Cururox.—On New Zealand Sessile-eyed Crustacea, 255 
second gnathopod ; both are wanting in P. cylindricus ; in Mr. Kirk's speci- 
mens the one at the distal end is present, but the proximal end is simply 
rounded as in P. cylindricus. In Mr. Kirk's specimens, as in some of mine, 
the outer branch of the last pleopod terminates in more than three teeth, 
four, five, and even six are found. P. cylindricus is described as terminating 
“in three hooks.” I do not, however, attach any importance to this, for it 
is evidently a character that varies with the size and age of the specimen, 
The general description of this species will be as follows :— 
Podocerus longimanus. PI. xvii., fig. 2, a to e. 
Podocerus cylindricus, Kirk. Trans. N.Z. Inst., vol. xi., p. 402. (Not Say.). 
Wyvillea longimanus, Haswell. Proc. Linn. Soc. N.S.W., vol. iv., p. 336, 
pl. 22, fig. 7. 
Male.—Eyes round, Superior antenne about as long as the cephalon 
and first three segments of the pereion ; first segment of the peduncle short, 
thick ; second and third much slenderer, second slightly longer than the 
third ; secondary appendage slender, 2-jointed, nearly one-fourth the length 
of flagellum ; flagellum rather longer than last joint of peduncle. Inferior 
antenna about half the length of the body, stout, subpediform, peduncle 
equal in length to the superior antenna ; flagellum as long as the last joint 
of peduncle, armed towards the end with stout curved spines. Both 
antenne having the inferior margins fringed with long sete. 
First pair of gnathopoda small; carpus nearly as broad as propodos and 
about half as long; propodos ovoid with two stout sete at the point where 
the dactylos impinges, palm with a few sete ; dactylos with concave margin 
more or less serrated, almost pectinated in large well-developed specimens. 
_ Second gnathopoda very large, carpus very short, propodos longer than the 
cephalon and first two segments of the pereion, cylindrical, sides parallel, 
curved, a blunt tooth at the distal end of concave margin, proximal end 
rounded or produced into blunt tooth; palm broad, more or less thickly 
fringed with fine sete. Dactylos nearly as long as the propodos, concave 
border smooth, with an enlargement near the base. Posterior pleopoda 
with the peduncle elongated, narrowing slightly towards the end, upper 
margin with a few short sete; rami very short, inner styliform, outer 
ending in from 3 to 6 upturned tooth. Telson conical, blunt, 
Female.—Differs from the above in having the concave margin of finger 
of first gnathopod only slightly roughened, not serrated. Second gnathopod 
not larger than the first, similar to it in shape, but with the carpus shorter, 
C _ and propodos rather more narrowed distally. Dactylos with basal half of 
concave margin roughened, extremity smooth. | | 
Colour, pale yellow, more or less thickly covered with black dots and 
markings.
