in complete agreement with Mr. Stebbing's description ; and the same is true with 

 regard to the other parts of the body and appendages, so far as they can be made out. 



The species appears to be very closely related to P. bassi, Stebbing, to which 

 I have referred specimens taken with a surface-net in Otago Harbour, and I should 

 not be surprised if the two species prove afterwards to be identical. According to 

 Stebbing, they differ in many points, and the gnathopods alone suffice to distinguish 

 them ; his description of P. bassi is, however, taken from a single male specimen, 

 and if I am right in referring my New Zealand specimens to this species its gnathopods 

 are hardly so distinct from those of P. kergueleni as shown in Stebbing's figure. 

 However, the species in this family are so difficult to distinguish that I prefer to leave 

 the decision of this point over for further investigation. 



P. kergueleni was taken by the " Challenger " in Cumberland Bay, in Kerguelen 

 Island, and Mr. Stebbing doubtfully referred to this species a specimen from Marion 

 Island. 



Genus Harpinia, Boeck, 1871. 



Distribution. — Widely distributed in northern and southern seas. 



Harpinia obtusifrons, Stebbing.

Numerous specimens were dredged in 8 fathoms in Perseverance Harbour, 

 Campbell Island — one male with long second antennae and plumose third uropods, 

 many females with short second antennae and third uropods nearly naked. The 

 type specimens are from Kerguelen Island (55-220 m.), and Mr. Walker records 

 the species from the " Discovery " winter quarters in McMurdo Strait. 



This species has not been hitherto recorded from New Zealand, having probably 

 been confused with other species of the family ; but I have numerous specimens taken 

 in Otago Harbour with surface-net, others from Lyttelton Harbour (4 fathoms, 

 H. Suter), and in Mr. G. M. Thomson's collection there are specimens from the Bay 

 of Islands. These specimens all agree so closely with one another, and also with 

 Mr. Stebbing's descriptions and figures of the " Challenger " specimens, that I have 

 no doubt they are specifically identical ; they differ, however, in the following 

 points from the characters of the genus Harpinia as given by Stebbing in " Das 

 Tierreich Amphipoda " : The eyes are present and well marked, large, oval, black ; 

 the second antenna in the male has a long flagellum, and bears calceoli on the 

 terminal joints of the peduncle and also on the flagellum ; the third uropods in 

 the male have the rami plumose,
