These specimens are small and those from Stat. 37 and 53 are moreover bleached, conse- 

 quently I cannot make out to which variety they belong ; the majority of specimens belongs to : 



var. tessellata Philippi.

As the views of authors about N. marochiensis, its synonyms and varieties are very 

 different, I have applied the name given by Philippi to a shell with characteristic colour-pattern, 

 some specimens are partly of a brownish ground-colour.

Shell conically globose, thin, smooth, shining, with traces of a thin epidermis towards the 

 aperture; whorls 5 1 /.-,, convex. The nuclear and part of subsequent whorls are nearly smooth, 

 but have a few radiating striae and the suture is bordered by a spiral ridge. The last 2 1 /, 

 whorls are separated by a deep suture, with radiating striae, gathered puckerings below it. 

 Moreover the shell is covered with very fine growth-striae and a few scattered spirals, which 

 are only visible under a strong lens. Colour very light lilac, with a narrow white zone at the 

 suture, and a broader one round the umbilicus; the lilac zone of the shell has very faint rufous- 

 brown streaks, which are more or less waved, forming at the shoulder of last whorl, a row oi 

 arrowdieaded spots and a row of squarely-oblong blotches, just above the umbilical white zone. 

 Aperture oblong-ovate, rather angular at the upper corner; right margin thin, curved, columellar 

 margin nearly straight, but slightly concave, its upper part reflected on the body whorl, tongue- 

 shaped just above the umbilicus, of which only a small, deep pit of the upper part remains, 

 the umbilicus being nearly quite filled by a white, porcellaneous funiculum, with only a groove 

 at its left side, originating from the umbilical pit, becoming shallow towards the base. Oper- 

 culum calcareous, for a large part smooth and shining, near the nuclear part thickened by a 

 dull layer, bordered at the left by a comma-shaped rim ; right margin bordered by 3 raised 

 rims, of which the outermost is narrow and not strongly developed, especially towards the base 

 of the aperture; the median rim is rather narrow, much raised, bordered externally by a 

 shallow, internally by a deeper groove ; internal rim the broadest, separated from the rest of 

 the operculum by a, deeply incised groove.
