320 Frogs of the Okefinokee Swamp 



In 1922 field examinations of the eggs gave the following summation: 

 'Mtellus .8-1.0 mm.; inner envelope 1.2 -1.6 mm., outer envelope 1.4- 1.8 mm. 

 Eggs brown above, cream below." 



Laboratory examinations gave .9 mm. as average vitellus, range .8-1 .0 mm. 

 inner envelope, average 1.4, range 1.4-1.6 mm.; outer envelope average 1.6 

 mm., range 1.4-2.0 mm. 



Dangers. On August 11, 1922, at Camp Pinckney "we found countless 

 males in temporary pools 1-3 inches deep. Must be that they lay single eggs. 

 Must lay in shallow pools. No end of the tadpoles must be lost from drying 

 of breeding places." 



HATCHING PERIOD 



The eggs laid July 3-4 hatched in laboratory in about two days. In fact 

 some of the eggs (No. 998) laid July 4, i :oo-7 :oo a. m. hatched July 5 at 

 12:00 noon or 36-43 hours after ovulation or i 1/2 or i 3/4 days required for 

 liatching. This was in a period when maxima averaged near 88-90° and 

 minima close to 7o°F. 



TADPOLE 



Color description from life {June 23, 1922). General color of body citrine 

 drab. In general it has a greenish cast hke tadpoles of Hyla cinerea and H. 

 gratiosa. Developing ventral flap between hind legs ecru-olive; throat from 

 line of eye to eye to mouth same color. Area behind gill area ocher red. 

 Belly pigmented testaceous and chalcedony yellow. These make a solid 

 iridescence which on the sides and across the middle venter becomes replaced 

 with black. 



Tail. Muscular part of tail dark olive buff. Muscular part without 

 prominent clusters of blackish spots. The dots are uniformly scattered over 

 the muscular part but slightly thicker near the tip. The tail reminds one 

 more of a Ranid tadpole tail in coloration. 



Iris more or less black with a rim of testaceous or light coral red and 

 chalcedony yellow spots amongst the black. 



General appearance. Tadpole small (32 mm.) full and fairly deep bodied. 

 Tail long, tail tip acuminate a fiagellum present. Dorsal and ventral crests 

 well developed and tail in general deep. Dorsal crest not so deep as the tail 

 musculature. Dorsal crest extends on to the body about to the vertical of 

 the spiracle. Spiracle sinistral directed upwards and backwards, well below 

 the lateral axis, the spiracular opening prominent elliptical lateral axis, is in 

 dorsal aspect on the lateral outline and in consequence is visible from the 

 venter. Anus dextral, opening at the level of the edge of the ventral crest. 

 Muciferous crypts indistinct. 



Mouth parts: Teeth 2/3. Upper labium fringed with a continuous row of 

 labial teeth; the papillae extend above and inwards beyond the end of the 

 upper fringe for about 1/2-3/10 of upper fringe. The end of the second upper 

 labial row is usually even with the end of the upper fringe. The horny beak 

 is contained about 1.8-2.0 times in the upper fringe. The median space 

 between the lateral second upper labial rows of teeth short, 3.25-5 in the length
