Wagner’s description of dA. variegatus (which agrees exactly with 
A. bartlettii) was, as he informs us, taken from a temale; so that in 
this species the sexes must be nearly alike*. 
14. A young Hornbill, of a species closely allied to Buceros cylin- 
dricus, Temm.,—of which the bill only is figured in ‘ Planches Colo- 
riées’ (Pl. Col. 521), but the bird itself is described by Hartlaub 
(Orn. Westafr. p. 162),—and to B. fistulator, Cassin. 
As, however, it is not identical with either of these species, I 
subjoin a short diagnosis of it, which, together with the accompany- 
ing figure, taken from the living bird, will, I think, render it easily 
recognizable :— 
BUCEROS SUBCYLINDRICUS, Sp. nov. (Plate XXXIX.) 
Niger cristatus: capitis plumis albescente cinereo variegatis ; 
dorso postico, campterio alari et alarum dimidio apicali albis, 
remigibus tribus externis exceptis nigris: subtus niger ; ventre 
imo, tibiis et crisso albis; cauda alba: rectricibus duabus in- 
termediis totis, nist ad ipsum apicem, et rectricum lateralium 
SJascia lata basin versus nigris ; rostro et pedibus nigris ; rostri 
culmine elevato, valde compresso, cultrato, arcuato: iridibus 
rufis: long. tota 24, ale 11°5, caude@ 10), rostri a rictu 4, poll. 
Angl. et dec. 
Hab. Africa occidentalis. 
Obs. A B. eylindrico, capite maculato et rectricibus mediis nigris, 
a B. fistulatore capite maculato et secondariis omnino albis distin- 
guendus. 
15. A rare Southern Asiatic Blindsnake (Typhlops nigro-albus, 
Dum. et Bibron; Ginther, Ind. Rept. p. 172), purchased July 19th. 
The species was identified for us by Dr. Giinther, to whom the 
Society is greatly indebted for the determination of the Reptiles in 
their living collection. 
16. A second example of the new Kangaroo which I described
