Body carrying a few minute tubercles, the most conspicuous being the 
one on the cephalon, and the most constant those upon the posterior seg- 
ments of the pereion. First segment of the pereion long; second scarcely 
longer than the first; the three succeeding rather shorter, sub-equal. 
Superior antenne not half the length of the animal; inferior scarcely 
reaching beyond the second joint of the peduncle of the superior. Second 
pair of gnathopoda articulating with the pereion posteriorly to the centre 
of the second segment; propodos long-ovate, palm defined by one and 
armed with two teeth, the anterior one being often less perfectly defined 
than the posterior. Three posterior pairs of pereiopoda having the propoda 
with the anterior margin excavate; the part against which the closed 
dactylos impinges armed with two stiff corrugated spines. 
Hab: Cook Strait. 
The only examples of the genus Squilla yet recorded from New Zealand 
are S. nepa, Cat. N.Z. Crust., p. 89, and S. armata, M. Edw., Trans. N.Z. 
Inst., IX., p. 474. It is with very great pleasure I now add a third. In 
addition to the specimen exhibited, which was obtained at the Chatham 
Islands, another, unfortunately mutilated, was secured by H. B. Kirk while 
on a visit to Kapiti.

E SS Rostral plate semi-oval, and pointed at its 
V distal extremity. Carapace retracted in front,

/l (1M antero-lateral angles rounded and slightly 
produced forward; large prehensile limbs wi 
terminal joint as long as preceding one, and

ZN terminal segment with six marginal spines,

This species is easily distinguished by the 
absence of carine on the abdomen, and by 
the absence of the antero-lateral spines of the 
carapace,

External antenne extremely minute, inserted in the inner canthus of 
the orbit; internal antenne lying in oblique fosse, which are entirely 
separated by a small process of the epistome, and concealed by the front ; 
external pedipalps elongato-triangular, reaching forward to the margin of
