The Editor has received from Dr. D. Starr Jordan the manuscript 

 of a paper upon the Fishes of Formosa, which will shortly appear as 

 the Fourth Part of Volume IV of the "Memoirs" of the Museum. 

 From Professor P. P. Calvert of the University of Pennsylvania he 

 has received the manuscript of a monographic revision of the Odonata 

 of the South American continent, based upon the collections belonging 

 to the Carnegie Museum. This paper represents in part the results of 

 the labors of Professor Calvert upon the Odonata of South America, 

 which have extended over many years. The authorities of the United 

 States National Museum, the Museum of Comparative Zoology at 

 Cambridge, the Academy of Natural Sciences in Philadelphia, and 

 many others have kindly placed their collections at the disposal of 

 Professor Calvert, and he has thus had before him in the preparation 

 of this monograph all the available material existing in American col- 

 lections, and his report will undoubtedly become a classic work of 

 reference.
