Remaries. — The head and body of this species resembles 

 greatly Rana japonica, the snout being fully as pointed and 

 elongated, but the most remarkable character of this species is 

 the excessively lengthened hind legs, wliich are actually more 

 than twice as long as the head and body together. Even the 

 fore legs partake of this elongation though less markedly. The 

 coloration is that characteristic of the group. 



3. Rana limnocharis Wiegm. 



Numierous specimens from Taipa (No. 26) and Giilan (No. 

 25), Formosa, from Botel Tobago Island (No. 27) and from the 

 Pescadores (No. 28) testify to the frequent occurrence of this 

 species. In this large series there are three distinct types of 

 coloration, irrespective of locality, viz., back without median 

 stripe ; a very narrow median white stripe ; and a very broad 

 stripe of similar color. Otherwise the sj)ecimens agree well both 

 in structure and coloration. Comparison with Kiukiu specimens 

 shows no difference.
