Acris gryllus i8i 



HATCHING PERIOD 



The eggs laid May 15, 192 1, between 6:00 and 8:00 a. m. were approach- 

 ing hatching May 17 at 8:15 when preserved. Air minima of 61°, 64° and 65° 

 and maxima of 73°, 84° and 76° obtained these three days. The other set of 

 eggs laid May 15 hatched 12:00 (noon) May 19 or about four days later. 

 The air mimina from May 15-May 19 ranged from 63°-65° and maxima from 

 73°-84°, or an average for all of 72°F. 



MATURE TADPOLE 



Color description from life {July 5, 1921). General coloration dark olive 

 buff or old gold or ohve lake or sulphine yellow. Belly especially on sides 

 and on gill region light vinaceous fawn or shell pink or pale salmon color. 

 Belly with ivory yellow or cartridge buff clusters of spots. These clustered 

 spots almost cover the top of the body. The region back of the labial mouth- 

 parts has no light vinaceous fawn nor ivory yellow. The clusters of spots 

 become almost continuous and look a patch of French gray or lilac gray on 

 the throat region. 



Tail. Tip of tail (upper and lower crests) conspicuously black (at times 

 lost) . Clusters of ivory yellow or cartridge buff spots on upper crest and upper 

 part of musculature, less frequent on lower crest and lower musculature. 

 These spots somewhat amongst black of tail tip. Tail crests almost trans- 

 parent, certainly translucent almost clear of marks except under lens when 

 the course of the blood vessels are marked by the body color (dark olive 

 buff, etc.) 



Iris ivory yellow above and below, behind and in front of pupil light coral 

 red and black. Whole of iris more or less prettily marked with black inter- 

 spersed with the two lighter colors mentioned. 



General appearance. Tadpole medium (42.0 mm.) full and fairly deep 

 bodied. Tail very long, tail tip very acuminate, with black flagellum. Tail 

 proportionally the longest and most narrow (depth of tail in length of tail) 

 of any of the Hylids in the U. S. Dorsal and ventral crests rather narrow, 

 not equal to the tail musculature in depth. The dorsal crest extends on to 

 the body to the vertical of the spiracle or just ahead of it but nearer spiracle 

 than the eye. Spiracle sinistral, mainly directed backwards only slightly 

 upwards, and it stands out from body in life almost on the lateral axis. 

 Eye on lateral axis, eye hardly if visible at all from the venter (more like a 

 Ranid tadpole) suborbital region oblique and vertical as in Hylids in general. 

 Eye in dorsal aspect just inside the lateral outline. Anus dextral, opening 

 on a level with the lower edge of the lower crest. Muciferous crypts not 

 distinct. 



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

 of labial teeth ; the papillary border does not extend above or inwards beyond 

 the end of the labial fringe (unlike all our Hylidae of the U. S.). The end of 

 the second row of upper labial teeth extend beyond the end of the upper 

 fringe for 1/3 or sometimes about 1/2 of the length of the second upper 

 labial row (in H. crucifer 1/4-1/6 the length of either lateral row). The
