NO. 1 TAYLOR: PACIFIC MARINE ALGAE 5 



Eisenias were noted, and in addition particularly Colpomenia sinuosa i. 

 deformans, Taonia Lennebackerae, Cystoseira osmundacea, and some cor- 

 allines. No dredging was done here which yielded any algae, and there 

 was little washed ashore. 



Point Hughes, Bahia Santa Maria 



The party from the Hancock Expedition of 1934 landed at Point 

 Hughes inside of Cabo San Lazaro, to the north of Bahia Santa Maria. 

 The shore is of fissured and intrusion-lamellate rocks, forming rocky spurs 

 alternating with sandy or bouldery beaches, backed by sheer cliffs of 20- 

 50 feet in height. Two benches at elevations of approximately 15 and 30 

 feet above extreme high tide line showed rock fragments and fossil shells 

 in vast abundance, apparently cemented by calcareous algae of an earlier 

 period, and the ground near the top of the cliffs was strewn with the fossil 

 operculae of mollusc shells. 



In the intertidal zone there were good tide pools between the rocks, 

 with an abundance of various stages in the development of young Eisenia 

 arbor ea, C odium, Dictyotas, and Padina Durvillaei. Washed ashore there 

 was a considerable mass of algae, which yielded numerous fully developed 

 specimens of the Eisenia, a quantity of Porphyra naiadum on Phyllo- 

 spadix, and Hypnea Johnstonii. Some dredging was done between 18 and 

 73 meters' depth, and this gave in particular Nitophyllum uncinatum, but 

 no great variety of algae. 



Nayarit, Mexico 



IsLA Isabel^ 



No mainland landings were made in this province by the 1934 and 

 1939 Hancock Expeditions, but both of them stopped at the little I. Isabel. 

 This island is of only very moderate height. The shore is partly sandy, 

 partly of volcanic rock. It is a good nesting island, particularly for boobies 

 and for frigate birds. It is also the station for a small group of Mexican 

 shark-fishermen, who erect a flimsy shelter and spend a few months of the 

 year there. Interesting though the island was on these accounts, it yielded 

 little in the way of algae. There was a little Ahnfeltia on the surf -beaten 

 rocks near high water, some small intermingled, matted forms, and little 

 else. Dredging did not furnish any additional records.
