abundant in two rows on each side of the palm ; basos hollowed out in 

 front, so as to receive the upper side of the propodos ; meros acutely pro- 

 duced on its infero-posterior margin ; propodos articulating on the apper 

 margin of the carpus, oblong, that of the left side shghtly the larger, and 

 having the teeth more prominent on its upper margin ; palm extending 

 along the whole under-surface, with two or three denticulations ; dactylos 

 long, curved and smooth. Pereiopoda sub-equal, fifth pair the longest ; setse 

 numerous and strong, not exceeding the diameter of the articulations to 

 which they are attached. Telson conical, tipped with a few slender setse. 



The female differs from the male only in the greater width of the pereion, 

 and in having the second gnathopoda relatively smaller, rounder, and 

 wanting the plumose cilia. Length '25 inch. 



Hab. Dredged in Dunedin harbour in 4-5 fathoms, among Sertularise 

 and seaweeds. 



Genus Corophmm, Latreille. 



" Superior antennse small, situated close together in advance of and 

 above the inferior, having a multi-articulate flagellum. Inferior antenna 

 very large and powerful, subpediform ; flagellum not multi-articulate. First 

 pair of gnathopoda subchelate ; second pan not subeheliform. Posterior 

 pair of pleopoda very short, single -branched. Telson squamiform, simple."

*' AntemiEe equal in length, which is one-fourth that of the body ; supe- 

 rior antennae with four-articulate flagella ; inferior antenna very thick, with 

 minute terminal articuli. Posterior pan of pereiopoda rather long, with 

 long plumose setre along the edges of the basa. Colour yellowish. Eyes 

 black. Length J of an inch. 



Hab. " Japan." 



The above description is taken from the Brit. Mus. Catalogue, p. 282, 

 where it is quoted from the Proceedings of the Academy of Nat. Science, 

 Philadelphia, for 1855. Meagre as it is, there is little doubt that it is iden- 

 tical with the species obtained by me. I have therefore given a figure of the 

 animal, and a supplementary description, which applies only to the females. 



Body much broader than deep. Eyes small. Superior antenna with 

 the first joint stout, produced on its inferior inner margin into two stout 

 teeth ; second joint equal to it in length, slender ; third much shorter and 

 hardly distinguishable from the flagellum, which is five-jointed, and termi- 

 nated by a bunch of setae. Inferior antenna very strong, with a few strong 

 teeth on its inferior margin on the inside. First gnathopoda small ; basos 

 with two long set^ ; ischium, meros and carpus fringed with long setse ; 

 propodos rounded towards the extremity, with a convex palm fringed with
