Variation. — The variation of this and allied species has been men- 

 tioned above under the general discussion of their status. It may 

 be repeated here that the relative length of the first and second fingers 

 is not constant. Thus, in the type, " the first finger being laid against 

 the second does not extend quite so far as the latter." The same rela- 

 tion holds in over No. 11348, but in my two topotypes these propor- 

 tions are reversed. The second of these has the whole underside 

 almost uniform whitish with a few scattered dusky spots. 



The females differ from the males in this and allied forms in the 

 less-developed fore legs and somewhat larger webs between the toes. 

 They also lack the nuptial pads of asperities on the fingers described 

 above which characterize the males not only during the breeding sea- 

 son but for a long time after, as shown by my specimens which were 

 taken in September. 



Habitat. — xis indicated above, the only positive locality whence we 

 have undoubted specimens of this species is the neighborhood of 

 Tokyo and Yokohama, to which must be reckoned ''Mount Fuji." 

 The locality "Dagoshima" attached to a specimen in British Museum 

 which was collected by Doctor Anderson on May 24, 1884, I have 

 failed to find on any map.'* A great amount of carefid collecting 

 and critical identification will be necessary before the range of this 

 and allied forms in Japan can be determined.

^Unless it be meant for Dogashima, near Miyanoshta, in Hakone, about 1,300 feet 

 above the sea, consequently not far from the other localities from which we have 

 specimens.
