a large dorsal spot with two forks. Various irregular lateral spots of 

 black form a reticulation on a yellow or olivine side area. There are 

 transverse bars on the legs, a light greenish spot under the eye, a 

 light line above the dark edged upper jaw, and a dark line from eye 

 to shoulder ending in a prominent black patch. The breast and throat 

 may be spotted with dark. The posterior surface of thighs has spots. 

 The sides are yellow posteriorly. In the female, the under parts of 

 the throat and upper breast are white, the lower breast and belly 

 white suffused with pale green. In the male, under parts are cream 

 buff with lateral throat sacs, a pale brownish drab. The rear of the 

 femur is yellow and russet, the underside of the hind legs is onion 

 skin pink with yellow crowned tubercles. 



Structure: Skin, smooth above, set with fine tubercles; under 

 parts granular; tympanum nearly as large as eye; fold of skin from 

 eye to shoulder; prominent fold across breast; disks large, fingers 

 slightly webbed, toes webbed; a distinct tarsal fold. 



Voice: The vocal sac is better developed on either side of throat 

 than in its middle. The note is a burred keck, repeated 5-12 times, 

 followed by a chuckle. These repeated kecks may last 2 or 3 seconds. 



Breeding: The only record on transformation is of one specimen 

 transformed, or 'just past, from Panama, 7/8 inch (21 mm.) in length, 

 which was caught February 19, 191 1. They were in full chorus in 

 Brownsville, Texas, June 19, 1930. In Southern Vera Cruz, A. G. 

 Ruthven found this species common. He observed them breeding, on 

 July 17. In 1908, near Cordoba, Vera Cruz, Dr. H. Gadow found a 

 spawning congress of 45,000 frogs. His account is very vivid. 



Notes: June 18, 1930. Brownsville, Tex. I went out the Military 

 Road two or three miles where the road comes opposite a resaca 

 which is 1/2 to 3/4 mile from the road. From the road, I heard a 

 chorus new to me. My guess was H. baudinii. Pell mell I started, 

 plowing through tomato, corn, and cane fields. ... On little bushes 

 or amongst tomato vines I heard these new frogs. . . . The first 

 frog I never could locate, though I was almost on it in a tangle of 

 grass and vines. Finally I located one in a bush where the water was 

 waist deep. It was on a branch one foot above the water. This one 

 was yellow-green. Then followed another. It was brown in color and 

 on the ground where the water was shallow. I tried for several more. 

 Whenever I approached, they stopped. In a pond beside the river in 

 Brownsville I heard another //. baudinii. It was deep green on the 

 back. None except the brown one had markings on the back revealed. 

 The last one was found on the surface of the water amongst a clump 

 of weeds. 



August 22, 1930. Went over to Mrs. Olive Wiley's museum in the 

 Minneapolis Public Library. . . . She had a beautiful Hyla baudinii 

 from Central America. It came on a bunch of bananas to a local 

 merchant.
