bi'twotMi tlic rami. Loral s])aco riitlier excavated or eoncave. Nostrils* 

 iiiotk'rate, rather ()l)li<|uc; situated helow the caiitlms rostrahs, so us 

 to be fully visible beneatii the outline of the profile; they are situated 

 halfway between the auteiior <'aiithus of the eye and the tip of tlic 

 snout, and not so far forward as the til) of the lower Jaw; they are sep- 

 arated by about the diameter of the eye, or onefbnrth the distance Iw- 

 tween the rami. Kyes large, projecting, their centers nearer the hin-c 

 of the Jaws than the end of snout, the jmsterior njargins above the ric- 

 tus. Tympanum moderate, its i)osterior edge on a line with the jiostc- 

 rior end of jaws, its center raised, its longest diameter vertical, ami 

 about two-thircis that of the eye. The light line under the eye is piu- 

 longed into ii thickened glandular fold of skin which is interrujitcij 

 abruptly above the insertion of the arm ; the middle of the interval be. 

 tween this interruption and the end of the snout opposite the cent* r 

 of the eye. The distance between the rami rather less than to the end 

 of suout. Ui)per Jaw projecting moderately. 



The tongue is elongate<l, much longer tlian broad, free behind t'w 

 more than half its length and on tlu* si<les to the tip; the two cornua 

 moderately prominent. Internal iiarcs moderate, (;ir(;ular, and neanr 

 the anterior eanthus of the eye than to tiie external nostrils. Teeth in 

 two small slightly elongated patches, jihuted with their axes a litth" in- 

 clining backwards and aI'Miif intermediate between the nares, their an 

 terior edges being in tiie sann' line. They are al)out as far apart behiinl 

 as their anterior edges are from the naies on either side. The teeth n| 

 the ui>per Jaw extend back to the gape of tin.' mouth. 



The skin of the ui)pt'r and exposed portions of Ixxly and limbs is 

 more or less roughened by minute and close-pressed tubercles, with 

 here and there a largi'r interspersed. These do not appear to beat ;ili 

 glandidar or excretive. They are largest and most prominent, on ilif 

 sides and the posterior portion of the back, where they are generally 

 black. The posterior and inferior face of the thighs is granuiited inr 

 about two-thirds its length, as well as a small portion «)f tlu' bi'lly nn 

 the i)ubic region. The sides are scanjely granulated, although coarsely 

 pustulate; all the rest of the lower parts of Ixuly, including the con- 

 cealed surface, are perfectly smooth. The skin of the thigh is pierctd 

 by innumerable line pores. 



As already stated, there is a fold of skin as a continuation of the 

 light stripe along the edge of the upper jaw, and extending to a point 

 just above the middle of the arm, thickened behind. A rounded df 

 l)ressed ridge or fold of skin commences at the posterior end <tf tin- 

 eyelid, and, curving a little downwards to the tympanum, sends oil ,i 

 short branch along its posterior border, then continues along the si*' ^ 

 of the body (over the extremities of the transverse processes of tin- 

 vertebra), ceasing at the insertion of tin- hintl leg. 



The fore-legs are wt-ll developed : the foie arm shorter than the hand. 

 All the lingers are perfectly fie*'. 'I'lie third linger is longest, the lir.st
