REPORT ON THE AMPHIPODA. 819 



Uropods. — Peduncles of the first pair subequal to tlie rami ; the longer of the two 

 rami with two or three spines on the upper margin, the shorter with none ; the second 

 pair smaller than the first, the peduncles with one rather prominent apical spine ; the 

 rami without spines, equal in length to one another and to the peduncle ; peduncles 

 of the third pair shorter than the rami, carrying some apical spines ; the rami lanceolate, 

 the outer longer than the inner by almost the length of its long slender nail, which has a 

 couple of cilia at its tip, and spines on either side of the base ; there is also a small spine 

 on the outer margin of the longer ramus, the shorter has a cilium at its tip. 



Telson extending a little beyond the peduncles of the third uropods, cleft beyond the 

 middle, the apices somewhat divergent, each armed with a long spine, and a cilium outside 

 of the spine ; the outer margins appear to be evenly convex and unarmed ; the length 

 not greatly exceeding the breadth. 



The Length of the female specimen, in the position figured, was rather less than one- 

 fifth of an inch. The details were figured from a male specimen, with the exception of 

 the lower antennae of the female. 



Locality. — Off Cumberland Bay, Kerguelen, at a depth of 120 fathoms. Several 

 specimens. 



Remarks. — The specific name is derived from the place of capture. 



A dark-coloured specimen, less than a tentli of an inch in length, from Marion Island, 

 appears to be of this species, though presenting some differences. 



The present species differs from Phoxocephalus bassi in many particulars, but the 

 gnathopods alone suffice to distinguish the one species from the other.

For Boeck's definition of the genus see Note on Boeck, 1870 (p. 400). Gerstaecker 

 in 1886 makes Harpina, Boeck, a synonym of Fhoxus, Kroyer, but in the definition 

 he includes as a character, " die drei hinteren Beinpaare mit lamellos erweitertem 

 Schenkelglied," which is unsuitable to Harpinia, since there the first joint of the third 

 pergeopods is not expanded. Fhoxus plumosus, Kr0yer, is the type species of Boeck's 

 Harpinia, so that the writers prior to 1870 who have mentioned Phoxns lilnmosus, as 

 Spence Bate, Goes, &c., might be included in the above synonymy.
