This species with the small feet and dilations of tlie H. crepitans, exhibits 

 the broader head of the H. leprieurii type, with the vomerine series in- 

 curved anteriorly as in the majority of species of the genus. X'le spur 

 on the thumb is smaller than in any species of the genus in the single 

 specimen at our disposal, and the antebrachial and tarsal folds are distinct. 

 Gular region smootli. There is a cross band between the eyes darker than 

 the ground color; the femora are crossed above by broad, rather indistinct 

 cross-bands very different from those on the posterior face, and similar to 

 those on the tibia ; in H. circumdatus, the same narrow black bands are 

 continued from behind to the front of the tarsus, without interruption. 

 Indistinct brown markings on the labial regions. 



The shorter hind limbs, distinguish this species from the H. crepitans.

Hypsiboas circumdatus, Cope. 



Journ. Ac. Nat. Sci. Philada. 1867, 201. 



Breadth of cranium at tympanum equal from end muzzle to opposite mid- 

 dle line of humerus ; canthus rostralis little marked, concave. Sacral 

 width twice in coccyx, three times from articulation of latter to opposite 

 outher canthus of eyes. Tympanum two-thirds occular opening. Vom- 

 erine series width divergent, oblique, scarcely curved ; palmation of band 

 to middle antepenultimate of foot to origin of penultimate phalange of 

 longest toe. Thumb an incurved unusually elongate osseous spur. Areol- 

 ations wanting on the breast, upper and under lip indistinctly yellow 

 margined. Femoral bands ten, blackish, very narrow and nearly sur- 

 rounding the leg : seven broader cross the tibia. 



This species differs from the H. pahnata in its much shorter palmation, 

 smaller size and different coloration ; from the H. crepitans, in its stouter 

 form, and much stouter feet and hands, and different coloration, compar- 

 ative measurements given under the head of the latter exhibit this.
