antenna springing from underneath the base of the inner, half as long again, 
and slender. Segments of the thorax directed backwards at their postero- 
lateral margins; first segment broader than others; succeeding segments 
subequal, each with a flattened granulated ridge on its posterior margin, 
giving the back a transversely grooved appearance. First segment of 
abdomen produced posteriorly into a flattened truncate expansion, with a- 
slight median indentation; last segment placed almost underneath, the 
former, triangular in shape, with a pyramidal tubercle on each side, its apex 
united to the internal rami of the caudal lamelle. External rami thick, 
angular, and two-jointed. Legs fringed on their inferior margins with 
short, thick hair, Colour dark brown, Length *6 inch,

Talitrus ? nove-zealandie, Dana, ( Orchestoidea ? novi-zealandie ). 
This species is certainly the female of Talorchestia quoyana, and therefore 
ought to disappear from the catalogue. I have repeatedly found the two 
together, and in fact have seldom collected the one without the other. 
The males of the Talitrus, and the females of the Talorchestia, have never 
yet been described as such.

This genus is defined as follows :—‘ Superior and inferior antennm 
subequal, scarcely longer than the cephalon. The rest of the animal 
generally resembling Allorchestes, except the telson, which is deeply cleft.” 
It in reality includes all those Crustaceans which would range under 
Allorchestes, but for the cleft telson. 
9. Nicea nova-zealandie, nov. sp. Fig. B.1. 
Eyes reniform. Inferior antenna about one-fourth as long as body; 
flagellum slightly longer than base, with 18 or 14 articulations, which are 
minutely setose. Superior antenne reaching to middle of flagellum of 
inferior ; flagellum 14.jointed. Gnathopoda of first pair small; carpus 
produced inferiorly to a rounded lobe, furnished with a bundle of sete ; 
propodos sub-quadrate, inferior margin excavate about the middle and 
furnished with a bunch of setm, palm transverse, defined by two stout 
spines, setose; a bunch of set at the articulation of the dactylos. Propo- 
dos of second gnathopoda large, ovate (almost pyriform) in male, palm very 
oblique, occupying nearly all the under surface, furnished with a double 
__ Tow of stiff setæ, and defined by two stout spines; dactylos long, slender, aS
