 American Museum of Natural History. Miss 

 O'ConneU has just completed and published a 

 memoir on the " Habitat of the Eurypterida" 

 and she will continue her investigations on the 

 conditions of existence of extinct inverte- 

 brates, using the evidence furnished by their 

 fossilized remains and by the characters of the 

 strata which contain them. 



The locality at Vero, Florida, from which 

 fossil human remains have been obtained was 

 visited in the latter part of March by Pro- 

 fessor E. W. Berry, Dr. R. T. Chamberlin, Dr.

 collection of fossil plants. The results will be 

 subsequently published.
