aEHYRA VOKAX. 275 



Spec. Cpiar. — Fingers and toes broad and rather short. Dorsal scales 

 small and uniform. Abdominal scales subpyramidal in outline. 

 Brown or grejish-brown above, maculated with black ; beneath 

 whitish, dotted with black. 



Syn. — Gthyra vorax, GrRD. in Proc. Acad. Nat. Sci. Philad. November, 1857. 

 Moco, Feejees. 



Observ. — This species is closely allied to the preceding one, but 

 appears to grow to a much larger size. It is a stoutly built, strong 

 animal, of a voracious disposition. The naturalists of the Expedition, 

 who have observed it alive, state that it will even spring at a person, 

 who may approach it while in captivity, and inflict a very severe 

 bite. 



Descr. — The body is depressed, broader than deep, and thickest 

 upon its middle region. The granulation of the back is proportionally 

 coarser than in the preceding species ; a fact easily ascertained by the 

 comparison of specimens of equal size of both species. The abdomi- 

 nal scales, on the other hand, are smaller. The granules on the upper 

 surface of the head, neck, and temporal region are a good deal smaller 

 than on the back. The scales upon the carpus and tarsus are smaller 

 than in the preceding species, as are also those on the inferior surface of 

 the leg. The femoral scales are equal in size, and alike in outline to 

 the abdominal ones; the series of femoral pores, of either side, are con- 

 tiguous upon the mesial line : they are composed of nearly twice as 

 many pores as in the preceding species. 



The tail is subcorneal, somewhat depressed, constituting about the 

 third, or rather more, of the total length. A single specimen has it 

 preserved. Its upper surface is covered with granular scales, larger 

 than those of the back, increasing in size laterally, becoming quite 

 large along the middle of the inferior surface, assuming the aspect of 

 scutellae, though irregular in outline, and variable in size. 



The head is quite depressed, and, viewed from above, it is pyrami- 

 dal in its outline. The nostril is subpyriform, and situated immedi- 

 ately above the commissure between the rostral and the first labial 

 plate. Three small plates may be termed internasal, from their posi- 

 tion one above each nostril, the third in a notch of the rostral, and 

 between the two just mentioned. There are fourteen upper labials,
