ART. 25 CHINESE AMPHIBIANS AND REPTILES STEJNEGER 41 



Ph. tuherculata. Up to the present time this is the only specimen 

 known in any museum. It is, therefore, a great surprise to find an- 

 other specimen, evidently closely allied, in the Graham collection 

 from Suifu. From Hubrecht's rather brief description, slightly 

 altered and added to by Dr. Nelly de Kooij,^^ it is not easy to point 

 out any radical difference between the two species, but with the 

 aid of the figures given of Ph. tuherculata it seems certain that the 

 Chinese species differs from the Sumatran one in lacking the ante- 

 rior superciliary "horns," in much larger and more numerous en- 

 larged scales and tubercles on the flanks, and fewer supralabials. 

 In the diagnosis of the genus the body is said to be covered with 

 small smooth scales. In Ph. grahami all are keeled. The descrip- 

 tions of Ph. tuherculata do not mention any nuchal median crest 

 of enlarged tubercles, nor is one shown on the first figure given of 

 the species,^* but the figure given by Miss de Rooij ^^ seems to indi- 

 cate that one is present. On the whole, the Graham specimen appears 

 to be much more tuberculated and spiny than the one from Sumatra. 

 In the latter the larger tubercles and scales are described as "mul- 

 ticarinate", by which I suppose the subsidiary wrinkles and ridges 

 are meant which appear when the central keel is transformed into 

 a more or less perfect conical tubercle. All the scales of Ph. grahami 

 are unicarinate, except those on the underside of the digits which 

 are distinctly pluricarinate. 



This genus seems to be rather cosely related to Japalura^ the chief 

 difference being the presence of a dorsal crest in the latter. The 

 finding of a Phoxophrys in China therefore is perhaps not so re- 

 markable, indicating as it does, that the two genera have a some- 

 what similar geographic distribution.
