specimens should be refevred to section B of Kiikenthal's Umbel- 

 latpe, and the presence of unequally long branches resulting in no 

 very uniform outline points to the spinulosa group. 



2. Branching. There is a distinct 



foliaceous collar. Text-fig. 30. 



3. Colouring. Cortex very hyaline 

 and bearing loosely disposed white 

 spicules. 



4. Polyp stalks. Slightly over 1 mm. 

 long. 



5. Polyps. Few are in good con- 



dition, owing to the colonies having 

 been much compressed in most cases ; 

 small groups of 3 or 4. 



6. Polyp sjyictdes. The anthocodial 

 points consist of 4-5 paii-s en chevron, 

 with almost no projection of the upper- 

 most pair and almost no crown. j)_ jnjaUna Xiik. 



The supporting bundle is fairly well 

 developed, and the strongest spicule may project for half a 

 millimetre. 



7. Other spicules. The sterile stalk shows numerous stellate 

 and multiradiate spicules.
