Bithynia stagnalis,'' Faster, one of the IlydrohicB living in the province of 
Verona, is considered [probably wrongly] to be identical with the sub- 
marine II. staynalis, Linnd ; the Veronese species determined by Menegazzi

Pyrgnla anmdata, Jan. Betta, Moll. prov. Veron. pp. 126-128, discusses

Fr. Berl. vol. i. 1824, p. 216, pi. 9 (3) f. 6) as Turbo anmdatus, Gmelin.

Tricula montana, Bens., is a true freshwater shell ; its tentacles are long, 
filiform, and the eyes placed behind them, just as in the terrestrial Aciculuy

3000 feet above the sea. Blanford, Ann. N. H. (4) vi. p. 369.

Bourguignat, Ann. Mal. p. 37, mouth of the Danube. 
Vivipara lineata (Kiister not Val.) is tho true name of tho American 
species ; the occurrence of Valenciennes’s specimens in India is attested by a 
MS. label in the Museum of Paris. Binney, Ann. Lyc. N. York, ix. pp. 296- 
297, and Tryon, Am. Journ. Conch, vi. p. 176. [The Recorder made tho 
same statement in 1866 (Mal. 131. xii. p. 160).] 
Tuloioma magnijica (Conrad), its lingual dentition described and figured by 
Binney and Bland, Ann. Lyc. N. York, ix. pp. 292-294 : it is very similar to 
that of Vivipara ; also the right tentacle is said to be broad [probably only 
in the males, as in Viviparo\
