498 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



entirely covering and destroying the algai. The large openings (osciila) 

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

 varying from less than .05 to .10 of an inch or more in diameter. The 

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

 at the surface. This appears to belong to the genus Tedania. Another 

 species, apparently of the 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 FhyllopJiora, 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 algae, to the rough integument of Ascidians, to stones, shells, 

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