terials and perfected what he had before learned. He has been at 
great pains: and expense in procuring the three or four varieties of 
the developement of each species, from its issue from the egg to its 
state of decrepitude, as well as those on which may depend the pro- 
-portionate size and the color. From these labors has resulted the 
- finest collection with which we are acquainted. Those species which 
are wanting, are'supplied by good colored figures. Aided by these 
materials, | M. Duclos has executed a complete and methodical des- 
cription, with a colored representation of all the species and principal 
varieties of the porcellanous shells now existing in the collections of 
central Europe. | He has considerably. increased the number of known 
species, especially in France, since he extends the\whole number of 
species to one hundred and forty two, of which seventy seven are 
from New Guinea, California, Scychelles, &c. Lastly; he has dis- 
tributed them into three very natural sections; the Alucitated or sleek 
kinds, the tuberculated and the striated. We hope that this great 
~ work may be connected with the materials which Quoy and Gainard 
_ have co d by their late circumnavigation, and which have brought 
ige a great number of species. The reporters condude 
that Duclos may, as soon as possible, be enabled to 
gratify the taste of amateurs by laying before them the result of his 
extensive and expensive labors, which they deem to be altogether 
worthy of the encouragement and approbation of the Academy.—

we Bone Caves in New Sotlend: —A ‘golleeaeia of fossil bones

‘They are found embedded*in a red ochreous cement which 
“occurs partially in crevices of the limestone rock, in’different parts of 
the interior of South Wales... The limestone ‘rests on granite, a0 
generally near or under trap rock. The bones are found in a brok- 
en state, as in caves’of a similar character in Europe, and. ie them 
they are of animals of’ very different kinds and sizes. 
It appears from the description, by Major Imrie, of the red pate 
ous cement, containing bones which occur at Gibraltar, and along 
the northern shore of the Mediterranean, that this breccia is of the 
same kind, both in situ, and character, and that its antiquity. ds
