Only the spécimen which has been figured in the Encycl. Méth., is extant in 

 Lamarck's collection. This spécimen No. 1102/53: 50.0 X 13.9 x 24.4 mm, is 

 designated as the lectotype of M. taeniata. The spécimen has 11 slightly convex 

 whorls and a missing protoconch; it is orange in color, with broad white spiral 

 zones at the sutures and 3 dark brown spiral lines on the body whorl and a single 

 line on earlier whorls. The body whorl is sculptured with 12 axial ribs and the 

 penultimate with 14. The interstices have deep spiral grooves, and the siphonal 

 fasciole nodulose spiral cords. The aperture is narrow, pariétal wall with a callosity, 

 the labrum has 7 lirae and the columella 5 folds. The number " 22 " is written 

 inside the aperture. 



Lamarck's référence to Chemnitz (1788, Vol. 10, p. 173, pl. 151, figs. 1444-45) 

 is erroneous; the cited figures represent the species Vexillum regina (Sowerby, 

 1828). 



Vexillum taeniatum (Lamarck), is an earlier name for the species V. vittatum 

 (Swainson, 1821); the latter is the form with angulate whorls and coarser, less 

 numerous axial ribs. This somewhat rare species occurs in scattered localities 

 throughout the tropical Indo-Pacific.
