Group of G. lachryma 



In the présent state of our knowledge of this group it is 

 impossible to say whether we are dealing, as seems highly 

 probable, wilh variations of a single type, or whether the 

 group contains separable species: in the latter caseit will 

 probably be necessary tostill further subdivide the group. 

 Gonchologically the group of C. lachryma appears to be 

 closely relaled to Mitrolumna, Bucq., Dautz et Dollf., and 

 to the groups of C. Peasci, C. Dautzenbergi and C. dormilor; 

 but failing any knowledge of the animal or its anatomy the 

 correctness of the référence of thèse groups to the Colum- 

 hellidœ must remain somewhat doubtful, 



Group of C. dormitor. 



C. Fisclieri, Herv. This appears to be thesame form as 

 that described by Pease(l) âs Conus fusiformis; but this 

 latter name being pre-occupied, Hervier's name may well 

 be retained for the Polynesian member of theC. dormitor 

 group. This species may prove not to be separable from the 

 Galiforniau species described by Carpenter (2) as Mitro- 

 morpha filosa. Hervier contrasts C. Fischeri with a species 

 of Conus also met with at Lifu and which he identifies as 

 C. atramentosiis Rve. ; but, Reeve's species, the type- 

 specimen of which is in the British Muséum, is itself a 

 member of the ColumbeUa dormitor group. 



In conclusion, it is to be hoped that those who hâve the 

 opportunity to collect in the wouderfully prolific Pacific 

 regionwillnotconfinetheiraltentionmerely todead,beach- 

 worn material ; but, that they will explore the haunts of 

 the living Molluscs, observiug their habits during life and
