Fig. 12. Hyalinobatrachium eccentricum, new species. A, B in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis

Fig. 12. Hyalinobatrachium eccentricum, new species. A, B: Right hand and left foot of male paratopotype (AMNH 159164). The raised or bubblelike ventral expansion of the web between fingers III and IV is an apparently novel structure, the bulla, that is shared with H. crurifasciatum (see fig. 15). C: Dorsal outline of the above hand, showing the distinct dorsal depression of the bulla. D: Right hand of the holotype (EBRG 3049). The bullae are not differentiated by pigmentation and are shaded for emphasis only. A possibility that the bullae might be induced by parasitism cannot be discounted and needs investigation (see Remarks in text). Scale line = 1 mm.
