C. joue/kgroup. Reeve's species is of a very difïerent cha- 

 racter indeed. 



Group of C. jaspidea. 



As remarked above, C jaspidea, Sby, C. piicaria, Montr. 

 and C. valga, Gld. should be considered together with 

 C. Marquesa, Gask. to which they are certainly very closely 

 related. 



Group of C. lifouana. 



I see no valid reason for separating from the very 

 variable C. striatula, Dkr. those forms which Hervier has 

 distinguished as C. lifouana, Herv. and C. isomella. Duel. ; 

 and uone of the recorded variations appear to be other 

 than merely individual ones, and are therefore not worthy 

 of spécial names. Duclos' figure, by the way, is not in my 

 opinion a représentation of the Pacific form recorded by 

 Hervier, but is intended for the West Indian C. pulcheila 

 (Bl.) 



Group of C. nanisca 



The forms associa! ed by Hervier with Ç. nanisca do not 

 appear to me to be at ail closely related to this species, 

 which in its conchological characters approximates to the 

 groups of C. lachryma and C. Daulzcnhcrgi. 



C. nanisca, Eerw . (= C. Peasei, Mrls. etLangk.). Itis this 

 form which was described by Pease (1) from the Sandwich 

 Is. as Cythara varia, and which was renamed by Martens 

 and Langkavel (2) Columhella Peasei. The species recorded 

 by Hervier as C. Peasei, and which I am proposing to name 

 C. Henrieri, isa very différent form. 



C. ocellatula, Herv. This judging from the material at my
