expedition he was aided by a grant from the National Geographical 

 Society and by contributions given by a number of friends of science, 

 whose generosity is deeply appreciated. 



The expedition to the northern shores of Lake Superior undertaken 

 by the botanist of the Museum, Mr. O. E. Jennings, during the past 

 summer and fall, yielded a very large return in the form of carefully 

 selected specimens. Dr. Jennings has in course of preparation a report 

 which it is believed will embody much information touching the 

 ecology of species and their geographical distribution. 



Mr. O. A. Peterson was engaged during the summer and early 

 fall in making collections of Eocene mammals in the Uinta beds of 

 Utah. He reports himself as having been very successful in securing 

 skeletons, in some cases quite complete, representing genera hitherto 

 only known by fragments, and some which have not hitherto been 

 known or described. He left his collections in the care of Mr. Douglass 

 to be forwarded to the Museum at the same time that the remains 

 obtained in the dinosaur quarry are shipped in to the Museum. 



It was a great pleasure a few weeks ago to meet Mr. Albert I. Good, 

 who upon his return from West Africa brought with him a large 

 collection of insects and a collection of small mammals from Benito. 

 West Africa. We have also received a considerable number of 

 coleoptera collected by Dr. H. L. Weber in Kamerun. The entomo- 

 logical collections are constantly growing. 



We are deeply indebted to Mr. H. J. Heinz, who has consented to 

 deposit with the Museum as a loan for the coming year his entire 

 collection of ivory carvings, which is one of the largest and most 

 beautiful collections of its kind in existence on this side of the Atlantic. 



Dr. Arnold E. Ortmann during the past season made two ex- 

 cursions to the headwaters of the streams flowing east and west 

 from the central mountain ranges of Virginia and West Virginia. 

 He was particularly foitunate in obtaining near the type locality 

 specimens of two species of Unionidae originally found by Professor 

 E. D. Cope and described by Lea, which up to this time have been
