is V. {pupa) Lilljeborgi of Westerlund, and he pro- 

 poses to add it to the British list under that name. 



In the 'Annals and Magazine of Nat. Hist.' for 

 Nov. 1878, he says, "The shell of V. Moulinsiana is 

 rather more swollen or barrel-shaped than that of 

 V. Lilljeborgi, and the labial rib is much stouter." A 

 short time ago I paid a visit to Dr. Gwyn Jeffreys at 

 Ware Priory, when he kindly showed me specimens of 

 the two shells, which certainly differ from each other 

 in the manner described ; but unless Dr. Westerlund 

 noticed in these forms other and stronger distinguish- 

 ing features, I think he is scarcely justified in regard- 

 ing them as distinct species. 



The above description of the shell of V. Moulin- 

 siana is from Hampshire specimens kindly given to 

 me by Mr. Groves, who informs me that the number 

 of teeth in shells from that locality is usually five, 

 although there are sometimes one or two additional 

 denticles. 



Van bidentata. " Labial or palatal teeth wanting." 



This is recorded in ' British Conchology ' as a 

 variety of the shells found in Ireland by the author of 

 that work ; it must therefore be referred to V. Lillje- 

 borgi, if Dr. Westerlund is correct in regarding that 

 form as specifically distinct from V. Moulinsiana. 



3. V. PYGM/E'A,* DRAPARNAUD. PL. IX. 



Body of a dark slaty-grey colour, with minute, round, close-set 

 tubercles ; tentacles very slender, almost touching each other at 

 the base, but widely diverging above, bulbs oblong, greyish at 



* Dwarf.
