basis of the last phalanges, only in the fourth toe webbed to the base of the

 in the skin, especially distinct on the outer edge of the fifth toe. Tibiotarsal 

 articulation reaches the tip of the sncut. Upper surface rugose, upper lip, 

 appendages, and urder surface smooth. A strong fold from the posterior 

 edge of the eye to the corner of the mouth. Color above brownish grey, 

 spotted with dark brown, the tubercles all dark brown. Ventral surface

Diagnosis (extracted frcm original description). Vomerine teeth in two 

 small groups between the chcanae. Toes more than half webbed, a free border 

 extending along the interior edge of the tarsus, and on the outer side of the 

 interior toe. JThe leg extended forward reaching with the tibiotarsal articula- 

 tion the angle of the mouth. Skin smooth, covered with numerous horny 

 tubercles on the chest, back, abdomen, and appendages. Lead color or blue- 

 grey above, darker on the head region; ventral suiface dirty yellowish white; 

 some specimens mottled with dark tone on the posterior part of the ventral 

 surface, all specimens uniform above. 



Habitat. The type-locality: Andes of Catamarca, Argentina, 

 Aguas Calientes, a streamlet 4,060 meters above sea-level. 



Remarks. Oddly enough this species has been found only in the 

 warm waters of a hot spring. In the type description Koslowsky 

 (1895, p. 360) says: — ^"Senor Rodolfo Hauthal los tomo en el arroyo, 

 cuyas aguas siempre conservan una temperatura de veinte grados, 

 Celsius." How different from the frigid waters of Lake Titicaca, 

 the home of the closely related T. culeus !
