Head aud body feebly depressed. Head 1^ to 1| times as loug as 

 broad, its depth equal to the distance between the anterior corner of 

 the eye and the tympanum, its length 4 to 4^ times in length to vent ; 

 snout obtusely pointed, as long as postocular part of head, with 

 obtuse canthus. Pileus twice as long as broad. Neck as broad as 

 the head or a little narrower. Hind limb reaching the shoulder or 

 between the shoulder aud the ear in males, the axil or the shoulder in 

 females ; foot 1^ to If times as loug as hand ; toes slender, feebly 

 compressed. Tail 2 to 2^ times as long as head and body. 



Nostril pierced between 3 shields ; nasals forming a suture behind 

 the rostral, the suture ^ to | the length of the frontonasal, which is 

 much broader than long and broader than the iuternarial space ; jire- 

 frontals forming a short median suture ; frontal as loug as its distance 

 from the eud of the suout. 1^ to If times as long as broad, angular in 

 front, much narrower behiud, not or but very feebly grooved in front ; 

 parietals IJ to 1^ times as loug as broad, usually meeting on the 

 median line, the interparietal being small and separated from the 

 occipital, or often altogether absent * ; occipital small,t rarely in 

 contact with the interparietal. + Two large subequal supraoculars, 

 preceded aud followed by a small one (first aud fourth) often broken 

 up into two or more small shields or granules, the first in contact 

 with the frontal ; 6 or 7 superciliaries, separated from the supraoculars 

 by a series of granules. Lower eyelid opaque or somewhat trauslucid, 

 with feebly enlarged scales in the middle, some of which are deeper 

 than the others. Eostral not entering the nostril ; a single postnasal ; 

 anterior loreal shorter than the second § ; 4, rarely 5, upper labials 

 anterior to the subocular, which is usually narrower beneath than 



* Absent in the type specimen and in most of the 59 specimens from Ghinda 

 examined by me. I was wrong in thinking the absence of this shield in the 

 type specimen to be an individual anomaly. 



t Divided into 2 in the type specimen. 



t In 2 female specimens from Rugdeia Sogheira in the Genoa Museum. 



§ Absent in the tyi^e specimen.
