Two young apparently irew Crustacea, one living among Balanus sulcatUSy 
the other among Atwtifa vulgaris, are described by E. Hesse in several 
stages of their development, Ann. Sc. Nat. xvi. pp. 121-162, pi. 2. figs. 9-27, 
and pi. 3. figs. 1-26. He poiirtp put, some resemblances between them and 
the younger states of the Oirripeds among, which they live, and thinks that 
they may belong to the division of Isopoda sedentaria {Bopyridc^, forming a 
link between this division and the Oirripeds. As the full-grown animals 
are not yet known, he does not give a name to them, nor anythiug lijco a 
generic definition. . • .

The monograph of British Entomostraca by Norman and 
Brady is introduced by a short critical review of the memoirs 
and works published since Dr. Baird^s ^ Natural History of the 
British Entomostraca.^ Then the authors proceed to the 
description of genera and species. Only fifteen of the thirty-thre^ 
species described in this memoir as British are found in Dr. 
Baird^s work; twenty-eight of them have been found by the 
authors themselves within the counties of Northumberland and 
Durham; one species is (^uite new. The system adopted by 
them is that of G. O. Sars. 
The following, are acknowledged as British species, fully 
described, and most of them illustrated by very good figures : —
