SPONGES COLLECTED ON THE PRESIDENTIAL 

 CRUISE OF 1938 



By M. W. de LAUBENFELS 

 Pasadena Junior College 



In the summer of 1938 President Franklin D. Roosevelt made a 

 trip from San Diego to the Galapagos Islands, through the Panama 

 Canal (August 5), stopping at Old Providence Island in the extreme 

 western Caribbean Sea, and thence returning to Washington, D. C. 

 Thirteen species of Porifera were collected and preserved by Dr. 

 Waldo L. Schmitt, of the United States National Museum, Naturalist 

 to the expedition, with assistance from various members of the ship's 

 personnel. 



The sponges in the following annotated list are arranged in sys- 

 tematic order. A new species (No. 5 below) of the genus Mer- 

 riamium I take pleasure in naming M. roosevclti for the President of 

 the United States, whose interest in marine zoology made possible this 

 very successful expedition. In certain instances reference is made to 

 species which were also collected in the same area by the Hancock 

 Pacific Expeditions on the motor cruiser, J'elero III, under the 

 direction of Captain G. Allan Hancock, owner and sponsor.
