1889.] DIFFERENT SPECIES OF OTTER. 195 



(4) Lutra swinhoei, Gray, P. Z. S. 1867, p. 182 ; Cat. Cam. 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 Gawivang 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 L. cinerea, which, alone of all Otters, is, 

 as Dr. Gray says of this skull, " characterized by the small sire of 

 the upper cutting-teeth, the series forming only a width of 4| lines ; 

 while the series of most other Indian Otters occupy 6 lines, or 

 sometimes more."
