1 92 Frogs of the Okefinokee Sivamp 



as in A. gryllus having a considerable resemblance to a toad. Varies ex- 

 tremely in color and in other marks. The only unvarying marks which I have 

 been able to disover are the warts on the back, the dusky line from the axilla 

 on the side (which sometimes almost vanishes), the darker angular spot above 

 the anus (which at times is scarcely perceptible) and the white granules on 

 the hinder and under parts of the thighs. . . ." 



In 1858 (pp. 70, 71) Gunther places the genus "Acris Disk small. Toes 

 broadly webbed; fingers free; tongue heart-shaped. North America." in the 

 Polypedatidae. Interestingly enough he places Acris picker ingri in this 

 genus and holds "This genus might belong to the family of Hylidae. Bibron 

 and also Baird describe the diapophyses of the sacral diapophyses of the 

 sacral vertebra as not dilated ; but I ask naturalists having the opportunity 

 of examining fresh specimens to direct their attention to this subject. The 

 relation to Pseudacris nigrita is very great, which species also exhibits only 

 slightly dilated processes." 



In 1882 (pp. 336, 337) G. L. Boulenger gives three forms. "Acris gryllus. — 

 United States: the typical form confined to the Austral riparian region, the 

 var crepitans to the Eastern and Central regions." 



"Var crepitans — Differs by a stouter habit, the head being shorter, and the 

 tibio-tarsal articulation reaching hardly the tip of the snout. According to 

 Mr. Cope (Check-list N. Amer. Rept.) this form should not be specifically 

 separated from the preceding, but both are considered subspecies." 



Var. hufonia. Resembles the preceding, but the head and back are covered 

 with very large warts. Markings indistinct. Perhaps a species. 9 New 

 Orleans. 



Cope (1889, pp. 324, 325) holds that "It is quite possible that it may 

 become necessary at some future time to unite this genus with Hyla." . . . 

 The northern and southern sections of this area produce forms which offer 

 considerable differences, but which must be termed subspecies, on account of 

 the existence in some localities of intermediate individuals. I have seen 

 such from lUinois, Pennsylvania, Missouri, and elsewhere. 



"These subspecies are as follows: Hinder foot less tarsus less than half of 

 the length of the head and body; dermal tubercles larger; posterior femoral 

 stripe less distinct — Acris g. crepitans. Hinder foot less tarsus longer than 

 half head and body; dermal tubercles smaller; femoral stripe very distinct. — 

 Acris g. gryllus. 



"These subspecies are respectively of northern and southern distribution, 

 the A. g. gryllus ranging from North Carolina to Florida and Louisiana." 



"Specimens from the lower Mississippi are frequently of obscure colors, 

 of rather larger size, and with large tubercles. I have not been able to dis- 

 tinguish them as forming a constant subspeeies. Mr. Boulenger . . . refers 

 such a specimen to a *var. bufonia.' " 



"As regards the transition of this subspecies and the A. g. crepitans, a 

 number of specimens display intermediate proportions. Thus in some the 

 posterior foot, minus the tarsus, is exactly half the length of the head and
