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 striz, 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 ).

M. tuctuosa, d’Orb. Pl. 22, fig. 47. 
Whorls very slightly round-shouldered, yellowish brown, with 
about eleven darker longitudinal ribs, the interstices with 
revolving striz; aperture and lips dark brown. Length, 11 mill. 
Cuba, Guadeloupe. 
Iam 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, 6 mill. 
St. Vincent, West Indies.
