Paludinidas. 
Mr. Tryon insists upon tlie importance of the differences in the number 
of bands in the species of Vivipara [^Paludina] which are in other respects 
similar to one another j all the true North American species have four bands, 
if they have any ; the Cuban species, hermondiana (Orb.) has only two j the 
two European are three-handed ; those living in Asia and Australia are pro- 
vided with more numerous narrow bands. Am. Journ. Conch, ii. p. 109, 
110. [The Recorder is able to confirm this, especially with regard to the 
Paludince of Siam and Sumatra, P. polygramma and surnatremis. He takes 
this opportunity of correcting an error in the Record for 1866, p. 268, where 
it should be read, Paludina lineata, Val. = multilineatay Say = hengalensisf 
Lam. j this is not the North American four-banded shell, which is analogous 
to the European three-banded species.” Kuster first identified them ; and 
several authors followed himj but Valenciennes, in the “Observations 
Zoologiques ” which form part of Humboldt’s celebrated description of his 
American voyage, clearly states that his Paludina lineata has numerous bands. 
Therefore the American four-handed species must be called P. lineata (Kuster), 
not P. lineata (Val.), or receive another name.] 
Hr. VON Frauenfeld has published some remarks on about thirteen spe- 
cimens of Indian and Australian Pa/Mc?mtc, Verb, zool.-bot. Ges. Wien, 1866, 
pp. 197-199. Vivipara gassiesi, sp. n., from Anam. He continues to regard 
V.faUax and V. maheyana as distinct species.

Bithinia lucensis and B. saviana, sp. n., Issel, Molluschi di Pisa, pp. 30, 31 ; 
the first from the thermal waters of Lucca, the second from those of S. Giuliano, 
near Pisa. The author states that the latter exists in some private collections in 
Tuscany under the name of B. thermalis (L.), which, in his opinion, is an erro- 
neous determination, the true thermalis being an Jlydrohia living in Abano, 
near Padova. [This is not correct ; Linne himself states that his Turbo 
thermalis lives “ in aqua dulci prope Pisamj” and the Recorder is inclined to 
regard Issel’s B. saviana as the true thermalis of Linn^. The shell from 
Abano was confounded with Linne’s thermalis first by Olivi, and hence by 
almost every subsequent author j but LinmS’s diagnosis agrees so little with
