284 CLATHURELLA. 



Crosse. Subsequently, ascertaining that it is distinct from that 

 species, he named it C. luteofasciata, Reeve from which it is 

 also distinct. Mr. Gillies calls it as above. 



C. FUSCOBALTEATA, Smith. PL 25, fig. 59. 



Yellowish, pale violet or lilac towards the apex, banded with 

 light brown, one band at the top of the whorls darker than the 

 rest ; ribs about sixteen, crossed by fine line ; lip thickened within 

 and exteriorly, thin at the extreme edge, smooth interiorly, sinus 

 sutural, small. Length, 12 mill. 



Japan. 

 C. SUBZONATA, Smith. PL 25, fig. 56. 



Light yellowish brown, more or less distinctly medianly 

 banded, with opaque white lines interrupted by dark brown dots 

 or short lines, sometimes marked with opaque white streaks just 

 beneath the suture, and with a second less apparent transverse 

 band around the lower part of the body-whorl ; ribs sixteen, 

 crossed by spiral lirse ; lip moderately thickened, smooth within, 



with a small sutural sinus. Length, 17 mill. 



Japan. 



C. CANALICULATA, Reeve. PL 17, fig. 9. 



Ovately turreted, suture of the spire channeled, whorls finely 

 latticed with raised striae, sinus large ; whitish. 



Length, 9 mill. 



Hob. unknown. 



A light elegantly formed shell, contracted at the base. 

 C. ROBILLARDI, Barclay. PL 16, fig. 55. 



Shell thin, white, with distant, thin, ridge-like ribs, and distant 

 revolving lirse, more closely striate at the base. 



Length, 1 inch. 



Mauritius. 

 C. BICOLOR, Angas. PL 16, fig. 61. 



Rather solid, light yellowish brown, the sutures, lower half of 

 the body-whorl and interior of aperture reddish chestnut ; whorls 

 very narrowly, obtusely shouldered; longitudinal ribs close, 

 crossed by revolving striae; outer lip thin, denticulated within, 

 strongly varicose externally, sinus rather broad and deep. 



Length, 7-12 mill. 



Port Jackson, Australia. 



It is possible that Drillia vexillum, Reeve, is identical with 

 this species, and if so, that name has priority.
