Notes. In my memoir of 1896 I supplemented and corrected Ly- 

 man's description, and I find the characters typical for the species 

 in the Albatross specimens. The spines, which are four or five in 

 number on the first arm segments, may subsequently reach six. I 

 include here three photographs of the specimen from station 5647 

 (pi. 81, figs. 2, 6, 10). 



Lyman's type came from the vicinity of New Guinea (depth 1,957 

 meters [1,070 fathoms]). The Investigator found 0. aequalis in 

 the Laccadive and Andaman Islands, in 896 and 2,194 meters (490 

 and 1,200 fathoms), and the Siboga in the Sunda Archipelago (828 

 to 1,788 meters, or 455 to 980 fathoms).
