p. 16. — An abnormal specimen of Physa gyrina (Say), with short somewhat 
scalariform spire, is described by Conrad, Am. Journ. Conch, ii. p. 114, 
pi. 10. fig. 9 ; it suggested to him the probability that Paludina scalaris (Say) 
might be the same abnormity in a more exaggerated form. — Half-grown 
specimens of Physa heterostroplia (Say) with the last whorl suddenly enlarged 
near the' aperture have been found in almost equal number with normal 
ones at Cape Elizabeth, Maine, by Mr. Wheatley. Am. Journ. Conch, ii. p. 181. 
— A scalariform specimen of Planorhis hicarinatus (Say) is described by Tryon, 
ibid. p. 3, pi. 1. fig. 4,

** This little volume is more than it claims to be, and will 
.prove a very useful and entertaining pocket companion to the 
well posted as well as the uninitiated shell-collectors of Eng- 
land. The species are all illustrated by lithographic plates and 
woodcuts.^^ (Tryon, Am. Journ. Conch, ii. p. 285.)

Five species [Acicula lineata. Pupa edentula, Valvata con- 
torta, naticina, and the marine Ernbletonia pallida) have been 
added to a former list of the mollusks of the province Prussia 
since 1859 ; new localities are given for a few other rather rare 
species. [The first paper on this subject was published by Dr. 
Hensche in the same journal, 1861, a second in 1862.]
