suhcariTiata^ p. 65. In the last species there is the same sexual difference in 
the right tentacle as in the European species. The spurious or uncertain 
North- American species are also mentioned, pp. 60-65. 
In later additional notes given by Binney in the French Journ. Conch, xv. 
pp. 430-432, Paludina carinata (Val.) and lineata (Val.) are rejected as Ame- 
rican species, and the latter is identified with bengalensis (Lam.), the types of 
Valenciennes’s species having been examined. [See on this point Martens in 
Mai. Blatt. xii. 1866, pp. 144-161 ; ' Kecord ’ for 1865, p. 268.] 
Paludina scalaris (Jay), from Florida, is a good species, at least fifty speci- 
mens having been seen by J. G. Anthony, Am. Journ. Conch, iii. p. 104. It 
is referred to the genus Physa, after the example of Haldeman, by Binney, 
Monogr. Land- and Freshwater Shells N. Am. ii. p. 96, and iii. p. 62. 
Paludina ussuriensis (Gerstf ) probably identical with P. lecythoides (Bens.), 
with three varieties, plicata, carinata^ and malleata ; P. prtBrosa (Gerstf.) = 
pachya, dophila, and chloantha (of Bourguignat), with three varieties, Icevigata^ 
plicata, and striata ; and P. limn< 2 oides, sp. n., pi. 26. figs. 2-6, are found in 
Mantchuria. Schrenck, 1. c. pp. 606-622. [The Recorder may add that P. 
lecythoides appears to be the same species as P. chinensis (Gray, in Griffith’s 
Anim. Kingd.), which latter name has priority. It is quite common through- 
out China, having been observed by himself at Canton and Shanghai.] 
Larina P hurmana, sp. n., Blanford, Journ. As. Soc. ii. p. 61, pi. 2. fig, 1, 
Myittaya Creek, delta of the Irawady. The author is not certain whether it 
has affinities with Amphibola or Velutina, and has a distinct impression that 
the shells possessed a horny operculum.” 
Bythinia tentaculata, var. obesa, of smaller size and more contracted than 
the type, the nucleus of the operculum very prominent. Intralittoral region 
to the left of the Garonne, Pool of Riviere, near Villandraut. Gassies, Malacol. 
Aquit. p. 23, fig. 6. 
Bithinia ventricosa (Leach) = (Shepp.) and B. striatula (Bens.) 
^striata (Gerstf. by mistake) =mCTM(?^ownc<^ (Bourg.), from Manchouria.

Stenothira monilifera (Benson) figured by Blanford, Journ. As. Soc. ii.

Valvatid^. 
Valvata piscinalis and V. cristata in Manchouria. Schrenck, 1. c, pp. 634- 
637. 
Valvata planorbulina et F. exilis, spp. nn., Paladilhe, Revue Zool. pp. 60, 61, 
pi. 21. figs. 23-26 and 27-30, near Montpellier. 
The North- American species are, according to Binney, V. tricarinata (Say), 
sincera (Say), pupoidea (Gould), humeralis (Say), virens (Try on), all briefly 
described and illustrated by woodcuts, Land- and Freshw. Moll. N. Am. iii. 
pp. 8-14 ; lingual dentition of tricarinata, pp. 8 & 9, operculum of the same, 
p. 8 ; living animal of sincera, p. 8. 
Valvata jelskii (Crosse). 0. A. Morch stated that this is the young state 
of a Lithoghjphus. Am. Journ. Conch, iii. p. 106. II. Crosse says in reply 
that the Lithoghjphus = Vah^ata menkeana (Jelski) is of almost equal size 
with the species of Valvata, Journ. Conch, xv. p. 291.
