before on this side of the Gulf. This particular specimen, by the way, is the 
first of the species to find its way into the collections of the National 
Museum. 
At Socorro Island, July 20, some of the best fishing of the cruise 
was experienced. Leopard groupers, spotted cabrillos, California yellowtails,

and also several blue crevallys were taken. The President landed the^prize 
of the day. It was a blue crevally establishing a record weight for the species 
38 pounds.’ Prom along the shores of Braithwaite Bay a small mullet, Mugil 
setosus . was secured. It is the first of its kind that the National Museum 
ever received. 
July 21st, an eventful day, and one of the high lights of the cruise. 
A landing was made on Olipperton Island, the only true coral atoll in eastern 
Pacific waters. Dr. Wetmore had long been anxious to obtain a study series of 
the birds frequenting this isolated and seldom visited coral island. Thirty-two 
birds were obtained, as well as a fair sample of its marine fauna. At least 
one new species of shrimp was discovered here. Dr. William Randolph Taylor, of 
the University of Michigan, who has prepared a report on the algae secured for 
publications, writes, "The Olipperton Island collections are unique, for land- 
ing on this isolated atoll is especially difficult.* 1 He states further that 
he found the jars of mixed algae from the lagoon very surprising, inasmuch as he 
had assumed that the water was salt by seepage or other admixture from the sea. 
The plants he found indicated 11 on the contrary, that it is at least nearly fresh 
at any rate near the surface and in the shallows, though probably heavily 
polluted with nitrogenous matter from the bird colonies. The bulk of the 
material was of Myxophyceae, which is appropriate under such conditions and 
apparently great masses of Ly ngbya versicolor must have been present at least 
near the shore. This is not a definitely marine species. With it were other
