Paludina. A. Morelet points out that Reeve has misapplied several names 
given by Lea, and that P. ingallsiana of Reeve (not Lea) must take the new 
name P. franmfddi (Morelet) [the Recorder long ago named it cingulata^ 
Proc. Zool. Soc. 1860], and P. umhilicata of Reeve (not Lea) the name of 
trochoides (Martens). Further, he describes more fully P. cochinchinensis 
(Morelet 1866) and eyriesii (Morelet, 1866), and suggests that sumatrensk 
(Dunker) and polygramma (Martens) may be regarded as varieties, perhaps 
of P. hengalcnsis (Lam.). Journ. Conch, xvii. pp. 192-202, 
Morelet (ibid. pp. 403-408) objects to a statement of E. v. Martens (Zool. 
Record, 1866, p. 268), viz. that Paludina angulark (Miill.) is identical with 
P. quadrata (Bens.), and not with P. costata (Q. & G.). [We must refer the 
author to the fact that 0. F. Muller gives Canton as the habitat, and also to 
the figure of Miiller’s specimen in Chemnitz, Conchylien-Kabin. ix. fig. 
1222 .]

Melantho. J. Lewis has published his observations made chiefly on speci- 
mens in the collection of Mr. Wheatley. Am. Journ. Conch, v. pp. 33-36 : 
he compares examples from various localities; and it appears as if nume- 
rous so-called species distinguished by North- American authors proved to be 
untenable, although this is not admitted by the author.
