M. Hesse communicates (Ann. des Sc. Nat. vol. iii.), in his fifth article on 
the new or rare Crustacea of the coast of France, a new genus and species : — 
Pleurocrypta galatece, p. 226, pi. iv. figs. 1-28, and a second notice I, c. 
vol. iv. p. 225. 
Male : Elongo-ovate. Pereion divided into seven subequal somites, of 
which the first is fused with the cephalon, defined by a strong line of de- 
marcation, and the last is attached to the pleon. Pleon triangular, consisting 
of a single piece. Pereiopoda terminating with a strong unguiculated and 
dentated dactylos. 
Female : Ovate, symmetrical, provided below with very long incubatory 
lamellas, covering entirely the inferior surface of the pereion. Pleon divided 
into six somites, each furnished with simple branchiae, pointed, and of unequal 
size. Pereiopoda formed of five joints (besides the coxa) , flat below and round 
above, and curved in the form of a hook. The propodos is larger than the 
rest, and curiously formed j it is round above, flat below, ampulliform, pre- 
senting at the extremity a little opening, which is contractile and bordered 
by a circle in relief, and on the other side some small denticulations. Length 
of male 0 001 millim., of female 0 007 millim. Taken beneath the carapace 
of Galathea squamosa. We have little doubt that this genus of Hesse is 
identical with that of Phryxus of Kroyer j and this present species appears 
to us strongly to resemble that which has been named Phryxus longihranchi- 
atus in the list of Crustacea published by the Dredging- Committee of the 
British Association. There are, however, some differences of detail, but which 
appear to be the result of the artist’s or engraver’s misconception of the struc- 
ture of the animal,.
