Has some resemblance to the Haitian M. lineatus, but is 

 most closely related to M. pazi, from which it differs in the 

 less expanded peristome, more elaborate color-pattern and 

 more striate surface. Figured specimens are from Faral-

Shell very shortly rimate, ovate-turrite, cream-white, with 

 a dark brown band below the periphery, its lower edge den- 

 ticulate, and a small dark umbilical patch; above the periph- 

 ery there is a single spiral row of small brown dots, each con- 

 nected with a narrow oblique streak toward the suture above. 

 Early whorls usually truncate, the next two or three dark- 

 flamed. Surface striate above, the last whorl smoother, some- 

 times weakly malleate. Spire straightly high-conic, the 

 suture finely crenulate, at least above. Whorls 7-8 in trun- 

 cate, 9-10 in entire shells, but slightly convex, the last rounded 

 at the periphery and below. Aperture slightly oblique ; peris- 

 tome very slightly expanded, the columellar margin widely 

 dilated and reflexed, its face a little excavated. 



Length 11.5-13, diam. 5.5 mm.
