found last year of the same generation, will furnish the basis of a 

 report now in preparation. 



No adult specimens of the second generation l-»ave as yet been 

 obtained, although many immature individuals of it were observed, 

 which should attain complete development during the year (1917). 

 The results to be shown by this second generation, probably the most 

 interesting one, are eagerly looked forward to. 



An unlooked for result was obtained on New Found Harbor Key, 

 where four hybrid specimens between the native Ccrioii iiicainim 

 and the transplanted Bahama stock were obtained.

The Florida tree snails, Liguits fasciatits, transplanted from 

 Brickies Hammock near Miami, to the grounds of the Commandant's 

 residence at Key West, and Garden and Loggerhead Keys, Tortugas, 

 have completely disappeared from these places, not even a trace of 

 a shell being found, thus stamping the experiment a failure. 



During the Cerion investigations, and while traveling on a slow 

 train between Key West and IMiami on Jvme 24, Dr. Bartsch kept 

 records of the birds observed. These are to be shortly published in 

 the Year Book of the Carnegie Institution, as his fourth annual list 

 of the birds observed in southern Florida. Eight species were added 

 this year, which had not been previously noted, bringing the total 

 so far seen to ninety-seven.
