in this species is long, very much narrowed distally ; the telson is 
divided beyond the centre. 
The following accounts of Talorchestia tumida and Amphithopsis 
cerulea, from New Zealand, were sent along with the specimens by 
Mr. G. M. Thomson, their discoverer. His remark that in 
Amphithopsis (Pherusa?) cerulea the 4th coxa is broader than the 
preceding three together, applies to the appearance in the undis- 
sected specimen, not to the coxee or side-plates when drawn apart. 
“©2, TALORCHESTIA TUMIDA, 0. Sp. 
General form of body, when seen from above, much inflated. Eyes 
large (in living specimen of a turquoise-blue colour). 
Anterior antenne very short, reaching a little past the extremity 
of the penultimate joint of the peduncle of the posterior pair ; 
flagellum 7-8-jointed, subequal with peduncle. Posterior antenne 
as long as cephalon and first two segments of pereion, last joint of 
peduncle much the longest ; flagellum 12-14-jointed, slightly shorter 
than peduncle. 
Males apparently of two forms :— 
First Form.—First gnathopod with the propodos somewhat 
curved, its inferior margin distally produced and rounded ; dactylos 
curved and much longer than the palm ; carpus and propodos with 
numerous spines. Second gnathopod with the carpus small and 
triangular ; propodos ovoid and smooth, palm very oblique and 
furnished with two rows of minute teeth; dactylos two thirds as 
long as propodos, with its point lying over the edge of the palm. 
Third pereiopod short, fourth and fifth very long, former with the 
bases not dilated. 
Second Form.—Second gnathopod with the propodos broadening 
towards the distal margin, palm nearly transverse with a blunt tooth 
between the middle and hinge of the dactylos ; latter furnished with 
a large tooth impinging outside of the tooth of the palm. Third 
and fifth pereiopoda normal: fourth with the the carpus nearly 
quadrate and broadly dilated. 
Telson nearly as broad as long, quite round at the apex and 
fringed above with a submarginal row of minute spines. Colour, 
when alive, ivory-white. 
Hab. In sandbanks, Purakanui near Dunedin, among roots of 
littoral plants, many yards from high-water mark. Each specimen 
inhabiting a hole of its own. When taken out they leap with great 
vigour.

Length about 5 mm. Superior antenne about 4 mm. long, and 
considerably longer than the inferior ; last joint of the peduncle with 
a secondary appendage consisting of a single joint and a terminal 
seta; flagellum about three times as long as peduncle and very-many-
