placed it in the order of poecilopoda. I remark, nevertheless, 
that the feet, with the exception of the anterior ones, much 
resemble those of cyclops, and that the females also carry 
their eggs in two sacs, situated at the base of the tail, in the 
same manner as the latter. 
The second of these naturalists has just published, in the 
13th volume of the Annals of the Natural Sciences, some new 
researches on the Nebaliae, and the characters of those other 
new genera of Crustacea. Our labours on the animals of this 
class having been terminated at the moment when the memoir 
of M. Milne Edwards was communicated to the academy, 
and not having then the time to return to the subject, we have 
transferred our account of those genera, as well as of those 
established in the family of the Araneides by M. Savigny, 
and of some others recently introduced by Count Dejean, into 
that of the carnivorous coleoptera, in the supplement to this 
work. We shall also give them the characters of some other 
generic sections, established by MM. Guerin, Lepetier de 
St. Fargeau, and Serville. I could not have introduced them 
into my present researches, without hurrying an examina- 
tion, which should be so much the more careful, as it is more 
easy to multiply generic groups. 
The other lophyropa of our first division, in which the 
thorax, as well as in condylura, is divided into several seg- 
ments, the first of which is much the largest, present but a 
single eye, situated in the middle of the forehead, between the 
upper antennae. Such are

So accurately observed by the elder J urine and M. Ramdohr. 
Their body is more or less ovaliform, soft, or gelatinous, and 
is divided into two portions, one anterior, and composed of 
head and thorax, and the other posterior, or the tail. The
