A cornmo7i species in the South of Europe. Pulteney, ivhose 

 specimen was Ji(jured in the " Linnean Transactions" mentions it 

 as a Dorset species, hut this locality has never been trusted to.

Shell fusiform, not slender, nor cylindrical, but much attenu- 

 ated above, and a little swollen at the penult and antepenult 

 volutions ; more or less strong, not variegated, ash-coloured, with 

 extremely fine and numerous raised longitudinal threads that are 

 narrower than their intervals. Whorls nine, flattish, rather 

 broad ; the apical coils rounded and smooth. Mouth large, 

 broadly and somewhat squarely oval, the cavity itself obliquely 

 subpyriform : the peritreme free, white, strong, and broadly 

 reflected all round. 



" The drawing of C. solida, in Kenyon's paper on British Shells (Mag. Nat. 

 Hist. vol. i. p. 42G, f. 183, m), is merely illustrative, and not avowedly taken 

 from a British specimen. Similarly, the rude representation (tig. 183, /) of what 

 is termed tlie C. ventricosu of Draparnaud, is merely given from Mr. Keiiyon's 

 belief that it is identical with our hiplicata.
