FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 177 



whereas length and width are equal in most specimens of senicula. 

 These facts, taken in conjunction with the light posterior femur in- 

 vaded by the dark crossbands, renders this individual slightly atypical. 



A male from Bonito, Pernambuco, is practically identical with the 

 described specimen from Angra dos Reis except for its slightly greater 

 finger webs. 



Remarks. — The life history of this species is unknown. The voice 

 has not been recorded. Although Corcovado, in the city of Rio de 

 Janeiro, is the type locality, being the source of Burmeister's specimen 

 on which Cope based the name senicula, no specimens from that city 

 are in the collections at hand.

DescriiHion. — Adult female, ZMB 7472 (type of H. microps), Nova 

 Friburgo, Rio de Janeiro. Vomerine teeth in two long, heavy, nar- 

 rowly separated, transverse patches lying between the posterior 

 borders of the very small choanae; tongue about two-thirds the width 

 of mouth-opening, cordiform, with a distinct notch on its free posterior 

 border; snout short, truncate when viewed from above and in profile, 

 the upper jaw scarcely extending beyond the lower; nostrils antero- 

 lateral, scarcely projecting, situated almost at the end of the snout. 

 Canthus rostralis rounded but well defined because of the concave 

 loreal region below it. Eye large and very prominent, its diameter 

 1}^ times greater than its distance from end of snout; interorbital diam- 

 eter equal to width of upper eyelid, equal also to width between 

 nostrils. Tympanum distinct, a little less than one-half the eye di- 

 ameter, separated from eye by an interval equal to about one-half
