MUSEUM OF COMPARATIVE ZOOLOGY. 7 



on the terrestrial mollusks of the United States, which remains 

 to-day unexcelled. The manual, " The terrestrial air-breathing 

 mollusks of the United States and the adjacent territories of 

 North America," of her father, William Greene Binney, was pub- 

 lished as volumes four and five of the Bulletin of this Museum. 

 These volumes with the several supplements issued later, main- 

 tain the reputation of Amos Binney. 



Mrs. Earl's gift, the William Greene Binney collection, consists 

 of nearly nine hundred lots of pulmonate gasteropods with the 

 types and typical material illustrative of W. G. Binney 's studies; 

 though lacking large numbers of specimens of any form, its well- 

 selected series shows in admirable detail the variation and distribu- 

 tion of the species represented. 



During his studies of Palaeozoic Echini, Dr. R. T. Jackson 

 amassed a large series of specimens of recent forms. These he 

 has most generously presented to the Museum, and, though the 

 Museum's series of recent Echini is an especially large and com- 

 plete one, Dr. Jackson's donation contains many that are most 

 desirable additions, including all the Mesozoic and recent forms 

 figured in his monograph of the Echini (Memoirs Boston society 

 of natural history, vol. 7). There are also a large number that 

 can be used advantageously for exchanges. 



In the early years of this Museum its stores were enriched by 

 large and valuable collections gotten together by zealous mission- 

 aries in many parts of the globe. One of the notable instances of 

 this work was that of the Rev. M. M. Carleton. Mr. Carleton's 

 collections, received during the early seventies, were made almost 

 entirely about Amballa and Koolloo, India, and their value is 

 increasingly recognized each year. 



It is especially gratifying to record a similar service this year. 

 To the Rev. George Schwarb the Museum is much indebted for 

 many and most desirable additions to its series of reptiles and am- 

 phibians. Collected in western equatorial Africa, Mr. Schwarb's 

 specimens add a number of species previously unrepresented in 

 the Museum collections, and they are, moreover, in excellent con- 

 dition for study. 



In the name of the late Francis A. Pierce, Mrs. Pierce has most 

 kindly given the Museum a collection of skulls and horns of 

 ungulates, some of which have been mounted by Mr. Nelson and 

 are shown on the wall of the Divinity Avenue Entrance Hall. 



The Museum is indebted to Mr. L. J. de G. de Milhau for 

 another installment of Icelandic birds. These as well as previous
