SPECIES OF VKV,ELLVLA~co>iihmed. 



Autozooids. 



Form a bunch at end 

 of stalk without any 

 trace of bilateral 

 arrangement. 



Siphonozooids. 



Tentacles longer than 

 the body. Autozooids 

 6-11 mm. long, ten- 

 tacles about 20 mm. 



Numerous on the upper 

 enlargement of the stalk 

 at the base of the auto- 

 zooids, and also on the 

 long swelling of the 

 stalk, and in its neigh- 

 bourhood. 



Form tongue-shaped areas 

 between the polyps. 

 Below the cluster they 

 are disposed all round, 

 but downwards they 

 pass into a single row on 

 each side. 



Spicules. 



Absent. 



Tentacles about same 

 length as, or shorter 

 than, the body. 



Between the autozooids in 

 tongue-shaped areas. 

 Each has a ventral ten- 

 tacle. Also over the 

 whole stalk. 



Tentacles are about Occupy the space between 

 15 mm. long. the bases of the auto- 



zooids. 



Few and large, arranged Small, not prominent ; 

 in a whorl or bi- occur all over the rachis. 

 laterally. 



Five in number, one 

 terminal ; of medium 

 length, with long tent- 

 acles ; rigid, covered 

 by spicules visible to 

 the naked eve. 



One terminal and two 

 pairs of lateral ; 5-6 

 mm. long, 2-5 mm. in 

 diam., tentacles 6 mm. 

 long. 



Small ; occur in meshes 

 in the spicular covering 

 all over the rachis except 

 on the prorachidial ridge. 



On metarachidial extend- 

 ing to the i>rorachidial 

 surfaces. 



Absent except in the 

 lower part of the stalk, 

 where they are numer- 

 ous ; 0-016 mm. x 

 0-0064 mm. 



Very small spicules are 

 found, but only in the 

 lower end of the 

 peduncle. 



Absent.

 rods covered by longi- 

 tudinal ribs ; (2) long 

 rods with minute tuber- 

 cles ; (h) ccenenchyma — 

 rods and quadriradiate 

 forms. 



(a) Rachi.s — rough rods or 

 bars, blunt at the ends 

 and ridged ; (h) stem — 

 smaller and proportion- 

 ally wider rods. 



(a) Stalk — short, thick 

 ellipses, with numerous 

 ribs ; (/)) autozooids — a 

 few longer and propor- 

 tionall}- thinner, rough 

 ellipses.
