4 ANNUAL REPORT OF THE 



study of coral reefs, and in Samoa, he made a large collection of 

 igneous rocks and investigated the volcanic geology of the several 

 islands visited. 



Mr. W. S. Brooks made considerable collections in the Isle of 

 Pines, and later in the year transferred his field of work to extreme 

 southern Florida, where, in cooperation with Dr. Barbour, he col- 

 lected reptiles and mollusks, among the latter a very large series of 

 Liguus. 



Mr. George Nelson of the Museum staff spent several months in 

 Florida collecting mammals, reptiles, and fishes in and about 

 Sebastian; his work included, in addition to the material for the 

 research collections, a number of vertebrates for exhibition. 



Always fortunate in having much voluntary service, the Museum 

 records its obligations for assistance in several departments : — to 

 Messrs. F. H. Kennard and T. E. Penard (ornithological depart- 

 ment) ; to Dr. G. M. Allen (herpetological collections) ; to Prof. 

 W. M. Wheeler and Mr. A. C. Kinsey (entomological depart- 

 ment); to Miss E. B. Bryant (arachnids); and to Dr. R. M. Field 

 and Mr. T. H. Clark (fossil invertebrates). 



The Harris collection of Tiger beetles (Cicindelidae) constitutes 

 the year's most important accession. Edward Doubleday Harris, 

 the son of Thaddeus William Harris, the author of the classic, 

 Insects injurious to Vegetation, and also Harvard's Librarian 

 1831-1856, died in Yonkers, N. Y., 2 March, 1919. Born in 

 Cambridge, 20 September, 1839, a latent love of nature was 

 developed somewhat late in life, as his manhood was engrossed 

 with large financial trusts and his principal inherited interests were 

 historical and genealogical. Selecting a single family of beetles for 

 an avocation, Mr. Harris took up their study with great enthusi- 

 asm, and by his personal work, a careful system of exchanges, and 

 the judicious purchase of material, got together a very large and 

 valuable series of species from all parts of the world. The entire 

 collection is in excellent condition, well identified, thoroughly 

 catalogued, most neatly relabeled and with the original labels in 

 all cases carefully preserved. In connection with his work, Mr. 

 Harris carried on an immense correspondence, which, with his 

 notes and unpublished illustrations, was bequeathed with the 

 collection to the Museum.
