varieties of land shells from all parts of the world, except New Eng- 

 land. His New England collection Mr. Winkley retains for study, 

 but he writes that he thinks in time it too ' will find its way to the 

 Museum.' The shells received are in excellent condition. Mr. 

 Winkley, as a member of the class of 1881, recalls with pleasure his 

 undergraduate work in the Museum, and gives the collection as his 

 contribution toward the twenty-fifth anniversary celebration of the 

 class. It is hoped that Mr. Winkley's gift will prove an incentive 

 to other graduates to associate their college work with the interests 

 of science and the Museum."- (From the Annual Report of the Cura- 

 tor, Museum of Comparative Zoology, 1905-1906.) 



THE MUMFORD COLLECTION or SEIELLS Through a bequest of 

 the late Mr. Henry Mumford, the Museum of the Brooklyn Institute 

 of Arts and Sciences has secured an unusually fine collection of 

 shells, comprising about 15,000 specimens, representing 2,400 species; 

 this will be known as the Phebe L. Mumford Collection. It was 

 originally brought together by Mr. Isaiah Greegor, for many years 

 a resident of Jacksonville, Florida, who made a special effort to se- 

 cure the best possible specimens. This makes the collection par- 

 ticularly valuable for a museum, since the shells are in their natural 

 condition, retaining the outer layer or ' epidermis," which is usually 

 removed to show the brilliant coloring beneath, a proceeding that 

 makes the shell " look pretty," but utterly destroys its scientific 

 value ; there are, however, series of shells cleaned and polished so 

 that the student and the lover of the beautiful may alike find what 

 they wish. 



Two years ago the Museum received a valuable gift of shells from 

 Mr. Julius Brunn, so that the division of mollusks is now very well 

 represented. ( The Museum News.}
