Hyla chinensis Giinther 
Originally described from specimens from China, this was 
one of the species obtained by Swinhoe in Formosa. It has 
been recorded also from Taiwan, Formosa. 
We have received twelve adult specimens from Formosa. 
In all, the heels overlap about the width of the tarsus. When 
carried forward, the heel reaches the anterior edge of the eye 
in five, the middle of the orbit in five, and the posterior edge 
in two. One specimen (No. 20075) twenty-six millimeters 
long from snout to vent, has no vomerine teeth. Two have 
only the left patch of vomerines. There is considerable varia- 
tion in the number, shape, and distribution of the black mark- 
ings on the legs and sides of body. One large specimen has 
no black markings. On the body there may be only one spot, a 
series of spots, or a continuous narrow line. On the legs the 
markings may be confined to the thighs, or may extend down 
to the feet; may be round, or may form longitudinal streaks. 
The brown streak in front and behind the eye seems to be con- 
stantly present. The vomerine teeth are a little farther back 
than in Hyla arborea japonica from Japan, but not farther 
than in the Loo Choo species. There seems to be no appre- 
ciable difference in the extent of the web. 
Our specimens were collected at Kosempo, Keelung, Tai- 
hoku. 
Hyla hallowelli Van Denburgh 
Diagnosis.—Similar to Hyla chinensis, but never with 
black spots on legs and sides of body, and with only a trace of 
a dark streak on side of face; heels overlapping, tibio-tarsal 
articulation reaching anterior border of eye or beyond; tibia 
seldom less than half the length of head and body; no dark 
streak behind eye; green extending beyond wrist and ankle. 
Type.—Adult male. California Academy of Sciences No. 
23806. Kikaiga shima, Loo Choo Islands, Japan, April 30, 1910. 
Description of the type-—Vomerine teeth in two small central groups 
between posterior edges of choanae. Tongue rounded, slightly indented, 
and free behind. Canthus rostralis distinct; loreal region slightly oblique 
and concave. Interorbital space much broader than the upper eyelid. Tym- 
panum distinct, small, about half the diameter of eye. Fingers webbed at 
b:se. Toes webbed as in H. chinensis, Heels overlap about the width of
