STMPULUM. 13 



T. OEMMATUS, Reeve. PI. 7, figs. 41-44. 



Whitish to orange-yellow. Revolving ribs fewer in number 

 than in T. rubecula, with three revolving strise between each rib 

 of which the middle one is largest ; frequently laticed by longi- 

 tudinal ribs, and sometimes developing two or three nodules 

 between the varices. Length, 1 to 1-5 inches. 



Philippines to Sandwich Islands; Paumotus. 



More graceful in form, with more rapidly accuminated spire 

 and longer canal, and smaller than T. rubecula ; to which 5 

 nevertheless, it is closely allied. T. mundum Gould, (figs. 43, 

 44), appears to be the same species. 

 T. FICOIDES, Reeve. PI. 7, fig. 46. 



Fig-shaped ; yellowish, the lip and columella orange color. 



Length, 2 inches. 



West Africa. 

 T. OHLOROSTOMI s, Lam. PI. T, figs. 47,48. 



White, more or less tesselated with red or chocolate spots, 

 the revolving, incised lines usually colored ; aperture deep 

 orange within. Length, 1*5 to 3 inches. 



Red Sea ; Me of Bourbon ; New Caledonia ; Philippines ; 



Central Pacific; Sandwich Islands; West Indies. 



T. CORHI.MJATUS, Lam. PL 8, tig. 49. 



Whitish, more or less stained and marked with brown; 

 epidermis brown, pilose. Length, 2*5 to 3'5 inches. 



Mediterranean; Atlantic coasts of France, Portugal and Spain. 

 Var. KREBSIT, Morch. PL 8. fig. 50. 



Spire shorter, nodules between the varices stronger. 



St. Thomas, St. Croix, W. I. 



Described as a distinct species but the characters by which 

 Morch distinguishes it are common to the type form except the 

 shorter spire and more rugose longitudinal ribs. Probably not 

 perfectly acclimated, and depauperate in consequence. 



T. BECCARII, Tapparone-Canefri. PL 7, fig. 45. 



Light yellowish; aperture orange color. Length, 1*75 inches. 



Massaua; Red Sea. 



A single specimen only obtained. Its very narrow form will 

 distinguish it at once from the nearly related species.
