Later they resumed." The embrace was a normal axillary amplexation as it 

 was with the mated pair of June 4, 192 1, the two pairs of July 3, 192 1, and 

 the pair of July 7, 1921.

Habitat. Under voice we have noted this species in the bushes in the ver- 

 dant edges of Billy's Lake and in a cypress pond (C.A.G.) with its mats of 

 sphagnum, Hydrocotyle, Iris, Pontederia, Saururus, Castalia, Nymphoides, 

 etc. On May 19, 192 1, we made these comparative notes on habitat from 

 one cypress pond: "Rana clamata along outer edges in Decodon, some Pon- 

 tederia and entirely on east side of Long Pond. Rana grylio in middle. Acris 

 gryllus widespread. Hyla jemoralis mainly on either northern or southern 

 end. Hyla cinerea out in the middle and around edges also but Hyla jemoralis 

 as yet around edges." They also breed commonly on the prairies, sometimes 

 in the cypress bays and at times in transient pools or inundated cultivated 

 fields of the islands or mainland. 



Period. In 1915, at Jacksonville, Florida, Deckert (p. 4) reported that 

 "This species seems to have no special breeding season, and is never heard in 

 the early spring, when the majority of the other frogs and toads congregate 

 at the shallow bayous." Pope (1919, p. 96) of Houston, wrote 'T could get 

 no light on its breeding habits." 



From the evidence of mated pairs in 192 1 we might call May 10- July 7 

 the maximum period. In 192 1 we recorded eggs May 18, May 23, June 4, 

 July 3 or from May 18- July 3. 



In 1923 Wright (1923, p. 34) held that "From May 15th to June ist five 

 more (species) start (ovulation). . . . Hylacinerea . . ." In 1924 Wright and 

 Wright (1924, p. 378) give the "Season, May 19 to August 21" as the period 

 of ovulation. Another note represents breeding as beginning May 10 and still 

 another notation has the period from May 18- July 30. 



In 19 1 2 we evaluated our evidence as follows: "We suspected this species 

 must be breeding during the period of the greatest choruses which we re- 

 corded May 30- June 4. Of the 12 adults taken between May 30- July 15, 

 19 1 2, only two were females (taken respectively June 3 and June 6). Only 

 the first of these two was gravid, the other was spent. Of the ten adults 

 secured after July 15, four proved ripe females. Then, the remains of an- 

 other frog taken June 15, 19 12, from the stomach of a black-snake proved 

 to be a ripe female. Thus we have outhned a period of ripe females from 

 June 3- July 1 5 or later. The species may breed from the last of May through 

 June and July." 



A summary of our material on the basis of spent and unspent females for 

 years not of 19 12 is as follows: On April 28, 192 1, the only two females caught 

 respectively 55 mm. and 57 mm. are spent. On May 15, 192 1, we took three 

 females, two 55 mm. and 56 mm. spent, and one 57 mm., gravid. In June, 

 191 1, at Spring Creek, Decatur Co., Ga., Professor J. C. Bradley took two 

 females 44 and 59 mm. respectively, each gravid. On June 5, 192 1, we se- 

 cured a ripe female 59 mm. long. The day before another unspent female 57
