Specific Characters. — Shell elongate, turreted, imperforate; whorls disjoined, 

 decidedly convex ; ornamented by very fine net-like cancellation, the transverse 

 and longitndinal ridges being nearly eqnal in size, together with a few strong and 

 prominent varices; snture deep, channelled; mouth snbcircular, with a strong 

 basal ridge. 



Dimensions. — L. 25—30. B. 10 mm. 



Distribution,. — Not known living. 



Fossil: Coralline Crag: Sud bourn. Corner, Sutton, Boyton. 

 Waltonian : Walton-on-Naze (Kendall), Little Oakley. Newljournian : AYaldring- 

 field, Sutton, Felixstowe. 



Scaldisien : Dutch borings (Tesch). 



Miocene: Piedmont (de Boury). 



UemarlvS. — This seems to me a distinct form allied to 8. fimhriosa, but smaller 

 and more slender, with much finer sculpture, the varices standing out prominently 

 from the fine intervening cancellation. Originally referred by Wood to the S. vari- 

 cosa of Lamarck, it was afterwards regarded by him as a separate species under 

 the present name. As to this shell, Jeffreys remarked in 1871 [op. cit., p. 491) 

 " not Turbo varicosns, Brocchi, nor S. varicosa, Lamarck," regarding it in a 

 different list (p. 145) as a variety of S. fiinbriosa, but he afterwards identified it 

 Avith a shell figured by G. O. Sars as S. inirlcosa {op. cit., pi. xxxiv, fig. 9). Sub- 

 sequently, however, in 1884, the latter described it, together with another species 

 — the S. obtusicustata of the same author (pi. xxii, fig. 9) — as new, under the name 

 of S. coarctata} In the face of this cojiflict of opinion I have no hesitation in 

 adopting for the present form Wood's name of S. funiculus as that of a distinct 

 species. Prof. Sacco describes a somewhat similar fossil from the Italian Pliocene 

 as Girsotrenia varicosum var. liyusticiv^ ; he notes its resemblance to our Crag shell, 

 but does not consider it the same, nor do I.
