As a particular sorvey of the collections has not "been made, as hat 
a part of the year’s collections have so far been received, no attempt is 
made to present further fosults here. As stated above a nuraher of new 
records, and new species have unquestionshly been obtained, as well as some 
data on environmental conditions from sections of the South American coast 
where these are almost wholly lacking. It is espected that considerable now 
light will be thromi on the distribution of the crustacean elements of the 
South ilmorican invertebrate fauna. This hope has already been realized in 
part in the studies that Dr. Mary J. Rathbun has made on the Xanthid crabs 
contained in the first part of the 1925 collections. 
Aside frail the material returns of the expedition, the peisonal 
contacts established Ith scientific workers and institutions in South -^erica 
will undoubtedly prove to be of great value to the National Museum and the 
‘Smithsonian Institution.
