ADDENDA TO SYNOPSIS OF SIWALIK & NARBADA MAMMALIA. 
General. — Since the publication of the Synopsis of Siwalik and Narbada Mam- 
malia in the third part of the present volume several new upper Siwalik species 
have been added to the list, and some emendations made in regard to certain genera 
and species ; while there is one provisional new species to be added. All these addi- 
tions are noticed in the sequel ; the genera being taken in the same order as in the 
Synopsis. It may be premised that the division of the Artio- 
dactyla into the sections Ruminantia and Suina, and of the 
latter into the subsections Selenodontia and Bunodontia has 
been abandoned.^ 
Mustela, sp. — This form {infra, p. 125) is determined from 
Fig. 1. Mustela, sp Frag- ^ fragment of the left ramus of the mandible (woodcut fig. 1), 
thrm°andibief*^from''ti^^ wliicli is described and figured on page 177 of part I. of the 
Mus^eum “Cat. Foss. Mamm. Brit. Mus.” It indicates a species as 
large as M. flavigida. 
Nesokia, sp. — The specimen alluded to in the synopsis {infra, p. 126) as Mus. 
(?), sp. is referred in the “ Cat. Foss. Mamm. Brit. Mus.’ part I. p. 226 to Nesokia; 
it presents no characters by which it can be distinguished from N. hardwicJcei, Grray. 
Lepus, sp. —The fragment of the mandible of a Lepus mentioned in the 
synopsis {infra, p. 126) is described in the “ Cat. Foss. Mamm. Brit. Mus.” pt. I. 
p. 262 . 
Bubalus buffelus. — The so-called B. palceindicus (which occurs only in the 
topmost Siwaliks and the Narbadas) is referred to a variety of this species {vide 
“ Cat. Foss. Mamm. Brit. Mus.” pt. II. p. 28). ^ 
Hemibos. — This genus (including three species) is now merged in Bubalus {vide 
“ Cat. Foss. Mamm. Brit. Mus.” pt. II. p. 28). 
Strepsiceros (?) falconeri, Lgd .^ — This is a new species founded on part of a 
cranium from Perim Island {vide “Cat. Foss. Mamm. Brit. Mus.” pt. II. p. 47). 
Hippotragus sivalensis, L?/d.— The so-called Antilope sivalensis {vide infra, p. 
128) is referred to Hippotragus {vide “ Cat. Foss. Mamm. Brit. Mus.” pt. II. p. 49). 
Cobus. — Two species have been referred to this genus, viz. the so-called Antilope
