Stat. 51. Madura-bay. 69 — 91 M. Fine grey sand, coarse sand with shells and stones. 2 Spec. 



Stat. 95. 5°43'.5 N., ii9°4o'E. Sulu-archipelago. 522 M. Stony bottom, i Spec. 



The specimens are not quite typical, they are nearly colourless, which may scarcely be 

 ascribed in every specimen, to their being bleached, the spiral striae are very faint, except near 

 the base and just below the suture. The young specimen from Stat. 95 is a dead shell and will 

 not have lived at this exceptional depth -, it has the spiral striae more conspicuous.

This species varies in size, the specimens from Stat. 5 1 being only about 5 Mill, in 

 length and relatively narrow, the largest from Stat. 193, 7 Mill, in length; in the bands, the 

 upper one disappearing in a few instances, in number of ribs, which in one of the specimens 

 from Stat. 5 1 are much less numerous on upper whorls, still scarce on the specimens from 

 Stat. 47 and abnormally thick, varix-like and few in number on that from Stat. 60, which I 

 consider to be a monstrosity ; as the sculpture of last whorl agrees fairly well with more typical 

 specimens, I think it not advisable to give it even a varietal name, as there is but one such 

 a specimen.
