A number of specimens from Shanghai (U.S.N.M. Nos. 67035-38 

 and 73188) add little to our knowledge of this form. Their dorsal 

 lepidosis is normal; the male (No. 67035) has eight preanal pores in 

 a continuous row, and three well-developed basicaudal tubercles. The 

 young, No. 73188, has also three small such tubercles : in the others 

 they are represented by clusters of smaller tubercles.

This form has been separated from G. japonicus on the strength 

 of the large single tubercular scale at the base of the tail. In 13 

 topotypes recorded by Mr. Pope it was single on both sides; in the 

 fourteenth specimen it was divided on one side. 



By referring to my Herpetology of Japan, p. 168, it will be seen 

 that this feature is subject to great variation in true G. japonicus, 

 even in Japan, where specimens with large single tubercles are not 

 uncommon. However, in most of the specimens, both in Japan and 

 on the mainland, esioecially in the lowlands of the lower Yangtse 

 Basin, the number ranges from 1, 2, or 3 larger tubercles to clusters 

 of smaller tubercles, as attested by 12 specimens in the National 

 Museum, from the Kiangsu, Hupeh, and other Provinces. 



The type material of the present form comes from a plateau on 

 the boundary between Fukien and Kiangsi. The Museum of Com-
