whence the specimens were obtained. The author drew attention 
to a paper by Mr. Gregory, which appeared in the Quarterly. 
Journal, many years ago, giving a brief description of the country 
as far as the Gascoyne river in lat. 25°8., together with some 
diagrammatic sections, which show a belt of sedimentary rocks 
between the sea and the crystalline plateau forming the interior of 
the country. This belt of sedimentary rocks widens materially 
towards the north, being about 90 miles across on the parallel of 
the Gascoyne river. Amongst the rock-specimens in the Forrest 
collection are crystalline schists, &c., in which white mica and 
quartz are the most prominent minerals; and it is evidently from 
the degradation of masses of this class that the arenaceous rocks 
containing the fossils were derived. No limestone has been sent; 
but where the grits are largely charged with fragments of Encrinites, 
Polyzoa, &c. there is a proportionate increase of calcareous matter. 
No specimens of coal or of recognizable plants were forwarded. 
The fossils chiefly occur in “ Fossil range,” which runs nearly 
N.N.W. for over 100 miles; they present a thoroughly Carboniferous 
(marine) facies, several of the species being identical with or closely 
allied to well-known Carboniferous Limestone forms. Out of more 
than 20 species there is only one (a Pachypora, allied to P. cervi- 
cornis) which could be regarded as Devonian. Corals, crinoidal 
stems, Polyzoa, Brachiopoda, and two large species of Aviculopecten 
make up the list. In the Appendix some of these were described. 
The corals are chiefly represented by Amplewus and Stenopora ; 
whilst amongst the Polyzoa are two species of the very curious 
American genus Hvactinopora, only known hitherto from the Lower 
Carboniferous rocks of Lllinois. The ubiquitous Fenestella plebera 
is extremely abundant.

Ir is not often that we feel called upon to notice a penny book ; 
but the little treatise of which we have given the title above strikes 
us as so good a work of its kind as to deserve a tew words of 
welcome. Mr. Woodward, as will be seen from the title of his 
little book, has set before him a very modest purpose; but he has 
stuck to it in the most praiseworthy manner, and in consequence 
has succeeded in producing what cannot but prove a most useful 
manual for beginners in shell-collecting. He tells his readers how 
to make a cheap cabinet for the reception of their collections, then 
how to collect the shells to put into it, how to prepare and mount 
them when obtained, and, lastly, how to classify and arrange their
