_Male (KU 40118 from 5 mi. E Seoul)._--Snout-vent length, 65; no vocal sacs or slits; dorsal and inner surfaces of first and second fingers, and inner surface of third finger black; canthus rostralis indistinct (a well-defined ridge on right side); nostrils closer to tip of snout than to eye, their distance from each other slightly less than interorbital width; interorbital width (6.2) greater than width of eyelid (4.7); tympanum distinct, circular, its diameter (3.0) less than length of eye (6.5), and approximately twice distance (1.6) of tympanum from eye; no cranial crests; parotoid gland elongate, approximately twice as long as broad (12.5 × 5.0), narrowly separated from posterior edge of eyelid; head elongate (width at posterior edge of tympanum, 23.6); length from posterior edge of tympanum to tip of upper jaw, 18.9; first finger slightly longer than second, fourth finger about two-thirds as long as third; most subarticular tubercles divided; outer palmar tubercle larger than inner; heels not touching when folded legs placed at right angles to longitudinal axis of body; tibiotarsal articulation just reaching eye when leg laid forward; tarsometatarsal articulation not reaching beyond snout; foot large (tibiotarsal articulation to tip of fourth toe approximately 46.0); fourth toe approximately half webbed, other toes more than half webbed; edges of webs somewhat crenulate; some subarticular tubercles divided; length of inner metatarsal tubercle (4.5) more than half length of first toe (7.0); inner metatarsal tubercle larger than outer, both darkened; tarsal fold extending from inner metatarsal tubercle for approximately two-thirds length of tarsus; tips of toes (not fingers) darkened; dorsal surface of back and proximal part of hind legs coarsely granular, of rounded, pavement-type tubercles lacking sharp tips; small group of warts near angle of jaw below parotoids; dorsal pattern contrasting and irregular (especially on limbs), of dark brown and pale gray; conspicuous black mark (interrupted) on lateral surface of parotoid having two, well-defined spurs that project posteroventrally; undersurface granular, lacking markings except for two indistinctly-margined dark spots on chest, and black spot on left leg. _Remarks._--This nocturnal, introduced species (Okada, 1931:47) is presumably widespread in Korea and seemingly prefers lowland habitats. Individuals were taken in sparse vegetation on a sand flat near the Han River, at the edge of a rice field in a light rain, along a road at night, and in millet fields adjacent to the Han River, which was flooding at that time (July 9).
