ornamented with orange-brown zones and darker brown streaks within the zones. 

 Sculpture consists of ca. 14 deeply punctate spiral grooves on the body whorl and 

 4 on the penultimate whorl; the sutures are spinosely crenulate. Aperture is 

 moderately narrow, smooth within, the labial lip is bluntly crenulate and the 

 columella has 4 folds. 



The figure from the Encycl. Méth., (pl. 370, fig. 5) has inadvertently been 

 cited by Lamarck for M. puncticulata, whereas it should have been included in the 

 synonymy of the following species, i.e. M. millepora. Kiener's illustration of 

 M. puncticulata (pl. 7, fig. 20), does not quite match Lamarck's holotype in 

 shell-shape; this may be due to the différent viewing aspect of the illustration. 



Lamarck's species is the M. puncticulata auctt. ; the species has an Indo-West 

 Pacific distribution.

The selected lectotype is an immature spécimen with 6 whorls and a missing 

 apex; the basic colour is brown, and ornamentation consists of irregularly placed 

 white maculations and streaks. Sculpture consists of ca. 17 deeply punctate spiral 

 striae on the body whorl and 7-8 on the penultimate whorl; the sutures are finely 

 crenulate and the siphonal fasciole has 4 weak spiral cords. The aperture is 

 moderately wide, smooth within, the labial lip immature and crimped; the 

 columella has 5 folds. 



The third spécimen in the Lamarck collection is an undocumented spécimen, 

 46.7 mm in length. 



Mitra millepora is a synonym of M. imperialis RÔDING, 1798; the species is 

 widely distributcd throughout the tropical [ndo-Pacific.
