MARINE FAUNA OF ST. ANDREWS. 
Lenralia granifera, Johnst.; Busk, Catal. p. 83, pi. 77. f. 2, 
pi. 95. f. 6 & 7. 
Abundant on the under surface of stones near low-water 
mark in considerable patches. The aspects of the old and 
new cells differ much. The new cells glisten like those of 
L. liyalina , have a number of opaque white granules, a D- 
shaped aperture, and a distinct mucro ; the transverse wrinkles 
of the cells are also apparent; and in some very new ones the 
granules are also glistening and hyaline, and show the per¬ 
forations. In the old cells the walls are opaque, whitish, or 
yellowish, the granules still more opaque, perhaps larger, but 
less defined and beautiful. 
Lepralia hyalina, L. ; Busk, Catal. p. 84, pi. 82. f. 1-3, 
pi. 95. f. 3-5, pi. 101. f. 1 & 2.
