in regard to the more than usually copious webbing ; it is not 

 accessible at present, and I cannot give further particulars about it, 

 but it is the frog exhibited by Mr. Masters at the meeting of this 

 Society in March, 1886 [Proceedings (2), I. p, 238]. Specimens of 

 this species from the Blue Mts. are normally webbed, but are longer 

 in the legs than the type, like my northern river specimens. 



In endeavouring to find a place in our systematic lists for such 

 specimens as the above, one has choice of two alternatives ; either 

 to consider that they are representatives of new species and to deal 

 with them accordingly, or, as I think the more desirable course, 

 to treat them as varietal forms, and to note them as such. With 

 the advantages which residence in the country naturally gives in 

 the way of acquiring some knowledge of certain species in their 

 natural haunts, and of obtaining with greater facility perhaps 

 larger series of specimens of other species than naturalists abroad 

 can very often have at their disposal, it has ceased to cause me 

 surprise that I sometimes meet with individuals whose characters 

 refuse to come perfectly and exactly into the line as laid down in 

 the text-books ; or that characters which seem to be of more or 

 less considerable specific importance when only a few specimens 

 have been available, should sometimes turn out to be variable 

 when larger series of specimens are examined.
