Explanation of the plate. 



Vig. 1. Gomatula peetinata (specimen 12, see the description). X. B. the greatly enlarged joints and 

 segments on the proximal part of the posterior arms and their short. clumsy pinnules. Enlarged twice nat. size. 



Vig. 2. Comatula peetinata var. purpurea (specimen 13 in the description). The cirri of typical 

 purpurea distribution. The anterior arms Ionger, more slender, the posterior oncs shorter and coarser. Nat. size. 



Vig. 3. Comaster typica (specimen 2. ef. the text). Cd with few, feebly developed, short cirri fixed 

 in grooves, which are lowered in Centrodorsale. 2 /i. 



Vig. 4. Comaster multifida juv. (the broken arm is indicated as N:r 17 in tlie text). The syzygies 

 on arm 4 are plainly visible. The pinnules very spiny. 8 /i. 



Fig". 5. Zygomctra microdiscus var. elegans. Nat. size 



Vig. 6. Amphimetra milberti (Station 9). The distal part of the arms is of a paler colour. The 

 transition between the proximal dark and the distal liglit segments often very sharp, appearing in a hypozygalc 

 or just in the segment coming before this ossicle. Probably fully regenerated but not yet »reroloured» arms. 

 A secondary regenerate is indistinctly visible in the most distal part of an arm to the left. — Nat. size.

 varying length and mutual relation in these pinnules a) from specimen 1, b) trom sp. 15, c) sp. 2, d) sp. 9,
