75"' segment, rather Ioav. P4 12; 6,5 mm. Tlie L of distal pinnulars 

 2—21/2 br. 



Sp. 23 (St. 5t)) R— s h- 1/3 br with a slight tubercle. Dorsal 

 Br-spine from the 50* segment. ThQ L of distal pinnulars 2 br, 



Sp. 24 (St. 59) H of Cd 3 mm., eylinch'ical, dorsaliy rounded 

 with a small cavity. R--s h = i/e br with a dorsal crista; a slight 

 earination on I Br 1 and 2. Dorsal Br-spine rather weak, from about 

 the 50"' segment. The L of distal pinnulars 2 br. — Parasitic Shjlinas. 



Hp. 25 (St. 59) R— s h = i/4 br with a dorsal tubercle. I Br 1 

 smooth. Arms broken. 



Sp. 26 (St. 59) Cd a rather low (h = 2 mm.), pointed cone. 

 The short dorsal cirri with the 7"'— 14"' segments slender, L = 2 br. — 

 R — s h = 1/3 br with a dorsal crista. Dorsal Br-spine from the 50"' 

 segment. The L of the distal pinnulars 2 — 2 1/3 br. Disk 7 mm. 



Sj). 27 (St. 59) H of Cd 3,r, mm. R— s h = 1,3 br with a dorsal 

 crista. Dorsal Br-spine from the 50"' segment. The L of the distal 

 pinnulars 2 — 2 1/2 br. 



.S^). 28 (St 46) Cd: h: 3, br: 3 mm. Most cirri broken or very 

 small. From the 7"' cirral a dorsal crista which is gradually trans- 

 formed into a dorsal spine. R — s h = 1/2 — 1/3 br with a small dorsal 

 tubercle. B — s IR visible. Dorsal Br-spine from about the 55**' seg- 

 ment, strongly curved, slowly increasing. The L of the distal pinnu- 

 lars 21/2 — 3 br. 



Sp. 29 (St. 46) A young individual. Cd smaller, h = 1 mm. 

 Cirri slender, as in the dorsal whorl in older specimens. R— s: h^=i/j 

 or "/3 br with a dorsal longitudinal crista. The arm-bases laterally 

 flattened out to Br 4. Dorsal Br-spine from the 50"' segment; because 

 of the shortness of the arms only a small part of the arms spiny. The 

 L of the distal pinnulars 2i/2 br. 



Sp. 30 (St. 53) R— s h = 1/5 br with a dorsal tubercle. Dorsal 

 Br-claw from the 45"' segment. The L of distal pinnulars on the 

 distal pinnules 2 br. 



Sj). 31 (St. 53) Cd with an arched and rounded dorsal pole. The 

 proximal and distal series of prominences on the cirri not distinctly 

 separated. R — s h = i/4 br with a dorsal spine or crista. II Br— s as 

 always : 2. A pair of new regenerated arms of somewhat unequal size.
