BUCCINUM TOTTENII. 113 



Var. icenica, nov. Plate IX, figs. 7, 8. 



Varietal Characters. — Differing from the type form of B. riwridionale in its 

 smaller size and in its stronger sculpture ; the spiral lines, which are slightly raised 

 and clearly cut, are closely crowded together, especially on the upper and lower 

 portions of the whorls ; the longitudinal plications are confined to the upper whorls, 

 being small and numerous ; the whorls are decidedly convex, the last is tumid 

 and the suture is deeper. 



Dimension,^. — L. 24 — 30 mm. B. 15 — 20 mm. 



Distribution. — Not known living. 



Fossil : Icenian Crag : Bramerton. 



RemarliS. — Examples of this charming and distinct little shell, which, as far as 

 I know, has only been obtained from the Icenian Crag of Bramerton, are to be 

 found both in the Cambridge and Norwich Museums, those figured being from the 

 Fitch collection at the latter place. It approaches B. ciliatum in sculpture, but 

 differs from it in form, and appears to associate itself more nearly with 

 B. meridionah', of which species it may be regarded, I think, as a dwarf variety.^

pi. vii, figs. 13—17. 



Specific Characters. — Shell ovato-conical, whorls 6 or 7, decidedly convex, the 

 last excavated below, two-thirds the total length ; ornamented by numerous flexuous 

 longitudinal plications on the upper whorls and on the upper part of the last, not 

 very prominent, which do not reach the bottom of the shell, and by well-marked, 

 rounded spiral lines, sometimes with finer ones intervening, especially on the 

 body- whorl ; suture deep ; mouth oval, angulate above ; canal open, very short. 



Dimensions. — L. 45 — 60 mm. B. 28 — 35 mm. 



1 Kiister figured a shell in the Conch. Cab., vol. iii (1858), pi. ix, fig. 4, as B. cyaneum, which to some 

 extent resembles my fig. 8. Much difference of opinion exists, however, as to the latter species. The 

 figure originally given by Chemnitz in the Conch. Cab. (pi. clii, fig. 1448) is that of a very different 

 shell; Eeeve's figure, again (pi. ix, fig. 69), differs from both of them.
