reptiles. And it must be admitted at onee that the facts dealt 
with in the present communication do not conform with any 
certainty to one view or to the other. On the whole, however, 
they seem to point to the Lacertilian; since from that type 
the remaining schemes of encephalic arterial arrangement can 
be derived, while the extraordinary modification of the basilar 
artery in Z'estudo, found nowhere else, would seem for that very 
reason to be a divergence from the original condition. 
2. On the Nomenclature of the Anthropoid Apes as proposed 
by the Hon. Walter Rothschild. By Sir H. H. 
JouNnsToN, G.C.M.G., K.C.B., F.Z.S. 
[Received May 5, 1905. | 
I should like to make a few remarks on the admirable paper 
written on this subject by Mr. Walter Rothschild, which has just 
appeared in the ‘ Proceedings’ (1904, vol. ii. p. 413). Unfortu- 
nately, I did not know that this paper was going to be read 
in December 1904, or I should have endeavoured to be present. 
T am disposed in a general way to agree with Mr. Rothschild’s 
classification of the great Apes of Africa. I have only one 
criticism to offer with respect to the nomenclature of the 
Jhimpanzees. Since Mr. Rothschild has done so much to revise, 
revive, and establish the nomenclature of these Apes, I should lke 
to see him introduce a more rational spelling into the third of his 
species of Chimpanzees—the Bald Chimpanzee, which he gives, 
following Du Chaillu, as Simia koolookamba. Du Chaillu was 
very inaccurate in his transcription of African words, and he used 
the cumbrous system of English transliteration which prevailed 
until the rational spelling was introduced thirty or forty years 
ago by various scientific societies and departments of the Govern- 
ment. Koolookamba is really two words, which are pronounced 
nkulu-nkamba. J think that this spelling might stand in 
preference to Koolookamba [Simia nkulunkamba). 
A much more serious point, however, is the generic name which 
Mr. Rothschild gives to the Orangs—Pongo. Mr. Rothschild is 
undoubtedly right in reviving Simia as the most appropriate and 
the earliest name for the Chimpanzee genus, to which it was 
applied in the first instance by Linneus. Linneus evidently 
thought that the differences between the Chimpanzee and the 
Orang, which animal was later brought to his notice, were not more 
than specific, so that he included the Orang in the Chimpanzee 
genus. Much later, in 1799, Lacépéde applied the generic name 
Pongo to the Orangs; and although in the same year the Orang 
genus was named Satyrus, Mr. Rothschild prefers Pongo to this 
very appropriate designation, and wishes to establish Pongo as the 
generic name for the Orangs. I would certainly protest against 
this. There is much to connect the Satyr of the Classical world 
and Medizval mummeries with traditions of a red-haired man-of-
