between fingers I, II and III, faintly between fingers III, [V and V; margins of webs attaching to 
proximal one third of toes; hindlimb much developed, its length 95% of axilla to groin length; 
underneath dilated portions of toes covered with lamellae, eight on toe I, seven or eight on toe II, 
eight on toe III, nine on toe IV, and nine on toe V; rudimentary webs evident between toes I, II, III 
and IV; a single large spur on each side of base of tail; tail regenerated, very short. 
Dorsal ground color in preservative grayish tan; a brown bar running along lower margin of eye, 
almost reaching to ear opening posteriorly; dorsal surfaces of neck and body with nine transverse 
brown bands; dorsal surfaces of limbs also with transverse brown bands; venter of body pale red- 
dish yellow. 
This new species greatly resembles G. hokouensis. However, the latter has supranasals sep- 
arated from each other, and conical dorsal tubercles. Moreover, the head and body length of G. 
hokouensis is shorter than 70 mm. 
G. liboensis is rarely observed at Chengguan, Libo Prefecture.

Jiangxi Province) 
Pope (1928) regarded this form as a subspecies of G. japonicus, and stated that G. j. hokouensis 
differs from the nominal subspecies only in the number of cloacal spurs; he noted that the former 
has a single spur on each side of the base of tail, whereas the latter has two or three spurs. While 
investigating a large series of specimens, we found that hokouensis has a relatively large spur, 
measuring about 2.2-3.1 mm for the male and 1.3-2.0 mm for the female in maximum diameter. 
Although the spur is more or less grooved and incompletely divided in a few males and most 
females, the outline of the single spur remains apparent in all animals (Plate II: 4-9). On the other 
hand, japonicus possesses two or three smaller spurs below three larger spurs. The size of each 
spur is relatively small, and the maximum diameter of the largest spur measured 1.2-1.5 mm in the 
male and 0.6-1.0 mm in the female (Plate II:10-11). Differences are recognizable between hok- 
ouensis and japonicus also in the condition of dorsal tubercles as follows. In hokouensis, tubercles 
are absent on the four limbs, and relatively few around the middle of the body. On the other hand, 
in japonicus, the dorsal surface of the forearm and shank is covered with tubercles, and the tuber- 
cles around the middle of the body are in relatively high density (Plate II:2-3, Table 3).
