Pythiaj Plecotrema) are terrestrial^ all belonging to the estuary- 
fauna, living in places covered by salt or brackish water at 
every tide. 
Some shells found in brackish water at Yokohama are mentioned by v. 
Martens, Preuss. Exped. Zool. i. p. 138. 
The half-salted water in the so-callod inner Skiir-gard ” near Stockholm 
is inhabited by the following mollusks, which in other localities are found in 
pure fresh water : — Limncea auricularia, L. limosa, var. haltica, L. palustriSf

anatina. Hartman, CEfvers. K. Vetensk. Akad. Forhandl. 1866, p. 390. 
A new species of the genus Assiminea, yallica, has been described as being 
found in the interior of France at salt-springs in the d(5partements do I’Ain et 
du Jura, by Paladiliie, Revue Zool. xix. p. 40. This would be the first 
example of a saltwater mollusk being found in an inland saline locality, unless 
a shell very nearly allied to Hydrdbia ventrosa (Mont.), and found dead in 
the salt lake at Mansfeld, Prussian Saxony (Martens, Troschel’s Archiv fiir 
Naturgeschichte, xxiv. 1858, p. 174), be taken as another instance, It is, 
however, desirable that the determination of the genus of the French shell 
may be confirmed by positive observation of the position of the eyes and of 
the radula. 
c. Marine Mollusca. 
1. European Seas. 
The fourth volume of Mr. J,Gwyn Jeffreys’s ^ British Concho- 
logy ^ (see Zool. Record, ii. p, 232) contains the continuation of 
the Gastropods to the Bullida inclusively; the rather difficult 
families of the Rissoidce, Pyramidellidcey and Pleurotomidce are 
worked out with the greatest care, this part containing much 
new information with regard to European species generally, 
so that the work must be consulted by every one who is en- 
gaged in the study of this subject. We are glad to hear that 
the author has since paid once more a visit to the shores of the 
Mediterranean, in order to ascertain the validity and synonymy of 
those species of the families mentioned which hitherto have been 
regarded as peculiar to that sea. It would be difficult to select 
and to enumerate all the important results arrived at by the 
author's most laborious and acute researches ; but the Recorder 
is anxious to impress on the minds of all conchologists that 
this volume also contains a large stock of personal observations 
concerning the living animals, their habits, mode of feeding, 
bathymetrical and geographical distribution, the fruits of many 
years of exploration on shore and in dredging-expeditions. To 
this volume, as to the preceding, a table is appended, showing 
at one glance the more northern or southern distribution of each 
species in Europe, the extra-European localities, and its presence 
or absence in the Upper Tertiary beds. 
Fdroer. Morch enumerates 106 marine species, most being 
identical with those of Scotland, even in their varieties. The
