TURBO. 203 



T. PULCHER Reeve, 1842. PL 46, fig. 7. 



Shell ovate-conic, solid, subimperforate, yellowish fawn color, 

 greenish toward the apex, painted with short blackish waved longi- 

 tudinal lines ; whorls 6-7, not very convex, lirate with numerous 

 irregular ribs, alternately large and small, the interstices scaly ; 

 aperture subrotund, pearly white Avithin, peristome crenulate ; col- 

 umella slightly thickened and somewhat produced at base. Alt. 60 

 mill. N. Andralia. 



Operculum, according to Sowerby, like that of T. sarmaticus. 

 This however is highly improbable. I expect to find it like that of 

 T. ticaonkus and other allied species of Senedns. 



T. MOLuccENsrs Phil, 1846. PI. 44, fig. 76. 



Shell globose-conoid, umbilicate, green, rufous marbled ; whorls 

 rounded, the upper ones reddish, spirally lirate, the line unequal, 

 slightly elevated, separated by narrow obsoletely crenulated inter- 

 stices ; aperture subcircular, lip within green-margined, obsoletely 

 crenulated. Ins. Amboina. 



Philippi's description and figure are given. 



T. CASTANEUS Gmel., 1788. PI. 45, figs. 88-90. 



Shell ovate-conic, imperforate, solid, orange-colored, brown or 

 gray, sometimes banded, flammulate, or maculated with white ; spire 

 conic, acute; suture subcanaliculate; whorls 5-6, convex, ornamen- 

 ted with numerous unequal spiral granose, spinose or squamose lira?, 

 of which the subsutural and three or four submedian are more 

 prominent; aperture white, subcircular, subangular above; peristome 

 slightly produced below; columella wath a heavy white callus. 



Alt. 30, diam. 25 mill. 



West Indies; coast of the Gulf of Mexico. 



Operculum (PI. 59, fig. 8,) castaneous within, with four rapidly 

 increasing whorls, nucleus one-third the distance across the face; 

 outside convex, nearly smooth, white, or stained with brown and 

 green around the middle. 



T. n-enulatus Gmel., T. virens Anton, and T. hippocastanum Lam. 

 are synonymous. 



The typical form is very sharply sculptured, the principal lirse 

 bearing vaulted scales. In crenulatus Gmel. the ribs bear less con- 

 spicuous tubercles. An abundant and variable species.
