240 THE AMERICAN MIDLAND NATURALIST 



On the basis of our present knowledge, the population of this snike in 

 Ohio is an intergrading one, and it should bear the designation Storer'ia dekayi 

 dekayi X wnghtorum. How far the intergrading area extends into adjacent 

 states is something that can be determined only by careful examination of many 

 large series of specimens. One could wish for a much larger Ohio sample, but 

 dekayi is such a common species in many localities that naturalists have paid 

 little attention to it. Also there is the fact that specimens are small, and 

 making scale counts upon them is tedious work. As a result, relatively few 

 have been preserved. New Ohio records are:

Among the new records are a few additional localities from relatively short 

 distances south and cast of the glacial boundary. There is evidence to indicate 

 that most, if not all, of these lie in filled valleys where .habitat conditions are 

 similar to those in the till plains and the glaciated plateau area and consider- 

 ably different from those that prevail throughout the uplands of the unglaciated 

 Allegheny plateau as a whole. Comment upon such valleys is included in the 

 discussioDs on Natnx kirtlandii (p. 230) and Thamnophis s. sauritus (p. 

 249), both of which snakes have distributions in Ohio that are similar in 

 some respects to that of Storeria dekayi. 



Field notes accompanying specimens of dekayi that were taken in the ungla- 

 ciated part of the state are incorporated in the paragraphs that follow. 



Carroll County: Buchanan, who has supplied the data below on the 

 geology of the region near his home, has seen a specimen from the Specht 

 Marsh (in the northeastern part of Washington Twp.), which is a poorly 

 drained area in the valley now occupied by Still Fork Creek. This valley is 

 the bed of a lake that was created when the glacial front advanced southward 

 to Big Sandy Creek and dammed the streams of the region. Silts and glacial 

 debris subsequently filled the valley of Big Sandv Creek to a depth of 200 feet 

 and the other valleys to a lesser degree (but with silt only). Both the ribbon 

 snake and the spotted turtle also occur in the Specht Marsh. They and Stor-
