TiiE Carnivora of the Siwalik and Narbada beds form a sumptuous 

 volume of about 180 pages, illustrated with twenty-one plates and 

 the same number of woodcuts. The memoir begins with the 

 Mustelida?, and gives a statement of the dental characters of the 

 division termed Mustelina?, comprising the weasels, glutton, badger, 

 and their allies. The group is but poorly Te])reseutcd in a fossil 

 state. In India there are species of the genus Mellivora, which has 

 living representatives in India and South .Africa, if, indeed, there be 

 any valid distinction between those ratels. The 3Iellivora sivalensis 

 was referred to Ursitaxus by Falconer and Cautley. It is known 

 chiefly from cranial remains from the valley of the Ganges, and is 

 distinct from the living species. Mellivora punjahiensis is a new 

 species, founded upon a mandible ; it was about the same size as 

 the living and other fossil ratels, but had smaller premolar teeth, 

 whereas in M. sivalensis the third and fourth premolars are large. 

 Another genus, represented by a single species, is indicated by the 

 MelUvorodon palcnndicns. It, too, is described from mandibles. 

 The fragments are very small, but show some interesting characters, 

 differing from Mellivora in features which suggest comparison 

 with the glutton ; and it has the bluntly trenchant talon to the 

 carnassial tooth which is characteristic of gluttons and ratels. We 

 then pass on to the otters. The author discusses the generic dental 

 characters of Ltitra, and enumerates the living siiecies of the Indian 

 region, also the fossil species, which are mostly known from France 

 and Italy. The Indian species are three in number — the Liitra
