Both specimens are in very jxjor condition. Mr. Melvill who has compared them, says 

 they are what has been till recently considered as C. aiomella Duel., hut that this species has 

 been much split up, and now is considered as belonging- typically to the new world only. Under 

 these circumstances I have left them with doubt to the species of Duclos. They are too bad 

 for description.

Stat. 144. North of Salomakiee-(Damar)-island. 45 M. Coralbottom and Lithothamnion. 3 Spec. 



Shell elongately-oval, with rather acute spire, thick, black brown (if dry greyish, perhaps 

 by the action of alcohol) with white upper whorls and base, a few white spots on the whorls 

 about the periphery and a row of white quadrangular blotches at the upper margin of white base. 

 Whorls about 8, of which nearly 2 smooth ones form the nucleus, subsequent whorls only very 

 slightly convex, separated by a rather conspicuous suture, which is however not very distinct 

 by the spiral grooves, with which the whole shell is encircled; these grooves are rather deep, 

 the subsutural and median one of last whorl however less so, the lirae are granose on 2 or 3 

 postnuclear whorls, lower on they are only closely punctured, the lirae remaining smooth, but 

 for fine growth striae. Aperture oblong, narrow; peristome thin, with only traces of a varix, 

 internally with very faint, irregular wrinkles; columellar margin straight, smooth above, slightly 

 plicate below by the basal grooves. 



Alt. 9, lat. 3^4 ; apert. alt. 4Y3, lat. i Mill. 



This species was very puzzling and it is not without doubt that I have located it in
