"With 



The recently-published figures (Recueil de figures de Crustac^s nou- 

 veaux ou peu conn us) show that my Eiimiersiais apparently synonymous 

 with A. Milue-Edwards's Nematocarcinus (Ann. Sci. Nat. Zool., VI, ix, 

 No. 4, p. 14, 1881), although the type si)ecies of the two genera are evi- 

 dently distinct. The genus resembles PandaUis in the external form 

 of the carajjax and abdomen, agrees with it essentially in the structure 

 of the oral appendages, and has the same number and arrangement of 

 branchiae and epipods. The form of the first and second perseopods, 

 and the presence of exopods at the bases of the first four pairs of per- 

 aeopods are more like Acanthephyra than Pandalus, but the peraeopods 

 are all exceedingly long and slender, and the three last pairs are very 

 nearly alike and peculiarly modified at the extremities. The mandibles, 

 though essentially as in Pandalus, are stouter and have larger molar 

 processes, while the ventral processes are very thin, more expanded, 

 and with broader serrate tii)8, thus approaching somewhat to the struct-
