Plate P. 

 Fossil Otters, from the Sewalik hills. 



Figs. 1, la, lb, and 1 c. — Lutra Palmndica (Falc. and Caut.). 

 Beautiful specimen of cranium with alveolar ridges very perfect. The 

 zygomatic arches are absent. Shows the alveoli of three incisors on 

 either side, the outer one being slightly larger than the two inner ones. 

 Outside the three incisors is the alveolus of a large canine, followed by 

 the alveoli of four small molars, and last of all by the carnassier and 

 tubercular, the latter greatly developed. — B.M. No. 37,151. 



Figs. 2 and 2 a. — Lutra Palmndica. Beautiful specimen of lower 

 jaw, left side, including ascending ramus. Shows a portion of canine 

 and of three small molars, the crowns of which aie broken off. Behind 

 there is a large carnassier, very perfect ; and last of all is the alveolus 

 of the tubercular, which is small in comparison to that of the upper 

 jaw.— B.M. No. 37,152. 



Figs. 3 and 3 a. — Lutra Indica. Two views of skull, upper and 

 lateral, of existing Indian Otter.

 otter from the Sewalik hills. Three views of cranium, probably female, 

 much mutilated. Shows on right side the posterior of the two false 

 molars, the carnassier and the tubercular. The anterior premolar, 

 which is deciduous, is wanting. The remarkably square form of the 

 carnassier is well seen. — B.M. No. 37,153. 



Figs. 5 and 5 a. — Enlvjdriodon ferox. Fine specimen of anterior 

 portion of cranium of an old individual, with very perfect alveolar 

 ridges. Shows on either side the alveolus of a large outer incisor, 

 which evidently served as a subsidiary canine. The middle incisors 

 are not only wanting, but the alveoli are completely filled up and 

 obliterated. The canines, which are broken across, are seen to be very 



1 Subsequently designated Enhydriodon Sivalensis.
