444 Frogs of the Okefinokee Sivmnp 



R. sphenocephala, R. aesopus, R. septeritrionalis, R. syluatica, and other be- 

 neath-the-surface layers. The process probably requires a few minutes. The 

 female may start slowly but once the process begins it doubtless is over in 

 10-30 minutes. 



EGGS 



Attachment. The masses found July 28 were attached as follows: The 

 first mass was "found in a clear area attached to a Xyris blade and pine needles 

 and beneath the water, ..." Six more were found the morning of July 22, 

 1922. "They were attached to pine needles, upright sticks, Xyris or Erio- 

 caulon stems." In the afternoon we "found a mass much farther west than 

 the original area of 5 masses. It looked blue above and when turned over 

 showed a creamy white impression. The mass like those of Rana spheno- 

 cephala and Rana pipiens, looked white below. The mass was 2f x if inches. 

 As in Rana sphenocephala and Rana pipiens it seems to lay in groups as in 

 case of 5 masses yet this last fresh mass was considerably apart from others 

 in water 6-8 inches deep. If most of the eggs are laid beneath the algae on 

 the surface I am lucky to find these few masses. The species may, however, 

 choose clear water areas with little algae for ovulation." Other observations on 

 attachment are "Attached to fresh floating pine needles (Pinus carihaea). . . . 

 Attached to rosettes of Eriocaulon |-f inches below the surface." 



Egg mass. The masses were more like the eggs of Rana sphenocephala 

 than those of Rana grylio. The first mass was "not globular but somewhat 

 elongate. The top of the mass was at or just beneath the surface of the water. 

 No rain had intervened since last night. The mass may have been 1.5 x 3 to 4 

 inches." "About eight or ten feet farther into the area were four more masses 

 two not far apart and two very close together. Isolated was another mass. 

 These five with original mass found makes six. These were all beneath the 

 surface. Very small masses for frogs. The temperature when we found them 

 was 72°." 



Other data is as follows: "Sometimes in looking for Cope's frogs' eggs we 

 mistake the bladders of Utricularia purpurea for a mass." "... A mass 

 2x2x2 inches." "Another mass in water 4 inches deep, i inch below surface, 

 I inch thick, plinthlike, 2I x 2I inches, a perfect duplication of R. spheno- 

 cephala masses. This last mass 15 feet from two others which are 4 feet apart." 

 "Another mass, water 3 inches deep. Beneath surface attached to Eriocaulon. 

 Very much like southern meadow frog's mass." "One mass attached to Erio- 

 caulon leaves, if x 4 x i inches, a fine plinth but elongate, strap-shaped." 

 "Another mass attached to Rhexia mariana." 



One has to be careful. "Right near one of the Rana virgatipes mass was a 

 very large mass as big as some Rana sphenocephala masses. Is it R. spheno- 

 cephala? We took it in to camp. Later in the day we proved it to be Rana 

 sphenocephala. The eggs were different and had inner envelopes." 



Egg description. Our first field description of the egg is "The eggs are 

 large, far apart like Rana sylvatica eggs and seem to have no inner envelope." 

 At camp we made the following hasty notes: Vitellus 1.5, 1.5, 1.7, 1.6, 1.6, 1.4,
