Shell sometimes three-eighths of an inch long, and a quarter of 

 an inch broad, but is generally rather smaller ; the rib which 

 attends the margin of the ^^hi^ls is much broader and more 

 elevated than the transverse striee, and is obliquely crenulat- 

 ed ; the lower whirls are greyish brown, sometimes spotted 

 with white, and the summit is almost constantly of a fine 

 deep crimson colour.

This shell much resembles T. minutus, and is of the same size, 

 but rather narrower in proportion to its length, and differs 

 in having the transverse strize much stronger, and the rib at 

 the margins of the whirls more elevated, and so distinctly 

 striated crossways as to have a beaded appearance ; it is of a 

 rose-colour, more or less marked with white longitudinal 

 strij)es, and the summit is not of a brighter red than the 

 other whirls. 



CONULUS. 93. Shell conical, smooth, with a strong 

 rib on the margin of the whirls.
