TURBO. 193 



T. CEPOIDES E. A. Smith, 1880. PI. 44, fig. 7-s. 



Shell ovate-conic, narrowly but profoundly perforate, pale brown, 

 strigate with green variegated with white ; whorls 7, very convex, 

 slightly compressed or sub-excavated above, with conspicuous irreg- 

 ular sub-lamellose incremental striae and inconspicuous spiral lines 

 and sulci above; aperture almost circular, slightly shorter than the 

 spire, inside pale salmon, pearly. Alt. 80, diam. 70 mill. 



Habitat unknown. 



This species seems to be most nearly allied to T. imperialis and 

 T. jourdani. Smith compares it to T. magnificus Jonas, and says 

 that it is distinguished from that form by the presence of a deep 

 perforation, the narrow sulcations revolving around the upper part 

 of the whorls, and by the coloration. 



T. REGENFUSSI Desh., 1843. PI. 48, fig. 40. 



Shell ovate-conic, thick, imperforate, whorls 5-6, smooth, convex, 

 the last large, dilated, ventricose, angulate above, with a revolving- 

 series of more or less prominent tubercles, below rounded ; aperture 

 circular, inside pearly; peristome simple, posterior angle with a 

 thick callus, columella arcuate, not produced at base ; color vivid 

 green, variegated with spiral series of square alternating white and 

 deep chestnut maculations. Alt. 84, diam. 80 mill. 



Indian Ocean. 



Operculum as in T. imperialis, reddish and granulose without. 



I am not at all certain that the figures cited by Deshayes do not 

 represent a form of T. marmoratus ; they are more produced at the 

 base than the figure given by Fischer (and which I have copied) 

 indicates. It may prove to be a variety of T. marmoratus. 



T. PETHOLATUS Linn., 1758. PI. 40, ng. 14. 



Shell imperforate, solid, polished, shining, rich brown, variously 

 ornamented with dark bands interrupted with white blotches and 

 narrow stripes; whorls 5, flattened beneath the suture, sometimes 

 carinated above ; aperture about half the length of the shell, circular, 

 pearly within ; peristorne and columella tinged with greenish-yellow, 

 Air. 50-70 mill. 



Red Sea; Indian Ocean; New Caledonia; Philippines, etc. 



Operculum (PI. 60, fig. 41.) circular, with four whorls and nucle- 

 us placed one-third the distance across the face; outside convex, 

 shining, bright green on the center, margins brown on one side, 

 white upon the other, slightly granulose about the edges.
