gray or pallid purplish gray. In another specimen two lower bars united. 

 Rest of eye black with a little dotting (irregular) of the two combinations 

 (upper and lower bars) of colors. 



Structural differences. Some of the differences in males and females appear 

 summarized below: 



1 . In describing the coloration we noted that "the males have yellows 

 on the folds, tubercles, iris, axilla and groin somewhat wherein the 

 females have little or no yellow. Possibly LeConte's description of 

 R. capita is from a male. This may need more rechecking. 



2 . The male has the thumb enlarged and the female not, but the thumb 

 is not as enlarged as in some species. 



3 . The males average smaller. The adult males externally are first re- 

 vealed at 68 mm. and reach to loi mm., while the females range from 

 77-181 mm. 



4 . The antebrachium is very much wider in the male than the female and 

 this widening may even reach up to the brachium. 



5 . Under Voice attention is called to the sacs which in Rana aesopus as 

 well as R. areolata may be immense and in alcohol may appear as ex- 

 tending far beyond shoulders. In life sometimes they look to reach 

 even farther backward. 



6 . Some notes on alcoholic specimens are : 



(a) 68 mm. cf. Thumb enlarged. 



(b) 68 mm. cf. Thumb enlarged. Sac partially developed. 

 Very spotted on throat and pectoral region. 



(c) 81 mm. cf . Thumb somewhat enlarged and slightly colored. 

 Sacs fairly developed. 



(d) 85 mm. cf. Thumb enlarged. Sacs show. 



(e) 87 mm. cf. Thumb somewhat enlarged and darkened. 

 Beautiful sacs half way to groin. 



(f) 90 mm. cf . Thumb well enlarged, dark sacs well developed. 

 Amplexation. It is presumably axillary but we have recorded no pairs 



of this species. 



OVULATION 



Habitat. We found it breeding in a cypress pond with no open center. 

 We found tadpoles in an open centered cypress pond, in an open centered 

 pond with bay tree circle, in an open pond with St. John's wort {Hypericum) 

 circle, in an open pond in pine woods or an old field, no special circle of vege- 

 tation, in an open pine forest pond at the edge of a wet savanna. 



Period. We have long suspected that this form bred in the first half of 

 the year. In 192 1 we were within the swamp and missed this form until 

 July. In 1922 we arrived June 11. Deckert (191 4, No. 5, p. 3) writes: 'Tts 

 call can be heard from late February to the end of May. These frogs croak 

 only at night, and are then easily caught by the Hght of a lantern. The writer 

 has also collected this species during the breeding season in February near 

 Jacksonville, Fla., in 191 2 (Deckert, 1920, p. 26). It would seem then that it
