ENTEROMORPHA 23 
Isla Asia, August 26, 1907, Coker 241 p.p.; from rocks in the 
surf, Mollendo, August 1908, Coker 565 p.p. 
No. 241 p.p., we infer from Suhr’s description and figures, is 
close to the type, which was attributed to Peru without definite 
locality. The plants are dark green, 3—9 cm. high, stipitate апа 
copiously or very sparingly branched near the base, the frond or 
its branches becoming 0.5-7.0 mm. broad above; the cells are 
large, 13-30 и in diameter in surface view, 28—40 и deep, mostly 
rectangular and in rather distinct rows below, becoming more 
rounded and irregular above, the walls thin, firm, and sharply 
defined. 
No. 565 p.p. is a lighter bluish green, 2-4 cm. high, with the 
frond or its branches rarely reaching a width of 1 mm., but in the 
rather bulbous stipitate base, in mode of branching, and in form, 
size, and arrangement of the cells is much like no. 241, though the 
chromatophore appears thinner, occupies relatively less of the 
cell, and often has a stellately lobed margin, while that of no. 241 
is usually subentire with a rounded or quadrate outline. 
J. Agardh (loc. cit.) in discussing the relationship of Entero- 
morpha bulbosa to E. compressa emphasizes the more sordid green 
color of Е. bulbosa аз a distinguishing characteristic. This might 
apply to Dr. Coker’s 241, but not to his 565, if we are correct in 
identifying that with Е. bulbosa. А better distinguishing char- 
acter, if one may judge from the specimens cited above, is to be 
found in the much larger and more regularly arranged cells of the 
Peruvian plant, the cells perhaps averaging to have about twice 
the diameter of those of Е. compressa.

bottom of our boat after voyage of one month from Callao." 
Sparingly proliferous near the Базе. Dr. Coker's 145c differs 
from the specimens that we have referred to Е. bulbosa in the much 
smaller cells, which are only about 5-15 4 in diameter, іп the 
thinner membrane, which is mostly 12-20 u thick, in the slender, 
reduced, more irregularly disposed branches, in the less sharply
