286 CLATHURELLA. 



C. GRACILISPIRA, E. A Smith. PL IT, fig. 94. 



Light yellowish brown, faintly banded with chestnut between 

 the ribs on the upper part of the whorls, and stained with chestnut 

 below the middle of the body-whorl. Length, 15 mill. 



Japan. 



More slender, the whorls more convex, the extremities more 

 lengthened and attenuated than C. bicolor, Angas, 



C. LETOURNEUXIANA, Crosse. PI. IT, figs. 8T, 86 ; PI. 34, fig. 99. 

 Yellowish brown, or light reddish brown. Length, 12 mill. 



New South Wales; Tasmania. 



Yar. LALLEMANTIANA, Crosse. PI. IT, fig. 86. 



Two of the revolving lines more prominent, ridge-like. 



C. incrusta, Tenison-Woods (PI. 34, fig. 99), is a smaller shell, 

 T mill., with two of the revolving striae more prominent (on the 

 body-whorl 8-9), slightly keel-like. I figure it from a specimen 

 sent to me by Mr. C. E. Beddome, of Tasmania. I believe it to 

 be a synonym of C. Letourneuxiana, var., one of my specimens 

 of the latter exhibiting a transition from the normal type with 

 equal revolving sculpture to the form with two more prominent 

 lines. 

 C. PYRAMIDULA, Reeve. PL IT, fig. 20.

 whorl somewhat truncated at the base; yellowish brown, or 

 yellowish white. Length 11 mill.

Yellowish brown ; closely sculptured by longitudinal numerous 

 ribs and spiral striae ; a very slight concave constriction below 

 the sutures ; aperture rather small, light brown within, outer lip 



thin. Length, IT mill.

C. MUTICA, Hinds. PL 34, fig. 98.

 tudinal chestnut strigatidns and a median white band, chestnut 

 at the base. Length, 15 mill.
