interval equal to their distance from eye. Canthus rostralis scarcely 

 evident, loreal region slightly concave and nearly horizontal because 

 of the unusual flatness of the snout. Eye large, prominent, looking 

 more forwards than sideways because of its position partly on the 

 front instead of entirely on the side of the head, diameter of eye 

 slightly less than its distance from tip of snout; pupil of eye small, 

 oval in shape, transverse; inner eyeballs very prominent when mouth 

 is opened; interorbital region depressed but flat, its diameter 1% 

 times that of the rather narrow upper eyelid, wider than the interval 

 between the nostrils. Tympanum entirely hidden. Fingers short, 

 thick, unwebbed, without dermal fringes, fourth much longer than 

 second and reaching to base of disk of third; first finger extremely 

 short and greatly thickened, its inner surface covered with a dozen 

 heavy black spines set in a round mass confluent with the elongated

swelling of the inner metacarpal tubercle; tips of fingers and toes 

 enlarged into regular round disks a little wider than the preceding 

 phalanx, without any trace of a median groove above or below; 

 forearm and upper arm extremely well developed but short; toes 

 short and thick, unwebbed, their disks distinctly larger than those of 

 fingers, third toe longer than fifth and reaching nearly to disk of fourth; 

 subarticular tubercles on fingers and toes reduced to indistinct rounded 

 swellings ; the outer metacarpal tubercle round and low, distinguish- 

 able mainly by position; inner metatarsal tubercle represented only by 

 an oval swelling; outer metatarsal tubercle round, small but slightly 

 more distinct; tarsus entirely smooth, without glandular lines; no 

 dermal appendage on heel. Body heavily built, in postaxillary region 

 equal to greatest width of head; when hind leg is adpressed, heel reaches 

 no farther than tympanic area; when limbs are laid along the sides, 

 knee and elbow just touch; when hind legs are bent at right angles to 

 body, heels touch. Skin everywhere coarsely granular and, under
