REPORT ON THE AMPHIPODA. 1091 



pair. Side-plates small. All the joints of the limb longer than in the fourth peraopods, 

 but the third, fourth, and fifth joints especially so ; the third joint is longer than the 

 fourth but shorter than the fifth ; the fourth joint is elongate, with spines at four points 

 of the hind margin or near it ; the fifth joint has spines not regularly spaced at 

 seven points of the front margin ; the finger is scarcely one-third the length of the 

 fifth joint. 



Pleopods. — Coupling spines slender, bent, with an apical pair of retroverted teeth and 

 a similar pair a little below the apex ; the cleft spines are three in number on the first 

 pair and two only on the third; there are some small surface spines on the first joint of 

 the inner ramus ; the joints of the inner ramus ten in number, of the outer and shorter 

 only nine. 



Uropods. — The peduncles of the first pair a little longer than the rami, with few 

 marginal spines, a large spine at the lower apex ; the rami equal in length, or nearly so, 

 the inner with five spines along one upper margin, two or three near the top of the lower, 

 and a large apical group, the outer ramus with two spines low down on one margin and 

 an apical group ; the peduncles of the second pair not so long as the inner ramus, with 

 two spines at the inner apex and a large one at the outer ; the longer ramus has four 

 spines on one of the upper margins, two on the other, two near the top of the lower 

 margin, and a large apical group of five ; the shorter ramus has three spines on the upper 

 margin and an apical group of five ; the peduncles of the third pair shorter than the short 

 rami ; the inner ramus rather the shorter, with two rather elongate spines below the 

 centre, and five at the blunt apex, one with a setiform termination ; the outer ramus 

 similarly armed, but with the terminal spines longer, three of them with setiform 

 ends. 



The. Telson very little longer than broad, reaching beyond the peduncles of the third 

 uropods, the centre of the distal border convex, the extremities acute, with a long seti- 

 form spine projecting from the surface above and within each ; there is also a marginal 

 cilium or two a little higher up. 



Length. — The specimen, in the position figured, measured, in a straight line from the 

 front of the head to the extremity of the uropods, one-fifth of an inch. 



Locality. — Station 149h, off Cumberland Bay, Kerguelen, January 29, 1874 ; depth, 

 127 fathoms; bottom, volcanic mud. One specimen. 



Remarks. — The specific name refers to the place of capture. A female specimen from 

 the same locality, which I regard as probably belonging to this species, has the wrist of 

 the first gnathopods nearly as long as the hand, the hand itself dilated at the palm, 

 which has no dental process, but is finely pectinate as in the second gnathopods, the 

 nail of the finger reaching beyond it and antagonising with a long palmar spine.
