Basal scale of antennae like that of P. j;Za«z/rons, but not 

 narrowing so abruptly, and extending only to the end of the ros- 

 trum. Carapace nearly cylindrical, greatest breadth generally 

 a little less than one-fourth the length, of the same width 

 throughout whole length of the branchiostegite, or bulging in 

 centre ; carapace nearly smooth, or with spines along the cer- 

 vical groove and on the branchiostegite and elsewhere, spines 

 usually more numerous than in P. planifrons ; two spines on 

 each side of the base of the rostrum. Eostrum elongate, 

 triangular, sometimes depressed, margins raised and usually 

 with four teeth on each side, under surface keeled and usually 

 with two teeth. Median ridge behind rostrum arising on level 

 with the first of the two spines at "the base of the rostrum and 

 extending backwards three-fourths of the distance to the cervi- 

 cal groove. Anterior portion of epistoma flat and triangular, 

 or narrow, ending anteriorly in a sharp spine. Great claw^s 

 stout, propodos usually compressed, one and a half times as 

 long as the carpus and nearly twice as long as broad, both 

 sides covered with small tufts of hair and with stout spines 

 arranged chiefly in longitudinal row^s. Pleura of abdominal 

 segments usually rounded below, anterior edge longer than 

 the posterior, which curves forward, both edges fringed with 

 setae. 



Length of largest specimen, 6-3in. 



Habitat. South Island generally, excepting north-western 

 portion ; Stewart Island.
