4 PROCEEDINGS OP THE NATIONAL MUSEUM vol. 82 



parative Zoology has a large series of specimens from Tunglu, about 

 165 miles to the northeast in the neighboring Province of Chekiang, 

 collected by J. T. Wright. Thanks to the kindness of Dr. Thomas 

 Barbour, 10 of these are in the National Museum (Nos. 78193-202), 

 and in every one of them the tubercle is single and large, somewhat 

 of the shape of the " shovel " on the metatarsal tubercle of certain 

 toads. In some of the specimens there is evidence of its origin in 

 a consolidation of three smaller tubercles.^ These specimens from 

 Chekiang are otherwise identical with the average Yangtse basin 

 specimens, except that perhaps more specimens of the former show 

 a tendency toward the dorsal tubercles being less numerous on the 

 middle of the back than in the former. Similar specimens occur also 

 in our series from Japan and Korea. As a consequence I am unable 

 to distinguish these Kiangsi-Chekiang specimens with a single 

 basicaudal tubercle from a number of Japanese and Chinese speci- 

 mens of typical G. japonicus. Nevertheless, in view of the large 

 number of individuals in the region where the three Provinces of 

 Kiangsi, Fukien, and Chekiang meet, displajdng this character, I 

 consider it expedient to recognize this form trinominally at least 

 until further researches shall have evaluated the importance of this 

 character. I am the more inclined toward this procedure by a 

 ^consideration of the fact that in all our specimens of G. suhpalmatus 

 the tubercle in question is large and single. 



Owing to the comparative nearness of Chusan, the type locality 

 of Cantor's Hemidactylus nanus (Ann. Nat. Hist., vol. 9, Aug., 1842, 

 p. 482), I requested Mr. Parker to examine the type in the British 

 Museum with regard to the basicaudal tubercles, and he kindly in- 

 forms me that there are three on each side of the base of the tail. 

 The name therefore seems to be an unconditional synonym of G. 

 japonicus^ as represented by the Shanghai specimens, and does not 

 interfere with the nomenclature of the form here considered.

^ Dr. Thomas Barbour has kindly examined the remaining series of 25 specimens in the 

 Museum of Comparative Zoology. He summarizes the result as follows : " I would define 

 the Tunglu lot as characterized by having, in the adult males, invariably a single, elongate, 

 shovel-shaped tubercle derived from the coalescence of two rudiments which occasionally 

 persist as independent papillae in young specimens and of these larger in females than 

 in males."
