HYLA SQUIRELLA Latreille 



Plate 9, figure 1 



Color description from life {JvMe 23, 1922). — General color of body 

 citrine drab. In general it has a greenish cast like tadpoles of Hyla 

 cinerea and H. gratiosa. Developing ventral flap betv/een hind legs 

 ecru-olive; throat from line of eye to eye to mouth same color. Area 

 behind gill area ocher red. Belly pigmented testaceous and chalced- 

 ony 3^ellow. These make a solid iridescence which on the sides and 

 across the middle venter becomes replaced Vvdth black. 



Tail. — Muscular part of tail dark olive buff. Muscular part without 

 prominent clusters of blackish spots. The dots are uniformly scattered 

 over the muscular part but slightly thicker near the tip. The tail 

 reminds one more of a Bamid tadpole tail in coloration. • 



Iris more or less black with a rim of testaceous or light coral red 

 and chalcedony yellow spots amongst the black. 



General appearance. — Tadpole small (32 mm.), full, and fairly deep 

 bodied. Tail long, tail tip acuminate, a flagelium present. Dorsal 

 and ventral crests well developed and tail in general deep. Dorsal 

 crest not as deep as the tail musculature. Dorsal crest extends on 

 to the body about to the vertical of the spiracle. Spiracle sinistral 

 directed upward and backward, well below the lateral axis, the 

 spiracular opening prominent elliptical lateral axis, is in dorsal
