Chilton. — Additions to the Sew Zealand Crustacea. 81 



of a new genus, but, as I have only had two specimens, both of the same 

 species, I prefer to leave it under Mr. Haswell's genus for the present. 

 The details (fig. 1 a-d) were taken from a small specimen, and hence may 

 not represent quite accurately their form in more adult specimens. 



Genus Moera, Leach. 



(Cat. Amphip. Crust. Brit. Mus., p. 187.) 



Moera spinosa, Haswell. (Proc. Linn. Soc. N.S.W., iv., p. 268, pi. x., 



fig. 5 ; and Cat. Aust. Crust., p. 257.) 



" Posterior margin of the five anterior segments of the pleon armed 

 with a few acute teeth or spines ; fourth and fifth segments armed behind 

 with acute spines. Coxae much shallower than their respective segments. 

 Lateral plate of the third segment of the pleon serrated posteriorly. Eyes 

 long, oval. Superior antennae more than half the length of the body ; first 

 segment of peduncle as long as the cephalon and first segment of the 

 pereion ; second rather longer ; third very short ; flagellum as long as the 

 peduncle ; appendage nearly half as long as the flagellum. * 



" Inferior antenna? more than half as long as the superior pair ; third 

 segment of peduncle equal in length to the first segment of the pereion ; 

 fourth twice as long as the third, fifth as long as the cephalon ; flagellum 

 as long as the fifth segment of the peduncle. Anterior gnathopoda hairy, 

 carpus rather longer than the propodos ; the latter ovate ; palm oblique, 

 notched. Posterior gnathopoda with the propodos large, ovate, more 

 dilated in the male than in the female, palm defined by a strong acute 

 tooth, and armed in the male with two other prominent teeth. Two anterior 

 pairs of pereiopoda sub-equal. Third pair rather shorter than the fourth 

 and fifth ; basos of the three posterior pairs produced at its postero-distal 

 angle ; meros, carpus, and propodos serrated and hairy. Fifth pair of 

 pleopoda much shorter than the fourth. Sixth pair large, with a stout 

 protopodite and two broad-lanceolate rami, the latter serrated and armed 

 with setae. Telson double, each half ending in a sharp spine, and armed 

 with a bundle of stiff seta3. Length 8 lines." 



Hab. Auckland. 



Of this species I have two specimens, a male and a female, for which I 



have to thank Professor Hutton. He found them in a collection of Mollusca 



sent him from Auckland. Mr. Haswell's specimens were from Tasmania. 



In my specimen of the male the second gnathopod of the right side only 



has the two promiment teeth on the palm, and these are rather larger and 



more blunt at the end than those shown in Mr. Haswell's figure ; the 



second gnathopod of the left side is like those of the female, having the palm 



slightly convex, and without the two teeth. (See plate II., fig. 3a.) 



* In the Catalogue this is by an error printed " appendage nearly as long as the flagellum."
