and legs. There are irregular dark borders on the upper and lower jaws 

 ending in a dark spot at the shoulder. The throat of the male is dull 

 greenish tan, that of the female white. Dr. Remington Kellogg in his 

 Mexican series found a dark spot on each eyelid, but none of our frogs 

 from Winslow, Arizona, had it. 



Structure: Skin smooth above, granular below; a fold of skin 

 across chest; a fold across the base of the throat in the female; fingers 

 and toes with well developed disks; the fourth toe very long; fingers 

 slightly webbed at the base; toes 1/3-1/2 webbed; tympanum half 

 the diameter of the eye; tibia half the length of the body; a tarsal fold 

 present; inner metatarsal tubercle present, but outer metatarsal 

 tubercle present, inconspicuous or absent. 



Voice: The call is a low pitched, harsh, metallic clack. There is no 

 trill in the call which consists of two to ten or twelve or more notes 

 given in succession. These may be speeded up toward the end of the 

 call. The vocal vesicle is very large, single and transparent with less 

 yellow or green in it than is found in most tree toads. 



Breeding: In United States, records indicate breeding from June 

 to August. Two ripe females were taken at Santa Fe, New Mexico, 

 June 18, 1874, by H. W. Henshaw. The deep olive and dull citrine 

 tadpole is medium sized, 1 11/16 inches (43 mm.), and has tooth 

 ridges 2/3. It transforms from July onward at 1/2-9/ 16 inch (13- 

 13.5 mm.). 



Notes: "While at Mormon Lake, Arizona, on August 16 and 17, 

 1931, an interesting amphibian was found. A heavy rain came in the 

 afternoon of August 16. After dark, frogs were heard calling near the 

 lake shore, an interrupted chirp of a series of four to six notes often 

 repeated. The maker of the call was found to be a Hyla, dull green 

 above with brown spotting. Two males were collected on the first 

 evening. The next day, while walking along the trail to the fire look- 

 out tower, a female was taken. Another male was found near the top 

 of Mormon Mountain. The species, which proved to be Hyla eximia, 

 typically of Mexico, was found only on the ground, usually near the 

 lake. Their occurrence so far from their reputed range seems worthy 

 of note. Dr. Dunn has examined the specimens and confirmed their 

 identification." (F. Willis King, 1932, p. 99). 



On June 10 or 12, 1933, as Mr. W. L. Chapel, Jr., was starting for 

 Arizona, we showed him illustrations of Hyla eximia. On July 6, he 

 writes from Winslow, Arizona, somewhat as follows: "At present I am 

 at Los Burros CCC camp near McNary. The last few days, we have 

 had considerable rain. Toads are quite numerous about camp. Today 

 we were working at Los Burros which is about six miles from Winslow. 

 In a swampy place, I heard quite a chorus. I found endless numbers of 

 green frogs. No other species could I find. I am sending these, eight 

 of them . . ." On arrival, they proved to be four males and four 

 females of Hyla eximia.
