Hinder side of thighs marbled with black and white, but the white spots near the lower edge smaller and arrenged in a rather indistinct longitudinal row. The cross-bars on the middle surface of the limbs interrupted with violet-rose. Throat very finely punetulated with brown, belly and other parts white. It is known that HENSEL observed a brown and blue or blue and grey colour on the specimens collected by him in the forests of Rio Grande do Sul.* I think that this blue colour, which perhaps is changed into violet-rose through the influence of the spirit, could be regarded as the nuptial-dress of the male, like our Rana arvalis NILSS. It is true that all (10) of HENSEL'S specimens bear the same colour and it could not be assumed that they all were males, it is striking, however, that in the following species the male only is rose coloured. It is perhaps the same case with Leptodactylus rhodonotus GTHR.,** which differs from Leptodactylus mystaciuiis BURM. — according the descriptions — only by the absence of the ventral discoidal fold and the heart-shaped tongue.

Berlin, 1872 1873], p. 199) that SPIX'S both specimens, exposed on the plate III by the figures 1 and 3 as Bana mystacea , belong to «Rana (Cystignathus) typhonia Dan din», but only the latter (fig. 3l can be drawn to this species, while the former (fig. 1) represents quite a different one and is the type of SPIX'S Rana mystacea, which species must be restituted instead Leptodactylus poecilochilus COPE.
