244 PROFESSOR OWEN ON THE EXTERNAL CHARACTERS 
pp. 782-804. Entire skeletons of the full-grown Troglodytes Gorilla are now set up in 
the Museum of the College and in the British Museum. 
All the foregoing specimens were obtained from a part of the west coast of tropical 
Africa traversed by the rivers ‘‘ Fernandes Vas,” ‘‘ Danger,” and ‘‘ Gaboon,” in lati- 
tudes 1° to 10° N. and 1° to 15° S. 
A corresponding series of illustrations—first crania, then the skeleton, finally an 
entire specimen of the Troglodytes Gorilla—have successively reached the Museum of 
the Garden of Plants, Paris, and have afforded materials for interesting and instructive 
memoirs from the accomplished Professors in that noble establishment for extending 
and diffusing the science of natural history. 
Prof. de Blainville had caused a lithograph to be prepared of the skeleton of the 
Gorilla, shortly before his demise. His successor, Prof. Duvernoy, communicated a 
description of this skeleton to the Academy of Sciences in 1853, which is published, 
with some interesting particulars of the anatomy of the soft parts, in the ‘ Archives du 
Muséum d’Histoire Naturelle,’ tome vii. (1855). The Memoirs and Observations by 
the accomplished Professor of Mammalogy and Ornithology, Isidore Geoffroy St.-Hilaire, 
on the Gorilla will be found in the ‘Comptes Rendus de l’Académie des Sciences,’ 
January 19, 1852, and subsequent numbers ; in the ‘ Revue de Zoologie,’ No. ii. 1853 ; 
the whole being summed up in the part of his excellent ‘ Description des Mammiféres 
nouveaux,’ &c., 4to, which appeared in vol. x. of the ‘ Archives du Muséum,’ 1858. 
The differences in the results of the observations by the American, French, and 
English authors relate chiefly to the interpretation of the facts observed. Dr. Wyman 
agrees with me in referring the Gorilla to the same genus as the Chimpanzee, but he 
differs in regarding the latter as being more nearly allied to the Human kind. Professors 
I. Geoffroy St.-Hilaire and Duvernoy consider the differences in the osteology, dentition, 
and external characters of the Gorilla to be of generic importance’, and enter it in the 
Zoological Catalogue as Gorilla Gina, the nomen triviale being taken from ‘ Weggeena,’ 
‘Ngina’ and ‘ Djina,’ as the name of the beast in the Gaboon tongue has been di- 
versely written by voyagers. The French naturalists also concur with the American 
in placing the Gorilla below the Chimpanzee in the scale. I propose to discuss these 
questions at the conclusion of the present paper, and to test the notion current in some 
works that the long-armed Apes (Hylobates), and not the Orangs or Chimpanzees, 
are the most anthropoid of Quadrumana. 
The young male Gorilla, here described, was killed by natives in the interior of the 
Gaboon, and brought down to the port entire: it was at once immersed in a cask of 
' The main discrepancy, in regard to matter of fact, is that the arms of the Gorilla are stated by Isid. Geoffroy 
to be much longer, whilst I found them to be relatively shorter, than those of the Chimpanzee.
