Mindorana, and promises to do so oftener, which gives, in fact, a new 
feature to the work. The plates of the sixth number comprise the 
genera Piipa^ Planorhis, Clausilia, Helix, with their varieties and 
monstrosities. Of exotics there are Helix pulcherrima, hoimastoma, 
and some species from the Canary Islands and Madeira. 
An Index Molluscorum Grcenlandiae, by Moller has appeared. (Na- 
turhistorisk Tidskrift. Utgivet af Henrik Krover, 1842, iv. p. 76.) The 
work has also been published in a separate form, under the same title, 
Hafnise, 1842. The detailed analysis will be given below. Many 
species are new. 
Cantor remarks, on the Fauna of Chusan, that the Fresh-water Mol- 
lusca are rich in forms : some approach to European species, three are 
identical with Indian, viz., — Helix tapeina, Benson, Planorhis com- 
pressus, Hutton, and Helix naninodes, which last is also found at 
Singapore. (Ann. ix. p. 277.) The species, among which there are 
three new genera, have been described by Benson. (Ibid. p. 486.) 
In the Bulletin de I’Academie de Bruxelles, vol. ix. 2, p. 340, are to 
be found diagnoses of some new species of living and fossil shells by 
Cantraine, which belong to the basin of the Mediterranean. The living 
species are mentioned in a future part of this report. 
Many remarks, on the presence of Mollusca, are to be found in the 
Reports of Journeys in Dalmatia and Monte Negro, by Kiister. (Isis, 
1842, p. 283, 609, 743, and 847.) 
Petit corrects, in the Rev. Zool. 1842, p. 232, the synonymes of 
several Shells, which had been described by R. P. Lesson in the same 
journal. Lesson’s Fusus funiculatus is = F. Dupetitthouarsii, Kiener ; 
Fusus Rosa-ponti is Turhinella multinoda, Auct. Lesson cites the 
Mitra casta, M. hicolor, Oliva tuelcana, and 01. puelcliana of D’Orbigny, 
as belonging to one species of Mitra. This the author denies from his 
own inspection of the specimens. 
George Hyndman gives a list of thirty-nine species of Mollusca, which 
he obtained, with the dredging net, about two miles east of Sana Island, 
at the depth of forty fathoms. (Ann. x. p. 19.) 
W. Thompson has added a list of Mollusca (ibid. p. 21), found also 
with the dredging net, at a great depth on the Scottish coasts. From fifty 
fathoms, eight miles S. S. W. of the Mull of Galloway, he obtained five 
living species and three dead ; from 110 to 140 fathoms, five miles S. W. 
of the Mull of Galloway, one living species and six dead ; from 14.5 
fathoms in Beaufort’s Dyke, about five miles S. W. from the Mull of 
Galloway, eight living species and ten dead. 
D’Orbigny has presented to the Society Philomatique, some eggs of 
the Voluta hrasiliana. They have a diameter of seventy millini., while 
the animal itself has only 200 ; they are oval, and have a cartilaginous, 
pliant, and transparent shell. Each egg contains fifteen or twenty
