P 2 is 4.7 mm. long with 8 segments. P 3 is 3 mm. long with 7 segments. P 4 has 6 

 and P 5 has 7 segments. The distal pinnules are 5.5 mm. long with 14 segments. 



A third specimen from Mortensen's station 7 has the cirri XXI, 44-61, 22-31 

 mm. long; the longest cirrus segments is one-third again as long as broad. The 15 

 arms are 70 mm. long. P t has 11 segments, P 2 has 8 segments, and P 3 has 6 segments. 

 The distal pinnules are about 5 mm. long with 10-12 segments. 



A specimen from Mortensen's station 9, according to Gislen, has the cirri about XX, 

 58, 28 mm. long. The 15 arms are all broken. The proximal crest is tolerably even 

 with notches only at the articulations. PI is 5.5 mm. long with 11 segments. The 

 disk is incised, 3.5^1.5 mm. in diameter. The anal cone is 1.5 mm. high. 



Two dried 10-armed young from Mortensen's station 9 have the arms about 30 

 mm long; one cirrus in the smaller specimen is 17 mm. long with 44 segments. 



Professor Gislen wrote that the appearance of the cirrus sockets is interesting as 

 it presents similarity with those of certain cretaceous comatulids in the families Noto- 

 crinidae and Conometridae, and the Essenensis and Paradoxus groups of Glenotremites. 



The specimens from Sagami Bay collected by Alan Owston are yellow with a broad 

 line on the division series and arms and a lateral line on the arms white; the cirri are 

 banded yellow and white, and the pinnules are blotched yellow and white. 



One of the specimens from Albatross station 3719 has 20 arms 80 mm. long and the 

 cirri 45 mm. long. 



Parasite. Professor Gislen noted that a specimen from Mortensen's station 7 

 was infested with a parasitic gastropod of the genus Eul"ma (see Part 2, page 649, 

 Melanella sp.).
