BATRACHIAANOURA. 19 



tympanum is subcircular; its diameter being a little smaller than that 

 of the eye, and contained once and a half between the orbit and the 

 extremity of the snout. The mouth is very large ; the upper jaw- 

 being emarginated, and the tongue oblong, narrow, and moderately 

 forked. The inner nostrils are conspicuous and transversely elongated. 

 The vomerine teeth, situated between and somewhat behind the latter, 

 constitute two elliptical groups, inclined sideways. The openings of 

 the tubes of Eustachi are subcircular and proportionally large. 



The body itself is elongated and depressed. The limbs are long 

 and slender, especially the hind ones, which are longer than the body 

 and head together, measured from their origin to the base of the 

 tarsus. The feet themselves are as long as the thighs. The fingers 

 are long and stout ; the innermost, or thumb, is a little longer than the 

 second, which is the shortest ; the outermost is about the same length 

 with the first. Their terminal phalanx is knob-shaped beneath, 

 resembling in that respect the tubercles which may be observed 

 under the articulations of the phalanges. The palm of the hand is 

 smooth ; two elongated and flattened horny disks may be seen upon 

 its base, large, though not prominent. The interdigital membrane 

 is deeply concave between the toes, and does not quite reach their 

 tips. Tubercles are observed under the articulations of the pha- 

 langes. The tarsus beneath is perfectly smooth, and provided only 

 with a small horny process at the base and outer edge of the first 

 toe. 



The skin is smooth all over the body and limbs, above and below. 

 Two longitudinal zones of minute pores may be seen extending from 

 behind the orbits, immediately above the tympanum, to near the pos- 

 terior region of the body. 



The color above is greenish-yellow, with golden reflections along 

 the upper jaw, dorsal region, and on the limbs. Two dorsal black 

 bands extend over the series of pores. A narrow black vitta exists 

 on the line of the canthus rostralis, between the nostrils and the eye, 

 and another along the upper and posterior margin of the tympanum. 

 The sides of the abdomen, and sides of the legs also, are reddish-orange. 

 Black spots and dots are scattered all over the body, head, and limbs, 

 largest posteriorly. The upper lid, the snout, and the edge of the 

 upper jaw are dotted with black. The iris is golden. The membrane 

 uniting the toes is purplish or violet. Beneath, dull yellowish-green, 

 maculated with blackish on the inferior surface of the head, from the
