similar light, dark-bordered stripe on front of forearm; maximum 

 size known, 23 millimeters. 



Description of holotype. — Tongue as wide as mouth-opening, broadly 

 ovate, its posterior border free and unnotched; snout very obtusely 

 pointed when viewed from above, truncate and sloping backwards 

 in profile, the upper jaw extending well beyond the lower. Nostrils 

 lateral, slightly projecting, their distance from end of snout two-thirds 

 their distance from eye. Can thus rostralis rounded but definite; loreal 

 region concave, the upper lip flaring slightly beneath it. Eye large, 

 prominent, its diameter four-fifths its distance from tip of snout; 

 interorbital diameter twice that of upper eyelid and equal to interval 

 between nostrils. Tympanum small but distinct, its greatest diameter 

 one-half that of eye, separated from eye by an interval equal to one- 

 half its own diameter. Fingers moderate in length, with small lateral 

 ridges and faint traces of a web, first and second fingers subequal, 

 fourth finger much longer than either and reaching to base of penulti- 

 mate phalanx of third, whose disk covers about one-eighth the tym- 

 panum; a small distinct oval thumb pad; a larger round palmar 

 callus; metacarpal tubercles well developed. Toes moderate, nearly 

 one-fourth webbed, third toe a little longer than fifth, reaching to center 

 of antepenultimate phalanx of fourth, the disk of which covers about 

 one-fourth the tympanum and is larger than that of third finger; a 

 small but distinct inner metatarsal tubercle and a somewhat larger, 

 rather prominent outer one: a strong tarsal ridge, ending in a diagonal 

 swelling midway to heel; a pronounced skinfold on heel and knee. 

 Body rather stout, in postaxillary region a little wider than greatest 

 width of head. When hind leg is adpressed, heel reaches to posterior 

 border of tympanum; when limbs are laid along the sides, knee and 

 elbow touch; when hind legs are bent at right angles to body, heels 

 touch. Skin of upper parts not subject to abrasion, smooth anteriorly, 

 granular above anus; a glandular swelling from above tympanum, 

 narrowing to a ridge along side, bending downwards to end in a semi- 

 circular gland just in front of groin; venter smooth ; some weak granules 

 on lower surface of femur; some very fine diagonal glandular ridges on 

 side; no skinfold across the chest; no ventral disk; no apparent 

 external vocal sacs in male. 



Dimensions. — Head and body, 23 mm.; head length, 7 mm.; head 

 width, 7.5 mm. ; femur, 9 mm. ; tibia, 9 mm. ; foot, 10 mm. ; hand, 6 mm. 



Color in alcohol. — Dorsum, including head and upper limb surfaces, 

 clove brown; a curved black bar between the eyes; a light stripe from 

 snout tip, continuing below canthus to eye, and following below the 

 narrow glandular line to groin, where it curves downward in front of 

 femur; throat and chest straw yellow with a few sepia spots below 

 chin and a narrow sepia line around lower jaw; a wide clove brown
