Of the species belonging to allied genera, Hemigale hardiLii.ckii has 

 broad transverse coloured bands on the back. Nandinia binotuta 

 may be recognized by its back and sides being spotted with large 

 dark spots, by a pale spot on eacli side of the withers, and a sub- 

 annulate tail ; Arclcgale trivirgata and A. leucotis by having three 



1 This key will, in most cases, serve to identify specimens of Paradoxiirus, 

 but, I fear, not always by means of the external characters. I have, since this 

 paper was in type seen three specimens of P. hcrmaplirodUus, obtained by Dr. 

 J. Anderson in the Mergui Archipelago, Tenasserim. One of those is uniformly 

 dark brown, almost black, and resembles in colour some forms of Arcfoga.'e 

 leucotis, having none of the markings of P. harmaphroditus. The other two 

 are dark brown, with the vibrissa; in part white, and are externally only distiii- 

 guisliable by size from P. Icucomystax. The skull, however, in each case is un- 

 mi.stakably that of P. hermaphroditus.
