G. M. Thomson. — O71 New Zealand Crustacea. 235 



5-jointed, shorter than the last joint of the peduncle. Mandibular append- 

 age very slender, 3-jointed. First gnathopoda with the basal joints slender; 

 meros very small ; proximal end of the carpus flattened into a circular disc, 

 distal end tapering to an acute point, produced to about two-thirds the 

 length of the propodos, which is elongated and without any distinct palm ; 

 dactylos curved, about one-third as long as the propodos, finely serrated on 

 its inner margin. Second gnathopoda with the carpus produced to two- 

 thirds the length of the propodos, ending in a curved spine and bearing 

 numerous hairs ; propodos large, oval, its lower margin with numerous 

 dentations, a tuft of hairs at its upper extremity ; dactylos curved, half as 

 long as the propodos. Pereiopoda slender ; three last pairs with wide basa, 

 which are crenated on their posterior margins. Three posterior pairs of 

 pleopoda with narrow-lanceolate, nearly smooth rami. Telson narrow, 

 tapering to a sub-acute, entire apex. Integument rather thin, semi- 

 transparent. Length 0"35 inch. 



Hah. Two specimens were obtained, one from Port Pegasus (5 fathoms), 

 and a smaller one in Paterson Inlet (in about 10 fathoms). 



I have named this species after Mr. Charles Traill, of Cooper Island, 

 Paterson Inlet, a gentleman who has aided much in the investigation of the 

 Fauna and Flora of Stewart Island. 



G-enus Moera, Leach. 



Long and slender. Superior antennas appendiculate, much longer than 

 the inferior. Inferior antennae a little posterior to the superior, having the 

 peduncle much longer than the flagellum, and not reaching to the extremity of 

 the peduncle of the superior. Oral appendages receding. Mandibles having 

 an appendage. Four anterior coxae not so deep as their respective segments ; 

 three posterior not much shorter than the preceding. Gnathopoda unequal ; 

 second pair much the larger. Pereiopoda slender, subequal. Posterior pair 

 of pleopoda biramous, subfoliaceous. Telson double.

" Slender; cox£e narrow. Superior antennae half as long as the body; 

 base a little longer than the flagellum ; first and second joints long, sub- 

 equal, third very short ; flagellum pubescent; sette longer than articuli, and 

 hardly divaricate ; secondary appendage rather longer than half the flagellum. 

 Inferior antenna shorter ; base shorter than base of superior pair ; flagellum 

 very short. First pair of gnathopoda quite small ; propodos oblong, hirsute 

 below, narrower at base ; propodos of second pair equal, very large, sub- 

 quadrate; apex transverse, defined by a spiniform acute immoveable tooth ; 

 palm tri-dentate, teeth prominent ; dactylos hardly longer than palm. 

 Two posterior pahs of pereiopoda subequal, the fifth a little the shorter, the 

 joints at their posterior apices densely hirsute ; other setse short."
