supranasals; a small roundish scale on either side of this and 

 directly behind the supranasals, touching the superior postnasal ; 

 11 upper labials; 10 lower labials; mental much smaller than 

 the rostral or any of the five first lower labials, followed by two 

 postmental scales ; latter elongate, widest in the middle ; on each 

 side of the postmental a row of scales gradually diminishing 

 in size bordering the labials ; scales from the supraocular regions 

 on the head twice as large as those on occiput ; latter area with 

 scattered small tubercles; a group of enlarged scales directly in 

 front of the eye, back with uniform granular scales intermixed 

 with flat roundish tubercles, 6 or 7 irregular rows on each side ; 

 scales on belly much larger than dorsal scales, or scales on the 

 neck; on each side of the head below the auricular opening is a 

 dermal flap, widest in front of the auricular opening and con- 

 tinues from near the angle of the mouth to some distance on the 

 neck; a similar flap on the foreleg entirely bordering the limb; 

 the dermal flap on the hind leg is wanting from the groin to the 

 knee ; on each side of the body a wide dermal flap or parachute, 

 extending from the fore limb, where it joins the flap of the fore 

 limb, and continuing to the groin; tail with a lateral series of 

 small rounded lobes decreasing in size toward the tip and directed 

 backward "saw-tooth" fashion ; tail with a flap on the tip, which 

 is scarcely wider than the nearest lobes; each segment of tail 

 with a number of enlarged scales; on the first half these are 

 from 8 to 6 on each segment, on the last half the number is 

 reduced, digits not webbed to the tips; distal phalanx on inner 

 finger and toe replaced by a flattened scale. A series of 10 dif- 

 ferentiated preanal scales arranged in a curved line; widely 

 separated from these is a series of differentiated femoral scales 

 13 to 14 in number; a large scale on each side behind anus. 



Color in life. — A soft olive gray above with touches of bluish 

 and brown; body transversed with several wavy lines of dark 

 brown. Head more or less flecked with brown; a broad brown 

 band from eye to shoulder; legs indistincly barred with reddish 

 brown bands ; below cream with large indistinct spots under the 

 tail. 



Measurements. — Total length, 189 millimeters ; snout to vent, 

 92 ; length of head, 24 ; height of head, 10 ; width of head, 21 ; 

 foreleg, 30; hind leg, 43; width of lateral flap, 8.5; length of 

 femur, 15 ; greatest body width, 20. 



Remarks. — This species seems to be intermediate between the' 

 two other known species of this genus. From Ptychozoon kuhli 

 it differs in the absence of the wide flap at the extremity of
