slight dorsal tubercle. The 10 arms are 95 mm. long. The proximal brachials are 

 somewhat tubercular. Dorsal spines are developed from the fiftieth or sixtieth 

 brachials onward. The distal intersyzygial hiterval is 6-11 muscular articulations. 

 Pi is 6.5 mm. long with 12 segments. P2 is 7.5 mm. long with 12 segments. P3 is 7 

 nmi. long with 11 segments. The distal pinnules are 13.5 mm. long with 22 segments. 



Another specimen from station 59 has the centrodorsal 3 mm. high. The cirri 

 are XXI, 55+, 35+ mm. long. The radials are four times as broad as long and have 

 a slight dorsal tubercle. There are 13 arms, all of which are broken. In one case 

 the first syzygy is between brachials 1+2. Pj is 5 mm. long with 10 segments (or 

 8 if on an arm foUowiag a IIBr axillary). P2 is 6 mm. long with 9-10 segments. 

 P3 is 5.5 mm. long with 8 segments. 



From station 59 another specimen has the centrodorsal sharply conical, 2.8 mm. 

 high. The cirri are XX, 60-70, 30-55 mm. long. The proxhnal row of prominences 

 on the cirri is indistinctly separated from the distal. The radials are three times as 

 broad as long with a dorsal tubercle which is indistinctly delimited distally. The 10 

 arms are 85 mm. long. The brachials develop dorsal spines from the fiftieth onward. 

 The distal mtersyzygial interval is 4-5 muscular articulations. Pj is 6.5 mm. long 

 with 11 segments. P2 is 9 mm. long with 13 segments. P3 is 8 mm. long with 11 

 segments. P4 is 6 mm. long with 10 segments. Pj is 7.5 mm. long with 14 seg- 

 ments. The distal pinnules are 12.5 mm. long with 21 segments of which the longest 

 are at least three times as long as broad. The disk is 6 nm;i. in diameter. 



In another specimen from station 59 the cirri are XVIII, 50-65, 30-50 mm. long. 

 The radials are four times as broad as long with a dorsal crest. The 1 1 arms are 70 

 mm. long. Dorsal spines are developed from about the fortieth brachial. The distal 

 intersyzygial interval is 6-9 muscular articulations. Pi is 6 mm. long with 11 seg- 

 ments. P2 is 6.5 mm. long with 11 segments. P3 is 6.5 mm. long with 9-10 segments. 

 P4 is 6 mm. long with 11 segments. The distal pinnules are 11 mm. long with 18 

 segments which are from two and one-half to thi-ee and one-half times as long as 

 broad. 



Another specmien from station 59 has the centrodorsal bluntly conical, 3 mm. 

 high. There are XXII cirri. The radials are five times as broad as long with a 

 dorsal tubercle. There are 11 arms 95 mm. long. From the sixtieth onward the 

 brachials develop a dorsal spine that rises to a height equal to one-third the width 

 of the brachial. The distal intersyzygial interval is 4-7 muscular articulations. Pi 

 is 7 mm. long with 12 segments. P2 is 9 mm. long with 13 segments. P3 is 7 mm. 

 long with 11 segments. P4 is 8.5 mm. long with 13 segments. The distal pinmdes 

 are 10+ mm. long composed of segments from twice to two and one-half times as 

 long as broad. 



In a spechnen from station 59 the cirri are XX, 61-82, 40-65 mm. long. The 

 radials are four times as broad as long with a dorsal tubercle. The 10 arms are 85 

 mm. long. The brachials develop dorsal tubercles from the fiftieth onward. The distal 

 intersyzygial interval is 4-6 muscular articulations. P2 is 7 mm. long with 12 seg- 

 ments. P3 is 7 mm. long with 10+ segments. The distal pinnules are 11.5-13.5 

 mm. long with 17-20 segments which are from two and one-half to three times as long 

 as broad. 



A specimen from station 59 has the centrodorsal bluntly dome-shaped, 4.5 mm.
