[With a Plate.] 
Since my last notice of Siwalik Mammalia,^ another collection has been 
received from Mr. Theobald, and a few interesting teeth have been obtained 
throngh Mr. Blanford from Sind. Many of Mr. Theobald’s specimens have 
added considerably to our knowledge of the dentition and osteology' of previously 
known species. On the present occasion I shall only very' briefly notice the most 
interesting of the majority of the new specimens, reserving their fuller descrip¬ 
tion for a future occasion, when I shall have an opportunity of giving figures of 
them. One specimen, howevci-—the jaw of a large monkey—is of so interesting 
a nature, that I have given a figure of it here, as it would otherwise have been long 
before I should have been enabled to do so. On the same plate 1 have likewise had 
drawn the molars of the Macaens and the Wikoniys described in my last notice. 
Among the rarer specimens is the greater portion of one side of the lower 
jaw of AtUhracoUtcriuni puiijalie'iise, showing the three true molars. 
PRIMATES. 
Palieowthecus sivalel’sis, n. gen. nobis. 
The most interesting specimen in the whole of Mr. Theobald’s Siwalik col¬ 
lection is the fragmentary palate of a large anthropoid ape, represented in figures 
1 and 6 of the accompanying plate. This specimen is of the highest intere.st, 
because, with the exception of a single canine tooth obtained years ago by Dr. 
Falconer from the Siwaliks, it is the only specimen which affords us any evidence 
of the former existence of anthropoid apes in India, or indeed, if we except 
Dryopitheous and the smaller genera, in the whole world. 
The specimen was obtained by Mr. Theobald from the Siwaliks of tho 
Punjab, somewhere near the village of Jabi, though I do not know tho iirecise 
locality; it was oiiginally in three fragments, but two of them have been united ; 
and as the fractures are ipiite recent, I presume that the specimen was broken uji 
by the natives in extracting it from its matrix. Tho portion that remains shows 
the greater part of the right maxilla, broken near the centre of the palate, and 
superiorly at the zygomatic root; the second fragment is a portion of the 
left maxilla; in the figure the two fragments have been placed in their relative 
position in the proportions of the palate of the living Orang. 
The fragment of the left maxilla contains the complete penultimate, and tho 
bases of the first and last molars. The right maxilla exhibits the entire dental 
series, from tho outer incisor to the last molar ; the o-own of the incisor, of the 
penultimate premolar, and the summit of the canine have been broken off; the 
penultimate molar has the centre of its crown somewhat decayed. The premo¬ 
lars arc two in number, which shows that the specimen belong.? to the Caturhino
