THE TYPES OF THE LAMARCK COLLECTION IN THE MUSEUM OF GENEVA 991 



There is an 18.3 mm long spécimen in the collection which closely approaches 

 the dimension given by Lamarck; this spécimen, however, is in such a deterior- 

 ated condition that Lamarck could have hardly based his description on this 

 particular spécimen. Spécimen No. 1108/26: 20.0 X 10.7 X 13.5 mm, has been 

 designated as the lectotype of C. hebraea; this spécimen conforms to Lamarck's 

 diagnosis in ail respects, but is a fraction larger. The lectotype has 5 whorls and a 

 missing protoconch; it is white in colour, ornamented with brown, irregular 

 maculations. The shell is smooth, except for spiral striae which are more prominent 

 on the lower half of the body whorl and become spiral cords on the siphonal 

 fasciole. The aperture is narrow, white and smooth within, the labial lip is 

 thickened interiorly and the columella is calloused and has 4 folds. 



Colombella hebraea is a synonym of the Indo-Paciflc species Mitra ( Strigatella ) 

 litterata (Lamarck, 1811).

The holotype No. 1108/6: 25.2 x 16.2 x 18.2 mm, is extant in the collection; 

 the type has been flgured in the Encycl. Méth.. The holotype has 7 whorls and a 

 white worn apex; it is dark brown in colour. Sculpture consists of ca. 20 axial ribs 

 on the body whorl and 17 on the penultimate whorl; the axial ribs are cingulate at 

 the sutures, and interrupted on the lower half of the body whorl by prominent, 

 coarse and somewhat nodulose spiral cords. The aperture is constricted, the labial 

 lip has 7 prominent white denticles and the pariétal wall has a distinct white 

 callus; the columella is white and has 4 strong folds. 



Cancellaria ziervogeliana has been wrongly assigned to the family Cancel- 

 lariidae. It belongs in the synonymy of Zierliana ziervogelii (Gmelin, 1791), a 

 species living in the Indo-Pacific région.
