In addition to these, Gier reports a keeled green snake from 2 miles east 

 of Athens, Athens County, and two from 5 or 6 miles west of Gallipolis, 

 Gallia County. The Toledo Museum of Science has a specimen (TMS 

 2462) that was found at Walbridge, Wood County, near the Toledo Airport 

 in May, 1938. Higgins says that he views this record "with great suspicion, 

 since it was found in a railroad yard near some box cars." Here, in all prob- 

 ability, is another case of a southern snake being transported far north of its 

 range in produce, lumber, or some other commodity. 



Grobman (1941, 13) points out that the ranges of Opheodrys aestivus and 

 Opheodrys vernalis are complementary, the former being a lowland and south- 

 em form and the latter an upland and northern one. He quotes Netting as 

 stating that "in West Virginia aestivus is found in the valleys and vernalis in 

 the mountains." The ranges of the two species of green snakes are almost 

 mutually exclusive in Ohio, but there is some overlapping in the vicinity of 

 Cincinnati. In wooded ravines in Clermont County, aestivus is commonly 

 found in trees and bushes. The recently collected aestivus from Green Twp., 

 Hamilton County (UMMZ 98643), was found dead on the road; there was 

 a truck garden on one side of the road but no evidence of any woodland habi- 

 tats near-by. The only smooth green snake from the Cincinnati region was 

 taken, according to Dury, in the valley of the Little Miami River. Morse 

 (1904) reported vernalis from Hamilton County, but his specimen is no 

 longer extant. Future collecting may make it possible to show that the two 

 species are ecologically, if not geographically, isolated in extreme southwestern 

 Ohio, but the data at hand are too meagre to warrant any general statements 

 upon this subject. 



One of the snakes from Jackson Countv (OUVC 133) was obtained very 

 late in the season — on December 14, 1936. Hughes, who caught it, says it 

 "was found out of hibernation on a warm day." 



Twenty-two additional specimens of Opheodrys aestivus have been col- 

 lected in the past several years: thus, the number of individuals upon which 

 scale counts are now available has been slightly more than doubled. Statistics 

 for all forty-three (23 males and 20 females) may be summarized as follows: 

 Upper labials — 7 occurs seventy-two times, 8 eleven times, and 6 three times. 

 Lower labials — 8 occurs seventy times, 7 nine times, 9 four times, and 6 three 

 times. Preoculars — normally 1, but 2 on both sides of the head in three 

 snakes. Postoculars — normally 2, but 3 on one side of the head in two speci- 

 mens and 1 on both sides in two others. Anterior temporals — normally 1, but 

 2 on one side of the head in two snakes and 2 on both sides in another. Pos- 

 terior temporals — normally 2, but 1 on one side in one snake and on both sides
