12 DICTYOTACEAE 
Capén, six miles from ocean; density 1022-24; Feb. 2, 1908”; 
region of Tumbes; Coker 344 p.p. 
Segments tetrasporic, sometimes 4-6 mm. broad but often 
only 1.5-2 mm., 82-95 u thick; apices obtuse; surface cells 14-50 и 
X 10-25и. Тһе segments аге sometimes as narrow as those of 
the plants currently referred to Dictyota Fasciola* but they are less 
attenuate and are not at all twisted. 
Dictyota dichotoma has been reported by Montagne (Fl. Boliv. 
34. 1839) from Cobija, once in Peru but now in Chile.

* Dictyota Fasciola was originally founded, in part at least, on Fucus Fasciola 
Roth and the name is currently written “‘ Dictyota Fasciola (Roth) Lamour." But 
scription and as is shown by his original specimens, is what J. Agardh long afterwards 
ibed as Dictyota repens and later made the type of his new genus Dilophus. 
Under the prevailing rules of nomenclature the specific name Fasciola should replace 
repens and the legal name of the type of Dilophus becomes 
Dilophus Fasciola (Roth) comb. nov.

Under the “American Code" the “Dictyota Fasciola” of recent authors requires ` 
а different specific name, though possibly no other is demanded under the '' Vienna 
Rules," and «ће “ Brussels Amendments." А name that satisfies all requirements is 
liches Naturhistorisches Museum in Oldenburg is, in general, in excellent condition. 
The algae are in Roth's original species-covers inscribed on the outside (first page) | 
with name of class, genus, and species. The second page of the cover bears the 
generic and specific names, diagnosis, synonymy (if any), habitat, and date of col- 
lection or acquisition by Roth. Та the case of Fucus Fasciola, the species is repre- 
sented by several loose specimens in an attached pocket. The opposite (second) 
page of the cover is inscribed with the name, diagnosis, and “1794. Inter Fucum 
Helminthochorton legi.”
