size in the spiral ridges gives a lineated appearance to that 

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

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

 Brixham and Plymouth (Jordan) ; Ban try Bay (Hum-

 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-

 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

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