posteriorly; they also pass up the sides, becoming less and less distinct. 

 The upper parts appear entirely smooth, except an occasional and iso- 

 lated pustule on the side of the back. 



The general color above is of a light chestnut, with blotches of dark 

 chestnut; beneath, reddish-white. A dark chestnut line extends from 

 the snout through the nostril to the anterior can thus, and re-appears be- 

 hind the eye in an oval patch, involving the whole tympanum, and ex- 

 tending above the shoulder. A second similar patch appears on the 

 side, separated from the first by about the thickness of the arm. Be- 

 hind this again, and a little more on the back, is a smaller blotch, be- 

 hind which is one still smaller, and the region of the anus is tinged 

 with the same color; there thus appears to be a chain of these blotches, 

 extending, at about equal distances, from the anus to the eye, the two 

 last-mentioned lateral ones fully visible from above. There are indis- 

 tinct indications of darker blotches on the back, and suffusions of the 

 same round the scattered pustules referred to. The extreme edge of the 

 upper jaw is dark, but between this and the upper stripe, involving 

 nearly the whole side of the face below the eye, is an area of light chest- 

 nut, becoming clearer and brighter under the eye. A chestnut stripe 

 extends from the lower jaw up the arm, which has, besides, two or three 

 transverse blotches ; the femur, tibia and tarsus have each two or three 

 transverse fascite. The anterior face of the thighs is light chestnut; 

 the buttocks the same, with indistinct blotches of lighter. In some 

 si^ecimens the ground color is greenish lead color.

From the C. ornaUis the G. occidentalis differs in color entirely ; the 

 head is more acute, and the cleft of mouth deeper; the legs are longer 

 anil the granulation finer. 



This species is quite distinct from the C. ornatm, and does not appear 

 to have been named by any European author prior to Bouleuger. My 

 identification of it with the Ryla ocularis of Dautlin was based on a 

 plate representing it, or a species very similar to it, in one of the older 

 authors, but for which I have lost the reference. As pointed out by 

 Boulenger, it is clearly not the species so called by Daudin.
