204 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [498] 
entirely covering and destroying the alge. The large openings (oscula) 
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 bas the 
same habits, but its color is pale buff, or yellowish white, and its text- 
‘are is much firmer and more compact. Another species, occurring with 
the last two on the Phyllophora, 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 algze, to the rough integument of Ascidians, to stones, shells, 
worm-tubes, &c., but they have not yet been identified. 
List of species inhabiting the stony and rocky bottoms on the open coast.
