countries into two or more species did not present any permanent 
differences that could be relied upon; and I believed that the wart- 
hogs of different parts of Africa were only one species. 
Indeed Mr. Sclater himself gives P. ZEliani a very wide distri- 
bution, as he says it has been received by the Zoological Society 
from Zoulla, on the east coast, and Ashantee, on the wast coast of 
Africa 
I believe that what Mr. Sclater has figured as the type of P. ZEliani 
(Proc. Zool. Soc. 1869, tab. 20, and p. 277. f. 2) is only the usual 
form of the female of the African wart-hog. It is certainly not the 
P. Atliani (as distinguished from the P. cthiopicus) of Rüppell ; Ti 
it may be a distinct species, the male a which we have not yet r 
ceived, characterized by its naked ears; and as we have Mr. Sela- 
ter’s authority that s is a different species, I wank propose that it 
be called P. Sclate 
On the Genus Saurocetes. By Dr. BURMEISTER. 
(In a letter to Dr. J. E. Gray.) 
I have lately received a most interesting — of a fossil from 
the tertiary strata of Buenos Ayres, which proves to be a new genu 
of Zeuglodontide, which I have named Sanctsstes on account of its 
great resemblance to the gavial type of Crocodiles and its true ceta- 
ceous organization. 
The animal must have been much smaller than the North-Ameri- 
ean Zeuglodon; the under jaw, which is the only part known to me, 
is, from the middle to the hinder end, only two feet long: the teeth 
are all alike ; ; they have a single conoid corona, with two roots, which 
Zeuglodon. I will very soon send you a description and figure of 
this interesting fossil. 
Notice of a new Chilian Tortoise (Testudo chilensis). 
By Dr. J. E. Gray, F.R.S. 
Testudo (Gopher) chilensis. 
Shell depressed, dirty yellow; middle of the back flattened ; 
areola central; nuchal plate distinct; marginal plates shelving, 
with a very short keel; front and hinder marginal plates reflexed, 
making a serrated edge. One pair of supranasals, a triangular 
frontal plate between the eyes; fore legs with a large spur at the 
elbow-joint, and numerous conical spines on the underside of the 
thighs, two of which are larger than the rest. 
Testudo chilensis, Gray, P. Z. S. 1870, t. 
Hab. Chili. Living in the Zoological Gardens. 
Very like Peltastes sulcatus, but more depressed, and at once — 
by its broad fifth vertebral plate and narrower marginal plate
