2 E. C. Joshua : 



the wheel papillae and aggregations are not c(Mi8tantly met with, 

 and that in ninnerous individuals the distril)uti(iii of the wheels 

 conld only be described as scattered everywhere, thus coni])ining in 

 one species the characters of two genera. So gi'eat an authority 

 as Dendy will have neither of these genei-a, and adhei-es to tlie 

 original genus Chiridota for the reception of all these wheel-bear- 

 ing forms. Personally, I think that the genus Cliiridofa nuiy be 

 usefully sepai-ated from the sigmoid bearing genera on account of 

 its members exhibiting bracket shaped ossicles ; there would appear 

 to be no species having an ossicle which could "be described as 

 intermediate in form between a sigma and a bracket. 



Verrill's genus Leptoxi/napta is used for the species doJahrifrra 

 iStimpson, Clark (3) having definitely pointed out the propriety 

 of this course. 



The following is a list of the species dealt with : — ■ 



Stlvliopiix nioUis (Hutton).

GENUS STICHOPUS. 



Sticiiopus mollis (Hutton). 



For syiiouyniy see 



1907. Sticiiopus mollis, Dendy and IJindU- (To; and 

 1887 Holothuria victoriae. Bell (1); 

 191.3. Sticiiopus mollis, Erwo Willy (S). 

 After Trading Bell's act'ount of his Il.,lotliinia \ictori;te. and 

 examining tlie hgures he gives of its spicules. I havr no hesita- 

 tion in synonymising it with Hutton 's species.
