Hyla andersonii 247 



group with heavily spotted and somewhat scarlet suffused tails ( H. arenicolor, 

 H. femoralis, H. versicolor). Neither do they superficially fall into the 

 greenish tadpoles of H. gratiosa, Hyla cinerea group. Examinations of their 

 mouth parts apparently put them near this group (short third lower labial 

 tooth row and other characters). 



This topic could be expanded at will. The value of certain criteria in 

 determining its possible relationship to Hyla arhorea, or to Hyla pulchrilineata 

 are not for me to discuss. If we let license run riot we might call it a northern 

 representative of H. gratiosa, or an offshoot from Hyla squirella as a radiation 

 center or a Hyla cinerea derivative just as Hyla c. evittata apparently is. The 

 writer is still searching for slow coming material before he indulges in that 

 joyous privilege of final pronouncements on questions of relationships. 



Though not exactly pertinent to the topic of affinities possibly the follow- 

 notes from hfe may be interesting. In camp 1922 at Chesser Island we had 

 a male Hyla andersonii (from North CaroHna) and males of Hyla cinerea, 

 Hyla femoralis, Hyla versicolor d^nd Hyla squirella. Our rough journal notes 

 reveal the following notes made at one sitting under similar conditions with 

 fresh material. 



Back. Hyla andersonii, cress green; Hyla cinerea, rear greenish- 

 yellow; head viridine; Hyla femoralis, brownish drab. Hyla versicolor, rear 

 pale smoke gray; rest grayish olive to vetiver green; Hyla squirella, buffy 

 brown or isabella color or old gold ; rear, yellowish citrine or apple green. 



Degree of white on venter. Hyla andersonii, whitish on venter; Hyla 

 cinerea; Hyla versicolor; Hyla femoralis; Hyla squirella, least whitish on 

 venter. 



Degree of orange. Hyla squirella, most orange below; throat, under side 

 of fore feet, fore limbs, hind limbs and hind feet fore and aft. Hyla andersonii, 

 front and rear of hind limbs when revealed ; under side of foot ; Hyla versicolor, 

 groin; front and rear of femur shows it slightly. 



Green on throat of males: Hyla andersonii, Hyla cinerea, (Hyla gratiosa). 



Iris. Somewhat of same color as back: Hyla cinerea, Hyla versicolor, 

 Hyla squirella, Hyla femoralis. Somewhat like vitta : Hyla andersonii. 



Vitta. Hyla cinerea, Hyla versicolor, no vitta nor stripe through the eye; 

 Hyla femoralis, Hyla squirella, line in front of eye obscure or absent; Hyla 

 andersonii, vitta prominent.
