Hyla versicolor 331 



and sometimes almost vermillion about the eye; the golden and black spots 

 are more pronounced toward the tail; on the sides is a decided iridescence. 

 The eye is slightly bronzy. The venter in general is conspicuously white or 

 light cream and slightly iridescent. The belly is covered with fine golden 

 spots. From the gill-region forward the venter is greenish, a coloration pro- 

 duced by black and golden spots. The background of all the tail except the 

 base is scarlet or orange- vermillion. The base of the tail is like the body. 

 The tail is covered with black blotches, more prominent around the edges of 

 the crests. These blotches become much more numerous as the hind legs 

 develop. 



General appearance. Tadpole medium (46.6 mm.) full and deep bodied. 

 Tail very long, deep, tip very acuminate with a prominent fiagellum. The 

 dorsal crest is as deep as the musculature, and extends on to the body to the 

 vertical between the spiracle and the eye or to the spiracle. Spiracle sinistral, 

 directed more backwards than upwards, far below the lateral axis and visible 

 as an elliptical opening. Eye on lateral axis, in dorsal aspect on the lateral 

 outline and in consequence visible from the venter. Anus dextral, very near 

 or at the level of the edge of the lower tail crest. Muciferous crypts indistinct. 



Mouth parts: Teeth 2/3. Upper labium fringed with a continuous row of 

 labial teeth; the papillae extend above and inwards beyond the end of the 

 upper fringe for about 1/3 of the length of the upper fringe. The end of the 

 second row usually is even with the end of the upper fringe. The horny beak 

 is contained about 2 times in the upper fringe. The median space between the 

 lateral second upper labial rows quite short, 3.25-5 times the length of either 

 lateral row. The inner papillae extends under the third row of lower labial 

 teeth making at least two rows of papillae across the lower labial border. In 

 the lower labial corner there is a heavy papillary series of 2 or 3 rows not so 

 pronounced as in Hyla squirella or Hyla femoraUs. The lower third labial 

 teeth is long and is contained usually about 1.10-1.25 times in the first or 

 second row. The first or second rows about equal and 1.8-2.0 greater than 

 the horny beak. This species like Hyla femoralis and H. squirella has an 

 angulate upper fringe at its middle.
