I was so fortunate as to be able to compare five specimens of the 

 present species with the type and three other Formosan specimens of 

 M. fissipes in British Museum. The former consisted of two speci- 

 mens brought by Fryer's collector from the Riu Kius (Brit. Mus. 

 87.1. 31. 43-44), and three collected by Hoist in the mountain re- 

 gions of Motobu, about 30 miles north of Nafa, Okinawa shima (Brit. 

 Mus. 92. 9. 3. 24-26). The chief difference between the Formosan 

 specimens and those from Riu Kiu consists in the presence of a dis- 

 tinct, though small, basal web between the toes and in the apprecia- 

 bly greater development of the metatarsal tubercles in the latter. 

 Other differences which I thought that I had detected between my 

 type-specimen and the original description of M. fissipes did not hold. 

 Thus, the smoothness of the sides or presence of slight warts does not 

 seem to be of an;y moment, and the coloration is essentially alike. 

 The X and V shaped marks of the type, as described by Boulenger, are 

 only due to the somewhat darker outlining anteriorly and posteriorly 

 of the median dorsal patch; the median white dorsal stripe of the 

 type of M. okinavensis is only shown by one of Fryer's specimens.
