The three specimens from the Inland Sea are fine examples of the species with 

 14, 15, and 19 arms from 70 to 80 mm. long. 



The specimen from Albatross station 4948 is medium sized with 1 1 arms. 



Of the 6 specimens from Albatross station 4935 one has 10 arms 40 mm. long; 

 two have 18 arms; one is small with 20 arms; one has 20 arms 70 mm. long; and one 

 has 30 arms. 



The 31 specimens from Albatross station 4934 all have 20 arms, except one which 

 has 16 arms 50 mm. long. 



The specimen from Albatross station 4884 has 10 arms 40 mm. long. 



The specimen from Mortensen's station 14, according to Gisl6n, has the cirri 

 XXV, 22-26, from 7 to 10.5 mm. long. The longest cirrus segments are from half 

 again to twice as broad as long. From the sixth segment onward there is a transverse 

 dorsal ridge, transforming into a double dorsal spine which, about four or five seg- 

 ments before the opposing spine, is replaced by a smgle one. The dorsal spines are 

 relatively insignificant. The 17 arms are 60 mm. long. The intersyzygial interval 

 is 5-7 muscular articulations. P, is 5.5 mm. long with 14 segments. P2 is 7 mm. 

 long with 16 segments. P3 is 4.5 mm. long with 11 segments. The disk is naked 

 and much incised, 4 mm. in diameter. The color is mottled violet and white. 



The specimen from lat. 33°00' N., long. 129°24' E., m 55 meters, is small, with 

 10 arms. 



Of the 12 specimens from near Hirado Island in 73 meters 8 are small with 10 

 arms, one is medium sized with 10 arms, one is small with 11 arms, one is small with 



12 arms, and one is medium sized with 20 arms. 



The specimens from Albatross station 4902 have from 17 to 20 arms. 



The specimens from Albatross station 4903 have mostly 20 arms. 



The specimens from Albatross station 4895 are all large with 11, 16, and 18 arms 

 40 mm. long. 



The three specimens from Albatross station 4904 have 10, 12, and 20 arms. 



The specimen from Albatross station 4894 has 15 arms. The proximal third 

 of the arms is white and the distal two-thirds is purple. 



Of the 16 small specimens from lat. 33° 05' N., long. 128° 22' E., in 46 meters 

 one has 11 arms and the remainder have 10 arms. 



The specimen from lat. 32° 10' N., long. 128° 20' E., in 183 meters is a fine 

 example of the species with 19 arms 80 mm. long; the synarthrial tubercles are rather 

 more prominent than usual. 



The specimen from lat. 33° 08' N., long. 129° 20' E., in 66 meters, is small with 



13 arms. The individual is in process of adolescent autotomy, the three IIBr series 

 being only partly grown. 



The specimen from lat. 33° 09' N., long. 128° 18' E., in 183 meters, has the arms 

 40 mm. long. 



In one of the specimens from Mortensen's station 9, as described by Gisl^n, the 

 curi are XV, 17-20, from 6 to 8 mm. long. The 11 arms are all broken. The inter- 

 syzygial interval is from (2) 4 to 8 muscular articulations. 



In another specimen from Mortensen's station 9 the centrodorsal is 1.9 mm. in 

 diameter with the flattened dorsal pole 1.2 mm. in diameter. The cirri are XIII, 

 arranged in a single row, all broken. There were at least 13 arms 55 mm. long
