1006 MR. I/. A. nOBRADAILE ON CRUSTACEANS [DeC. 13, 



supraorbital, auteunal, and hepatic spines, and with one in the 

 dorsal median line, some little distance behind the rostrum. The 

 pterygostomial angle is subrectangular. The slender Hagellura of 

 the iirst antenna of the present specimen is broken short on the 

 right side and, I think, also on the left. On the latter side it is as 

 long as the thicker flagellum, which is very stout and about equals 

 the peduncle in length. The scale of the second antenna extends 

 to the end of the rostrum, and the flagellum is about as long as 

 the body. 



The third maxilliped reaches the end of the penultimate joint of 

 the antennular peduncle. 



The wrist in the first pair of legs ends slightly beyond the 

 scale of the second anteuna and bears a spine on the inner side at 

 its distal end. The fingers are about equal to the palm. The 

 legs of the second pair are almost equal, and exceed those of the 

 first by nearly the whole length of the hand ; they are armed at 

 the distal end of the merus with a spine below, and at tha,t of the 

 wrist with one on the inside. The third and fourth pairs of legs 

 are subequal, reach the last third of the wrist of the second pair, 

 and are armed Avith several slender spines on the underside of the 

 propodite. The fifth pair reach halfway up the propodite of the 

 fourth, and have their own propodite armed with a strong spine at 

 the distal end on the underside and with two more slender ones 

 proximally of this. The carpus in each leg of the last three pairs 

 projects dorsally at the outer end as a blunt spine. 



The endopodite and esopodite of the uropod are subequal 

 and somewhat longer than the telson, which bears six spines at 

 the hind end. Of these spines the outermost are the shortest, and 

 the intermediate the longest. 



The length of the single specimen is 20 mm. from tlie tip of the 

 rostrum to the end of the telson. 



This species is closely allied to P. grandis (Stimpsou), but is 

 separated by the shortness of the fourth pair of legs, and of the 

 second as far as the end of the merus, and by its smaller size; and 

 is therefore perhaps better regarded as distinct, li P. petitlliouarsi 

 Miers (non Audouin) be rightly regarded as synonymous with P. 

 grandis Stimpson, we may add as further differences the presence 

 of six, instead of five, teeth on the dorsal border of the rostrum 

 (excludiug that on the carapace behind the rostrum in each case), 

 and of four, instead of three, teeth on the inferior border. The 

 rostrum, too, of Miers's species is " nearly straight," while that of 

 P. vitiensis has a marked upward trend at the free end. 



One female, with eggs, from Viti Levu, Fiji.
