produced to lose the effect of a rhomboidal termination ; the 

 sharply carinate finger fits closely and exactly to the oblique 

 finely tuberculate distal margin of the sixth joint. The third 

 legs are slightly longer than the second, the finger about as 

 long as the fifth and sixth joints combined, longitudinally 

 grooved on both sides, fringed with short fine hairs. The 

 fourth legs are surrounded with long plumose hairs, the 

 fourth joint little longer than the fifth or sixth, which are 

 both broad, the inner margin of the sixth joint coated with 

 subcircular scales, the apex projecting but little in opposition 

 to the rather long slender curved finger, which has a close-set 

 row of teeth following its curve and setae on both margins. 

 The fifth legs likewise have long fringes of serrate setae, the 

 sixth joint squamose distally behind the finger hinge, the 

 very small thick finger covered with long setae, closing down 

 upon the short almost transverse palmar margin. Of 

 P. piloswiamts, Smith, the French authors say that the fourth 

 legs are provided with an almost perfect chela (pince), and 

 that in the fifth legs the chela is narrower but longer, the 

 palmar portion being much more elongate than the digital 

 portion, but this latter statement may only mean that the 

 sixth joint is much longer than the seventh. 



The sixth segment of the pleon is almost completely 

 calcified dorsally. The uropods on the left are the larger. 

 The infolded telson is obliquely oval, with numerous little 

 spine teeth at and near the apical margin. 



Specimens in formalin retain for some time red markings, 

 almost all longitudinal, on body and limbs and on the eye- 

 stalks, the eggs a deep-red when first the mother is withdrawn 

 from a shell. The "Gazelle" specimens were in shells of 

 Buccinum forcatum, Gm., completely covered with colonies 

 of Epizoanthus cancrisocius v. Martens. Henderson reports 

 the species from the neighbourhood of Nightingale Island, 

 Marion Island, the coast of Patagonia, as well as from the 

 Agulhas Bank. The specimens here described were taken 

 34° 43' 15" S., 18-31' E. 



The greatest depth recorded for this species is 245 fathoms, 

 off Port Churruca, Patagonia (Challenger).
