The expedition sailed from San Diego July 9, on the 

 Mexican fisheries motorboat Tecate, Captain Victor Angulo 

 in command. It returned to San Diego August 16. Visits 

 were made to Guadalupe, San Martin, Cedros, San Benitos, 

 Natividad, San Roque, Asuncion, Magdalena, and Santa 

 Margarita islands; and landings on the peninsula of Lower 

 California were made at Ensenada, San Quintin, San Bar- 

 tholome Bay, and Abreojos Point. 



The primary purpose of the expedition was to determine 

 the present abundance and distribution of certain species 

 of marine mammals in those waters and to make collections 

 and study of the fauna and flora of the islands visited. 

 It was particularly desired to learn whether there are any 

 elephant seals, fur seals and sea otters left in the waters 

 about those islands. Each of these three valuable species 

 of marine mammals was at one time very abundant in those 

 waters, but through greed and indiscriminate killing they 

 had been reduced, it was known, to commercial, if not to 

 actual extinction. 



It is gratifying to know that the expedition found a very 

 satisfactory remnant of an elephant seal herd large enough, 

 if given proper protection, to enable that species to rehabili- 

 tate itself to its former abundance and commercial impor- 

 tance. An excellent moving picture reel was obtained of the 

 elephant seals. No fur seals or sea otters were seen. 



The expedition proved very successful and satisfactory. 

 Valuable collections of reptiles, birds, mammals, shells, in- 

 sects, and plants were made, and much valuable knowledge
