124 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 12 



Myxophyceae^^ 



A full account of the Myxophyceae of the 1934 Hancock Expedition 

 has already been published (Drouet 1936). There were not enough 

 records deriving from the 1939 Expedition to justify a special paper on 

 the Pacific collections. However, both the Caribbean and the Pacific 

 sections of this Expedition did secure Myxophyceae, and Dr. Drouet 

 kindly supplied the data for separate reports on the two phases of this 

 trip. The first part was incorporated in the paper already published on the 

 Caribbean Marine Algae of the Allan Hancock Expedition, 1939 (Tay- 

 lor 1942). The second part follows here, where it is appropriate to list 

 the blue-green algae of the Pacific portion of the 1939 Expedition, but by 

 including references to the 1936 report the account is made far more rep- 

 resentative of the collections. — w.r.t.
