In a specimen from Bock's station 47 the centrodorsal is 2 mm. in diameter, 

 the bare dorsal pole being 1.5 mm. across. The cirri are XX, 10-11, 4 mm. long; 

 4 of the cirri are very small. The IBri are eight times as broad as long. The IBrj 

 (axillaries) are five times as broad as long. The 10 arms are 30 mm. long. Syzygies 

 occur usually between brachials 1+2 and 3+4. Pj is 4 mm. long with 24 segments, 

 of which 9 bear teeth. P2 is 3.5 mm. long with 20 segments, of which 9 bear teeth. 

 P3 is 3 mm. long with 11 segments. The distal pinnules are 3.5 mm. long with 14-15 

 segments. The bases of the pinnules bear swollen gonads. The disk is 3 mm. in 

 diameter. The color is brown. 



In another specimen from Bock's station 47 the cirri are XX, 8-9, from 2 mm. 

 to 3 mm. long. The IBr, are as in the preceding. The IBr2 (axillaries) are three 

 times as broad as long. The 10 arms are 27 mm. in length. Pi and P2 bear combs. 

 P3 is 3.5 mm. long with 9 segments. The distal pinnules have 13 segments. 



In another example from Bock's station 47 the cirri are XIX, 9-10, from 3 mm. 

 to 4 mm. in length. The IBri are eight times as broad as long. The IBrs (axillaries) 

 are thi-ee times as broad as long. The 10 arms are 25 mm. long. The first 2 brachials 

 are each four times as broad as long. Pi is 4 mm. long with about 25 segments, of 

 which 8 bear teeth. P2 is 3.5 mm. long with 20 segments, of which 7 bear teeth. P3 

 is 3 mm. long with 12 segments. The distal pinnules have 12 segments. The gonads 

 are only slightly swollen. 



Another specimen from Bock's station 47 has the centrodorsal 1.8 mm. in diam- 

 eter. The cirri are XIII, 9-10, from 2 mm. to 3 mm. long. The IBri are three times 

 as broad as long. The IBr2 (axillaries) are twice as broad as long. The comb on 

 Pi consists of 8 teeth. P2 bears a comb. The gonads are only slightly swollen. 



In another example from Bock's station 47 the centrodorsal is 1.8 mm. in diam- 

 eter. The cirri are XIV, 9-10, from 2.5 mm. to 3 mm. long. The IBrj are three 

 times as broad as long. The IBr2 (a.xillaries) are twice as broad as long. The comb 

 on Pi consists of 8 teeth. P2 bears a comb. P3 is 2 mm. long with 10 segments. The 

 gonads are only slightly swollen. 



A specimen from Bock's station 55 has the cirri XIX, 10, 3 mm. long. The 

 10 arms are 25 mm. long. Pi and Po have combs with 8 teeth. The distal pinnules 

 have 12 segments. The gonads are well developed. 



Another specimen from Bock's station 55 has the cirri XIX, 9-10, from 3 mm. 

 to 4 mm. long. The IBri are almost completely concealed. The IBr2 (axillaries) 

 are three times as broad as long. The 10 arms are 30 mm. long. Pi and P2 have 

 combs. The gonads are well developed. 



Another specimen from Bock's station 55 has the cirri XV, 8-9, 3 mm. long. 

 The IBri are almost completely concealed. The IBr2 (axillaries) are three times as 

 broad as long. Pi and P2 have combs. The gonads are well developed. 



Another example from Bock's station 55 has 10 arms 22 mm. long. Pi and P2 

 have combs. The distal pinnules have 10 segments. This specimen is attached to 

 a worm tube. 



Another individual from Bock's station 55 has 10 arms 14 mm. long. Pi and P2 

 bear combs. The gonads are somewhat swollen.
