Station XIII. One specimen, a male, 4*5 mm. long. 



This species was established by Bruzelius in 1859. In 1868 Norman 

 described a specimen from the Shetland Isles under the name of 

 Cyrtophium armatum. He noted its resemblance to Bruzelius's species, 

 but considered it sufficiently distinguished from it by the following 

 ■characters : " much more strongly tuberculated ; and the gnathopods 

 of different structure, the first smaller, the second larger, the hand 

 broader and the basos spined." Sars in 1894, although he described 

 the two species as distinct because of the peculiar armature of the 

 body in armatus, was inclined to consider this latter form as merely a 

 deep-sea variety of tuherculatus, giving the range of distribution as 

 20-50 fathoms for tuherculatus and as 50-300 fathoms for armatus. 



The specimen taken by the Hmelcy was a large male, 4-5 mm. in 

 length, with the spinose armature even more accentuated than in the 

 figure given by Sars for armatus. Through the kindness of Canon
