Vor. III] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 207 
Gekko swinhonis (Giinther) 
We have five specimens collected by Dr. Thompson at 
Chefoo, China, August 19 to 29, 1906. These are entirely 
without webs between the digits, and their enlarged dorsal 
tubercles are very few, and the tubercles near the ear many, 
as compared with specimens of Gekko japonicus from Shang- 
hai, Formosa, and the Loo Choo Islands. There appears to 
be no constant difference in the chin-shields. 
Hemidactylus frenatus Duméril & Bibron 
The’ collection contains twenty-three specimens of this 
gecko from Formosa, where they were collected at Tainan, 
Kohekiryo, Kanshirei, Takao, Anping, Polisia, Koshun, and 
Ako. From the Loo Choo Islands we have received six from 
Okinawa, three from Miyako and seventy-four from Ishigaki. 
It therefore appears that this species is much more common 
than H. bowringii. We have also twelve specimens from the 
Pescadores, where they were found under stones on barren 
hill-sides. 
Careful comparison has failed to bring to light any dif- 
ferences in the specimens from these various localities. 
Hemidactylus bowringii (Gray) 
We have received one male (21854) from Miyako, one 
male (21856) and one female (21855) from Ishigaki, and four 
males from the following localities in Formosa: 18066 Kan- 
shirei, 18078 Taipeh, 18079 Taihoku, and 18080 Nanto. 
There seem to be no important differences between these 
specimens. They may be readily distinguished from H. fre- 
natus by the nearly uniform dorsal granulation, longer ter- 
minal portion of the inner digit, and the median interruption 
of the series of pores in the males. 
Hemidactylus marmoratus Hallowell 
We have received no specimen which agrees with Hallo- 
well’s description of H. marmoratus although we have one 
hundred and fifty specimens of various species of Gekkonidae
