L'Océan des grandes Indes (error!); mon cabinet; length 46-50 mm; mss. 

 5 ex. — Collection Lamarck, Geneva: 1 spécimen. 



The spécimen remaining in Lamarck's collection and figured in the Encycl. 

 Méth., No. 1102/49: 45.4x 17.1 x 19.9 mm, is here designated as the lectotype of 

 M. gramdosa. The spécimen is rather worn and faded, and has 8 whorls and a worn 

 apex; it is brown in colour, with occasional lighter coloured axial streaks. Sculpture 

 consists of 13 granulose spiral cords and 18 nodulose axial ribs on the body whorl, 

 and 4 cords and 16 axial ribs on the penultimate whorl. Aperture is narrow, 

 whitish and smooth within and the labial lip is thick and chipped anteriorly; the 

 columella has 4 folds plus 1 intermediate fold. 



Lamarck's locality indication is erroneous; on the label accompanying the 

 type, " Amérique? " has been inserted. The species lives in the Caribbean- Atlantic 

 région, and M. granulosa Lamarck is a synonym of M. nodulosa (Gmelin, 1791).
