SOME NEW-ZEALAND SCHIZOPODA. 485 



maxillse liave tlie terminal joint broadly obovate, and furnished 

 ■witb numerous strong setae on the outer margin. The inaxilU- 

 pedes and gnathopods present no very distinctive features. 



The legs are rather slender in structure, the propodos ending 

 in a tuft of fine setae ; the exopodites are all well-developed, with 

 a broad basal joint, bearing a ten- or eleven-jointed setose branch 

 (fig. 12). 



The marsupial 2^ ouch in the female is formed of three pairs of 

 lamellae, the anterior of which are very small, and the posterior 

 very large. 



The p?(?o/>o(?a are rudimentary in the females. In the males 

 the first pair has the inner ramus very short and one-jointed, 

 obtuse at its apex, and with a lateral process produced across the 

 long outer ramus ; the latter is normally six-jointed (figs. 13 and 

 14). The succeeding pairs have both rami well-developed, 

 subequal in length and natatory, but the inner is always furnished 

 with a process near its base which is produced more or less across 

 the outer branch (fig. 15). Telson short, only about half as long 

 as broad, slightly narrowing at the sides, which are furnished 

 with about twelve spines including the terminal one; the apex 

 is deeply cleft, the sides of the notch being furnished with fine 

 close-set pectinate spines and the centre defined by two long 

 plumose setae (fig. 17). 



The uropods have the outer plate long and slender, somewhat 

 obliquely truncate at the apex ; the inner is about two-thirds as 

 long as the outer, broadly lanceolate in form, and tapering to an 

 obtuse apex, its inner margin has numerous spines between the 

 setae ; both plates are densely setose on both margins (fig. 16). 



Length of the adult females, 10-16 mm.
