210 THE AMERICAN MIDLAND NATURALIST 



south of th? glacial boundary. This section of the state, from Ross and Hock- 

 ing counties southward to the Ohio River, possesses a particularly rich reptilian 

 fauna. Many species here reach their northernmost limit (at leart in Ohio), 

 among them being Lygosoma latcrale. Lam pro pelt ts g. nigra, Haldea v. 

 valeriae, etc. The timber rattlesnake has survived here in some numb-rs, and 

 Storeria o. occipitomacnlata is not rare, although it is found elsewhere in Ohio 

 only in distant parts of the state. A wide variety of habitats and extensive 

 forested areas no doubt contribute to the richness of the region. 



Einn.eces jasciatus may have crossed the glacial bounc'ary and entered south 

 central Ohio by making use of "filled" valleys in much the same manner as is 

 postulated for Natrix kirtlandii, Storeria dekayi, and Thamnoph.s sauritus. 

 (See the discussions concerning these species on the pages that follow.) This 

 skink is partial to moist habitats such as are found in filled va'leys, and 

 from the field notes available, it appears to avoid the well-drained hil's that 

 characterize much of the region. 



The general range map (page 29) needs some slight alterations. Florida 

 should be eliminated completely, and the c'ark area should be extended north- 

 ward to Lake George in New York. Goin (1940) poiats out tha; all ex'stirg 

 Florida records for this lizard are open to question; Hamilton (1947) reports 

 the species from near Hague, New York. 



My data now include detailed scale counts for ninety-three Ohio specimens 

 of jasciatus. These may be summarized as follows: 



Scale Rows — 26 (in 2 specimens); 27 (in '^); 28 (in 32); 29 (in 20); 

 and 30 (in 33); one additional lizard from Toledo, Lucas County, has 32 

 scale rov/s and another from Clermont County has 33. 



SuPRALABiALS — A count of 4 supralabials (preceding the subocular labicl) 

 occurs 156 times (allowing two for each lizard, one left and one right) and a 

 count of 5 occurs 30 times; in twelve specimens there are 4 labials on one side 

 of the head and 5 on the other; in nine specimens the count is 5 on both s'des. 

 The last nine skinks are from widely scattered localities — Butler, Franklin, 

 Hardin, Lucas, Union, and Vinton counties. 



PoSTLABiALS — There are two postlabial scales in 87 of the 93 specimens 

 and another has one large postlabial (on one side of the head) which is appar- 

 ently the result of fusion of the two smaller scales. Only five lizards may be 

 said to have aberrant counts; three of these have two pcstlabials on one side of 

 the head and one on the other; ano'^her specimen has two on one side and 

 three on the other. Only a single specimen (from Fort Ancient, Warren 

 County) has a single postlabial on both sides of the head. 



Scale rows in excess of 30, counts of 5 supralabials, and a single enlarged 

 postlabial scale are all characteristics that are usually associated with cpecim.ens 

 of Eumeces laticeps. A glance at the above figures will show, of course, that 

 there is some overlapping and that a few individuals of jasciatus bear counts 

 that might be diagnostic of laticeps. None of them, however, have complete 

 combinations of the characters of laticeps. For example, the ja';ciatiis from 

 Lucas County with 32 scale rows has only four supralabia's and it has two
