190 ALCYONARIA FROM THE INDIAN AND PACIFIC OCEANS. 



opposite sides of the lateral holes. The polyps are non-retractile and project 

 beyond conical calicos. 



In variety B, the lateral branches come off very regularly on alternate 

 sides of the main trunk and are tubular at their commencement, becoming 

 two parallel branches facing one another. Polyps non-retractile, but conical; 

 calicos not so much developed as in A. 



In variety C, the lateral branches are borne on opposite sides of the lateral 

 holes, and the latter are exactly opposite one another so that a front view of 

 the colony looks like the tail of a kite, and a side view shows a series of holes 

 right through the main trunk. Polyps completely retractile.

SOLENOCAULON EAMOSA, Hickson. 



A colony 8.5 cm. long agrees with Hickson's diagnosis in every point 

 except the greater size of the colony and the absence of all colouring-matter.
