REPORT ON THE AMPII1PODA. 1223 



half, the hind margin nearly straight, carrying a few cilia ; the rest of the limb very 

 similar to that of the third perseopods, the finger rather longer. 



Fifth Penropods. — The side-plates a little broader but not quite so deep as in the 

 preceding segment, the hinder margin convex, much longer than the front, the lower 

 margin very convex. The first joint greatly expanded, a little longer than broad, the 

 front margin nearly straight, with two or three spinules on the lower part, the hind and 

 lower margins smooth, curved ; the second joint very short, with two or three spinules 

 on the front margin, behind overlapped by the first joint ; the third joint much smaller 

 than in any of the other perseopods, with spinules at three points of the front margin, 

 and one on the hind margin, of which the sharp decurrent apex quite overlaps the small 

 fourth joint ; the fifth joint shorter than in the preceding pair, but considerably longer 

 than the fourth joint ; the finger more than half the length of the fifth joint. 



Pleopods. — The peduncles rather widely sejiarated at the bases, with two little oval 

 processes projecting between them. The coupling spines small, with slender shafts, 

 having three or four retroverted teeth on each margin ; a single cleft spine on the inner 

 ramus ; the inner ramus seemingly with five, and the outer with six, joints. 



Uropods. — The peduncles of the first pair longer than the rami ; the rami acute, the 

 lower and outer longer than the upper and inner, the lower having two small spines, the 

 upper having one on the proximal half; the peduncles of the second pair about equal in 

 length to the rami, which resemble in shape those of the first pair, but are unarmed, 

 reaching very little beyond the peduncles of the first pair, the lower and outer rather 

 longer than the other ; of the third pair the peduncles were not clearly discovered and 

 must in any case be very short ; the single ramus of each uropod curved in towards the 

 other, being broader distally than at the base, the two lying apparently under a shallow 

 transparent telson. 



Telson not clearly distinguished, seemingly very small, wider than its length, forming 

 a small arc of a circle. 



Length from the front of the head to the back of the third pleon-segment, in the 

 position figured, about one-seventh of an inch. 



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

 127 fathoms; bottom, volcanic mud. Two specimens. 



Remark. — The specific name explains itself. 



Family Pardaliscid^e, Sars (see p. 990). 

 Synopioides macronyx (see p. 1000). 



A second specimen of this species, which, like that already described, had been 

 mounted in glycerine during the voyage, was labelled " Townet at trawl, Nov. 1875, 

 2025 fms., South Pacific.''' It may be presumed that this belongs to Station 293,
