REPORT ON THE AMPHIPODA. 1387 



with the hind margin closely pectinate ; the finger slender, curved, about half the length 

 of the fifth joint, the bulb at the base squared, the inner margin faintly pectinate for a 

 short distance below this. 



Second Perxopods closely resembling the first, the fifth joint rather shorter. 



Third PersBopods. — The first joint scarcely longer than that of the preceding pair, 

 but broader, oval, narrowest above, the margins smooth, except for two minute spinules 

 on the upper part of the front, and a setule at its apex ; the four following joints longer 

 than in the preceding pair, the second rather broader, the third, fourth, and fifth, rather 

 narrower ; the fourth and fifth pectinate along the front margin and having a small 

 inward-curving spine at the apex ; the finger about a third of the length of the fifth 

 joint, its shape and armature as in the preceding pair. 



Fourth Perseopods differing little from the third, except that all the joints are a little 

 longer and, except the first, a little broader ; the first is rather narrower and has three 

 little spines disposed along the front margin. 



Fifth Perseopods slightly shorter than the third ; the first joint narrowed above, with 

 two small spines on the lower half of the front margin ; the four following joints rather 

 stouter than in the third perseopods, the fourth and fifth rather shorter. 



Pleopods not differing very materially from those described for Hyperia sibaginis. 



Uropods. — Peduncles of the first pair the longest, reaching back to a point midway 

 between the ends of the peduncles of the second and third pairs, longer than the rami, 

 the distal margin pectinate ; the outer ramus shorter than the inner, the outer margin of 

 the outer and the inner margin of the inner not toothed, the other two edges having the 

 ciliated emargination as described for Hyperia sibaginis, the remainder of the border being 

 pectinate with little teeth almost to the acute tip ; second pair like the first, but with the 

 peduncle considerably, and the rami a little, shorter ; third pair with the peduncles shorter 

 than those of the first, and longer than those of the second pair, the rami similar to 

 those of the other pairs but shorter. 



Telson scarcely if at all longer than broad, forming an inverted arch, the apex nearly 

 acute ; the length less than one-half, more than a third, of that of the peduncles of the 

 third uropods. 



Length, without the antenna?, a fifth of an inch. 



Locality. — Station 141, December 17, 1873; off the Cape of Good Hope; lat. 

 34° 41' S., long. 18° 36' K; surface; surface temperature, 66°'5. Several specimens, 

 that described and figured being a male. 



Remark. — The specific name refers to the capture of the species in the neighbourhood 

 of the Cape of Good Hope.
