BATRACHIAANOURA 59 



SPEC. CHAR. Subdigital disks moderate in both pairs of limbs. Red- 

 dish-purple, with a dorsal light line, and maculated with black. 



DESCR. Of this species there was but one specimen collected, now 

 in a very precarious state of preservation. In its general aspect it 

 resembles more H. lieros than H. ritiensis, but is easily distinguished 

 from the former by a much greater dilatation of the extremities of 

 fingers and toes. The membrane at the base of the toes is also more 

 developed than in H. heros. 



The ground color is yellowish-purple, more intense along the sides. 

 The upper surface of the head and body exhibits a golden hue, 

 and along the middle region of the back is a whitish, narrow vitta, 

 extending from the snout to the posterior extremity of the body. On 

 each side of that dorsal line are blackish maculae, largest upon the 

 head and anterior part of the body, and smallest along the sides. The 

 legs are barred with black. The iris is purplish. 



Found, with the preceding species, on the Feejee Islands. A 

 drawing from life having been made by Mr. Drayton, its form and 

 general appearance were thus preserved.

 Toes webbed, aud the fingers occasionally also.
