currency, the firm continuing to make paper for the government 

 up to 1875. Mr. Willcox was in the Pennsylvania militia dur- 

 ing the Civil War, and attained the rank of colonel. 



On retiring from business Mr. Willcox took up the study of 

 mineralogy and geology, and during his frequent visits to 

 Florida became greatly interested in the geology of that State. 

 In the spring of 1886, under the auspices of the Wagner Free 

 Institute of Science, he organized with Prof. Angelo Heilprin of 

 the Academy of Natural Sciences, an expedition to explore the 

 gulf coast of Florida. Leaving Cedar Keys and proceeding 

 south, they examined the silex beds of Tampa Bay, and in as- 

 cending the Caloosahatchie to enter Lake Okeechobee. dis- 

 covered the Caloosahatchie Pliocene. An account of this ex- 

 pedition appeared in Transactions Wagner Free Institute, 

 Vol. I. In company with Dr. Wm. H. Dall, he again visited 

 these beds in the spring of 1887, and with the writer in 1888 

 made another trip to this and adjacent streams, making large 

 collections to aid Dr. Dall in his great work on the Tertiary 

 Fauna of Florida, also published in the Transactions of the 

 Wagner Free Institute (Vol. Ill, six parts, 1654 pages, 60 

 plates, 1890-1903). In the work of obtaining additional 

 material in other southern states and in many ways assisting 

 Dr. Dall and others, he took great pleasure. On the various 

 collecting trips he always obtained many undescribed species, 

 of which some sixteen have been named in his honor. He 

 made a large collection of Miocene and Pliocene shells and 

 specialized on the genus Busy con (Fulgur) both recent and 

 fossil. This collection he presented to the Academy of Natural 

 Sciences. 



For many years Mr. Willcox was Honorary Curator of the 

 Isaac Lea collection of Eocene fossils at the Academy of Natural 

 Sciences of Philadelphia. He was Chairman of the Committee 

 on Museum of the Wagner Free Institute, and always took the 

 greatest interest in the development of both institutions. A 

 warm friend of Dr. Isaac Lea and Dr. Joseph Leidy, he lived 

 to see the scientific work and progress of practically two gener- 

 ations. He is survived by a son, Mr. C. Percy Willcox, of 

 Philadelphia. C. W. JOHNSON.
