Vou. II] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 193 
Nineteen specimens have a distinct mid-dorsal line. One 
(No. 22832) shows a mere indication of this line. Five are 
entirely without this light line. 
Many of the specimens have the ends of the toes so much 
dilated that they might be said to bear pads. 
The largest individuals have a length from snout to vent 
of 44 mm. 
Rana ijimae Stejneger 
This frog was described by Stejneger in 1901 from a 
single specimen preserved in the Science College, Tokyo, said 
to have been collected at Tanabinura, Okinawa shima. Care- 
ful collecting on Okinawa failed to bring to light any addi- 
tional specimens, but on Ishigaki some ten specimens were se- 
cured which agree very well with Stejneger’s type. For pur- 
poses of comparison I give the following description of the 
Ishigaki specimens: 
Description—Vomerine teeth in two oblique series, extending poster- 
iorly from a line connecting the choanae, about equidistant from the latter 
and from each other; tongue without free conical papillae; snout some- 
what projecting, nostrils much nearer to tip of snout than to eyes, and 
nearly over tip of lower jaw; interorbital space slightly narrower than 
upper eyelid; canthus rostralis well-marked; lores concave; tympanum 
one-half diameter of the eye; fingers free, first extending slightly beyond 
second, disks distinct, small, largest on third and fourth fingers, less than 
half diameter of tympanum; toes almost fully, or extensively, webbed ; one 
or one and one-half terminal digits of fourth toe free, excision sometimes 
reaching to terminal third of basal phalanx of fourth toe; disks well-devel- 
oped, a little less than half diameter of tympanum, about equal to or a 
little larger than those of fingers; subarticular tubercles very prominent; 
inner metatarsal tubercle oval, fairly well-developed, contained about two 
and one-half times in the distance from its distal border to the end of first 
toe; no outer metatarsal tubercle, except a mere thickening of skin in one 
specimen; no outer dermal fringe on fifth toe; no tarsal fold; tibio-tarsal 
articulation reaches between eye and nostril when the hind leg is carried 
forward, and overlaps about as much as the distance between eye and nos- 
tril; tibia equals or exceeds one-half length of head and body; skin of back 
usually smooth, occasionally with a few scattered tubercles; sides with 
numerous large tubercles interspersed with small ones; lores smooth or 
with asperities which sometimes are white tipped; similar asperities numer- 
ous on temporal regions and forming a ring about tympanum “like a string 
of pearls’; from two to four large glandular warts behind corner of 
mouth; dorso-lateral fold distinct, narrow or moderately broad, often not 
entirely continuous; under surfaces smooth except sometimes posteriorly 
and on thighs, where in many specimens they are granular. 
The color in alcohol varies from dark slaty brown through chocolate 
brown, olive brown, and grayish cinnamon to a greenish or brownish gray.
