190 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 3 



In Phycological Contributions VII, 1924, Setchell and Gardner pre- 

 sented the name Meneginiella Brandegeei for an undated specimen of 

 Brandegee's collection from La Paz. 



N. L. Gardner published in 1927 (New Rhodophyceae from the 

 Pacific Coast of North America VI) two new species from a collection 

 of D. T. MacDougal made at Puerto Libertad, Sonora, in November, 

 1923. Another small collection was made by MacDougal in May of the 

 same year, some specimens of which are mentioned for the first time in the 

 present account. 



In the quantity of material secured by J. T. Howell of the 1932 Zaca 

 Expedition of the California Academy of Sciences are some specimens 

 taken from the waters of the Cape region of Lower California. These are 

 included in the present paper. 



Waldo L. Schmitt obtained in 1938 a few algae from dredgings off 

 the Cape of Lower California. These were accounted for by W. R. Tay- 

 lor in 1939 (Marine Algae of the Presidential Cruise of 1938). 



In addition to the author's extensive collections made in the winter 

 and summer of 1940 and described below, material from this report has 

 been made available by several other contributors. Principal among these 

 other collections is that made by Dr. Francis Drouet and Mr. Donald 

 Richards of the Field Museum Expedition to Sonora in the winter of 

 1939. E. F. Ricketts of Pacific Biological Laboratories contributed some 

 samples from Puerto Refugio obtained in April, 1940. A few were 

 brought in by J. Wyatt Durham of the Scripps Institution of Ocea- 

 nography Expedition of the Fall of 1940. Lastly, a small but valuable col- 

 lection was made by Dr. John Poindexter of Stanford University at 

 Punta Penasco, Sonora, in the spring of 1941. 



All of the above-mentioned collections from the Gulf of California, 

 excepting part of those of Diguet and those of Schmitt, have been ex- 

 amined in the preparation of this report. 



Recent Collections of the Author 



In January of 1940 the writer was given the unique opportunity of 

 accompanying the Allan Hancock Expedition from The University of 

 Southern California as marine botanist. It was a splendid chance to visit 

 the Gulf of California in winter and with such equipment as would be 

 most effective in securing an unprecedented quantity of algal material. 

 Winter collections had not been secured from the area before, and, 

 moreover, a visit had never been made by an investigator primarily in-
