dimensions (in millim.) of the Ape " A," together with the corre- 

 sponding figures relating to three undoubted Gorillas at Cambridge, 

 two of which, however, are immature. And I have added the corre- 

 sponding figures for "Johanna " for the sake of comparison. Three 

 indices show marked contrasts between "A" and undoubted 

 Gorillas. 



In comparing " A " with undoubted Gorillas, one may also 

 specially remark the palmar breadth : this is very much less than 

 in a Gorilla at Cambridge of rather greater size, viz. " Cy," whereas 

 the pollex in " A " is much longer than in this Gorilla. 



After ascertainiug, however, that, from evidence suppHed by 

 teeth, by facial features, and by the extremities, our specimen "A," 

 while in some respects intermediate, yet resembles the Chimpanzee 

 rather than the Gorilla, it is not encouraging to find Hartmann 

 in 1876, after an extended series of observations, pronouncing on 

 none of these characters as really of specific import. Thus he 

 states \ for instance, that whereas in Chimpanzees large ears are 

 the rule, yet individuals with small ears are not unknown, and 

 in fact he illustrates this (see fig. 3, p. 991) ; whereas again in 

 Gorillas, though small ears are usual, one sometimes finds examples 

 in which these appendages are of large size. 



But yet on finding the coincidence of so many characteristics 

 of Chimpanzee as in this animal, one may well be excused 

 hesitation in continuing to regard the specimen as a Gorilla. 



However, it can hardly be described as an ordinary example of 

 Anthroj)o/)it7iecus troglodytes ; and I am inclined to think, in the 

 absence of contradictory evidence, that we have here a specimen 

 of Du Chaillu's Kooloo-Kamba. Its great size gives it some claim 

 to an intermediate position between A, troglodytes and A. gorilla. 



But if an intermediate form, it differs appreciably from members 

 of another group of intermediate forms which we may call the 

 Mafuka group, and which is constituted by Mafuka, Johanna, and 

 Hartmaun's example No. 1 (c/. fig. 7, p. 991).
