adjacent IIBr series is 1 mm. broad. Two postradial series are in process of multi- 

 plicative regeneration. P 4 and the preceding pinnules have a low and often indistinct 

 comb. The distal pinnules are 10 mm. long and have 24 segments. The diameter 

 of the disk is about 14 mm. 



In a young specimen from Bock's station 18 which Gisle"n with some doubt 

 assigned to this species the cirri are XII, 10-12, from 2.5 to 3 mm. long. The third- 

 fifth segments are the longest, half again as long as broad. 



The radials are three times as broad as long. The IBrj are twice as broad as 

 long and are laterally free. The IBr 2 (axillaries) are half again as broad as long, penta- 

 gonal, with the distal margins straight. 



The 10 arms are 7 mm. long. The first brachials are almost free interiorly. The 

 brachials distally are spiny and overlapping. 



PI has an indistinct comb. The tip of the pinnule is smooth. The comb consists 

 of 7 low and obtuse well separated teeth. The second-fourth or -fifth pinnules are 

 lacking. 



The disk is 2.3 mm. in diameter. The mouth and anus are subcentral. The anal 

 cone is 1 mm. high. The disk is rather "lean," and is weakly papillated. 



The specimen from Ito collected by Doctor Haberer in 1904 is typical, but much 

 broken. 



Of the 4 specimens from between Ito and Hatsushima one (4200) is a large exam- 

 ple with 40 arms, all of the IIBr and IIIBr series being present. The dorsal side of 

 the division series is more convex than usual, showing an approach to C. japonica. 

 Another (4202) is a magnificent specimen with 37 arms 160 mm. long. The division 

 series are exceptionally broad and massive. The cirri are 35 mm. long, stout, com- 

 posed of 28-31 segments. The remaining 2 are typical. One (4209) has 35 arms 

 150 mm. long, and the cirri 35 mm. long. 



Of the 3 specimens from Fukuura the 2 included in No. 4141 are typical examples 

 with 40 and 37 arms about 150 mm. long. The third (4122, part) is large, with 34 

 arms. The division series are broad and massive. The cirri are large and stout, 

 about 35 mm. long, and are composed of 33-35 segments. 



The specimen from Aburatsubo (294) is a magnificent example with 40 arms 200 

 mm. in length. It is quite typical of the species. 



Professor Doflein's specimen from Misaki (335) is small with 15 arms 45 mm. in 

 length. One IIBr 4 (3 + 4) series is developed on each ray. 



Of the specimens from Albatross station 3703, 1 has 39 arms about 140 mm. long, 

 and the cirri about 40 mm. long. Of the remainder 4 are 10-armed young. 



The specimen from Mortensen's station 16 has the cirri about XXX, 23-26, from 

 20 to 32 mm. long. The 26 arms are 105 mm. in length. The width of the IIBrj is 

 3.2 mm. The interspace between adjacent IIBr series on neighboring rays is 1 mm. 

 The distal angle of the IBr axillary is very inconspicuously extended. The elements 

 of the division series are rather strongly rounded dorsally. The pinnules as far as 

 P 6 have combs. P D is 21.5 mm. long and bears a comb consisting of 18 teeth. P 2 

 carries a comb of 12 teeth, the tip of the pinnule being smooth as usual. The comb 

 of P 5 has 4 teeth. The disk is 26 mm. in diameter, and is without granules. The 

 color is violet brown, the dorsal side of the arms with a narrow bright yellow longi- 

 tudinal band.
