Introductory. — Since the publication of the notice of the remains of this 
species in the Indian Museum in the first volume of this work, 1 two additional 
specimens have been temporarily acquired by the museum, which are of such import- 
ance as to merit a short notice here, although it is unnecessary to give figures of 
them. The specimens, which were obtained from the Siwaliks of Perim Island, — 
the source of the specimens on which the species was founded — belong to the Bombay 
Branch of the Royal Asiatic Society, to the courtesy of the Council of which body 
the author is indebted for the opportunity of noticing them here : they have been 
already briefly alluded to in the ‘Records’ of our Survey. 2 The specimens comprise 
a portion of a maxilla, and of a mandible, and will be noticed separately. 
Fragment of maxilla. — The fragment of a maxilla consists of the hinder portion 
of the left side, containing the second and third true molars, and the base of the 
first. The teeth are of large size and in a somewhat battered condition : each tooth 
bears two ridges, and large fore-and-aft talons. The dimensions of the teeth are 
as follows : — 
Length of 2nd molar 3'95 
Width of „ 3-8 
Length of 3rd „ ' 3 6 
Width of „ „ 3-7 
These dimensions indicate an animal fully as large as the European F. giganteum. 
The size of the teeth in the Perim specimen agrees with that of the fragmentary 
specimen represented in plate XXXI, figure 1, of the first volume of this work. 
Mandible. — The fragment of the mandible consists of the middle portion of 
the right ramus, showing the first and second true molars, 3 and the base of the last 
premolar.

3 In the already quoted note in the ‘ Records,’ this specimen is erroneously stated to show the two last, in place 
of the two first, true molars-
