" This curious sponge is stiiF and somewhat elastic ; the interior 

 part is ligneous, striated longitudinally, and which is always bare 

 at the ends of the ramifications, where it seems to be composed 

 of numerous fibres that frequently split and divide into fascicles : 

 the spongy or exterior part is of a fine texture : colour pale yd- 

 low-brown. 



" This singular species, which appears to be undescribed, I 

 first noticed in Mr Dover's cabinet of British shells, chiefly 

 found at Weymouth. I have since taken a larger and more per- 

 fect specimen on the coast of Devon, measuring nearly five in- 

 ches in height." Montagu.
