65172); 3 mi. N of Rarden (OSM 900); Shawnee State Forest (WED 254). VlN- 

 TON County: S of Lake Hope (OUVC 1864); Zaleski State Forest (OSM 490; 

 OUVC 1834). 



The following reports (from Buchanan, Gier, and Leete) may be added to the 

 list: Athens County: Athens; Stroud's Run, 3 mi. NE of Athens. HocKiNG Coun- 

 ty: Conkle's Hollow. Jefferson County: The valleys of Brush Creek and Yellow 

 Creek from the vicinity of Bergholz to the Ohio River. PiKE CoUNTY: Benton Twp. 

 (Camp Pike). Ross County: Chillicothe; Colerain Twp. (Pine Lake in Tar Hollow 

 Forest); Franklin Twp. (Stoney Creek in Scioto Trail Forest). SciOTO CoUNTY: 

 Union Twp. (Copperhead Tower in Shawnee State Forest). 



The copperheads from Jefferson County furnish a notable, but not unex- 

 pected, extension of range. This snake probably is locally common throughout 

 most of unglaciated Ohio, although it is interesting to note that all the known 

 records in the extreme eastern part of the state are from close to or east of th: 

 Flushing Escarpment. 



Among the specimens collected recently there are several that are excep- 

 tionally dark in coloration. A male from Pike County (DPLM 105.42), 

 that measures 890 mm. in length, is heavily stippled with grey and brown and 

 is one of the darkest snakes of this species I have ever examined. 



Sistrurus catenatus catenatus (Rafinesque) 

 Eastern Massasauga 



(Page 112; maps 27 and 65; plate 14, fig. 2 and plate 15, fig. 1) 



Evans and Gloyd (1949) have shown that catenatus and its western sub- 

 species, tergeminus, intergrade in Missouri and that the species does not occur 

 in the Ozarkian uplift. Hence the general range map (page 114) should be 

 amended to show catenatus terminating in north central Missouri instead of in 

 eastern Kansas and Oklahoma. New Ohio records are: 



Ashtabula County: Lake Cardinal (CMNH 43); Rome Twp. (CMNH 54-5, 

 154; CZP 4). Cuyahoga County: 12 mi. SW of Cleveland (TMS 2-^63. 2466). 

 Fayette County: Western Concord Twp. (OSM 641.1-16). Greene County: 

 Huffman Dam, Bath Twp. (WED 440). Hardin County: 3 mi. E of Mt. Victory 

 (OSM 620, 621.1-3; SL 486-7). Huron County: Willard (CMNH 140-5). 

 Lucas County: Oak Openings, west of Toledo (SL 993). Montgomery County: 

 Riverside (DPLM 631.44). Paulding County: Near Charloe (OSM 492). Por- 

 tage County: Atwater Twp. (Dexter, 1944). Trumbull County: North Bristol 

 (NU 7). Wyandot County: Sec. 9. Pitt Twp. (OSM 542). 



Among the above specimens, CMNH 54, 141, 143, 144; OSM 621.1-3; 

 SL 486-7; and TMS 2466 are either m.elanistic or so dark and with so little 

 evidence of pattern that they may have been melanistic in life. The mother of 

 OSM 620 (a juvenile bom in captivity) Ls said to have befen black also. Sev- 

 eral of these snakes, it will be noted, are from 3 miles east of Mt. Victory. 

 Many more rattlers have been collected there during the past decade (Rausch 

 and Camin, for example, caught thirteen in a single afternoon), but it is still 

 possible to state that all adults taken in that locality have been black and all 

 juveniles spotted (see page 113). 



In at least two areas where the massasauga formerly was abundant it inav 

 soon disappear altogether. The New Haven Marsh (see page 115), accord-
