618 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Crustacea. 



The species is now known from Kerguelen, Cape Wadsworth, Cape Adare, and 

 other localities in Victoria Land, and, although not hitherto recorded, it also occurs 

 in New Zealand, for I have specimens from Lyttelton Harbour. 



I have been able to compare these and the Snares specimen with specimens 

 in Mr. Thomson's collection from Cape Adare collected during the "Southern Cross " 

 Expedition, and can therefore feel confident about the identification.

I have two small specimens from Musgrave Harbour, Auckland Island, that I 

 think must be referred to this species. They agree with Mr. Walker's description in 

 having the " lateral angle of the head produced to the end of the first joint of the 

 upper antennae, the joint rounded," and in having the fourth segment of the pleon 

 neither dorsally depressed nor carinate and the posterior angle of the third segment 

 not produced into a curved tooth. The eye is somewhat large and reniform ; the 

 upper antenna has the first joint very broad and swollen, but the second joint is not 

 very short, being about two-thirds as long as the first but much more slender, the 

 third joint is short ; the flagellum is 11 -jointed, the accessory appendage small, 

 4-jointed. The second antenna is very slender, the last two joints of peduncle sub- 

 equal, flagellum 7-jointed. The first gnathopod agrees in general with Walker's 

 description, but has the palm somewhat more oblique and irregularly defined, with 

 stout setae, and, though the finger has a projection on the inner side, it is not so 

 deeply divided as shown in Walker's figure. In the third uropods the peduncle is 

 slightly produced at the upper distal angle into a subacute point. In other respects 

 the specimen seems to agree closely with the description given by Walker, the few 

 points of difference mentioned above being probably due to immaturity of my speci- 

 mens. The whole of the body is darkly pigmented, the pigment being unaltered by 

 the spirit. 



Walker's species was taken at Cape Adare; another species referred to this 

 genus by Stebbing, T. cicadoides (Stebbing), is found at Kerguelen Island, and is 

 perhaps not so different from the present species as might be imagined from a com- 

 parison of the descriptions given of the two species.

I have two imperfect specimens, dredged by Captain Bollons at the Snares, 

 in 50 fathoms, which must, I think, be referred to this species. The gnathopods are
