52 VOLVARIA. 



M. MEDiociNCTA, E. A. Smith. PL 13, figs. 12, 13. 



Wliite, M'itli two broad light chestnut bands ; columella four- 

 plaited. Length, 6"5 mill. 



Cape Vei'd Is. 



The coloring is above and below the middle, covering the 

 body-whorl except a central white zone. 31. Bouvieri., J onsseaume 

 (lig. 13), is a synonym. 



M. RUBELLA, C. B. Adams. PL 13, figs. 14, 15. 



Ros}' white, with three faint rose-colored bands ; columella* 



four-plaited. Length, 8-11 mill. 



Jamaica and St. Thomas, W. I. 



M. navicella^ Reeve (fig. 15), is a synonym. 



M. T^NiATA, Sowb. PL 13, figs. 16, 17. 



Whitish or yellowish white, with sutural, median and basal 

 bands of yellowish brown, and a narrower band of the same 

 color between the last two ; sometimes the coloring is roseate, 

 and occasionally a pair of proximate narrow lines take the 

 place of a broad band. Length, 12-15 mill. 



Cape Verd Is ; West Indies. 



Very like M. avena, YaL, and may be only a variety of that 

 species ; its distinctive characters being a shorter spire and the 

 additional narrow band. M. Verdensis, E. A. Smith (fig. 17 ), is 

 identical with this species. 



M. Cessaci, Rochbrune. 



Elliptical, shining, thick; spire short, conical, obtuse; aperture 



long and narrow, a little dilated above ; lip thick ; columella 



four-plaited ; wine-red with a livid band at the top of the whorl. 



Length, 11 mill. 



Hab. Cape Verd Islands. 



Seems to be very closely allied to M. tasniata. The work 

 containing the figure of this species, arrived too late to have it 

 illustrated in the Manual. 



M. OBscuRA, Reeve. PL 13, fig. 22. 



Yellowish white, faintly four-banded, the bands terminating 

 in spots on the margin of the lip. Length, 9 mill. 



Habitat unknown.
