that given for this species. The dorsal carina is well marked ; it is pretty 

 distinct on segments 4-7 of the peraeon and 1-4 of the pleon, and there 

 is some indication even on the third segment of the peraeon. The speci- 

 men was evidently much decayed before it was collected, and nearly all 

 the appendages are wanting ; the greater part, however, of the second 

 gnathopods is still present, and agrees well with the description given by 

 other authors. The same is also true of the mouth parts, so far as I have 

 been able to examine them. 



The species is well known in northern seas, and has also been taken 

 in various places in the Atlantic and near Cape Horn. Its occurrence at 

 the Kermaclecs is interesting, and shows that it probably distributed widely 

 in southern seas. 



It is celebrated as being one of the largest of the Amphipoda, the length 

 sometimes being as much as 90 mm.

Moera mastersii Stebbing, Das Tierreich Amphip., p. 439, 1906 (with 

 synonymy). 



Two specimens from Coral Bay, Sunday Island. 



In colour, shape of the body, eyes, and appendages these specimens 

 agree closely with the description given by Stebbing. 



The species is known from Torres Strait and Port Jackson. 



Melita inaequistylis (Dana). 



Melita inaequistylis Chilton, Subant. Islands N.Z.. p. 630, 1909 (with

One male specimen taken at low-water mark at Coral Bay, Sunday 

 Island, by Mr. T. Iredale. 



This specimen has the fourth pleon segment without teeth, the fifth 

 with 2 or 3 small teeth, and the gnathopods show the characters usually 

 present in adult specimens of this species from the main islands of New 

 Zealand.

? Melita palmata Stebbing, Das Tierreich Amphip., p. 425, 1906 (with 

 synonymy). 



Two males and one female from Coral Bay, Sunday Island, appear to 

 belong to this species. 



It is only with much hesitation that I refer these specimens to tliis species, 

 which, according to Stebbing, is known only from the North Atlantic and 

 surrounding seas. In all three specimens the fourth pleon segment is pro- 

 duced dorsally to a compressed tooth, and segment 5 bears two small 

 denticles, each with a bristle at the base, exactly as described by Stebbing 

 for M. palmata, and the resemblance is very close in practically all the 

 other characters, except that the lower antenna is nearly as long as the 

 upper, and the secondary appendage of the latter consists of more than 

 two joints — three in one specimen, and four in the others. The first gnatho- 

 pod of the male is not specially modified, but has the propod and dactyl 

 of normal shape, as in the female. The second gnathopod has the propod 

 greatly enlarged and widened distally, but not produced into the rounded 

 lobe shown in Sars's figure ; the palm is moderately well defined, and is.
