Coordinates 1236/9945 (Israel Topographical Map); latitude: 30° 32' 20" N; longitude: 34° 43' 36" E; western Makh- tesh Ramon, Israel; collected by Eviatar Nevo in 1954. Specific diagnosis. Same as for genus; sole known species of the genus. Description of the type material. A well preserved small frog represented by the original bones heavily impregnated by dark limonitic ferric oxides; distinctly flattened as a result of fossilization. Right hindlimb crushed proximally, and both hindlimbs lacking distally; in ventral aspect. Absent parts are described from F 41 a (PI. 6 E). General description. Skull (Fig. 10 C). The skull is large, wide and flat. It is some- what broader than long, slightly longer than the eight presacral vertebrae. The maxillary arcade is incomplete. A promi- nent rounded rostrum projects beyond the mouth. The quadrate region is posteriorly situated. The nasals are large, broad and kidney-shaped, rounded anteriorly and forming the rostrum (PI. 6 D); they meet anteromesially and diverge posteriorly to expose the central extension of the sphen- ethmoid; dorsally they have fanlike stria- tions. The frontoparietals form a broad azy- gous slab, strongly and totally ossified; they dominate the dorsal aspect of the skull and have a vaselike shape; anteriorly they contact the sphenethmoid; posteriorly they partly o
