that even in the famous work of Bloch, the figures of exotic fish 
are nearly all falsely coloured. We shall notice amongst the 
most interesting of the fish which our zoologists have brought 
home, the Squalus Philippi, of which there were only the jaws 
remarkable for their teeth spirally disposed; a new genus 
of ‘the family of eels, allied to Sphagebranchus; the Macolor, 
a singular fish, known only by the work of Renard, and which 
is of the genus Diacope. ‘Their collection will also have the 
merit of throwing light on the history of many fish, of which’ 
there were only descriptions without figures in the manuscripts 
of Commerson and of Forster. 
M. Lesson has shown no less discernment in painting the 
Mollusca after life. His figures will form a valuable conti- 
nuation to those given by Péron, and those which MM. Quoy 
and Gaimard have begun to publish. They represent more 
than 150 of these Mollusca or Zoophytes, of which a consi-' 
derable number are of the greatest beauty, either by the di-' 
versely ramified tentacula which they display, or by the bril- 
lianey or variety of their colours. 7 
Nevertheless, our naturalists have not neglected to preserve, 
as much as they were able, these Mollusca and Zoophytes.. If 
the contractions and discolorations which they undergo do’ 
not permit us to contemplate them in all their beauty, we have: 
at least an opportunity of observing the principal features of. 
their structure, and nearly all which is of import to be known 
of their interior organization. ; : 
The species thus preserved in spirits extend’ to more than 
fifty, of which twenty at least are entirely new to us: such are 
the Glaucus, the animal of the Concholepas, an Anatifa nearly’ 
without shell, which will make a new genus allied to Ofion. 
The shells amount to nearly 120 species, of which my are 
univalves; there is amongst others a Monorero, remarkable for" 
its great size and its long shape. Amongst the zoophytes’pre- 
served in spirits, a great number of Holothurie are to be re- 
marked for their size and the fine preservation of their colours.’ 
There are also several Echini and Asteri@, and an Isis Hip- 
puris still covered with its crust of polypes, which proves’ 
how near this coral approaches the gorgons. 
As we have already said, it is principally to M. Durville 
that we owe the rich collection of insects which form a part of 
the produce of this expedition. This skilful naval officer un- 
-dertook in a manner this labour by supererogation, and only 
deyoted himself to it in the moments of leisure which his prin- 
cipal duties left him. The present also which he has made 
of his insects to the Museum may be regarded as an act of 
pure generosity. On a former occasion, at the time of his
