Dolium tenne, Menke, Synopsis, p. 143 (Young). 



The typical galea (that indicated by the synonymy) is thin in 

 proportion to its magnitude, of a pale russet colour, with indistinct 

 lighter and darker zones, a whitish posterior margin to its whorls, a 

 tawny nucleus, a pale aperture, and rounded ribs, which, although 

 alternately larger and smaller, are not, at least in the almost mature 

 stage, so very disproportionate. 



Two other forms (perchance species) require to be noticed. The 

 one which I designate var. tenebrosa is stronger, and peculiarly 

 globose, has a dark chocolate-coloured nucleus, the smaller turns of 

 a brownish chocolate hue, and the body-whorl livid brown ; the 

 throat dark chestnut, and the internal thickened edge of its outer 

 lip pure white. Its ribs, moreover, are more abruptly elevated ; 

 their intervals rather broader, more square-cut, and not intersected 

 by an interstitial costella (or raised stria) upon the lower or anterior 

 half of the body. Mr. Cuming possesses a small but exquisite 

 example of this shell : I have elsewhere seen an adult specimen stated 

 to have been found in the Red Sea. 



The other form alluded to (possibly the D. tenue of Menke) is of 

 a smaller size (that now before me is only 3-^ inches long), has the 

 body more elongated, and combines the broad sulci and the abruptly 

 prominent ribs and costellse of the last variety (?) with the pale tints 

 of the typical galea ; its nucleus is chestnut or fulvous, its aperture 

 whitish, its expanded outer lip thickened internally, and toothed as 

 in an adult galea. Mr. Cuming has received it as from China ! It 

 reminds one much of Martini's ' Braune geribte Tonne' (iii. f. 1071), 

 said to come from Guinea ; its colouring, however, is less intense. 



Dolium melanostoma, Jay.

The shell figured in Reeve's beautiful work was not perfect, but 

 is essentially the same species as that delineated by Jay. Mr. 

 Cuming possesses a superb example, and two specimens are said to 

 be preserved in the Guernsey Museum. 



Dolium zonatum, Green.

Dolium zonatum, Green, Albanv Instit. i. p. 131. pi. 4 (June 

 1830); Reeve, Conch. Icon. Dol. f. 12. 



Dolium crenulatum, Philippi, Zeitschr. Malak. 1845. p. 148 ; Neue 

 Conch, iii. Dol. pi. 1. f. 1. 



Although Crouch may have rightly divined the Linnean species, 

 the Linnean definition was too obscure to ensure certainty.
