Mr. Cuming collected specimens at rocky places from three to six 

 fathoms deep. The outer lip is more expanded, and the knotted 

 brown bands are narrower and more numerous than in R. argus. 



2. Ranella cruentata, Conch. Illustr., f. 5, 5*. R. testd sub- 

 quadratd, rugulosd albd vcl pallide fulvd, rubro-maculatd, inter 

 varices ad angulum anfractuum tuberculis magnis tribus, in medio 

 tribus minoribus ; varicibus elevatis, utrinque foveolatis ; aper- 

 turd paululum angustatd, extremitatibus validissime canaliferis ; 

 labio interno decumbente, dentibus acutis instructo, maculis san- 

 guinis 5 ad 6 in medio picto ; labio externo complanato, subdigi- 

 tato, intus dentibus validis instructo. 



Long. 1-50; lat. 1*20 poll. 



Hab. ad insulam Ticao, Philippinarum. H. Cuming legit. 



Found on coral reefs. This species is remarkable for the well- 

 defined spots of blood-red colour by which that part of the inner 

 lip which rests upon the body-whorl is ornamented. A darker va- 

 riety occurs, in which the spots are of a strong brown colour. 



3. Ranella nana, Conch. Illustr., f. 6. R. testd elongato-ovali, 

 leevi, inter varices nebuloso-purpured, in medio anfractu fascid 

 albd cinctd, ad angulum anfractuum tuberculis acutis quatuor, 

 anterius tuberculis parvis ; varicibus prominentibus, antice laque- 

 atis, postice canalem exhibentibus ; aperturd ovali, ad extremita- 

 tes validissime canaliferd ; labio interno granoso ; labio externo 

 valde denticulato. 



Long. 1*80; lat. 1*05 poll. 



Hab. ad insulam Panama, Philippinarum. H. Cuming legit. 



Found in coarse sand at seven fathoms. 



4. Ranella albo-fasciata, Conch. Illustr., f. 14. R. testd ovali, 

 subcompressd, granulosd, fusco-purpured, fascid albd in medio 

 anfractu cinctd, lineis moniliformibus numerosis et ad angulum 6 

 ad 7 tuberculis cinctd ; varicibus granuloso-tuberculiferis ; aper- 

 turd ovali, ad extremitates validissime canaliferd ; labio interno 

 granoso ; labio externo valde denticulato. 



Long. 1*80; lat. 1 '20 poll. 



Hab. ad insulam Panama, Philippinarum. 



Much broader and more completely granulated than the former, 

 •which is nearly all over smooth. In this respect our shell resembles 

 R. granulata, Lam., but it is neither so oval nor so compressed, the 

 varices are more strongly marked, and the posterior canal is more 

 perfect. 



Found in coarse sand at 10 fathoms. 



5. Ranella rhodostoma, Conch. Illustr., f. 10. R. testd sub- 

 quadratd, rugulosd, granulatd, pallide fulvd, rufo-punctatd et 

 maculatd, inter varices tuberculis prominentibus tribus ad angulum, 

 tribus in medio anfractu ; aperturd roseo-purpured, paululum an- 

 gustatd, ad extremitates valde canaliferd ; labio interno granu- 

 loso prope canales transverse dentato, labio externo sub-expanso, 

 undulato, intus dentato ; varicibus granoso-tuberculatis, validis, 

 utrinque foveolatis.
