156 CANTHARUS. 



nella, the former as synonymous with G. 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 G. rubi- 

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



chestnut-brown, with a white band. 



South Africa. 



C. LTMBATUS, Phil. PI. 73, fig. 251. 



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

 volving stride 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, Bunker. PI. 13, fig. 258. 



Yellowish brown, generally with two white revolving bands on 



the body-whorl. Length, 15 mill. 



Java. 



Looks very much like a minute edition of fumosus var, rubi- 

 ginosus. 



C. BOLIVIANUS, Souleyet. PI. 13, fig. 259. 



Yellowish brown, not banded. Length, 1 mill. 



Cobija ; Bolivia. 

 Evidently allied to the above. 



C. CAPENSTS, Bunker. PI. 13, fig. 200. 



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



Cape of Good Hope. 



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 pro veto be synonymous 

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

 represents Pisania lacertina, Gould 



C. RUBENS, Kiister. PI. 13, fig. 261. 



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



longitudinal and revolving ribs. Length, 22 mill. 



R<-d Sea. 



The smaller size, and more numerous ribs are relied upon as 

 distinguishing features from G. fumosus var. rubiginosus^ but I 

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