From drift on the beach, Pisco, July 7, 1908, Coker 465 р.р. 
The plants аге 4-5 cm. long and wholly unbranched, from a 
very long, slender, terete stipe, the thallus becoming flattened and 
1-6 mm. wide above. The narrower plants approach f. cylindracea 
in general outline. The cells average about 13 шіп diameter, though 
they occasionally show a maximum diameter of 2 5-27 и; the mem- 
brane isabout20u thick. The plantsdiffer from ordinary conditions 
of Е. intestinalis in their darker green color and in the rather more 
regular arrangement of the cells. They differ from Е. bulbosa in 
the long-attenuate unbranched stipe, the smaller cells, the thinner 
membrane, and the much less distinctly defined cell walls. 
Enteromorpha intestinalis has been reported from Callao by 
Montagne (Fl. Boliv. 5. 1839).

Dredged in Ancén Bay, in 9 fathoms, on a muddy bottom, 
Feb. 13, 1907, Coker до p.p. А fragment only, about 32 cm. long 
and 5-7 mm. wide, margins undulate-plicate or slightly crisped, 
membrane (double) about 28-33 u thick,—agreeing essentially 
with J. Agardh’s forma lanceolata. This species has been reported 
from the same general region (Island of San Lorenzo) by Piccone 
(Alg. Vettor Pisani 23. 1886). 
Enteromorpha compressa (L.) Grev. has been reported from 
Paita by Montagne (Voy. Bonite, Bot. Crypt. 3. 1846) and by 
Piccone [Mem. R. Accad. Lincei IVa. 6: —(10). 1889)
