This species bears some resemblance to the Bornean 

 C. tomentosa, but it is, however, rather more globular, lias a 

 periphcrial reddish line, a thicker lip, and the aperture is of a 

 different shape.

The specimens from this locality are rather small, the 

 largest having a diameter of 21 millim. only. They are orna- 

 mented with a single narrow deep brown line revolving up 

 the centre of the whorls, and two others of a much paler tint 

 and not so well defined, one above the keel and the other a 

 little below the suture. The central basal zone is also 

 narrower than that depicted by Pfeiffer (fig. 9) or by Reeve 

 (fig. 129 i).

Of thirty-four specimens collected by ^Ir. Everett only five 

 belong to the banded variety. Besides the lines of growth, 

 in some examples some very faint spiral strije are more or 

 less discernible under a lens, especially upon the base of the 

 last whorl towards the umbilical region. C. viac^tunciuiisj
