Hyla andersonii 241 



soon after they are laid. To continue with the description. "The egg is 

 surrounded by the vitelhne membrane and by the two gelatinous membranes 

 of the usual type. The gelatinous capsules vary enormously according to 

 their age and treatment. The following measurements are taken from a 

 series preserved in formalin. They agree well in size with some living speci- 

 mens. Diameter of Ovum — 1.2-1.4 mm. Diameter of Inner Capsule — 

 1,9-2.0 mm. Diameter of Outer Capsule — 3.5-4.0 mm. The vitelline mem- 

 brane may be best demonstrated after maturation when the animal pole is 

 slightly flattened leaving a space between membrane and ovum. 



"In nature, H. andersonii was estimated to lay eight hundred to one 

 thousand eggs. None of our laboratory animals laid more than eight hun- 

 dred eggs." 



HATCHING PERIOD 



Noble and Noble (1923, p. 441) had eggs hatch in laboratory in four days 

 and beHeved it would take longer in nature. In South Carolina or North 

 Carolina it might even happen in less than four days. In New Jersey it 

 might be longer or shorter. 



MATUEE TADPOLE 



Color description from life {May 23, 1924)- General coloration of body 

 olive, brownish olive, or dark olive. Back with scattered black spots. Gill 

 region with a sheen of ochraceous salmon or vinaceous tawny or vinaceous 

 salmon. Interspersed with this color is some black. The mental region is 

 clear of color. Below eye blotched with black, bronze (or one of three gill 

 region colors) and green yellow. Over the belly in younger specimens is a 

 full block of ochraceous salmon or vinaceous cinnamon. In older specimens 

 green-yellow or citron yellow or sometimes seafoam yellow across the belly 

 or on the gill region. 



Tail. Starting from the base of the tail there is a longitudinal irregular 

 blackish band along the musculature of the tail one-half of an inch or more 

 from the tip of the tail. This band is more or less interrupted, not a clearly 

 defined band as in Hylafemoralis or in Pseudacris ocularis or other Pseudacris 

 species. Below the band is a clear area of warm buff or cream color or car- 

 tridge buff or seafoam yellow. In some specimens there is a similarly colored 

 area 1/8-1/4 inch long above the dark band. The very lower edge of the 

 musculature is with a fine purplish line. Just above this edge are a few scat- 

 tered collections of black dots. Upper and lower crests heavily clouded with 

 blackish dots which in places assemble in clusters. In younger tadpoles quite 

 a prominent irregular margin of blackish on the crests and the musculature 

 band of black more regular and not so interrupted. 



Eye with pupil rim prominent ochraceous salmon or vinaceous tawny 

 or vinaceous cinnamon. Rest of pupil spotted with this color and black. 

 All in all it is a prominently colored eye. 



General appearance. Tadpole (35 mm.) full and deep-bodied. Tail 

 medium to fairly long, tail tip acuminate or sharply acute. The dorsal and 

 ventral crests about equal. The dorsal crest is less than the depth of the
