16 SOLENID.E. 



All writers on Scandinavian mollusca have enume- 

 rated the present species in their lists, from the Loffo- 

 den Isles to Kiel Bay, in 3-50 f.; Collard des Cherres, 

 Cailliaud, and Tasle have found it in Brittany ; M'An- 

 drew dredged it in the south of Portugal, off Gibraltar, in 

 the Gulf of Tunis, and Sicily, in 15-40 f. ; and Wein- 

 kauff procured it by the same means at Algiers in 20 f. 



This pretty shell was discovered by the Rev. Hugh 

 Davies about the year 1770 on the Carnarvonshire 

 coast. Clark savs that on both the mantle- tubes " are 

 a few, large, rather long, white filaments, springing 

 from the body of the common sheath, just below the 

 siphon al orifices." I did not observe them in any of 

 the specimens that I examined. The foot is sometimes 

 red or pink of various shades. The shells are not unfre- 

 quently taken from the stomachs of haddocks. They 

 are occasionally distorted. 



It is the S. pygmceus of Lamarck. S. pellucidus, 

 Spengler (from Chemnitz) is a tropical species, from 

 Nicobar. 



B. Shell more or less curved, tubular, and rather solid ; hinge 

 at one end, and furnished with cardinal and lateral teeth.

Body somewhat compressed, pale drab : mantle having <i 

 narrow fringed slit in the middle of the anterior side : tubes 



Palermo and Panormi as two places, being misled by Philippi using 

 both names, in his work on the Sicilian Testacea, sometimes as different 

 habitats of the same species. Panormus or Panormum is the ancient 

 name of Palermo.
