size in the spiral ridges gives a lineated appearance to that 

 part of the epidermis on the body- whorl which is of a paler 

 colour and situate below the periphery ; the canal is propor- 

 tionally shorter, much wider, and more open ; the outer lip is 

 sinuated in the middle ; operculum ambercolour. L. 2-25. 

 B. 1-15. 



Habitat : Exmoutli (coll. Clark) ; Torquay (King) ; 

 Brixham and Plymouth (Jordan) ; Bantry Bay (Hum- 

 phreys and J. G. J.) ; Waterford, Wexford, and Dublin 

 coasts (Walpole). It inhabits sandy ground in the 

 coralline zone, and was in most of the above instances 

 procured by trawling; I dredged it in about 18 f. Belle- 

 ile, Morbihan (Delaunay, fide Tasle, as F. propinquus); 

 Loire-Inferieure, with F. gracilis (Cailliaud, as the same) ; 

 Gulf of Gascony (D'Orbigny pere) ; ? south-west of 

 France (Fischer, also as F. propinquus); Gulf of Lyons, 

 from the stomach of a gurnard (Martin) . 



The fry are as distinct from those of F. propinquus 

 as the adult of each from the other. 



Lamarck gave no habitat ; but his description is quite 

 suitable to the present species. His reference to Bom's 

 figure of F. vulpinus was conjectural and erroneous. 



B. Decussated by longitudinal strise or ribs and spiral ridges.

Body white or creamcolour, with a slight tinge of flesh- 

 colour : mantle sometimes edged with brown: pallial tube ex- 

 tensile, occasionally protruded beyond the canal, with an ex- 

 panded or trumpet-shaped opening: proboscis exceedingly long,
