Mr. Hodgson states, “ the Otters, in the upper region of the Hi- 
malaya, are represented by the small golden and brown species L. 
aurobrunnea, in the central by ZL. monticola and L. indigitata, and 
in the lower by the large Chinese species L. sinensis” (Proc. Zool. 
Soc. 1855, p. 126). 
d. The under surface of the feet, between the finger-pads and palms, 
sprinkled with scattered soft hairs; the inner part of the under 
surface of the two inner hind toes with a band of close, short, 
soft hairs ; the muzzle transverse and bald. 
14. HypROGALE. 
Like Lutra externally ; but the feet large, elongate, very broadly 
webbed ; the toes, especially of the hinder feet, long ; the pads of the 
toes and palms are less developed and separated from each other by 
a greater distance ; the under surface of the feet sprinkled with scat- 
tered soft hairs, and the edges of the two inner hind toes have a band 
of close, short, soft hairs. The skull elongate; the nose very short ; 
the forehead narrow ; the orbit scarcely defined behind, without any 
indication of a tubercle on either the upper or lower edge. The 
flesh-tooth with the internal lobe shorter than the outer portion of 
the tooth; the tubercular grinder rhombic, wider than long; the 
hinder portion of the palate rather short, with an arched posterior 
opening.
