In the specimen from Princesse-Alice station 578, the second syzygy is between 

 brachials 9 + 10 on 3 arms and between brachials 11 + 12 on one; the fifth arm is broken 

 off near the base. 



The specimen from Princesse-Alice station 1118 shows some anomalies which, as 

 suggested by Prof. Koehler, are doubtless the result of the regeneration of the left 

 anterior, right posterior and left posterior arms. On the normal arms (anterior and 

 right anterior) the first syzygy is between brachials 4 + 5, the second is between bra- 

 chials 9 + 10, and the third is at the distal end of brachial 14, the arms being broken 

 off here. On the left anterior arm the first syzygy is between brachials 4 + 5 and the 

 second between brachials 6 + 7; the next is between brachials 8+9; the arm has been 

 broken off between brachials 9 and 10, and has regenerated. In this regenerated por- 

 tion syzygies occur between brachials 14 + 15 and 18 + 19, and the arm is lost at the 

 distal syzygial face of brachial 24. On the left posterior arm regeneration has taken 

 place at the syzygial distal face of brachial 4 ; the second syzygy is between brachials 

 8+9 and the arm is lost at the distal syzygial face of brachial 12. 



[NOTES BY A.M.C.] Gislen (1928) noted that the specimen in the British Museum 

 from Helga station S.R. 489, has the centrodorsal low conical. The radials are hidden 

 and the disk extends to brachial 5. I agree that the centrodorsal is low conical. It 

 is 2.7 mm. in diameter and 1.5 mm. high. There are XXXIV cirrus sockets in three 

 irregular rows around the sides and the dorsal pole is covered with papillae. No 

 complete cirrus remains attached but a peripheral one with 10 segments left 

 measures 19 mm. The first two segments are shorter than wide; the third is about 

 two and a half times as long as its median width; the fourth is nearly four times as 

 long as wide and the longest segments are five times as long as wide. The apical cirri 

 are narrower and with relatively longer segments. A detached outer portion of a 

 nonperipheral cirrus measuring 9 mm. with 10 segments, has the tapering penultimate 

 segment three times as long as wide. The terminal claw tapers abruptly near its base 

 and its slightly curved outer half is attenuate and sharp. 



The first syzygy at brachials 4 + 5 measures 1.8 mm. in width and the brachials 

 to the second syzygy at 9+10 total 8.5 mm. in length. The first brachial is very short. 



The first few pinnules, which bear gonads, have the first two segments short but the 

 third is half again as long as broad and the following ones become a little longer. Their 

 joints are slightly expanded and spinous.
