810 THE VOYAGE OF H.M.S. CHALLENGER. 



Uropods. — Peduncles of the first pair longer than the rami, which are subequal, the 

 outer rather the longer, each with a distal group of spines ; peduncles of the second pair 

 shorter than the longer, longer than the shorter, ramus ; both rami with apical groups of 

 spines, the longer with pectinate margin and spines at two points upon it ; peduncles of 

 the third pair much shorter than the lanceolate rami, of which the outer is a little the 

 shorter. 



Telson very long and narrow, reaching far beyond the peduncles of the third uropods, 

 sharply tapering, cleft nearly to the base, and distally scarcely dehiscent, the apex of 

 each half tipped with a spine. 



The Length of the outstretched specimen as figured was rather over four-twentieths 

 of an inch, of the coiled specimen as figured three-twentieths. 



Locality.— Betsy Cove, Kerguelen, January 10, 1874. Four specimens. 



Remarks. — The details have been figured from a female specimen. The specific 

 name, derived from iravpoi, few, and SciktuXo?, a finger, refers to the scarcity of fingers in 

 this creature, for they seem to be wanting in the maxillipeds, the second gnathopods, 

 the first, second, and fifth perseopods, to be rudimentary in the first gnathopods, 

 and very short in the third and fourth perseopods.

From Scudder's Nomenclator Zoologicus it appears that the name Phoxiis, was pre- 

 occupied among Coleoptera by Billberg in 1820 ; I have therefore substituted the form
