Geomolge, g. n. 



Tongue large, subcircular, free on the sides. Palatine teeth in 

 two arched, slightly angular series, separated by a narrow interspace. 

 Toes five. Tail cylindrical at the base, compressed at the end. 



Intermediate between Onychodacfylus and Ranirlens in the pala- 

 tine dentition ; distinguished, besides, from the former by the 

 absence of claws, from the latter by tlie shape of the tail, which 

 indicates a land animal. 



Geomolge fischeri, sp. n. (Plate XXXIX. fig. 2.) 

 Physiognomy that of Onychodacfylus japonicus. Head small, 

 longer than broad, broader than the neck ; snout rounded ; eyes 

 large, prominent; no labial lobes. Body cylindrical, four and a half 

 or five times the length of tlie head. Limbs in every respect 

 similar to those of Onychodacfylus japonicus, save the absence of 

 claws; the male likewise with tibio-tarsal dilatation. Tail longer 

 than head and body, cylindrical in its anterior half, becoming 

 gradually compressed and keeled towards the end, which is obtusely 

 pointed. Anal opening subcruciform, as in Onychodacfylus. Skin 

 smooth ; fourteen or fifteen costal grooves ; paratoids and gular fold 

 as in Onychodacfylus. Brown above, with blackish variegations, 

 most crowded on the sides, which also bear some whitish spots ; lower
