triangular ; propodos irregularly ovoid, palm oblique, excavate, defined b}- 

 a triangular tootb, and armed with another of similar form near the distal 

 end. Two anterior pairs of pereiopoda subequal ; three posterior pairs 

 with the basa oblong twice as long as broad, the other joints very broad, 

 the dactylos very stout; fourth pair smaller than the fifth and sixth. 

 Eami of fourth pair of pleopoda as long as the protopodite ; those of the 

 fifth pair shorter ; those of sixth pair very short, conical, armed with a few 

 straight seta?. Telson simple, conical, compressed. Colour brown. Length, 

 ■wu inch." 



Hab. Lyttelton Harbour ; Timaru. 



This species is moderately common at Lyttelton Harbour ; Mr. Has- 

 well's specimens are from Port Jackson. The female differs from the male 

 in the form of the second gnathopoda. The first gnathopoda are like those 

 of male, and are shown in pi. II., fig. 5 a. They are very hairy, and at 

 the inferior edge of the palm are two stout seta3. The second gnathopoda 

 of female are much smaller than those of the male, the carpus is sub- 

 triangular and larger than the carpus in the second gnathopoda of male, it 

 has its distal and inferior borders setose ; propodos only slightly broader 

 than the carpus, long ovate, with small tufts of setae on the two sides and 

 on the middle, palm oblique imperfectly defined by a stout seta on each side 

 at the end of the dactylos. 



Genus Moera. 

 Moera incerta, sp. nov. PI. III., fig. 3. 



None of the segments of pleon or pereion produced into teeth. Coxae 

 shallower than their respective segments. Basal joint of upper antenna 

 stout, narrowing distally, second joint only slightly longer than the first, 

 third joint short ; flagellum shorter than peduncle, about as long as the 

 basal joint and half the second ; secondary appendage rather more than 

 half as long as the flagellum ; setae on the antenna short and very fine. 

 Lower antenna shorter than the upper, slender ; peduncle as long as that 

 of upper antenna, last joint of peduncle slightly shorter than the preceding 

 joint, flagellum short, not quite so long as the last joint of the peduncle, 

 setae short and delicate. First pair of gnathopoda having the carpus about 

 as large as the propodos ; its outer edge with a shallow notch towards the 

 distal end, inner edge densely fringed with setae, small tufts of setae 

 scattered over the joint; propodos ovate, not very hairy, palm slightly 

 convex, fringed with short setae, imperfectly defined by one or two 

 stout short setae; dactylos slender acute, with one or two long setae at its 

 base. Second pair of gnathopoda very large, carpus rather small sub- 

 triangular, propodos very large, subrectangular, slightly narrowed at 

 the base, inner margin slightly sinuous, with a few small tufts of seite
