‘deavour to obtain specimens of it; and the result was that Captain 
George Wagstaff,had succeeded in procuring at the Gaboon river, 
and had presented to Mr. Stutchbury, three skulls of the large species 
and one of the smaller species of chimpanzee, all adult: and these 
skulls Mr. Stutchbury had transmitted for description and exhibition 
‘at the Zoological Society. 
One of the skulls of the large species (Troglodytes Savagei) was 
of a very old male: the length of the skull was 114 inches (0°29), 
with the molars worn nearly to the stumps, and the crown of the 
canine reduced, partly by fracture, partly by attrition, to its basal 
portion : its pulp had been inflamed and had produced ulceration of 
the alveolus. 
A second skull was also of a male, of equal size, with the full 
dentition of maturity, but with merely the summits of the cusps of 
the molars and the margins of the incisors slightly worn. The 
third skull of the Troglodytes Savagei was of a female, 9 inches 
(0°23) long, with the mature dentition, and with the molars not 
more worn than in the younger male. The fourth skull was of a 
female adult chimpanzee, 74 inches (0°185) in length, of the known 
species (Troglodytes niger), with the complete permanent dentition, 
and the teeth more abraded than in the two preceding skulls. 
The lower jaw was wanting in each of the foregoing specimens, 
and the occipital or basal part of the skull had. been more or less 
fractured in each; the skull of the young but full-grown male of 
the Troglodytes Savagei being the most perfect. 
Captain Wagstaff reached Bristol in a broken state of health, and 
died soon after his arrival. The only information which Mr. Stutch- 
bury was able to obtain from him was, that the natives, when they 
succeed in killing one of these chimpanzees, make a ‘fetish’ of the 
cranium. ‘The specimens bore indications of the sacred marks in 
‘broad red stripes crossed by a white stripe, of some pigment which 
could be washed off. Their superstitious reverence of these hideous 
remains of their formidable and dreaded enemy adds to the difficulty 
of obtaining specimens. 
Besides the young but mature skull of the male Troglodytes niger, 
of which the permanent dentition was figured in the author’s 
‘Odontography,’ he had compared with Mr. Stutchbury’s speci- 
mens of Troglodytes Savagei, a skull of a more aged male Troglodytes 
niger with the permanent dentition more worn than in the younger 
adult male of the Troglodytes Savagei. The results of a detailed 
comparison between the skulls of the adult males of the two species 
were then given. Besides the differences of size, as indicated in 
the subjoined ‘ Table of Dimensions,’ the following were among the 
characters establishing the specific distinction of the two chimpan- 
zees. With regard to the dentition, the author observed that, as 
in the smaller species of the Orangs of Borneo (Pzthecus Morio), the 
Incisive teeth of the smaller species of chimpanzee (Troglodytes 
niger) equalled in size those of the larger species (Troglodytes 
Savagei) ; but that the canines and the molars were considerably 
larger in the Troglodytes Savagei: the series of the five molar teeth
