and the year in which, they were first stated to live in the Adriatic. 
He attributes some exotic shells to that sea, through inaccurate deter- 
minations by former authors {Artemis prostrata, Psammohia ccerulescens, 
&c .) ; Atti 1st. Venet. (4) ii. & iii. 185 pp. 
The known sea-shells from the Syrian coast, chiefly from the collection 
made by Prof. Hausknecht, enumerated by E. v. Martens, Yorderasiat.

coasts of the Mediterranean. 
Blade Sea. The known Mollusks enumerated, with some historical 
and critical notes by E. v. Martens, op. cit. pp. 69-79. Nearly all are 
identical with Mediterranean species, but many of the latter are wanting 
in the Black Sea, as stated by Aristotle ; the facies of the fauna agrees 
remarkably with that of the environs of Venice. A few Caspian species 
are also found in the Black Sea. 
Caspian Sea. The known Mollusks, from the collections of Prof. 
Hausknecht, Dr. Orth, and others, enumerated by E. v. Martens, op. cit. 
pp. 80-88. Its fauna is very peculiar, characterized by the subgenera 
Duhicna and Monodacna of Cardiicm, and by the genus Adacna ; the 
species common with other parts of Europe are either estuarian alid 
eurythermal, as Ilydrohia stagnalis and Cardium ediile, or even fresh- 
water, as Paludina and Dreissena. 
2 . Mediterranean Sea. 
The knowledge of the rarer and small shells of the Mediterranean Sea 
has been remarkably advanced by the diligent researches of the Marchese 
T. A. Di Monterosato of Palermo, who has published a paper on the 
shells dredged by himself at Cape S. Yito, in Sicily, containing 232 
species (many very rare, and some new or known hitherto only in a 
fossil state), with valuable rectifications of synonymy. J. de Conch, 
xxii. pp. 243-282. 
The papers by Brugnone and Aradas & Benoit, indicated in the 
list of titles \_suprd, p. Ill], the Recorder regrets not to have seen ; 
some species described in them are mentioned below from quotations by 
Monterosato. 
Jeffreys’ paper on the Mollusks of the Meditetranean Sea [Zool. 
Rec. X. p. 137] has been translated into German by Kobelt ; JB. mal. 
Ges. i. pp. 337-344. 
Kobelt has also published some interesting notes on rare shells of the 
Mediterranean Sea; tom. cit. pp. 107-115, 222-235, & 344-352, pis. iii., 
xi., xiv. [see below. Solarium, Mathilda, Coralliophila, Mitra, and Tri-

A. E. Yerrill has published the results of recent dredging expeditions 
on the Coast of New England: Am. J. Sci. (3) v. (1873) pp. 1-16, 
98-106; vi. (1873) pp. 435-441; vii. pp. 38-46, 131-138, 405-414, 498- 
505. J. F. Whiteaves records his own dredgings in the Gulf of St. 
Lawrence, op. cit. vii. pp. 1-9. Lists of shells are to be found, op. cit.
