The 10 arms are 100 mm. long, relatively more slender than the arms of related 

 species. 



Notes. One of the three specimens from off Cape Padaran, southern Annam, 

 has the arms about 90 mm. long, and the longest cirri about 70 mm. long with 83-85 

 segments. 



Of the five specimens from Albatross station 5482 one has 10 arms 90 mm. long 

 and the cirri 55-60 mm. long with 77-82 segments. Another has 10 arms 100 mm. 

 long and the cirri 75-80 mm. long with 82-107 segments. A third is similar. The 

 fourth specimen has 11 arms 100 mm. long, one IIBr 2 series being present, and the 

 cirri 60-70 mm. long with 85-94 segments. The fifth specimen is abnormal. 



Of the five specimens from Willebrord Snellius Station 60* one has 12 arms 100 

 mm. long, two IIBr 2 series being present, and the cirri 70 mm. long. The four others 

 all have 10 arms. In one the arms are 110 mm. long, and the longest cirri are 73 mm. 

 long. In another the arms are 100 mm. long, and the longest cirri are 60 mm. long; 

 in this specimen the first twelve brachials have the proximal edge more or less thick- 

 ened, giving the arm bases a somewhat rough appearance and a slightly, but very 

 distinctly, serrate profile with the teeth directed downward and outward. This 

 feature also occurs in the type specimen from Albatross station 5483. In one specimen 

 the sides of the arms are heavily mottled with brownish, the mottlings forming a 

 frequently interrupted broad lateral line which here and there becomes a row of 

 blotches or spots. The other specimens all show the lateral mottled line on the arms 

 more of less distinctly, but only one other shows the proximal median line. The 

 dark lateral line is also traceable in the type specimen.
