are deep brcwTi, with a prominent, wide, black interocular bar edged 

 anteriorly by a light line; on these the banding across the thighs and 

 particularly the irregular dark line on the front and back of thighs 

 appear particularly intense. Sometimes the dark interocular marking 

 has an anterior prolongation, while often there is a dark W-shaped 

 occipital marking to limit it posteriorly. 



Most of the series of H. strigilata from near the city of Rio de 

 Janeiro appear to be immature. The largest adult, USNM 96324, 

 measures 37 mm. in head and body length however, which puts it 

 within the average range of size for the series of H. hrieni from Alto 

 da Serra, Sao Paulo, although it is far below that of large females of 

 H. catharinae from Santa Catarina. The pigmentation on the Rio de 

 Janeiro series does not seem to be so intense as in the Alto da Serra 

 frogs. Three freshly collected adults from Agua Limpa, in Ouro 

 Preto, Minas Gerais, USNM 98021-3, are nearly as dark as the Alto 

 da Serra specimens. 



Remarks. — This species has a whispering voice, a note like tschiv, 

 tschw, tschw, often repeated. Adults are taken in trees, under stones, 

 and near still water. The species is very common on Tijuca in the 

 city of Rio de Janeiro, and is found elsewhere in the State, as well as in 

 Minas Gerais and in Sao Paulo. The gelatinous eggs have been 

 hatched into tadpoles which metamorphosed in several months in 

 Dr. A. Lutz's laboratory, A vial of tadpoles, USNM 96256, was taken 

 in September 1929. 



At Nova Friburgo the species was secured at night in a marsh where 

 the adults were floating in the shallow water or clinging low on the 

 bulrushes. When the collector Joaquim Venancio imitated their call, 

 they answered but did not come nearer.
