HENRY W. WINKLEY. 



The Rev. Henry W. Winkley, rector of the Calvary Episcopal 

 church, Danvers, Mass. died at his home, February 4, 1918. 

 Born in Boston, Mass., March 24, 1858, he graduated from 

 Harvard University in 1881 and from the Episcopal Theological 

 School in 1884. He was ordained rector of Grace Episcopal 

 church, Newton, Mass. in 1885 and later was rector of churches 

 in St. Stephens, New Brunswick, Saco, Me., andBranford, Conn. 



Mr. Winkley had for many years taken a great interest in the 

 study of mollusks, contributing since 1891 over thirty articles to 

 the pages of The Nautilus, giving interesting accounts of his 

 various collecting trips along the New England and Canadian 

 coasts, with many useful hints as to methods of collecting. He 

 described three new species, Caecum johnsoni, Pyramidella bartschi 

 and Odostomia leathering while a number of species were named 

 in his honor. His entire collection of shells went to the Museum 

 of Comparative Zoology, Harvard University. 



He was a most enthusiastic and careful collector, specializing 

 on New England mollusks, his favorite places for collecting be- 

 ing Woods Hole, Mass. and Eastport, Me., although he has col- 

 lected at most of the favorable collecting grounds along our 

 coast. He also enjoyed collecting the small fresh-water species 

 and was an expert in the use of the sieves, obtaining Sphaeriidae
