CANTHARIDUS. 145 



C. TORRESI E. A. Smith. PL 46, fig. 62. 



Shell sharply conical, subperforated or with the perforation con- 

 cealed, greenish (sometimes pinkish red), with oblique white nar- 

 row stripes and darker green or rosy black spotting at the base of 

 the whorls and upon the angle of the last. Volutions about 8, flat, 

 margined at the lower part with two rows of closely-packed 

 granules, rather more prominent than five others above. Between 

 these, in well-preserved specimens, very fine lira (one in each inter- 

 stice) and oblique lines of growth are discernable. Last whorl 

 rather acutely angled at the periphery, beneath with about 9 con- 

 centric rows of granules alternating with others very much finer 

 having smaller subobsolete tubercles. The aperture is obliquely 

 subquadrate ; columella a little arcuate at the upper part, white, re- 

 flexed over the white umbilical region and subtruncate anteriorly. 



Alt. 12, diam. 9J ; alt. 13, diam. 12 mill. (Smith.)

There are two varieties of this pretty species, which may be 

 termed the green and pink. In the green variety the base in three 

 out of the four examples is somewhat pinkish, radiately streaked 

 with white, whilst in the fourth specimen it is green with irregular 

 streaks and has a more tessellated aspect. The perforation is small, 

 and may either be concealed by a thin callosity or remain open. 

 This is a smaller species than T. fragum Phil., has more numerous 

 granules (of which there are five instead of four rows besides the 

 basal girdle), and intervening fine lira are generally to be met with 

 on the spire which are wanting in Philippi's shell. I should also 

 observe that the columella of T. fragun, judging from the figure, is 

 less incurved than in this form. (Smith.)

Evidently closely allied to C. pyrgos Phil.

Shell very narrowly perforate, conical, rather thick; whorls 7 to 

 8, planulate, the first eroded, the succeeding whitish-ashen, radiated 

 with narrow, close and flexuose blackish and violaceous lines ; 

 spirally cingulate ; line 6 on penultimate whorl ; last whorl sub- 

 angular, a little depressed above, dilated in the middle ; base con-
