A. Milne-Ed wards's " Bentliesicymus Bartletti (Smith) ? " from the 

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

 nouveaux on peu counus, 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 Milne-Edwards's species, 

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

 form, and the dactyli of the fourth and fifth perseopods are represented 

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

 that 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 perteopods are similar to those 

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