and authenticated collections in California, he sent most of his new 

 species to more favored workers for description. Dr. Carpenter says 

 of the species collected by Dr. Cooper : " The diagnoses . . pub- 

 lisd in the Proc. Cal. Ac. N. S. . . . should be credited to the 

 zealous zoologist of the survey, rather than to the mere artist-in- 

 words who endeavors to represent their forms to the reader." Dr. 

 Cooper described a few species collected by other workers in the 

 field, but of these there is no enumeration at hand. 



Dr. Cooper was a man of noble character and kindly disposition. 

 He was tall and slender, not very fluent in conversation unless the 

 topic under discussion was one of special interest to him. Many of 

 the younger students of zoology in California remember with grati- 

 tude his aid so freely given them in their studies. Since his death, 

 besides extended notices in the daily papers, there have appeared a 

 memorial by AVm. H. Dall in Science for August 15, and one by 

 \V. 0. Emerson, together with a list of ornithological papers, in the 

 current number of the Condor. The last is the Bulletin of the 

 Cooper Ornithological Club and contained in its first issue, 1899, a 

 much longer account of Dr. Cooper's life work. A partial list of his 

 conchological papers will be found in Bulletin 4, California State 

 Mining Bureau. The present portrait is from a photograph taken 

 in 1865, and was sent to the writer by Mrs. Cooper, who still lives 

 in Hay wards. WILLIAM J. KAYMOND.

Mr. Nakada, who collected so successfully in the Bonin Is. 

 (Ogasawara-jima), has now gone into western Hondo, through the 

 provinces Echizen and Kaga, and continuing northward will collect 

 in Noto and Sado Island. Among many other interesting discov- 

 eries, he lias found Sphyradium edentalum Drap. (new to eastern 

 Asia), Bifidaria, piicidens Bs. (described from India), magnificent 

 specimens of Eulota (Euhadra) senckenbergiana, one of the finest 

 helices in the world, and many other beautiful shells.
