Lamarck's holotype No. 1107/99: 25.3 x 12.1 x 16.1 mm is extant in the 

 collection. The spécimen is worn and juvénile, with 6 whorls and a missing 

 protoconch; it is tan in colour, ornamented with a whitish band on every whorl. 

 Sculpture consists of spiral striae on early whorls and near the suture on the body 

 whorl; the siphonal fasciole has 10 spiral cords. The aperture is moderately wide, 

 smooth within, the labial lip is thin and unformed and the pariétal wall has a 

 white callus; the columella has 4 white folds.

We have selected the spécimen figured in the Encycl. Méth., and by Kiener as 

 the lectotype of M. coronata. The spécimen is immature, worn and faded, with 6 

 whorls and a worn protoconch; it is brownish in colour, ornamented with a 

 continuous white band at the sutures. Sculpture consists of ca. 19 deeply punctate 

 spiral grooves which become spiral cords half way down the body whorl; the 

 penultimate whorl has 6 spiral rows of grooves, and the sutures are coronate. The 

 aperture is narrow, smooth within, the labial lip is thin and crimped anteriorly, 

 and the columella has 5 white folds. 



The paralectotype is more mature, and is the more usual form of the species; 

 it has only a narrow presutural band onto which white axial bars descend from the 

 sutures. The paralectotype is more worn, and the sculpture is less prominent.
