16 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 12 



made to the biological station and the excursion over the island and sur- 

 rounding shores on the Hancock Expedition of 1934. Although not able 

 to be present himself, the superintendent of the station, Mr. James Zetek, 

 arranged with the Panamanian employees to act as guides, with the result 

 that all the members of the party, and particularly the botanist, had a 

 very profitable time there. A large number of species of ferns was the 

 chief botanical harvest, and these have been deposited in the U.S. National 

 Herbarium and the herbaria of the Hancock Foundation and the Uni- 

 versity of Michigan. The identifications were made by the kindness of 

 Dr. W. R. Maxon of the National Herbarium.

The Hancock Expedition of 1934 went south from Is. Revilla Gigedo 

 to I. Clipperton, a small atoll of disputed ownership far at sea. No algae 

 were secured on this occasion, though Dr. Schmitt did get a very interest- 

 ing sample from the lagoon on another visit (Taylor 1939). Thence it 

 went direct to the Galapagos Is. for the major scientific work of the cruise. 

 The visits in 1934 to mainland stations were made on the return voyage, 

 but in order that the succession from north to south may be preserved 

 they have been treated in geographical rather than chronological order, 

 and the Galapagos observations will be placed last as a matter of con- 

 venience. In 1939 the Expedition went from Panama into the Caribbean 

 (Taylor 1942) and did not visit Pacific South American ports. 



The most northerly South American station visited by the Expedition 

 in 1934 was Bahia Utria. The country around the large harbor was in- 

 tensely interesting botanically, but the shores of the harbor itself were 

 very unproductive. Practically everywhere muddy or of mud-covered 

 rocks where accessible, the collections by hand along the shore yielded a 

 new Halymenia (H. utriana), crustaceous corallines, and a small Gelidi- 

 utn. On the higher rocks Bostrychia was seen, but apparently not col- 

 lected. In a stream the rocks were red with a fresh-water Hildenbrandia, 

 which was a very interesting find. Although considerable dredging was 

 done here at depths of 27-73 meters, no algae were secured. 



On the shores of the bay the muddy border was largely lined with 

 brush and cocoanut palms. Some very poor thatched huts were built close 

 to the water's edge, and there were a few people living there. In the woods 

 the growth was heavy, with a fine development of epiphytes : aroids, bro-
