hairs. Inferior antennas slightly longer than the superior ; fourth and fifth 

 segments of the peduncle sub-equal ; flagellum half as long again as the 

 last segment of peduncle, of about twelve articuli ; both peduncle and 

 flagellum armed with slender hairs, which are longer on the former. An- 

 terior gnathopoda small, carpus slightly longer than propodos, thickly 

 fringed on inferior edge with serrated setae, propodos ovate, setose on both 

 margins, one or two stout setae at point of impingement of the end of dactylos. 

 Posterior gnathopoda very large ; meros with a pointed process at its infero- 

 distal angle ; carpus short, sub-triangular ; propodos about six times the 

 length of carpus, broad at the base, narrowing distally ; palm two-thirds of 

 the length of propodos, concave, with a low protuberance at its distal end, 

 armed with fasciculi of long hairs, defined by a spine-like tooth ; dactylos 

 nearly as long as the propodos, with an enlargement on its inner edge near 

 the base. Coxae of third segment of pereion extending anteriorly slightly 

 beyond the middle of coxa of second segment, anteroinferior angle rounded, 

 margin ornamented with small circular or elliptical markings at intervals. 

 Eami of posterior pleopoda scarcely larger than the others, lanceolate, armed 

 with a few bristles. Telson small, ending in two conical projections, each 

 bearing a stout seta. Colour, light olive with minute black dots. Length 

 J inch. 



Hab. Lyttelton Harbour. Also "Clark Island, Port Jackson ; amongst 

 seaweed " (Haswell). 



This species so closely resembles the preceding one in everything but 

 the second gnathopoda that it must be placed in the same genus. It has a 

 certain puzzling resemblance to Moera, to which it was referred by Mr. 

 Haswell, but differs in the broad setose appendage of the mandible, and in 

 the strong fringe of setaa on the antennaa (wherein it approaches Podocerus 

 and other allied genera), and in the telson. 



I do not know the female of this species as such. It probably would be 

 almost indistinguishable from that of Pamnania tyjnca. 



The mandibles and maxillipedes are almost exactly the same as those 

 figured for Paranania typica. When dissecting out the mouth-parts I came 

 across the part figured in pi. xxi., fig. 2 a. It evidently corresponds with 

 and closely resembles the "epistoma" of Cerajms abditus, figured by Bate 

 and Westwood in vol. i., p. 455, of the "British Sessile-eyed Crustacea." It 

 consists of a transversely elliptical portion, with short setaa pointing inwards 

 on the posterior margin, and, springing from this, a long pointed process.

Male. — First gnathopoda with the meros ending distally in an acute 

 point ; carpus considerably longer than the propodos ; inferior margin 

 thickly fringed with setas, chiefly arranged in short transverse rows ;
