officinal! s, (common sponge,) irregular or subgto- 

 bular, porous, tough, lobed, woolly. Linneus 

 supposed that the large serpentine cavities in 

 this species were made by marine animals gnaw- 

 ing their passages into it ; though their regular- 

 ity and the prominences at their superficial ter- 

 minations seem to indicate that they are an es- 

 sential part of the organic structure of the ani- 

 mal. 



prolifera^ (branched sponge,) base flat, spread ; 

 branches numerous, subpalmate, ending in fin- 

 ger-like divisions. Grows in large bunches up- 

 on oyster shells, &c. ; sometimes six inches 

 high.

 sisting of numerous irregular branches. Very
