Iq addition, the actual length and width of head in flavopictus fall 

 below the critical limits of labyrinthicus on the statistical chart, thus 

 indicating that the head may be both shorter and narrower ia pro- 

 portion to the body length ia Jlavopictus than in labyrinthicus. More 

 specimens from Itatiaia are needed to settle this point finally, however.

Description. — Adult male, USNM 121286, Jurii Mirim, Sao Paulo. 

 Vomerine teeth in two exceedingly heavy, curved, nearly contiguous 

 arcs between and behmd the choanae; maxillary teeth apparent; 

 tongue almost two-thirds as wide as mouth-opening, widely oval, 

 with a notch on its free posterior border; snout short and blunt when 

 seen from above and in profile, the upper jaw scarcely projecting 

 beyond the lower; nostrils superolateral, slightly projecting, their 

 distance from end of snout equal to their distance from eye and to the 

 interval between the nostrils. Canthus rostralis bluntly rounded, the 

 loreal region concave, and flarmg out to the upper lip. Eye large and 

 prominent, its diameter a little greater than its distance from nostril; 

 interorbital diameter equal to that of upper eyelid, slightly less than
