CLATHURELLA. 293 



granules, often upon every alternate rib, interrupted by a central 

 white space, and again painted towards the base. 



Length, 8-10 mill. 



New Ireland, Upolu, New Caledonia. 



Reeve's figure (fig. 18) is a very poor one ; that of Hinds (PI. 

 32, fig. 40) is better, but neither that, nor the figure of one of the 

 synonyms, C. apicalis, Montrouzier (PI. 22, fig. 64), exhibits per- 

 fectly the usual arrangement of the coloring ; sometimes this 

 coloring is broken up and more or less dispersed over the sur- 

 face, and then there is considerable resemblance to the preceding 

 species. CL picta, Thinker (unfigured), is probably identical, 

 and CL maculosa, Pease (PI. 19, fig. 70), appears to be a small 

 variety. 

 C. PUNCTTFERA, Garrett. PI. 19, fig. 74. 



Ribs small, narrower than their interstices, ten to eleven on 

 the body-whorl, crossed by smaller transverse ridges, the granules 

 of intersection light brown, the rest of the shell cinereous; 

 sinus rather large, semicircular, lip six-toothed within. 



Length, 5 mill. 



Society, Samoa and Viti Islands. 



This species is allied to the preceding ; the spots on the granu- 

 lated ribs are not shown on the figure in which the ribs also 

 are too narrow. 



C. PERPLEXA, Nevill. PI. 19, fig/65. 



Uniform ash-color, a shade or two darker in the interstices of 

 the ribs and near the apex ; columella, outer margin of the lip 

 and interior of the aperture bright chestnut-brown ; outer lip 

 very sharp, irregularly undulating, obsoletely granulated just 

 within the aperture. Length, 6 mill. 



Bombay, Ceylon. 

 C. SINGULARIS, Nevill. PI. 19, fig. 61. 



Faintly and obtusely ribbed, crossed by distant raised lines; 

 whorls obtusely angulated at the periphery ; white, in the centre 

 of the ribs on the last whorl ornamented with obsolete brown 

 spots. Length, 8*5 mill. 



Andaman Islands. 

 C. MASONI, Nevill. PL 19, fig. 60. 



Sharply shouldered, white, outer lip granular within. 

 Length, 4 mill. 



Andaman Islands.
