Obsery. — The physiognomy of this species is widely distinct from 

 that of Elosia nasuta, thoug-h both species are closely allied by their 

 structure. The first trait which strikes most in their differentiation 

 consists in the shortness of its legs, which are, nevertheless, slender. 

 Next it will be observed that the body is shorter, when compared to 

 the head. The head itself is more bulky and its upper surfece more 

 inclined on the snout. The latter is more obtuse, more elevated, more 

 inwardly truncated. 



Descr. — The head, somewhat broader than long, forms more than the 

 third of the length, the limbs excluded. The occipital region is convex- 

 and the distance from the eyes to the snout very much inclined for, 

 wards. The terminal line of the snout, seen from above, is that of 

 an obtuse triangle, still more open than in E. nasuta ; the line of 

 the canthus rostralis is also less concave. The nostrils, subcircular 

 or subelliptical, are less prominent, though situated midway between 

 the anterior margin of the eye and the extremity of the snout. The 

 eyes, themselves, are large, subelliptical ; their horizontal diameter is 

 twice the distance between them and the nostrils. The upper lid is 

 smooth, but its horny margin does not extend along the canthus ros- 

 tralis. The tympanum is of medium size, and its diameter greater 

 than the radius of the eye, as is the case in the preceding species. 

 The mouth is broad and large ; the tongue suborbicular, rather thin, 

 especially upon its margin. The vomerine teeth constitute two small 

 and oblong groups situated between the inner nostrils, and somewhat 

 larger than in E. nasuta. The inner nostrils are subcircular, and also 

 larger than in E. nasuta. The openings of the Eustachian tubes are 

 smaller than the inner nostrils, though larger than in E. nasuta. 



The legs are slender, but shorter than in E. nasuta, and the dilata- 

 tions of the fingers and toes less developed. The forelegs, when
