paid to 87 of the 88 counties of Ohio; locaUty records are available from 

 every county. 



Most of the field work was accomphshed week ends and with Toledo (the 

 writer's residence) as the base. It was customary to leave Friday evenings, 

 drive the greater part of the night, collect from dawn to dark Saturdays and 

 Sundays and return home Sunday nights. Vacation periods, holidays, and 

 such business as attending meetings of the Ohio Academy of Science provided 

 additional opportunities for collecting. Many of the localities were visited 

 on numerous occasions and at different seasons and from the more productive 

 ones considerable information has accrued. A number of representative local 

 collections were made by interested persons in various parts of the state who 

 either presented their material to the writer or made it available to him for 

 study. 



In the course of the work many more specimens came to hand than it 

 was possible or practical to preserve. Surplus material was liberated, placed 

 on exhibition in the Toledo Zoological Park or traded to other zoos. How- 

 ever, all rare or unusual specimens and the great majority of those represent- 

 ing new localities were preserved, the bulk of them in the collection of the 

 Toledo Zoological Society. 



In addition to making studies upon the specimens found in the field an 

 effort was made to examine Ohio reptiles in the leading museums of the 

 country, and to visit as many of the college museums and private collections 

 in the state as time and circumstances permitted. A list of the institutions 

 and individuals from whom material was borrowed and studied is given imme- 

 diately below. The initials in parentheses are those used to designate the 

 various collections in the lists of locality records published in the present text. 

 DOR signifies that the specimen was found dead on the road but for some 

 reason was not preserved.
