part 3 .] Lydekker: Fossil Mammalian Fauna of India and Burma. 91 
The next formation on the list is the Mammaliferous series of Pegu and the Irawadi 
river: fossils from these beds have been described and figured by Dr. Falconer (“Fauna 
Ant. Sival.” and “ Pal. Mem.”), and by Mr. Clift (Trans. Geol. Soe., London, 2nd series, vol. 
4); several new species of Mammals from this district are contained in the collection of the 
Indian Museum, obtained by Mr. W. T. Blanford and Mr. W. Theobald. The following list 
contains only those species of which the locality is certain :— 
Pkoboscidia. 
Stegodon Cliftii, Falc. Mastodon latidens, Falc. 
Mastodon sivalensis, Falc. 
Perissodactyla. 
Rhinoceros n. sp. mihi, Ind. Mus. Equus sp. Ind. Mus. 
Acerotherium perimense, Falc. Tapirus, Clift. 
Artiodactyla. 
Hexaprotodon iravadicum, Falc. Bos. sp. Ind. Mus. 
Merycopotamus dissimilis, Falc. Cervus sp. Ind. Mus. 
Yishnutherium iravadicum n. gen. 
mihi. 
Carnivora. 
Ursus sp. Indian Museum. 
The fauna of the (probably) Siwalik strata of the Nifci Pass and Tibet is only known 
from a few fragments of bone described by Dr. Falconer (“ Pal. Mem., Vol. I, p. 175), and 
from certain fossils collected by General Straohey (Quar, Journ. Geol. Soc., London, Vol. VII, 
p. 292); these comprise remains of a species of Rhinoceros, and of a ruminant allied to Ovis 
or Capra. 
The mammaliferous strata of Sind, with which I should be disposed to group those of 
Kach, have been recently described by Mr. W. T. Blauford (Rec. Geol. Surv., India, Vol. 
IX, pt. 1) under the name of Manokhar beds, which he correlates with the Sub-Himalayan 
Siwaliks; the only genera which I can at present identify among the numerous fragments of 
bones collected by Mr. Fedden from these deposits are the following : — 
Proboscidia. 
Mastodon latidens, Falc. Stegodon sp. 
Dinotherium sp. mihi. 
Perissodactyla. 
Rhinoceros, 2 sp. mihi. Listriodon sp. 
Artiodactyla. 
Merycopotamus sp. mihi. Ruminant sp. (astragalus.) 
Chalicotherium. sp. 
The last beds that I have introduced into the pliocene group are the mammaliferous 
gravels of Perim Island, in the Gulf of Cambay; most of the species were noticed by 
Falconer ; the list comprises— 
Proboscidia. 
Mastodon latidens Falc. Dinotherium iudicum, Falc. 
Mastodon perimensis Falc. 
Perissodactyla 
Acerotherium perimense, Falc. Rhinoceros sp. non-des.
