In addition to the hydrobiological work, several individuals of one amphibian 

 species were collected and a small collection of insects was made. 



Investigations in the fields of mammalogy and ornithology were almost entirely 

 restricted to field observations, because no men were available this year for full time 

 work in these fields. Complete notes were kept by the author, however, on his limited 

 obersvations of birds and mammals . 



Invertebrate and plankton collections were sent directly to the U. S. National 

 Museum, whereas the fish have been sent temporarily to the Woods Hole Oceanographic 

 Institution to be studied by Mr. Richard H. Backus, prior to ultimate disposition in 

 the U. S. National Museum. Amphibians and insects have been sent to Cornell 

 University.
