 with 107 — 116 Br-s. The arms proximally wall-sided thus, that the 

 lateral borders of I Br 1 ai-e contiguous, and the left side of 1 Br 



2 + the first segment of the pinnule correspond to the right side of 

 1 Br 2 and 3. Syzygies after a 111 Brax 3 + 4, 37 + 38, 52 + 53, 

 70+71, 107 or 3 + 4, 26 + 27, 50 + 51, 74 + 75, 87 + 88, 113+114.

Pj 24 — 32; 30 — 35 mm. The 10 most proximal segments sharply 

 quadrangular, strongly compressed laterally after the 2'' segment, with 

 ambulacral furrow, (to the right on I Br 2 in 5 eases), Pg 24 — 30; 

 Pj — Pjii the shortest ones, then longer p-s again. The most distal seg- 

 ments on Pj — P^ with collars with small spines. From P^ smooth 

 segments. The p-s from the middle parts of the arms 12 — 15 mm. 

 The last 20 pairs of p-s rudimentaiy with 2 — 4 segments. 



Chalice in transverse section about 20 mm. Colour (in spirits) 

 whitish, the arms light brown. Syzygial pairs white. — Disk with 

 coarse granules. — The specimen handed over to the museum at 

 Gothenburg. 



Sp. 2 (St. 31) 23 Internodes, 350 mm. Interarticular pores to 

 the 1 1"' internode. 4 nodal joints without cirri. Full number of in- 

 ternodals in the 6*'' internode. Internodal joints 11: 10 cases, 12:6 

 eases, 13: 2 eases (11 distally, 12 proximally); 15 — 18 mm. Diameter 

 of the stem 6,o — 6,2 mm. 



Cirri 53 (IX"^ node), 55 mm., 49 (X) 53 mm., 46 (XIX) 50 mm., 

 49 (XXIl) 50 mm. Extending over 2'''2 — 3 internodes. Cirrals 1,5—1,8 

 mm. in cross section. The last 20 — 30 segments with a double dorsal 

 spine as in Sp. 1. The facet for the cirrus extending over ^/4 of the 

 nodal and over '/4 of the supranodal joint. Interradial tubercles on
