78 HERPETOLOGICAL NOTES. 



size and scattered, but more commonly in small freckles ; 

 lower parts creamy white. The yellow marks are fre- 

 quently replaced by white ; (6) general colour much lighter 

 brown, the yellow or white spots or bands being replaced 

 by pale brown or dirty white ; otherwise as in var. a. In 

 some young examples the upper parts are so profusely 

 blotched with white as to almost entirely hide the dark 

 ground colour, but, as a rule, the pattern of colouration^ 

 as given in the description of var. a, is not materially 

 departed from." 



" This Tree Frog appears to be common in the St. 

 Joseph's River district, since no less than twenty-six 

 specimens were sent down by Sir Wm. Macgregor, to whom 

 I have much pleasure in dedicating this handsome species. 

 The largest example measures 30mm. from snout to vent." 

 (Ogilby.) 



The affinities of this frog are with H. thesaurensis, 

 Ptrs., differing in the amount of webbing, the length of the 

 hind-Hmb and the position of the vomerine teeth. The 

 colouration, too, although of the same type, differs in details. 



The distribution credited to H. thesaurensis at present 

 is German New Guinea and the Solomon Islands. The 

 Papuan record is based on a specimen determined by Dr. 

 von. Meheh' as thesaurensis, but which I have not any 

 hesitation in pronouncing to be a specimen of H. macgregori . 

 The Austrian author's figure shows thi« beyond question, 

 while the differences he notes between his specimen and 

 Boulenger's* Solomon Island examples are precisely the 

 characters in which H. macgregori differs from H. thesau- 

 rensis. Therefore, the distribution of each must be amended. 

 H. macgregori is confined to British and German Papua, 

 and H. thesaurensis to the Solomon Islands. 



The specimen figured on Plate II, fig. 3, is not quite 

 the largest specimen, but is, perhaps, the most typical : 

 that figured in the text is only a half -grown example. 

 I cannot account for the discrepancies between Mr. Ogilby's 

 description and mj^ own.
