Paris Basin in such a manner that with the type specimens, or good 
figures and descriptions before us, we should stand a reasonable 
chance of correctly determining a species. 
The Royal Malacological Society of Belgium is to be congratulated 
on publishing such an extensive and important work ; it will not be 
out of place, however, to mention that the author has been put to 
considerable expense in the matter, and the ‘‘Catalogue” is now 
sold in separate form. 
The value of M. Cossmann’s book lies in the critical manner in 
which he has dealt with the more or less fragmentary work of his 
predecessors, and in the careful and erudite manner in which he 
has modernized his subject. That some alterations will become 
necessary in overhauling new material is only to be expected, and 
new species will, in course of time, be added to the fauna, whilst 
the systematic positions of certain genera and species are yet capable 
of revision. As the author truly says, “ L’histoire paléontologique 
d'une région est, en effet, comme un livre toujours ouvert, sur les 
pages duquel on ne peut jamais inscrire le mot jin.” G. F. H.

\HE earlier finds in the Carboniferous rocks of Australia appeared 
to show the existence of a fauna very different from that 
co-existing in Europe. De Koninck, in his “ Récherches sur les 
fossiles paléoziques de la Nouvelle Galles du Sud,” combated that 
view, and went a little too far in assuming specific identity between 
Australian forms and similar ones either in Europe or North 
America. The general facies is indeed much the same, but the 
more accurate researches now being carried out by the accomplished 
author of the work before us show a parallelism rather, than an 
identity of development. One fact, however, on which De Koninck 
Jaid stress, is still prominent, and that is the large size of many of 
these Australian forms as compared with that of their allies in other 
parts of the world: the star-fish and sea-urchins, now first made 
known to us from Australia, are indeed prize specimens; among 
the crinoids, the genera Tribrachiocrinus and Phialocrinus are no 
less remarkable for magnitude than for structural peculiarities ; 
while a pygidium, on which the new species Phillipsia grandis is 
founded, ‘‘ must represent a Trilobite nearly three inches in length, 
an exceedingly large size for a Carboniferous form.” It is to be 
regretted that the conditions of sea-bottom that permitted such 
magnificent growth were not equally successful in the preserva- 
tion of the fossils, which are for the most part nothing but the 
impressions and cavities left after the disappearance of all calcareous 
matter, a state in which accurate study is extremely difficult. 
Of the animal-groups treated of in the present section of the 
Monograph, the most interesting are the Echinodermata. The
