branches are longer than in most other specimens. The secondary branches 

 are typical. On these the verrucas arise mainly on the ventral surface thus 

 approaching somewhat to A, but on the main stalk they occur scattered irre- 

 gularly, not in clusters as in A. The verructe are small and dome-like. The 

 anthocodia^ are large and have an armature similar to A. 



Locality : Andamans, 20 fathoms. 



Previously recorded from Ternate. 



From the Wood-AIason Collection Miss Harrison ' has recorded two species 

 of Solenocaulon, as follows : — • 



" Solenocaulon tortuosum. Gray. 



" In the collection made by the Trustees of the Calcutta Museum this species 

 occurs in three varieties : — 



" In variety A, the lateral branches are short and come off in pairs on 

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

 beyond conical calices. 



" 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 ; calices 

 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. 



" Hab. : Bay of Bengal. 



"Solenocaulon ramosa, Hickson. 



" A colony 85 cm. long agrees with Hickson's diagnosis in every point except 

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

 ''Hah.: Bay of Bengal."
