T. CAPITATA Pilsbry, n. sp. PI. 50, figs. 35, 36, 37. 



Shell minute, white, smooth except for slight, curved growth- 

 stride; cylindrical, rather obese, with short spire and very large pro- 

 jecting nucleus. Post-apical whorls about 3, hardly convex, separ- 

 ated by deeply channelled sutures ; last whorl obese-cylindrical. 

 Aperture long and rather narrow, slightly more than three-fourths 

 the length of the shell ; columella calloused, having a weak fold 

 and a slight umbilical groove.

Singapore (S. Archer), 5 specimens. 



The columella is shaped like that of T. singaporensis, but the spire 

 is notably shorter, and the entire form more obese. This should be 

 compared with T. fusiformis Ad., authentic specimens of which I 

 have not seen. The uptilted apex is unusually large, and in the 

 type specimen its spire is directed forward. Fig. 37, represents the 

 spire viewed from the face of the shell; fig. 35, the spire viewed 

 from behind, showing the umbilical aspect of the nucleus. 



T. VOLUTA Quoy & Gaimard. PI. 22, figs. 29, 30, 31. 



Shell cylindrical, elongated ; smooth except for sharp, fine, 

 remote spiral striations ; white; spire produced, the apex acute; 

 suture channelled, the top of the whorls excavated into another 

 channel bounded by the upward continuation of the inner lip.
