SALIliNTIAN RANGE EXTENSIONS 



7. Hyhi versicolor chrysoscclis (Cope). 



Le Flore ( 1), McCurtain (1). 



On a humid afternoon in late May a single treetoad was calling from the 

 woods near the bridge over Little River on Highway 70 between Broken Bow 

 and Idabel, McCurtain County. The call was recognized as an amphibian 

 voice never before heard and every effort was made (without success) to 

 secure the specimen. The call suggested that of H. v. versicolor in general 

 type, in length, and in interval but differed in being much hoarser in tone. 

 Rainfall brought out a large number of breeding individuals the following 

 evening and a thorough search of the area from Idabel to the river was made. 

 The hoarse-voiced Hyla was heard all along the river valley but not in the 

 uplands above the river. Here, in contrast, the calls of typical H. v. versicolor 

 were abundant. On the upper slopes the calls appeared to be intermediate in 

 tone. At a jxiol almost on the bank of the river, several specimens of the 

 hoarse-voiced form were stalked individually, by following their calls, and 

 captured. Since they conform to th^ description of H. v. chrysoscelis (Cope) 

 as given by Wright and Wright (1942), since they occupy a habitat given 

 there as characteristic of this form, since this subspecies might be expected in 

 this geographic region, and since the calls differ from those of H. v. versicolor, 

 I conclude that the specimens represent chrysoscelis which have migrated up 

 the valley of Little River from Arkansas where they are known. This, so far 

 as I am aware, constitutes a new state record for the presence of this subspecies. 



Some days later, H. v. chrysoscelis was heard again, this time in the 

 valley between Rich Mountain and Black Fork Mountain near Page, Le Flore 

 County. Before dark calls of H. v. versicolor were heard at intervals along 

 Highway 270 between Heavener and the head of this valley about three miles 

 northwest of Page; but only on approach to the valley itself were the calls 

 of H. V. chrysoscelis heard. Here both forms were together at dusk moving 

 into a roadside pool, calling from the trees as they came. I went into the woods 

 and collected several by stalking calling males; taking care to keep them in 

 separate containers as caught. The males of chrysoscelis taken here were 

 smaller than the versicolor and were more difficult to secure because of their 

 tendency to stay in the deepest cover, particularly on trees surrounded by 

 vines of smilax. A mated pair was collected from an oak limb about six feet 

 from the ground, the first hylas I have found mated in trees. The female was 

 of normal size but the male was small. Later that evening, all down this valley 

 following the highway to Mena, Arkansas, calls of chrysoscelis were abundant 

 but no versicolor were heard all the way to Mena. One H. v. chrysoscelis was 

 heard within the city of Mena itself. 



All of this conforms to expectations as to the habitat of these two forms 

 (Wright and Wright, 1942), chrysoscelis being essentially a versicolor differ- 

 entiated in evolution in a valley habitat.
