Family Cornulariidae. 

 Sympodium indicum, sp. n. 



A specimen forming a complete tube round a hollow 

 vegetable axis ; the granular greyish-white ccenenchyma is 

 thickly covered with large polyps irregularly arranged ; the 

 spicules are rough warted spindles and quadriradiate forms. 



Locality. Andaraans, 2G5 fath. 



Sympodium incrustans, sp. n. 



A large specimen encircling a fragment of the stem of a 

 plant ; the whole surface of the membranous stolon and of 

 the large polyps is covered with warty spindles and rods, 

 many of which are visible to the naked eje ; the polyps are 

 mostly in groups of two or three. 



Locality. Andamans, 371 fath. 



Clavularia decipiens, sp. n. 



Tmo specimens of a remarkable and difficult form seem 

 referalde to the genus Claviduria. They envelop and almost

70 and 110 mm. in length, probably the flinty fibre of a y 



glass-rope sponge). The coenenchyma is thin and consists 

 mainly of a felt work of spicules. The polyps, including 

 the retracted tentacles, have a length of 3 mm., and are
