Elachyglossa. Novum genus Ranidarum. 



This new genus of the family Ranidce is nearly allied to. Oxyglossus, but differs 

 in having vomerine teeth, tympanum distinct, a large head, depressed body and 

 differently shaped hind feet. The diagnosis of the genus may beasfollows: Sternal 

 apparatus of the firmisternian type; upper jaw very distinctly toothe'd; diaphyses of 

 sacral vertebra not dilated. Pupil horizontal. Tongue free, narrow and entire. 

 Vomerine teeth present. Tympanum distinct. Fingers free, toes webbed, the fourth 

 toe much the longest; tips of fingers and toes feebly dilated into very small disks. 

 Outer metatarsals separated by web. Omosternum with a bony style, sternum a 

 cartilaginous plate. Terminal phalanges of fingers transversely dilated; no intercalary 

 ossification between the distal and penultimate phalanges.

Figures; see page 14. 



Vomerine teeth in two rather long oblique series behind the small choanse. 

 Tongue very small, narrow, extensively free, and bluntly pointed behind, very small 

 in proportion to the wide mouth. Head large, broad, and flattened; the greatest 

 breadth of the head equal to the distance between the tip of the snout and the hind 

 margin of the tympanum. Snout rounded, a little longer than the diameter of the 

 eye; canthus rostralis indistinct. Loreal region oblique, deeply concave. Interorbital 

 space broader than the upper eyelid. Nostril nearer the tip of the snout than the 

 eye. Tympanum distinct, 3 /s diameter of eye. Fingers free, rather long, the first 

 not quite reaching the tip of the second; toes nearly entirely webbed, the web 

 reaching the disks, except in the 4th toé, two joints of which are free; the web of 

 the other toes as well is deeply emarginate; the 4th toe considerably longer than 

 the 3d and 5th; tips of fingers and toes with very small disks; terminal phalanges
