entirely covering and destroying tlie alg;e. The large openings (oscula) 

 are irregularly scattered over the surface and quite unequal in size, 

 varying from less than .05 to .10 o^an inch or more indiameter. The 

 texture is rather close when dried, showing a finely reticulated texture 

 at the surface. This appears to belong to the genus Te^mm m^. Another 

 species, apparently of tbe same genus, occurs with the last, and has the 

 same habits, but its color is pale buff, or yellowish white, and its text- 

 ure is much firmer and more compact. Another species, occurring with 

 the last two on the FhylloijJiora, at Watch Hill, forms small, irregular, 

 deep yellow masses, of a soft and somewhat gelatinous consistency. 

 Foraminifera of several species are abundant, attached to the fronds 

 of the red algre, to the rough integument of Ascidians, to stones, shells, 

 worm-tubes, &c., but they have not yet been identified.
