5-jointed, shorter than the last joint of the peduncle. Mandibular append- 
age very slender, 8-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. 
Hab. 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. 
Genus Moera, Leach. 
Long and slender. Superior antenne appendiculate, much longer than 
the inferior. Inferior antenne 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 nppeiidagts receding. Mandibles having 
an appendage. Four anterior coxe Sut 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 narrow. Superior antenne half as long as the body; 
base a little longer than the flagellum; first and second joints long, sub- 
equal, third very short; flagellum pabessatt; sete longer than articuli, and 
hardly divaricate ; 3 secondary app tl ger than half the flagellum. 
Inferior antenne 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 pairs of pereiopoda subequal, the fifth a little the shorter, the 
joints at their posterior apices densely hirsute; other sete ware
