officinalis, (common sponge,) irregular or subgio- 
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- 
minatious seem to indicate that they are an es- 
sential part of the organic structure of the ant- 
mal.

Dranches 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 
abundant in the upper lake on Catskill moun- 
fain, near the Mountain House. Has a fishlike
