L. Y. MÉH ELY the tip of which may be unite with the preceding spot,, or broken into smaller spots. On the sacral region two oblique, isolate dark markings, which may be confluent in a triangle or broken into smaller spots. Between these markings the back may be studded with smaller dark spots and especially the rufous-brown specimens are scattered all over the upper surface with yellowish rounded spots. The dark markings may be sometimes very indistinct or quite absent (2 among 31 specimens). From the nostril to the eye and on the postorbital fold a more or less distinct dark stripe, curved down to the arm. Upper lip irregularly greyish marbled ; flanks yellowish-grey, marbled with dark ; on the groin and anterior surface of thighs a stronger marbling ; hinder side of thighs yellowish. strongly marbled with black. Beneath whitish, uniform or throat mottled with brown. Limbs more or less cross-barred. I must remark that the «dark band from muzzle through tympanum to side» as COPE stated, can be seen among 31 specimens only on three young ones, but also in these cases not sharply expressed. Also the colour-form, figured last by Mr. BOULENGER is extremly rare (3 youngs among 31) and by no means characteristical for {he species. 19. Hyla phrynoderma BLGR. Hyla phrynoderma BOULENGER, Ann. Mus. Genova. 2 (VII), 1889, p. 248, tab II, fig. 3. Twelve specimens, the largest 41 mm. from snout to vent. In most respects agreeing with BOULENGER' s description, but differing as follows : — Vomerine teeth between the rather large choanae, generally on a level with the hinder edge of the latters. Snout' distinctly longer than the diameter of the orbit, at least twice as long as the diameter of the eye. Nostril much far from the eye than the diameter of the latter.* Eyes distinctly smaller than those of Hyla nasica COPE. Interorbital space distinctly broader than the upper eyelid. Tympanum two thirds or three fourths the diameter of the eye. Palmar surface and metacarpal tubercles quite the same as on Hyla nasica COPE ; plantar surface tubercular, subarticular tubercles strongly developed, outer metatarsal tubercle distinctly smaller than te inner. Width of disks three fourths or four fifths the diameter of the tympanum. Tibio-tarsal articulation reaches between the eye and the nostril, sometimes the nostril. Skin strongly warty on the upper surface, tubercular beneath. * The length of the snout and the width between the nostril and the eye are important characters in comparison to Hyla nasica COPE.
