REPORT OF THE SECRETARY 33 



tlie excavations carried on under tlie auspices of the National Geo- 

 graphic Society at Pueblo Bonito, remained in the field for several 

 months and secured excellent collections and highly important in- 

 formation. Henry B. Collins, jr., conducted explorations at ancient 

 village sites in Mississippi, where valuable studies have resulted 

 from intensive work in the field. 



Biology. — Increase in the collections in the various divisions of 

 this department have equaled and in some cases have excelled those 

 recorded for the previous year. Of outstanding interest is the col- 

 lection of coleoptera and mollusks that came to the Museum by 

 bequest of the late Col. Thomas Lincoln Casey. The beetles alone 

 in this collection are estimated at approximately 90,000 specimens 

 representing 16,000 species of which 5,000 were described by Colonel 

 Casey and are represented by the types. 



The large collections presented by the National Geographic 

 Society as the result of expeditions in China by Dr. J. F. Rock and 

 Mr. F. R. Wulsin include a total of over 4,500 specimens of verte- 

 brates and 68,000 plants, a wonderful store of rich material that has 

 added greatly to the representation from that area, for, in addition 

 to a number of forms previQusl}'^ unknown to science, there are in the 

 collection man}^ species not before represented in this institution. 

 Additional collections from China have come through the continued 

 efforts of Rev. D. C. Graham in western Szechwan, which have added 

 vertebrates and valuable insects. China has been further represented 

 in our accessions by material collected by A. deC. Sowerby, pre- 

 sented through the continued interest of Mr. R. S. Clark. 



Mr. B. H. Swales has continued his important additions to the 

 collections of birds by the purchase of a considerable number of 

 species not previously represented including a number of rarities 

 from Madagascar. Further acquisitions through the interest of Dr. 

 Casey A. Wood have resulted in additional specimens from Fiji. 

 Dr. Hugh M. Smith, now in Siam, has begun presentation of 

 valuable material from a region almost unknown in our collections 

 and has included among other things in his first sending a highly 

 valuable lot of marine invertebrates. 



Valuable collections of fishes have come from the H. K. Mulford 

 Co., of Philadelphia. Certain important specimens have been pur- 

 chased for the collections of mollusks from the income provided 

 for that purpose by the Frances Lea Chamberlain fund. 



In the exhibition halls there was installed a new group of Rocky 

 Mountain goats prepared from material collected by Secretary and 

 Mrs. C. D. Walcott; the case represents a family of four with an 

 appropriate background of rockwork. A number of older mounts 

 of other mammals have been replaced by material prepared by
