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

 small groui)s between the choanae. 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. The 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. I^ead color or blue- 

 grey above, darker on the head region; ventral surface 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 4,0(50 meters above sea-level. 



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

 wann waters of a hot spring. In the type description Koslow^sky 

 (1895, p. 360) says: — "Seiior Rodolfo Hauthal los tomo enelarroyo, 

 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 !
