 Br-spine from the 50''' segment. The L of distal pinmilars 2 br. 



Sp. 24 (St. 59) H of Cd 8 mm., eylindrieal, dorsally rounded 

 with a small cavity. R— s h-=V,6 br with a dorsal crista; a slight 

 earination on 1 Br 1 and 2. Dorsal Br-spine i-ather weak, from about 

 the 50"' segment. The L of distal piniiulai's 2 lii'. — Parasitic Shjlinas. 



Sp. 25 (St. 59) R-s h ' t br with a dorsal tubercle. I Br 1 

 smooth. Arms broken. 



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

 The short dorsal ciii'i with tlu' 7"' — 14"' segments slender, L = 2 br. —

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

 formed into a dorsal spine. R — s h = ^2 — '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-

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

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

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