 tralia, New Zealand, and Antipodes Island.

A small female specimen was collected at Antipodes Island by Dr. L. Cockayne 

 in July, 1903. 



I do not feel certain about the systematic position of this species, but pending 

 further investigation I leave it under the Gammaridae, where Stebbing has placed it.

Several specimens from Carnley Harbour, Auckland Islands (Professor W. B. 

 Benham). 



This species is widely distributed in New Zealand, where it is met with both 

 on the open coast and also in lagoons and estuaries where the water may at times be 

 quite fresh. It is readily recognised both by the peculiar characters of the gnathopods 

 of the male and also by the colour, which is either slaty or greenish-brown, and remains 

 unchanged for a long time in spirit. Mr. Stebbing, in " Das Tierreich Amphipoda," 

 points out that Dana's and Thomson's statements with regard to this species are in 

 many respects contradictory. This, however, is merely due to the fact that Dana 

 described the species as being without an accessory appendage to the first antenna, 

 and to other errors in his description and figures. In 1904 Mr. A. 0. Walker recorded 

 this species from Ceylon, though pointing out one or two respects in which his speci- 

 mens differed from Dana's description, the chief being that the first and second 

 peraeopods were as long as the last two pairs, while in Dana's description and figure 

 the last two are much the longer ; Mr. Walker's specimens were doubtless immature
