CiiiiiTON. — Crustacea of the Kennodec Inlands. 563 



with Miss Rathbim's description in having no accessory spines on the 

 rostrum ; the siiperocular eave thick, projecting at its posterior angle into 

 a sharp tooth ; the post-ocular spine simple ; in having two spines on the 

 posterior margin of the carapace ; and in most of the other characters. 

 The carapace, however, appears smoother than in Miss Rathbun's speci- 

 mens, and in the central part the spines mentioned by her are either absent 

 altogether or indicated only by slight tubercles ; the two cardiac spines 

 and the intestinal spine are thus indicated in some specimens, but there 

 seems no indication whatever of the three gastric spines. My largest speci- 

 men has the carapace from the tip of the rostral spines to the extremity 

 of the spines on the posterior margin 17 mm. in length, and the width with- 

 out spines 10 mm., thus corresponding with the dimensions given by Miss 

 Rathbun. Her specimens are from the Hawaiian Islands.

Numerous specimens taken from the stomach of a kahawai fish {Arripis 

 trutta Forster) caught at Denham Bay, 8th September, 1908. 



The species is very widely distributed, especially in southern seas. 



Mr. Oliver states that during September and October the surface waters 

 of the bay were literally full of shrimps and shoals of kahawai, and that 

 heaps of shrimps were washed up on the beach. Humpback whales ap- 

 peared in considerable numbers, and probably fed on these shrimps. 



These " shrimps " may have been of various kinds, but the present 

 species and the Hyperids mentioned below are the only pelagic forms in 

 the collection that are likely to have occurred in great numbers. 



Order AMPHIPODA.

One small egg-bearing female from Coral Bay, Sunday Island. 



This specimen seems to be quite the same as specimens from New Zea- 

 land that I have referred to this species. The telson has the sides con- 

 siderably upturned, and bears one long and one short plumose seta on each 

 margin ; the posterior margin has a rather deep though fairly wide indenta- 

 tion, each portion ending posteriorly in two or three stout setae. Third 

 uropod of normal shape for the species ; the inner ramus very small.

I have one imperfect specimen from Sunday Island which from its 

 size and other characters certainly belongs to this species. The body is 

 35 mm. in length, and the shape of the different segments and of the side 

 plates and the dorsal depression on pleon segments 3 and 4 agrees well wdth
