BATRACHIAANOTJRA. §1 



it is almost subelliptical, its sides being rounded, and the snout not 

 very prominent, itself rounded above and declivous upon the sides. 

 The nostrils are oblong, situated immedintely below the canthus ros- 

 tralis, and nearer the extremity of the upper jaw than the anterior 

 rim of the orbit. The eyes are large, prominent, their longitudinal 

 diameter being greater than the rhinic distance between their anterior 

 rim and the nostrils. The upper lid is smooth, like the skin of the 

 head and back. The interocular space is a little less than their 

 diameter. The tympanum is conspicuous, circular, its diameter being 

 half that of the eye. The mouth is large, and so is the tongue, which 

 is regularly elliptical, and but slightly emarginated, slightly free pos- 

 teriorly and laterally. The inner nostrils are very large, subtrian- 

 gular ; the openings of the Eustachian tubes are much smaller. The 

 vomerine teeth constitute two oblong groups, situated exactly between 

 the inner nostrils; subtransversal, separated from each other by a narrow 

 space, and approximating closely to the inner edge of the nostrils. 



The body is iSattened like the head, broad anteriorly, and tapering 

 posteriorly. The limbs are slender and long, compared to the body. 

 The anterior ones, however, when brought alongside to the body, 

 only reach the groins with the extremities of the fingers. The 

 latter are entirely free, depressed, provided with tubercles under their 

 articulations. The disks under their extremities are oblong and of 

 medium size. The palm of the hand is subgranular, and provided at 

 its base with two flattened disks almost blended with the skin. The 

 hind legs are longer than the body and head together, by two-thirds 

 of the tarsus and the remaining portion of the foot. The tarsus 

 exhibits a small membranous ridge along its inner edge. The sole 

 of the feet is very minutely pustulous. The toes are webbed up to 

 the middle of the last phalanx (on the fourth toe to the end of the 

 last but one) ; but the membrane is very deeply emarginated. The 

 tubercles under their articulations are quite conspicuous. The termi- 

 nal expansions are fashioned like those of the fingers, being rather 

 small compared to the size of the animal. The skin is smooth 

 throughout ; small glands may be seen on the side of the chest, on 

 the abdomen, and under the thighs. 



The color above, is green, with yellowish, tints about the eyes, the 

 sides of the abdomen, and legs. A narrow black vitta extends along 

 the line of the canthus rostralis. A black, much broader vitta, 

 extends from behind the eyes to the sides beyond the shoulders. The
