HALICHONDRIA sp. 



The sponge consists of an irregular basal mass, from which a 

 tubular cylinder with thin fenestrated walls rises to a height of 

 five inches ; the tube is half an inch in diameter and open at the 

 summit. A small patch of tough dermal membrane, easily detach- 

 able, remains near the base of the tube. Texture rather tough. 

 Colour dirty yellow. 



Skeleton composed of a network of oxeote spicules, with primary 

 longitudinal lines of bundles about four spicules thick, the rest of 

 the network being very irregular and confused, and with unispiculate 

 meshes. Spongin apparently absent, the spicules being to some 

 extent supported by membrane. The flesh has been almost macerated 

 away. Spicules oxea, slightly curved, sharp-pointed, 348 x 15 //,.

The species appears to be new, but the specimen is in too bad 

 a condition to warrant a specific name being given.
