which causes the sutures to be very deep, and the last whorl at the 

 peristome to be almost disunited from the penultimate whorl. The 

 red-brown spots on the beaded ribs and the exquisite clathrate 

 sculpture of the surface render this one of the prettiest shells in the 

 great family of Trochoid scutibranchs. In texture it resembles 

 Enida japonica and Tercica monilifera, and judging from the shell, 

 it appears to be more closely associated with the Ziziphinus group 

 than with the Gibbula or Margarita. (A. Ad.)

Shell depressedly conical, rather solid, transversely finely ridged, 

 with two or three broader ridges forming keels, the interstices crossed 

 everywhere with very fine close-set oblique striae ; pinkish or yellow- 

 ish white stained on the body-whorl with bright rose, and spotted 

 on the keels with deep purple lake ; whorls 6, angularly convex ; 

 sutures broadly and flatly channelled ; last whorl tricarinate, beneath 

 white and rounded ; umbilicus wide, perspective, crenatc within ;

The umbilicus is two mill, wide; the aperture is perfectly cir- 

 cular, 3 mill, across ; apex buff. My specimen is less strongly 3- 

 keeled than the original description and figure indicate. 



M. BELLULA Angas. PI. 41, figs. 27. 



Shell umbilicated, conoidal, rather thin, shining ; whorls 6, con- 

 vex, depressed-canaliculate above, and terraced ; the first whitish, 

 the remainder whitish, beautifully ornamented with regular, equi- 

 distant, radiating, somewhat flexuous radiating rosy streaks ;
