state that they are identical. 



Habitat: Moist meadows, irrigated cane fields; drains, gutters, in 

 towns; beneath stones and logs (Schmidt). Near streams and in 

 marshy places; in burrows in sand banks and fields (Stejneger). 



Size: Adults, i 2/5-2 inches (35-49 mm.). Dr. Stejneger records 

 one 5 5/8 inches (144 mm.). 



General appearance: This smooth-skinned medium-sized frog has 

 a dorsolateral fold and another below it on the side of the body. It 

 has no disks. A cream-colored or pale straw yellow labial stripe, a 

 dark vittal stripe from nostril to shoulder, and several rows of spots 

 on dorsum (light-margined or not), are some of the diagnostic color 

 characters. The general coloration of the dorsum may be olive, clay- 

 color, reddish brown, olive green, olive yellow, or other colors. Some 

 have a broad median stripe down the middle of the back. 



Structure: Tympanum 1/2-2/3 tne e y e » vomerine teeth curved, 

 slightly oblique, behind level of the nostrils; tongue slightly nicked 

 posteriorly; nostrils nearer tip of snout than eye; first finger longer 

 than second; second and fourth fingers equal; toes scarcely webbed; 

 two metatarsal tubercles; slight tarsal fold; interarticular tubercles 

 prominent; male with two vocal sacs, communicating with each other 

 and each with a separate slit; heels overlapping when at right angles 

 to the body. (Combined from Giinther and Schmidt). 



Voice: To Dr. Stejneger the voice is "fairly loud for its size. . . . 

 and can be expressed by the word 'pink' in frequent succession." 



To K. P. Schmidt "the chorus of this species is one of the most 

 insistent notes heard in Porto Rico, both by day and by night . . . it is 

 comparable in quality with that of the North American Acris. The 

 interval between notes is variable but usually very short and regular. 

 There is an occasional somewhat guttural trill. . . ." 



Breeding: From early in the year to October 1, the eggs (75-200) 

 are laid in a white foamy mass, which may be in an excavation 

 beneath stones, or other cover in shallow water, or may be under 

 stones, logs or cover near or away from the water. The latter masses 

 may be washed by rains into the nearby stream or pools. The eggs are 

 light yellow, 1/10-1/8 inch (2.5-3 ^mm.) in diameter. The largest 

 tadpole of Dr. Stejneger's series measures 1 7/8 inches (46 mm.). 

 The tadpole is dusky olive gray on the back, its venter white marbled 

 and mottled with dusky, its anal tube long median, its tail crests low 

 with edges parallel. The tooth ridges are 2/3, and muciferous ducts 

 are evident. Transformation is at 1 /2-1 1 /i 6 inch (13-17 mm.) during 

 many months of the year. (After Stejneger and Schmidt). 



Notes: Taylor and Wright found that their specimen had an 

 indistinct dorsolateral fold, larger choanae, larger triangular bony 

 prominences on which the vomerine teeth occur, dorsal coloration 

 without spots, and was different in other respects.
