p. C22. litiorm (Phil,). The figure of the animal given hy Philippi in 
Wiegmann’s Archiv and reproduced by Gray, Fig. of Moll. An. ii. pi. 125. 
f. 6, is not that of an animal belonging to the genus Asshnmea. 
p. 654. thermalis (L.)* The locality given by Linne is not Abano (in 
Venetia), but Pisa in Tuscany ; and his description cannot be applied to the 
well-known Species of Abano, which is considered to be thermalis (L.) by 
most authors and even by Hr. v. Frauenfeld himself. Also Mr. Hanley 
appears to have have had a different species, nearer to the true Bitliynia. 
Therefore we think the species of Abano may retain the name aponensiSf 
which we gave to it nine years ago, and which we have never cancelled 
(p. 578). 
p. 660. vivipara (L.) and (Frauenfeld), p. 658. Helix vimpara (L.) 
includes, without doubt, the two species distinguished afterwards by 0. Fr. 
Muller as vivipara and fasciata. Therefore we think these names should be 
retained. But if the name of vivipara should be rejected for the larger and 
more common species, it must be called listeri (Forbes), this name as well as 
that of contecta (Millet) having the priority before vcra, Frauenfeld.” 
p. 661. vulyaris {Paludinella), Oersted, is described in Oersted, ^‘De regioni- 
bus marinis,” Diss. Ilavniae, 1844, 8vo, p. 69.

Bithinia spiralis, Guppy, Ann. <fe Mag. Nat. Hist. 1864, xiv. p. 244, from 
Trinidad. [Is to be compared with Paludina coronata (Pfr.) from 
Cuba ; there is also a very similar shell in the Lake of Valencia, Vene- 
zuela.] 
Paludomus cyanostomus, Morelet, J ourn. Conch, p. 288, from Siam. 
VALVATIDiE. 
Valvata. Magnified figures of V. alpestris (Blauner), piscinalis (Miill.), 
ohtusa (Brard), and contorta (Miill.) are given by Bourguignat, Malaco- 
logie d’Aix-les-Bains, pi. 1. f. 6-25. [The differences between them consist 
chiefly in the elevation of the spire and the corresponding narrowness of the 
umbilicus — characters which are known to vary considerably in every dozen 
of specimens found together on the shores of the larger lakes of Germany, 
and which, therefore, are of but little value for specific distinction.] 
Valvata aggliitinans, Guppy, Ann. & Mag. Nat. Hist. xiv. p. 245 j from 
Trinidad. 
Ampullariida?. 
Ampullaria jjalustris, Morelet, Journ. Conch, p. 158. Lake Ebrie, near 
Senegal. 
Ampullaria pwpttrascens, Guppy, Ann. & Mag. Nat. Hist. xiv. p. 248, 
from Tiinidad; allied to A. chemnilzii, and belonging to the genus Ponms 
(Adams). 
Eggs of Ampullaria {Marisa) cfusa are described by the same author, 
ibid. p. 244.
