2 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 12 



1902, p. 77) ; some algae were included, and these were reported upon 

 by Farlow (1902, p. 89), this having been the first significant collection 

 of algae made here. Following, we recognize the St. George Expedition 

 where Dr. Cyril Crossland (1927) collected some algae, perhaps alto- 

 gether coralline algae from Panama and the Galapagos Is., which are 

 reported by Mme. P. Lemoine (1929). Unfortunately, the Astor Expe- 

 dition of 1930, on the yacht NourTnahal, though it did good work among 

 the vascular plants, apparently did not produce any algae (Svenson 1935, 

 1938). The Templeton-Crocker Expedition of 1932 on the yacht Zaca 

 did much better. Dr. J. T. Howell making considerable collections here 

 and to the northward, which have been reported upon by Setchell 

 (1937b) and by Setchell and Gardner (1937). Dr. W. L. Schmitt on 

 several occasions collected algae in the islands, and at other places within 

 the range of this report, but these materials are here referred to for the 

 first time. These all taken together, however, were not enough to justify 

 much analysis with respect to either the composition or the relationships 

 of the Galapagos marine flora. 



Conditions on the mainland have been even less satisfactory than on 

 the Galapagos Is. Just south of our territory we have Howe's (1914) 

 paper on R. E. Coker's Peruvian marine algae. There are hardly any 

 references to Ecuadorean or Pacific Colombian marine algae. There are 

 very few recorded species from Panama, chiefly those of Lemoine (1911). 

 For the coast north to Mexico again there is apparently nothing, but here 

 we have the important but brief paper of J. Agardh (1841), where 

 several new species are described. The outlying Is. Revilla Gigedo 

 yielded a number of algae to the California Academy of Sciences Expe- 

 dition, and these, collected by H. L. Mason, have been studied and the 

 flora analyzed by Setchell and Gardner (1930). The Gulf of California 

 has fared somewhat better. Hariot (1895) listed a very few species, and 

 later Howe (1911) a greater number on the basis of collections made at 

 La Paz by G. L. Vives. The materials assembled on the California 

 Academy of Sciences Expedition by I. M. Johnston, T. S. Brandegee, 

 and W. E. Bryant, and by Dr. and Mrs. Marchant, were much more 

 ample, and they were reported upon by Setchell and Gardner (1924); 

 a further study by E. Y. Dawson appeared in 1944. Northward on the 

 peninsula of Baja California small collections have been made and several 

 species reported, especially in scattering notes by Setchell and Gardner, 

 but there is no assembled account of them. Beyond the sources of our 

 collections to the north, the coast comes within the range of resident 

 botanists and, while much remains to be done, it is relatively well known.
