26o Frogs of the Okefinokee Swamp 



MATING 



Male (From, life, April 26, 1921). In dark olive green male there are twenty 

 orange spots scattered over the back, lighter in green of sides below lateral 

 stripe; stripe (cream colored) extends almost to hind legs. Obscure on snout 

 ahead of eye. Cream colored or white stripe on back of forearm. Iris bronzy. 

 Pupils horizontal. 



Same on back of lower leg and along hind end of foot. Throat from angle 

 to mouth to slightly back of chin green. Chin proper yellowish cream. Back 

 of these two areas, yellowish cream and green, is the wrinkled pink area of 

 the throat proper. 



One light colored male with stripe straw-colored, only an inch behind in- 

 sertion of arm area black above and below the stripe. (Non Ridgway.) 



{From life, May 18, 1921). Back may be apple green, dark green olive, 

 greenish oUve, deep slaty olive to almost black, the stripe on side light dull 

 green yellow or clear dull yellow. In one male stripe not beyond tympanum 

 and suggestive of H. evittata. The vent, forearm stripe, foot stripe and heel 

 are white. One dark male had the foot stripe fainter. Iris russet vinaceous. 



Female {From life, April 26, 1921). With no pink chin, green extends in 

 on sides of throat for slight distance. Straw colored stripe to insertion of hind 

 legs prominent, also stripe under eye and around stripe. Under parts from 

 groin to chin the same cream color. (Non Ridgway). 



{From life, May 18, 1921.) Back may be from apple green to deep slaty 

 olive. Stripe pale chalcedony yellow. 



Structural differences. In the pair of May lo, 192 1, the female was much 

 longer. On June 4, 192 1, the mated pair captured the day before was colored 

 at 11:00 a. m. as follows: Female, yellow green; male deep slaty olive. An- 

 other female in the jar was also deep slaty olive. 



In 191 2 we analyzed the differences thus: In the series of 23 adults, with- 

 out exception the six females are the largest being 56, 57, 58.5, 59, 59, 60 mm., 

 average 58 mm. ; while the 1 5 males range from 46-55 mm., average 5 1 mm. Of 

 course, the females can be told because of the absence of the vocal sac which 

 in the males is not especially colored. In one or two of the females the throat 

 was quite greenish across the whole width. The breast fold is not so promi- 

 nent and the throat region not wrinkled area (in spirits). A firm and full 

 appearance in the inguinal region reveals the ripe females at once though the 

 waist is almost as in the males, — slender even when the eggs are ripe. In the 

 male enlarged thumbs or nuptial excrescences seem to be absent. 



A survey of our 192 1 and 1922 material with comparisons with our 19 12 

 Okefinokee specimens and other material from other parts of the range of this 

 species reveals two gravid females of 41 mm., two females at 44 mm. and one 

 at 45 mm. One would expect the male external characters to appear slightly 

 smaller. One 35 mm. specimen has a slightly wrinkled throat. One specimen 

 of 37 mm. has the throat wrinkled and is a male. Of three 38 mm. specimens 

 one is doubtfully male externally; another has the throat wrinkled but not 

 prominently and is a distinct male. Two specimens 39 and 42 mm. appear to 

 be males. From 44 mm. onward we have many males. The evidence if sum-
