This shell has quite the aspect of a Serpula ; but it differs in the 

 manner of its contortion and the internal lamina on the columella, 

 which I have only seen in the middle whorls of three or four speci- 

 mens. It answers quite in form, and nearly in position, to that in 

 V. subcanceUatiis ; but 1 am not able to find the opposite one. The 

 walls of the shell are exceedingly thick in proportion to the aperture, 

 nearly corresponding to the radius of the aperture ; in a few speci- 

 mens they are rather thin. Some specimens are coloured inside with 

 a beautiful lilac, which is to be seen outside, but is there more feeble ; 

 but I am not quite sure if this is not caused by the dying animal, as 

 may sometimes be seen in shells, chiefly of Purpura. The reason 

 why I do not distinguish this shell specifically is, partly because it 

 differs only from " h Lispe " in its colour and locality, and partly 

 because it may possibly be only the young stage of F. subcan- 

 cellatus, var. scolopendrina, the first whorls of which show the same 

 dull-white colour, but which is much more strongly annular. I have 

 seen from ten to fifteen specimens. {Mus. Keg.)

" Les tubes sont toujours petits et contournes en spirale verticale : 

 les tours sont egalement elargis, et tellement rapproche's qu'ils se 

 reunissent les uns aux autres ; ils sont cylindriques, quelquefois un 

 peu anguleux a cause de 2 ou 3 petites cotes longitudinales qui 

 occupent toute la longueur des tubes ; les interstices entre les cotes 

 sont stries transversalement, les stries sont tres-fines, souvent a peine 

 visibles ; on compte 8 tours sur la longueur du tube de 5 lignes ; 

 quelquefois les tours sont encore plus etroits, et de 10-1 2 sur la meme 

 longueur. Selon Bronn V. intortus, Lam., quoique elle ne soit 

 jamais fixee par le cote, comme celui-ci, mais par la base, de laquelle 

 elle s'eleve verticalement, n'est jamais comprime'e comme celui-ci, 

 mais cylindrique, egalement grosse dans toute sa longueur, et par con- 

 sequent pas plus grosse a I'extremite superieure. Outre cela, celui-ci 

 n'atteint jamais au-dela de 6 lignes, le V. intortus, an contraire, est 

 tres-long. L'extremite superieure offre un bout tout droit, mais de 

 la meme dimension que les tours pre'cedents ; il est lisse ou tres-
