Jee Nai) 12. 
Fossil Otters, from the Sewalik hills. 
Figs. 1, la, 16, and 1e.—Lutra Paleindica (Fale. 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 Jarger 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. 87,151, 
Figs. 2 and 2 a.—Lutra Paleindica. Beautiful specimen of lower 
jaw, left side, including ascending rainus. Shows a portion of canine 
and of three small molars, the crowns of which are 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 8a.—Lutra Indica. Two views of skull, upper and 
lateral, of existing Indian Otter. 
Figs. 4, 4a, and 4b6.—Enhydriodon ferox.! A new fossil genus of 
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. 87,153. 
Figs. 5 and 5 a.—Enhydriodon 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 
! Subsequently designated Exhydriodon Sivalensis.
