the propodite, tapering. Legs of the 5th pair, in the male, sub- 

 cheliform. 



Abclomiual appendages of the Ist somite, in the male, slender, 

 uniramous, short. Those of the four followiug pairs biramous, the 

 rami foliaceous, the exopodite broader and shorter than the endo- 

 podite that is furnished with a stylambljs. 



7. Meticonaxius monodon n. g. n. sp. 



Station 5. Lat. T 46' S., long. 114° 30'.5. Depth 330 M. 



Carapace smooth, glabrous. Rostrum sharp, reaching just beyond 

 the Ist joint of anteunular peduncle. Abdomen hairy, especially 

 the 3rd — 5th somites, that are clothed with plumose, flexible, 

 silk-like hairs, each hair inserted in a circular, circumvallated pit. 



Sixth somite quadrate, a little shorter and less broad than the 

 2nd, that is slightly longer than the rest; pleura unarmed, rouuded. 

 Telson a little shorter than the 6th somite and, like the caudal

Anophtlialmaxius n. g. 



A new genus of the family Axiidae, chiefly characterized by 

 the transformation of the eyepeduucles in two quadrangular plates, 

 that are probably coalesced, not only with one another in the 

 middle line, but also with the basal joints of the antennulary 

 peduncles; their upper surface is punctate and they are probably 

 anteriorly emarginate. No tracé of eyes at all. ') 



1) Though in the single specimen, on wiiich this genus was founded, the rostrum 

 was rather badly damaged, the quadrangular plates appear to be uninjured and present 

 apparently still their natural characters.
