NO. 2 DAWSON : MARINE RED ALGAE OF PACIFIC MEXICO 293 



from where Setchell obtained his description of the cystocarps of C. 

 filicina which are supposed to be distinctive in being "projecting" and 

 "subterminal on the ultimate laciniae." Curiously enough, a duplicate of 

 Gardner 1913g is at hand which was identified by Gardner, himself, as 

 Callophyllis gardneri! Both the holotype and this isotype correspond 

 closely in habit and structure with the tetrasporic and cystocarpic type 

 material of C. gardneri from the same locality (Venice). They differ 

 only in one recognizable way. The holotype of G. filicina has the tetra- 

 sporangia in a distinctly nemathecially modified cortex, while in the 

 C. gardneri isotype they are in an essentially unmodified cortex. How- 

 ever, the paratype specimen of C. filicina from La Jolla has non-ne- 

 mathecial tetrasporangia. Whether this difference is a real one is yet to 

 be determined. Meanwhile, because of the unsatisfactory status of the 

 type material of C. filicina, as pointed out above, it is considered best 

 to reduce that name under C. gardneri, despite page priority of the 

 former, and to adopt C. gardneri as the name for this entity.

Type: Holotype is N. L. Gardner 2291, July 1910, on sheet 

 651624 in the Herbarium of the University of California, Berkeley. 

 Two specimens are present, both apparently lacking cystocarps. 



Type locality: Dredged in about 8-10 fathoms of water, west of 

 Canoe Island, near Shaw Island, San Juan County, Washington. 



Callophyllis johnstonii Setchell & Gardner 



The type material of this species consists of three plants. Two of 

 these, a cystocarpic and an antheridial one, were figured by Setchell and 

 Gardner (1924, pi. 51, figs. A-B), although the antheridial one was 

 erroneously labeled "tetrasporic." These specimens are deposited in the 

 Herbarium of the California Academy of Sciences. The third specimen 

 is also cystocarpic and is deposited at the University of California. 

 Through the cooperation of these institutions the types have been made 

 available for examination and comparison in this study. When tran- 

 sections of the thalli were made it was immediately apparent that an 

 error was involved, for the large, thick-walled cells of the medulla were 

 found not to be "interspersed with fine filaments" as described by Setchell 

 and Gardner, but rather provided with numerous, slender, pit-connec- 

 tions. Clearly, the plants had been misplaced in Callophyllis. Notice of
