Description. — A translation of the original description follows: 



Snout rounded, its tip perfectly vertical in profile. Canthus rostralis distinct. 

 Nostrils lateral, near tip of snout. Diameter of eye six-sevenths that of snout, 

 equal to distance between anterior angles of eyes. Tympanum distinct, its 

 diameter one-half that of eye; tympanic region reentering, which makes the head 

 circular. Mouth with curved lateral profile; its anteroposterior diameter one- 

 half that of its transverse diameter. Vomerine teeth projecting in two contiguous 

 groups between the choanae, scarcely extending behind them. Tongue large, 

 heart shaped. Fore limb scarcely reaching to the coccyx; fingers half -webbed, 

 in the following order of increase: 2, 1, 4, and 3; subarticular tubercles projecting; 

 inner carpal tubercle greatly elongated, the external one absent. When hind 

 leg is brought forward, heel reaches eye. Toes webbed, in the following order: 

 1, 2, 3, 5, and 4; web of second toe passes the excessively vestigial first and reaches 

 the inner side of tarsus. Subarticular tubercles present, the inner metatarsal 

 tubercle distinct, although small and oblong, the outer one vestigial. Skin of 

 head free; all the upper parts smooth, with some scarcely apparent ridges in the 

 periostial region of the marsupium; throat finely rugose; abdomen and lower 

 surface of femur granular. Color that of coflfee (faded in alcohol to Isabella 

 color) ornamented with a black ellipse, with the center spotted, above the eyelids 

 and another above each shoulder, a double median black stripe in the sacral 

 region, and an elliptical pattern of small black spots extending from the shoulder 

 to the mouth of the marsupium, where there is a black X, its two upper (anterior) 

 arms external and its lower (posterior) arms internal to the mouth of the mar- 

 supium. Above the coccyx another interrupted ocellus, following a large trans- 

 verse spot. A narrow rostropleural line coming from tip of snout through nostrils 

 and margin of eyelids, bordering the tympani, and curving backward to the sides 

 of the abdomen; in this oculo-abdominal distance the ornament enlarges into a 

 regular fringe with very beautiful effect; another black line margins the lower 

 side of the maxilla. Fore limb fringed externally with a black fretwork up to 

 the outer finger; hind limb banded on upper part of femur and leg and up to web 

 with another fretwork analogous to that of arm, up to the two outer toes. Body 

 75, leg 105 mm. One female coming from Macah6, State of Rio, by Sr. Ernesto 

 Garbe. It has a pouch filled with about 24 eggs 8 mm. in greatest diameter.
