In 1896 Germanos (Gorgonaceen von Ternate) investigated this genus and 

 ranked the six known species under two sub-genera, viz., Sderosolenocaulon. and 

 Malacosoletiocaulon. He distinguished the two groups chieHy by the presence 

 or absence of a stalk. Hick,son in the "Alcyonaria of the Maldives," Part I., 

 1902, pointed out that this classification is unsatisfactory, inasmuch as it is yet 

 doubtful " whether there are any specimens of SoleHocnidon without a stalk ". 

 All the specimens we have examined have shown a stalk. The usual habitat 

 of Solenocaalou is on sandy or muddy bottom in which the colonies are em- 

 bedded for several inches by a basal stalk. 



Another feature which merits attention is the fusion of the spicules to form
