process carrying three or four spines. The second maxillae in our specimens fully 

 agree with Smith's account, except that the fringing setse of the proximal lobe are 

 much longer relatively than those which he figures. The sharply pointed hind 

 portion of the scaphognath has, as he observes, on its inner margin setse of 

 remarkable length.

The species thus named was taken by the Challenger in lat. 60° 52' S. The 

 Scotia obtained a number of specimens in lat. 71° 22' S., which agree fairly well 

 with Bate's account of the rostrum, except that the lower margin for almost the 

 whole length is unmistakably fringed with setules. A single specimen from lat. 39° 

 43' S. has the rostrum devoid of setules. But the more or less damaged condition 

 of all the specimens makes it difficult to be sure that any two belong to the same 

 species or same variety, while, as above observed, the rostrum itself is subject to 

 variation. In none of the specimens examined could I find the fifth perseopod 

 complete. According to Bate, the scale or scaphocerite of the second antennae is 

 nearly as long as the rostrum. His figure represents it as much longer. In our 

 specimens it is decidedly shorter. The third maxillipeds do not reach the end of 

 the scale, and are outstripped by the fifth joint of the first perseopods, which almost 

 reaches that end. The second perseopods extend much beyond the rostrum. The 

 telson reaches the end of the uropods. It carries numerous pairs of little dorso- 

 lateral spines, and the narrow apex, besides some setules, has two contiguous spines 

 flanked by a much larger subapical pair. The specimens agree in size with Bate's 

 specimens, as some of them were about 130 mm. long, allowance being made for 

 broken off apex of rostrum or telson.
