placed it in the order of pcecilopoda. I remark, nevertheless,

 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 Nebalise, 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

 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.

 single eye, situated in the middle of the forehead, between the 

 upper antennge. Such are

So accurately observed by the elder Jurine 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
