by two cords, the upper one bordering the canal of the upper whorls, the lower cord is of the 

 same construction as the other one, and the interstice is likewise ribbed, base slightly convex, 

 with 5 strongly crenulate spirals, except the peripheral one and placed at some distance from 

 the latter, being separated by a rather -broad, concave, ribbed space, the innermost cord borders 

 the large, pervious, funnel-shaped umbilicus; the base is more or less variegated with white. 

 Aperture subquadrangular, canaliculate where the cords end; columellar margin with a groove 

 in its upper part. 



Alt. 3Y3, lat. 9; apert. alt. 2^3, lat. 2^j„ Mill. 



This species is allied to T. dorsuosa^ but may immediately be distinguished by the ribbed 

 upper surface.

Stat. 215. North point of Kabia-island. Reef. 701 M. Stone. I Spec. 



The specimen is larger than the quoted figures, its altitude is 14 Mill., its diameter 13. 

 Tryon says: "Alt. 20 mill.", but his figure is only 13 Mill. high. 



5. Torinia madurensis n. sp. PI. XIV, fig. 4. 



Stat. 51. Madura-bay. 69 — 91 M. Fine grey sand, coralsand with shells. I Spec. 



Shell small, depressedly conic, white, with traces of a brownish epidermis, nucleus glossy, 

 brown, postnuclear whorls 3^/„, slightly convex, nearly angular a little above the suture, by the 

 prominence of one of the spirals, of which there are 6 on the penultimate whorl, these spirals 

 are separated by narrow, shallow grooves and crossed by oblique striae or grooves, which 

 render the spirals crenulate, moreover finer spiral striae, more clearly visible in the interstices, 

 and fine growth-striae cross each other. The fifth of the spirals, counted from above is the 

 most prominent one. Base moderately convex, with 9 spirals, of which the infraperipheral 2 are 

 prominent; those standing on the basal surface are broader and flat, the innermost is coarsely 

 crenulate. Umbilicus pervious, funnel-shaped. Aperture subcircular, its columellar margin expanded 

 and slightly reflected over the umbilicus. 



Alt. 4^4, lat. 6; apert. alt. 27,, lat. 27, Mill. 



This shell is allied to the preceding species, but it is smaller, broader and has the whorls 

 more conspicuously separated.
