 loreal region, sharp canthus rostralis, and convex upper labials. 

 Lower eyelid with a very large transparent disk. Nostril on the 

 canthus rostralis, just above the suture between the rostral and 

 the first labial; a postnasal; anterior loreal largely in contact 

 with the first labial ; suprauasals in contact behind the rostral ; 

 frontonasal as. long as broad, or a little broader than long, usually 

 in contact with the frontal ; latter as long as the frontoparietals 

 and interparietal together, in contact with the second and third 

 (rarely also the first) supraoculars ; four supraoculars, second largest ; 

 five supraciliaries, second largest ; frontoparietals distinct, as large 

 as or a little smaller than the interparietal : parietals entii'ely sepa- 

 rated or forming a very short suture behind the interparietal; a 

 pair of nuchals : subocular much narrowed inferiorly, bordering the 

 lip between the fourth and fifth, or fifth and sixth upper labials.
