Rana virgatipes 445 



1.5, 1.8, 1.6, 1.7, 1.8, 2.5 (embryo elongated) mm. ; envelope 5, 5, 5, 5.3, 4.9 x 5, 

 5, 6 X 6. 9, 5, 5.8, 5 X 5.8, 5 X 5.8, 6 mm. Occasionally jelly envelope flattened 

 spheroid-like. Jelly firm — often a flat surface where stuck to adjoining eggs. 

 Envelope single." "Envelope 5.2, 5.5, 5.2-5.8 mm.; vitellus 1.6, 1.5, 1.4 mm." 

 "Several fresh eggs have the envelope 3.8-4.2 mm." 



The egg complement is rather small. One mass has 349 eggs. Another 

 had 474. "Some may reach 500 or 600 eggs but 474 was larger than some 

 complements. One mass looked to have little more than 200." 



"The eggs are black above and a creamy white (not white as in Rana 

 sphenocephala and Rana pipiens) i.e. more creamy in fresh eggs than these two 

 species. Soon the black encroaches on the light vegetative pole. The eggs 

 look far apart as do Rana sylvatica eggs and being without an inner envelope 

 the parallel goes farther in that the outer envelope of Rana sylvatica gets to be 

 as much as 5.8 mm. as does the envelope in this species. Very fresh eggs 

 sometimes look to have sulphur yellow vegetative poles and black animal 

 poles." Comparisons with Ridgway colors made the colors "primrose yellow, 

 naphthalene yellow or light chalcedony yellow. Not so yellow as in Rana 

 palustris eggs." 



The eggs and egg mass were identified presumptively. We neither saw 

 the eggs laid in the field nor did we capture mated pairs. They are Rana 

 virgatipes for these reasons : 



1. The female taken the night of July 21 was near where a male Rana 

 virgatipes was croaking. We brought her into camp. On July 22 in the after- 

 noon Mrs. Wright when photographing the female accidentally pressed some 

 eggs out. Later July 23 (morning) the female though unattended by a male 

 had laid eggs in the jar. These checked with the eggs of the masses of the 

 field. This was in the nature of direct identification. No end of male Cope's 

 frog were croaking in the area where the female was taken. This is presump- 

 tive evidence. 



2. They were not films as in Rana grylio and Rana clamitans. On July 23, 

 1922 we held there were only four anurans in Okefinokee swamp whose eggs 

 were not surely known : Scaphiopus holbrookU, Pseudacris nigrita, Rana aesopus, 

 and Rana virgatipes. They could not be the first two, no gopher frogs were 

 calling that night nor of the first two species. The presumption was that they 

 were R. virgatipes. The eggs were of the type of Rana sphenocephala or Rana 

 palustris but without the inner envelope. In this respect they were Hke R. 

 catesheiana eggs (but these are in films). No R. sphenocephala were calling 

 when we were at area the night of July 22. A mass of this species, however, 

 was later found. 



3. On the morning of July 25, 1922, at the boat landing (strand or sphag- 

 num run) "Ridley and Mattie Chesser found a Cope's frog in the boat. It is 

 a female, gravid. Must have leaped into the boat and couldn't get out. This 

 female is smafler than any of the four males captured. When Anna (Mrs. 

 Wright) was cleaning her off for photography the female voided a few eggs. 

 Later I did the same and secured more eggs. These vitelli were somewhat less
