Platyplacopus kuehnei, Bouleng. t.c. p. 232, pi. xlvii, fig-. 3. 



Body feebly depressed. Head nearly twice as long as broail, flat 

 above, its depth equal to the distance between the centre of the eye 

 and the tympanum, its length 3J times (male) in length to vent ; 

 snout acutely pointed, as long as postocular part of head, with sharp 

 canthus and vertical loreal region. Neck narrower than the head. 

 Pileus slightly more than twice as long as broad. Hind limb reaching 

 the axil (male) ; foot as long as the head. Tail more than twice as 

 long as head and body. 



Nostril pierced between (three or) four sliields. Rostral not 

 touching the nostril, rarely in contact with the frontonasal* ; upper 

 head-shields rather rough with faint strise and pits ; frontonasal a little 

 longer than broad ; prefrontals forming an extensive median suture ; 

 frontal with a median keel, a little shorter than its distance from the 

 end of the snout, as long as the frontoparietals, 1 J times as long as 

 broad, a little narrower behind than in front; parietals If times as 

 long as broad ; interparietal li times as long as broad, separated from 

 the smaller occipital by a short suture formed by the parietals. 

 4 supraoculars, first veiy small, second and third equal, fourth small ; 4 

 superciliaries, first and second elongate, first in contact with the second 

 supraocular and followed by a series of granules. t Two superposed 

 postnasals +; anterior loreal much shorter than second; 4 upper 

 labials § anterior to the subocular, which is a little uarroAver beneath 

 than above ; temporal scales very small, granular, keeled ; an enlarged 

 anterior upper temporal, not in contact with the fourth supraocular ; 

 a very narrow tympanic shield. 



No pterygoid teeth. 



4 pairs of chin-shields, the 3 anterior in contact in the middle. 

 28 gular scales on the median Hue, anterior granular, posterior 



* According to Vogt. 



t The series sometimes complete according to Van Denbiirgh. 

 X This i.s probably an individual abnormality in the specimen examined 1iy 

 me, as no mention is made by Van Denburgli of two postnasals.
