J. B. QTJINTARD. 



It is with great regret that we iearn of the death of our old cor- 

 respondent, Mr. J. B. Quintard, winch occurred at his home near 

 .Silver Lake, Shawnee county, Kansas, on December 17, 1899. 



Born at Norwalk, Connecticut, October 21, 1839, he moved with 

 his parents to Knox county, Ohio, in 1847. In December, 1859, he 

 married Miss Madeline I. Watkins, and in May, 1860, they moved 

 to Kansas, where he selected a site on the open prairie and made a 

 home, which he occupied until his death. 



He was a great lover and careful observer of nature, and early 

 took up the study of Conchology. By his own labor in collecting 

 and exchanging, he got together a large collection of shells, and 

 especially of the land and fresh-water specie?. Mr. Quintard was 

 known by correspondence to most western collectors of fresh- water 

 shells, especially the Unionida. 



GENERAL NOTES. 



NOTE ON VITREA RHOADSI Pils The distribution of this species 

 would seem to be much more extended than was indicated when first 

 described (NAUT. XII, 101). I have specimens from Traverse City 

 and Charlevoix in this State, and Dr. R. J. Kirkhmd has recently 

 discovered it in Ottawa county, which would indicate a general dis- 

 tribution through the western part of Michigan. It has not as yet 

 been noticed in any of the eastern counties. I have also specimens 

 from County Carlton, Ontario ; Amherst, Mass., and Orange county, 

 Va., which extend the range much further to the north and east than 

 indicated by Mr. Pilsbry. BRYANT WALKER. 



NOTE ON THE HABITS OF LIMN^A MIGHELSI W. G. Binn. 

 Extract from a letter of Dr. R. J. Kirkland : " I made a visit to 

 Crystal Lake, Benzie county, Mich., in July and again in October. 

 Along the shores are thousands of dead Limncea mighelsi'W. G. Binn.,
