11 vurnosoRiA OCULATA. Plate XXV. 



Thin specimen was brought to me in November 1832. It in six 

 indies high, and spreading about six and a half inches. The utmost 

 spreading of the root does not exceed an inch in diameter ; and about 1111 

 inch above it, the stem diverges into two bought, the one larger than 

 the other; each spreading into numerous part*, by successive subdivision.*, 

 and frequently terminating by a fork at the extremity. 



The whole is of an umber colour, which, on drying, becomes of 11 

 dingy white. 



This sponge is not very rare in the Firth of Forth.
