298 Mr. G. A. Boulenger on new or 



Liuperus elegans^ Peters, of which I examined the type in 

 the Berlin Museum, belongs to the genus Hylodes, and is 

 very closely allied to H, hogotensis, Peters, from which it 

 differs in the smaller digital expansions. The vomerine 

 teethj very indistinct, appear to be in two small rounded 

 groups behind the line of the choanse. Liuperus nitidus^ 

 Peters, is probably likewise not a Paludicola ; but I could 

 not examine the sternum. 



Hyla marginata^ sp. n. 



Tongue broader than long, entire, posterior fourth free. 

 Vomerine teeth in two transverse oval groups, close together, 

 on a line with the posterior border of the choanse, which are 

 of moderate size and much larger than the eustachian tubes. 

 Head moderate, broader than long ; snout rounded, shorter 

 than the diameter of the orbit ; cauthus rostralis angular ; 

 loreal region not very oblique, concave ; nostril nearer the 

 end of the snout than the eye ; interorbital space broader than 

 the upper eyelid ; tympanum distinct^ half the diameter of 

 the eye. Fingers one-third webbed ; a distinct rudiment of 

 poUex ; toes about three-fifths webbed ; disks a little smaller 

 than the tympanum ; subartlcular tubercles moderate ; no 

 tarsal fold. The tibio-tarsal articulation reaches halfway 

 between the eye and the end of the snout. Skin smooth ; 

 belly with large granules ; throat indistinctly granulate. 

 Upper surface of head and tibia and back finely powdered 

 with brown on a colourless ground ; a few small dark brown 

 spots on the head and back, one on each upper eyelid ; a dark 

 brown line from the end of the snout, along the canthus 

 rostralis and supraciliary edge, above the tympanum, and 

 along each side of the body as far as the sacral region, also 

 along the outer side of the forearm and tibia ; a transverse 

 dark brown streak, edged above with white, above the vent 

 and at the heel ; a white line round the upper lip ; lower 

 surfaces colourless. From snout to vent 50 millim. 



Mundo Novo, Rio Grande do Sul. 



A single female specimen, collected by Hr. Bischoff. 



Apparently related to H. ruhicundula, R. & L. . 



Ilyla Bischoffij sp. n. 



Tongue circular, entire, and slightly free behind. Vome- 

 rine teeth in a strong, scarcely interrupted, transverse series, 

 on a line with the hinder edge of the choanse, which are of 

 moderate size and larger than the eustachian tubes. Head 

 rather large, rather strongly depressed, slightly broader than
