Shell with about eight smooth costse, and wider interspaces 

 covered by revolving striae ; brownish, with the ribs white 

 towards the aperture. Length, 8 mill. 



West Coast of Africa. 

 M. STELLATA, Stearns. PI. 34, fig. 84. 



Shell turreted, yellowish, tinged more or less with reddish 

 brown; whorls seven, angulated above; suture distinct; with 12 or 

 13 strong, smooth longitudinal ribs, extending to the extremity 

 of the basal volution, which also shows near its termination a 

 few revolving lines ; labrum effuse, externally much thickened, 

 deeply notched near the suture. L. '35, lat. -14 inch. 



Tampa Bay, W. Florida. 



The lip and columella in most specimens are dark ferruginous 

 brown. I may add to the above description that the inter- 

 spaces . of the ribs, in one of the specimens before me, are 

 covered with fine revolving striae, and that another has a faint 

 central band. It has not been figured hitherto, and I therefore 

 give an illustration from a specimen from Tampa Bay which 

 appears to fairly represent the typical form. 



M. LAQUEATA, Reeve. PI. 18, fig. 30. 



Ribs stout, few, remote ; sinus not very distinct ; dull white. 

 Considerably magnified, but no dimensions given. 



West Indies (d'Orbigny).

 mentioned in the description. 



M. LUCTUOSA, d'Orb. PI. 22, fig. 47. 



Whorls very slightly round-shouldered, yellowish brown, with 

 about eleven darker longitudinal ribs, the interstices with 

 revolving striae ; aperture and lips dark brown. Length, 11 mill. 



Cuba, Guadeloupe. 



I am not acquainted with this species. Mr. E. A. Smith has 

 supposed it to be a Drillia, and as the specific name is preoccu- 

 pied in -that genus by Hinds, he has changed it to P. Cubensis. 



M. PENTAGONALIS, Gray. PI. 21, fig. 30. 



Shell white, smooth, longitudinally five-ribbed, ribs pointed at 

 the shoulder. Length, f> mill. 



St. Vincent, West Indies.
