46 DR. GWYN JEFFREYS ON THE MOLLUSCA OF THE [Jan. 20, 



Family XXV. Capulid.«. 



This would seem to be the natural position of the family. Mr. 

 Jabez Hogg, in an excellent and beautifully illustrated paper on the 

 lingual membrane of Mollusca (Trans. Roy. IMicr. Soc. xvi. n. s.), 

 says as to Gapulus hungaricus, " Dendtioa is seen to be almost 

 identical with Felutina.'^

Distribution. From arctic Norway to the Mediterranean, ^gean, 

 and Adriatic, New England {Ferrill) ; 0-458 fms. 



Fossil. All the Tertiary fossiliferous beds in Europe ; 0-1360 fi. 



There are many obsolete and useless synonyms, including so-called 

 species of the fossil so-called genus Brocchia. See my ' Notes on 

 Brocchi's Collection of Subapennine Shells ' in the Quarterly Journal 

 of the Geological Society for February 1884. The young has been 

 called Capulus or Peleopsis militaris. 



This common shell attains to a considerable size. I have one 

 from Algiers exceeding two inches in length ; and I noticed a still 

 larger specimen in Dr. Tiberi's collection from the Bay of Naples. 

 Owing to its quasi-parasitic habit it is very liable to distortion 

 in various ways, being sometimes compressed laterally, expanded, 

 obliquely formed, or angulated, as in Crag specimeus of Searles Wood 

 and Mr. Alfred Bell.

Distribution. Norway, from Lofoden I. southwards {Loven and 

 others), Shetland {Bar lee). New England and G. Maine (Ferrill) ; 

 4|-317 fms. 



Herr Friele informs me that the animal is of a pale flesh-colour, 

 the head not very prominent and notched in front ; tentacles rather 

 long and pointed ; eyes on small bulbs near the outer base of the 

 tentacles ; the foot longish and narrow, broader, truncated, and 

 horizontally cloven in front. Professor G. O. Sars has lately 

 dredged on the west coast of Norway a very large and living 

 specimen, more than an inch long. 



The operculum is small, acutely triangular like that of Trophon 

 and Fusus, and is ridged transversely.
