THE BATRACHIANS AND REPTILES OF FORMOSA.

When Robert Swinhoe, in 1863, published the first List of the 

 Formosan Reptiles he had only 15 species to enumerate. After the 

 lapse of forty-four years the species of reptiles known to occur in 

 Formosa and its outlying islands had increased to 50, as given in 

 my Herpetology of Japan. To-day, three years after the issue of 

 the latter, the number has risen to 66. The record of the batrachians 

 is still more remarkable. Swinhoe collected only 4 species of batra- 

 chians in Formosa, as follows: llyla chinensis, Microhyla fissipes, 

 Rana plancyi, and Rana tigerina. In 1907 I recorded 9 species. In 

 the present paper there are enumerated 20 species. 



The activity in collecting these animals in Formosa since the pub- 

 lication in 1907 of the Herpetology of Japan has raised the total 

 number of batrachians and reptiles known to occur in that island 

 from 59 to 86 species. Of the 26 species thus added to the fauna, 

 no less than 15 are new species, and 8 represent genera hitherto not 

 known to occur on the island. 



These additions are recorded in seven papers by five authors, as 

 follows:
