This species, then, differs from Euj^repes by lacking supra- 

 nasal shields ; it would be a Mocoa^ but it has the scales 

 distinctly provided with three or four keels. 



The prgefrontal forms a broad suture with the rostral as well 

 as with the vertical. Only one fronto-parietal, notched behind 

 to receive the front part of the central occipital. Vertical five- 

 sided, nearly as long as broad. Nostril wide, in the centre of 

 the nasal. Ear-opening with two or three short lobules in front. 

 The middle of the body is surrounded by twenty-eight longi- 

 tudinal series of scales, subequal in size ; there are thirty-eight 

 scales in a longitudinal series between the fore and hind legs. 

 Six prjeanal scales, the middle of which are rather larger than 

 the others. The fore leg extends to the middle of the eye if 

 stretched forwards ; third finger a little shorter than the fourth. 

 The hind leg covers about two thirds of its distance from the 

 fore leg ; the fourth toe one fourth longer than the third. 



With regard to coloration it is very similar to Mocoa tri- 

 lineata. The dorsal parts are brownish, uniform or with dark 

 markings more or less confluent into a pair of longitudinal 

 bands. Sides black, with a well-defined white streak, one scale 

 broad, from the tympanum, above the shoulder, to the axil of 

 the hind leg. Lower parts uniform white. 



Two examples from the Feejee Islands. 



Mocoa viicropus. 



Praefrontal shield single, in contact with the rostral as well 

 as with the parietal. Five occipitals, of which the central is 

 as large as one of the anterior. Ear-opening very small, with- 

 out any lobules. The middle of the body is surrounded by 

 twenty-one longitudinal series of smooth scales ; six series are 

 dorsal and rather larger than the others. There are thirty- 

 five scales in a longitudinal series between the axils of the 

 fore and hind limbs. Four prseanal scales, the two middle of 

 which are twice the size of the lateral. Legs very feeble, but 

 five-toed; the fore leg does not reach the ear-opening if stretched 

 forwards ; fingers very short, subequal in length ; the third 

 and fom-th toes equal in length. Back light greenish olive, 

 with a few minute black specks, bordered on the side by a 

 deep-black band, which gradually passes into the greyish 

 coloration of the lower parts ; the latter are indistinctly marbled 

 with whitish. 



Two specimens, apparently young, from the Feejee Islands. 



Hinulia tetragonurus. 

 The prgefrontal forms a broad suture with the rostral as well 

 as with the vertical. Vertical five-sided, much longer than broad.
