1889.] DIFFERENT SPECIES OF OTTER. 195 
(4) Lutra swinhoei, Gray, P. Z.S. 1867, p. 182; Cat. Carn. B. M. 
p. 105 (1869). 
This species was founded by Dr. Gray on a fragmentary skull 
sent by Mr. Robert Swinhoe from China. The locality was origi- 
nally given as Formosa, but Mr. Swinhoe afterwards stated’ that the 
Otter was obtained at Gawkang Island, near Amoy, and gave, at the 
same time, some observations on its habits. 
The typical skull, as suggested by Dr. Anderson, proves, on com- 
parison, to be referable to Z. cinerea, which, alone of all Otters, is, 
as Dr. Gray says of this skull, “characterized by the small size of 
the upper cutting-teeth, the series forming only a width of 42 lines ; 
while the series of most other Indian Otters occupy 6 lines, or 
sometimes more.”
