or horny disks, the outermost being the largest, whilst the innermost, 

 which is situated at the base of the first finger, is inconspicuous. The 

 hind legs are slender, longer than the body and head together, by the 

 whole length of the fourth toe. The inner edge of the tarsus exhibits 

 a horny ridge. The sole of the feet is smooth. The outer metatarsal 

 tubercle is smaller than the inner one. 



The skin above, is provided with elongated, warty tubercles, ex- 

 tending over the head and dorsal region. The inferior regions are 

 covered with crowded, large, pavement-like glands, especially con- 

 spicuous on the abdomen. 



The ground color above, is sometimes uniform greyish-brown, with 

 transverse blackish maculae upon the legs. A blackish vitta extends 

 from the tip of the snout along the line of the canthus rostralis, 

 through the eye towards the shoulder, and tapering into a point. A 

 blackish triangular patch may be observed on the margin of the 

 upper jaw, in advance and beneath the eye, or else several spots all 

 along the branch of the maxillary. A yellowish-green band may be 

 observed from under the eye to the angle of the jaw. The lower 

 surface of the head is blackish-brown. The belly is yellowish-brown, 

 scattered all over with small black spots ; the legs reddish brown, like- 

 wise maculated ; the fingers and toes being reddish. 



In other individuals a spear-shaped spot exists upon the middle 

 region of the head, behind which, and all along the back, may be seen 

 a brownish-black band, anteriorly bifurcated, so as to admit the poste- 

 rior extremity of the cephalic spot. On each side of the dorsal band 

 is another, narrower band, of a yellowish-grey, stretching over the head, 

 and along the sides of the body ; from behind the orbits to the groins, 

 extends a still narrower, brownish-black, band. 



This species is a native of Australia : several specimens having 

 been collected on the southeastern coast of that continent.
