 pl. 16, fig. 53, 53 



L'Océan des grandes Indes (et Nouvelle-Hollande, 1822); mon cabinet; 

 length 9-11 mm; mss. 4 ex. — Collection Lamarck, Geneva: 8 spécimens. 



The collection now contains 8 spécimens which are mounted on a de Lessert 

 tablet; ail the spécimens are badly worn and stained. Spécimen No. 1108/14: 

 10.0 x 5.5 x 5.6 mm, has been selected as the lectotype of M. pediculus; this is the 

 spécimen which has been flgured by Kiener. The lectotype is worn and faded and 

 has 4 whorls and a worn apex; it is orange-brown in colour, ornamented with 

 white spiral cords. Sculpture consists of 12 prominent spiral cords on the body 

 whorl and 4 cords on the penultimate whorl; interstices are sculptured with axial 

 striae. The aperture is narrow, smooth within, the labial lip is thick and crenulate 

 and the columella has 3 folds. 



Lamarck's species is the Mitra pediculus auctt. ; in live-taken spécimens the 

 white spiral cords contrast with the dark reddish-brown colour of the shell. The 

 species is widely distributed throughout the tropical Indo-Pacific.

1822. Colombella bizonalis Lamarck, Anim. s. vert., 7:294, No. 6 



Habite...; mon cabinet; length ÎO 1 /? lig. = 23.6mm; mss. 2 ex. — Collection 

 Lamarck, Geneva: mixed with spécimens from the de Lessert collection. 



We have selected as lectotype of C. bizonalis a spécimen which closely 

 approaches Lamarck's given dimension, and which resembles the spécimen flgured 

 in the Encycl. Méth., (pl. 375, figs. 7 a, b), except that the pattern is faded. The 

 lectotype No. 1 108/25: 22.7 X 14.2 x 15.4 mm, is rather worn and faded, and has 4 

 whorls and a worn apex; itisfawn in colour, ornamented with white, broad axial 

 lines. The only visible sculpture consists of ca. 6 spiral cords on the siphonal 

 fasciole. The aperture is narrow, smooth within, the labial lip is thickened with an 

 interior tooth-like swelling, and the columella has 4 folds. 



C. bizonalis is not a columbellid, but is a synonym of the common Indo-Pacific 

 species Mitra ( Strigatella ) litterata (Lamarck, 1811). The generic name Columbella 

 has been misspelled " Colombella " by Lamarck.
