238 MR. A. W. E. O'SHAUGHNESSY ON [Feb. I, 



This Goniodactyle is very conspicuous from its coloration. Tlie 

 variegation of the back is something like that seen on the head only 

 in Goniodactylus ocellatus, Grray, from Tobago, which seems to 

 have remained unnoticed since the acquisition of the single type in 

 the British Museum. The present species, from Ecuador, is quite 

 different from that described by Dr. Giinther as Qymnodaetylus 

 caudiscutatus, P. Z. S. 18.59, p. 410, which has a round ocellus at 

 the shoulder, but no vertical stripe. 



13. Goniodactylus buckleyi, sp. n. (Plate XXIII. fig. 3.) 



The granulation resembling that of the preceding; the scales of 

 the belly also similar. Mental large, and with two rounded gular 

 scales behind, but no distinct postmen tal. Six supralabials, five 

 infralabials. Tail with broad inferior scutes. 



Ground-colour greyish brown. Head variegated with black ; 

 back with two parallel longitudinal rows of black blotches, pointed 

 in front, and separated by the median line. A narrow white ver- 

 tical streak on the shoulder. Gular region, from the chin to the 

 chest, with alternating black and white oblique stripes converging 

 behind, and making a triangular pattern.

One specimen from Pallatanga and two from Canelos. 



This species offers most similarity to G. fuscus, but does not 

 possess the large postmental plate to which attention has been 

 drawn by M. Bocourt.

E. planiceps, Guich. op. cit. p. 21, pi. 6, a, b- 



A single specimen, 13^ inches in length, from Pallatanga. 



This is the first example of the above species received by the 

 British Museum, as those referred to it by Dr. Giinther in 1859 do 

 not really belong to it. 



15. Enyalius microlepis, sp. n. (Plate XXIV. fig. 2.) 



Head broad, rounded, its width just before the ear-opening being 

 nearly equal to its length from the tip of the snout to the occiput ;
