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. Proe. Linn. Soc. N.S.W., vol. iv., p. 336, 

 pi. 22, fig. 7. 



Male. — Eyes round. Superior antennae 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 

 antennae having the inferior margins fringed with long setae. 



First pair of gnathopoda small ; carpus nearly as broad as propodos and 

 about half as long ; propodos ovoid with two stout setae at the point where 

 the dactylos impinges, palm with a few setae ; dactylos with concave margin 

 more or less serrated, almost pectinated in large well-developed specimens. 

 Second gnatbopoda 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 setae. Dactylos nearly as long as the propodos, concave 

 border smooth, with an enlargement near the base. Pos'terior pleopoda 

 with the peduncle elongated, narrowing slightly towards the end, upper 

 margin with a few short setae ; rami very short, inner styliform, outer 

 ending in from 3 to 6 upturned teeth. 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, 

 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.
