156 GANTHARUS. 



nella, the former as synonymous with C. porcata, the latter as a 

 distinct species; but the want of a superior depression on the 

 whorls and the possession of tubercles near the base of the colu- 

 mella show that Krauss was right in comparing it with C. rubi- 

 ginosus, although it may not be identical with that species. It is 



chestnut-brown, with a white band.

C. LIMBATUS, Phil. PL 73, fig. 257. 



White, marbled with orange. Longitudinal ribs fourteen, re- 

 volving striae eight ; lip with an external varix. Length, 10 mill. 



West Indies. 



I know nothing of this minute species ; it is a very doubtful 

 one. 



C. EXTENSUS, Dunker. PI. 73, fig. 258. 



Yellowish brown, generally with two white revolving bands on 

 the body-whorl. Length, 15 mill. 



Looks very much like a minute edition of fiunoxux var. rubi- 

 ginosus. 



C. BOLIVIANUS, Souleyet. PI. 73, fig. 259. 



Yellowish brown, not banded. Length, 7 mill.

 Evidently allied to the above. 



C. CAPENSIS, Dunker. PI. 73, fig. 200. 



Dirty yellow, variegated with brown. Length, 22 mill.

Among eight specimens, two had white bands. The specimen 

 figured is evidently not adult. I cannot, for want of material, 

 decide upon its position, but think it will prove to be .synonymous 

 with C.fiimosux. Kobelt's figure of this species is incorrect, and 

 represents Ptxania lacertina, Gould 



C. RUBENS, Kiister. PL 73, fig. 261. 



Dull orange-brown, white within. Surface cancellated by close 

 longitudinal and revolving ribs. Length, 22 mill. 



Tin* smaller size, and more numerous ribs are relied upon as 

 distinguishing features from C.fumoxns var. rubiginotsus, but I 

 think it may prove to be a stunted variety of that species. Prof.
