O osteocrânio de Proceratophrys boiei (Wied-Neuwied), P. appendiculata (Günther), P. melanopogon (Miranda-Ribeiro) e P. laticeps Izecksohn & Peixoto (Anura, Leptodactylidae) The osteocranium of Proceratophrys boiei (Wied-Neuwied), P. appendiculata (Günther), P. melanopogon (Miranda-Ribeiro), and P. laticeps Izecksohn & Peixoto, (Anura, Leptodactylidae)

Foram comparados alguns ossos do crânio de quatro espécies de Proceratophrys Miranda-Ribeiro, 1920 que compartilham longos apêndices palpebrais, como sejam: P. boiei (Wied-Neuwied, 1825), P. appendiculata (Günther, 1873), P. melanopogon (Miranda-Ribeiro, 1926) e P. laticeps Izecksohn & Peixoto, 1981. Com base na forma dos frontoparietais, (com cristas laterais elevadas), na posição dos cantos dos quadratojugais em relação ao plano vertical dos côndilos occipitais, na ornamentação das superfícies cranianas (com tubérculos e grânulos), e na presença de fossetas maxilares posteriores ventrais, P. boiei, P. appendiculata e P. melanopogon foram consideradas em um mesmo grupo. P. laticeps, entretanto, por apresentar arcadas temporais completas (semelhante a Ceratophrys Wied-Neuwied, 1824), cantos dos quadratojugais posteriores ao plano vertical dos côndilos occipitais, superfícies cranianas rugosas e ausência de fossetas maxilares posteriores ventrais, é considerada pertencente a um grupo separado.<br>Skull bones of four Proceratophrys Miranda-Ribeiro, 1920 species sharing long dermal appendages on eyelids - P. boiei (Wied-Neuwied, 1825), P. appendiculata (Günther, 1873), P. melanopogon (Miranda-Ribeiro, 1926), and P. laticeps Izecksohn & Peixoto, 1981 - are herein studied. Proceratophrys boiei, P. appendiculata and P. melanopogon share higher lateral crests on the frontoparietals, quadratojugal corners similarly positioned in relation to the vertical level of the occipital condiles, cranial bones with granules and tubercles, and maxillaries with ventro-posterior pits, hence being considered members of a single group; P. laticeps, given the presence of temporal arcades (similar to Ceratophrys Wied-Neuwied, 1824), quadratojugal corners posterior to the vertical level of occipital condiles, wrinkled skull bones, and maxilaries without ventro-posterior pits, is nonetheless considered as a member of a distinct group

Descrição da larva de Scinax similis (Cochran) com notas comparativas sobre o grupo "ruber" no sudeste do Brasil (Amphibia, Anura, Hylidae) Description of the larva of Scinax similis (Cochran) with comparative notes on the Scinax ruber group in Southeastern Brazil (Amphibia, Anura, Hylidae)

<abstract language="eng">The larva of Scinax similis (Cochran, 1952) is described from Ilha do Fundão (Rio de Janeiro, Rio de Janeiro State, Brazil). Comparisons with other species of the group that occur in Southeastern Brazil are added. The larva of S. similis can be distinguished by the following diagnostic features: (1) eyes large in relation to body length (17,3%), body height (26,8%), and body width (29,7%), interocular distance three times larger than eye diameter; (2) lower beak with two transverse stripes, proximal half white and distal half black
