Méhely, L.: Investigations on Paraguayan Batrachians

INVESTIGATIONS ON PARAGUAYAN BATRACHIANS. 227 form leather-brown above, indistinctly cross-barred on the limbs ; female with confluent darker marbling on the back and sharply pronounced crossbars on the limbs : lower surface white. 18. Hyla nasica COPE. Hyla nasica COPE, Proc. Ac. Philad., 1862, p. 354; BOULENGER, Cat. Batr. Sal., 1882, p. 376, und An. Mus. Genova, (2) VII, 1889, tab. II, fig. 4; BOETTGER, Zeitschr. f. Naturw., LVIII, 1885. p. 247. 'Hyla Vnuterii HENSEL (nec BELL.), Arch. f. Naturg., 1867, p. 157 (sec. spec. typ-)? Hyla granulata PETERS, Monatsber. Akad. Berlin, 1871, p. 651. 31 specimens, the largest 48 mm. from snout to vent. Tongue subcircular, slightly nicked behind. Vomerine teeth in two short series between the centres of the choanae. sometimes on a level with the anterior edge of the latter, close together, sometimes contiguous. Head rather small, about as long as broad. Snout subacuminate. longer than the orbit, once and a half to once and two thirds the diameter of the eye; canthus rostralis none; loreal region oblique ; nostril from the eye as far as the diameter of the latter. Interorbital space broader than the upper eyelid. Tympanum very distinct, its horizontal diameter slightly more than half the diameter of the eye. Fingers free or with a slight rudiment of web : first much shorter than second, latter distinctly shorter than fourth ; two metacarpal tubercles, the inner oval and smaller, the outer much larger and more or less heartshaped tin front longitudinally bisected by a more or less deep furrow); palmar surface more or less granular. Toes two-third webbed, third toe equal with the fifth : disks cross-elliptically, about two thirds the diameter of tympanum : subarticular tubercles moderate ; a larger inner and a smaller outer metatarsal tubercle ; no fold along the inner edge of the tarsus. Tibio-tarsal articulation mostly reaches between the eye and the nostril, sometimes the tip of the snout. Skin more or less, but always distinctly granulate above, strongly granulate beneath, finely on the throat; a fold from the eye above the tympanum, curved to the arm. Male with a median vocal sac. Coloration already by HENSEL very suitably described. Upper surface varies from dark rufous-brown through greyish- or yellowish-brown to light brown and ashgrey. Between the eyes generally a triangular dark spot arises from the outer edge of the upper eyelid as a narrow stripe and is directed backwards with its tip : this spot sometimes replaced by a dark band, sometimes broken into spots. On the scapular region mostly two isolate crescent-shaped markings, sometimes confluent to a triangle. 15*
