298 Mr. A. W. E. O'Shaughnessy on new Species of 



wedge-shaped and pentagonal plates, which occupy the rest of 

 the space as far as the first gular row of scales, of which there 

 are three small and three large before the collar. 



Dorsal scales narrow, elongate, each scale elevated into a 

 ridge in the middle, in 36 transverse series between the occi- 

 put and the root of the tail ; scales of the sides much smaller, 

 round, convex or granular on side of neck and axillary region ; 

 of belly in 10 longitudinal series, the middle ones square, the 

 outer ones narrower. Tail with scales like the back and the 

 belly. Prasanal scutes 2, 4. 



The fore limb reaches to the middle of the eye, the hind 

 limb two thirds the length of the side. 



Brown above ; a longitudinal stripe of lighter brown edged 

 with black on each side of the back from the occiput to the 

 tail. Ten or eleven conspicuous ocelli, white in the centre, and 

 surrounded by a black ring, along the side of the body ; beneath 

 each one of these a smaller white spot is visible. All the 

 ventral scutes and those of the under surface of the limbs 

 black in the middle, white on the edges, the black forming 

 longitudinal stripes. 



One specimen, collected by Mr. Buckley at Intac, Ecuador.

The lizard here described evidently resembles closely the 

 description given of E. (Oreosaurus) luctuosus by Dr. Peters 

 in Abhandl. Ak. Berl. 1862, p. 205, with which it is perhaps 

 identical. Dr. Peters states that there are 43 transverse series 

 of scales between the occiput and the root of the tail, and 

 has not given a figure of the lizard. I am inclined to think, 

 however, that I have only redescribed that species. 



Cercosaura {Pantodactylus) vertebralis, sp. n. 



A single broad internasal plate, separated from the frontal by 

 a pair of fronto-nasals ; frontal very short, scarcely longer than 

 the internasal, and only half the length of the supraorbital re- 

 gion; two fronto-parietals as long as the frontal, and contiguous 

 throughout the whole of their length ; an interparietal and two 

 parietal plates, followed by three occipitals; two series of large
