THE NAUTILUS. 



ments in geology and botany, was a good all-round zoologist 

 and had a lively and unaffected interest in the work that any 

 of his friends might be carrying on in that department. It was 

 his kindly habit in his travels about the country to preserve 

 any specimens that he came across that seemed to him likely to 

 be of interest to any of his zoological friends. It will be re- 

 membered that the conchologists owe to him the rediscovery of 

 the long lost Planorbis multivolvis Case, (Naut., XXI, p. 16), 

 and also the little Lymncea davisi Walker, (Naut. XXII, p. 

 17), which bears his name. 



In the spring of 1911 Dr. Davis' professional duties took him 

 to Florida and while there he collected quite a number of 

 samples of u drift," which in due time came into my possession. 

 Several of the localities represented in the collection, such as 

 Maimi and St. Augustine, have already been reported upon by 

 previous collectors and there seems to be no occasion to dupli- 

 cate their work, but quite a number of the places visited by Dr. 

 Davis have not been covered by any of the previous collectors 

 in Florida and a record of the species found by him seems 

 worthy of publication as a contribution to the distribution of 

 the Mollusca along the east coast of the state. 



I am indebted to Dr. George H. Clapp for the identification 

 of the Gastrocoptas and Vertigos.
