NO, 2 DAWSON : MARINE RED ALGAE OF PACIFIC MEXICO 291 



its dichotomous, flabellate blades with rounded apices, its entire margins, 

 and large, scattered, rostrate cystocarps. The relatively thin blades and 

 the non-nemathecial tetrasporangia may also aid in identifying it. 



The plant referred to Callophyllis dissecta by Kylin (1941, p. 16, pi. 

 5, fig. 15) has nearly parallel upper segments and seems in this and 

 other respects to be a terminally proliferous example of C. obtusifoHa. 



Callophyllis edentata Kylin 

 PI. 29, fig. 76 



Kylin 1925, p. 34, fig. 18; Doty 1947, p. 175. 



Type: Holotype not designated, but represented by the specimen 

 illustrated by Kylin, probably in his herbarium at the University of 

 Lund, Sweden. An isotype in the Herbarium of the University of Cali- 

 fornia is dated July 22, 1924. 



Type locality: Dredged at a depth of 5-10 fathoms. Turn 

 Island, near Friday Harbor, Washington. 



Callophyllis filicina Setchell & Swezy 

 PI. 30, fig. 77 



Setchell 1923, p. 398. 



Type : Holotype is a tetrasporic specimen collected by N. L. Gard- 

 ner, 1913g, on sheet 77819 in the Herbarium of the University of Cali- 

 fornia, Berkeley. 



Type locality: Venice, California. 



Callophyllis filicina is reduced in this study under C. gardneri. (See

Callophyllis flabellulata Harvey 

 PI. 25, fig. 72 



Harvey 1862, p. 171; Kylin 1925, p. 34, figs. 15-16; Doty 1947, 

 p. 174. 



Type: Holotype not designated. Twelve syntype specimens of 

 David Lyall's collection, Feb. 1860, remain in the Harvey Herbarium, 

 Trinity College, Dublin, Ireland. A syntype is in the Agardh Herbarium 

 according to Kylin. A syntype, ex. Herb. Harvey, is in the HAHF.

 couver Island, British Columbia, Canada. 



Although Doty (1947) has reduced both C. crassifolia and C. mar- 

 ginifructa under C. flabellulata, and his decision may prove to be sound, 

 in this account C. marginifructa has been recognized. This has been done
