Station Till, Logs 12, 30, 35. Loth as I am to alter the 

 -^ell-known name Adeorhis for this species, there seems to be no 

 doubt as to to the propriety of so doing. The only species of 

 S. Y. Wood's genus Adeorlis, which is described and figured, 

 is A. striatus (= Valvata ? striata, Phil.). This, the first 

 species, becomes the type and the generic name, belongs to 

 the species usually known as Circuliis striatus, Ph. (= Circulus 

 Duminyi, Jeff.). 



The name Tormis of Turton, though published anonymously, 

 antedates that of "Wood, even though this were valid. But 

 "Wood's name being inadmissible, Tormis will stand on the 

 strength of, and dated from, Jeffery's "British Conchology " 

 (vol. iv., p. 231), if the original anonymous publication be 

 unrecognized. The ITarquis of Monterosato has for years used 

 this emended nomenclature in his correspondence with me, and 

 the name Tornus is used by Sacco in the present year (Bull. 

 Mus. Turin). 



The radula of this species is characteristically Eissoid, and 

 very closely resembles in the form and arrangement of the teeth 

 that of Onoha striata.

 It is interesting to observe how the distribution of this species, 

 so long unrecognised in our seas, is steadily extending. It is 

 now known fi-om the X.E., W., and S.W. of Ireland as well 

 as from Scotch, llanx, and English waters.
