A. Miliie-Edwards's " Benthesicymus Bartktii (Smith) ? " from the 

 Travailleur dredgings (figured ia the Eecueil de Figures de Crustac^s 

 nouveaux ou peu coiinns, April, 1883), if correctly figured, is certainly 

 specifically different from my species, and probably belongs to a differ- 

 ent genus, perhaps to Bate's Benthesicymus. In Milue-EdwanLs's species, 

 the dactylus of the second gnathopod is figured as slender, and styli- 

 form, and the dactyli of the fourth and fifth pera^opods are represented 

 as very long, slender, multiarticulate, and flagelliform. It is possible 

 tliat the single dactylus of a fifth perseopod of Benthcecetes Bartletti 

 which I have been able to examine may be a reproduced and abnormal 

 segment, and that the fourth and fifth peraeopods are similar to those 

 in Milne-Edwards's species, but I think this not at all probable. 



Benthesicymus? carinatus, sp. nov.
