This animal is about intermediate between the forms of the nebu- 

 losus group (which inhabit Hondo, Kiusiu, Shikoku, and the islands 

 in the Korean straits), and peropus of the high interior of Hondo. It 

 may therefore be taken to represent the mainland stock from which 

 both these island groups have arisen. Its intermediate nature is seen 

 in its dentition, its coloration, and its proportions. It could be con- 

 fused more readily with tagoi, ikishimae, and peropus, than with 

 tsuensis, nebulosus and vandenburghi. 



All the nebulosus group have vomerine series as long as or longer 

 than the maximum length found in leeckii. Tagoi has a rather indi- 

 vidual coloration which should distinguish it easily. Ikishimae has a 

 longer vomerine series and nearly always has a yellow stripe on the 

 middorsal line of the tail which lecchii never has. Peropus has a 

 vomerine series as short as the shortest in lecchii, fewer costal grooves, 

 longer legs, and a different coloration. 



Besides the following localities Abe (1921) has recorded it from 

 Hokkansan and Heijo.
