DESCRIPTION OF PLATES. 133 
large, and were evidently of great strength and massiveness. All trace 
of the first molar, which is very small and deciduous, has disappeared. 
The second molar has two fangs, and is encircled by a rugged basal 
ridge. The carnassier is very remarkable, and presents the prominent 
feature of the genus. It is nearly square, instead of being triangular, 
as in both Lutra and Enhydra; and instead of the cusps and trenchant 
ridges of Lutra, or the flattened inequalities of Enhydra, the coronal 
lobes are developed into cervical mammille, somewhat like those of the 
Mastodon. A more detailed description of this tooth will be found in 
Dr. Falconer’s memoir on ‘Enhydriodon.’ Behind the carnassier, 
the tubercular is seen 7n situ.—B.M. No. 37,155. 
Figs. 6,6 a, and 6b.—Enhydriodon ferox. Fine specimen of ante- 
rior portion of cranium of a young and probably female individual. 
Shows three incisors on either side, the two inner of which are very 
much compressed laterally, so that their antero-posterior diameter is 
three times that of their width. The outer incisors are remarkably 
large, as are also the canines. The left canine has dropped out, leaving 
a large oval alveolus; the right canine is seen in section. Behind the 
canine, on either side, is an extremely small empty alveolus of the first 
deciduous molar. Then comes the bicuspid second molar, the peculiar, 
square, mammillated carnassier, and the tubercular.—B.M. No. 87,154.
