Head and body moderately depressed. Head rather large in males- 

 (rarely 4 times in length to vent), 1^ to If times as long as broad, its 

 depth equal to the distance between the anterior corner or the centre- 

 of the eye and the tympanum ; occipital region convex ; snout obtuse, 

 as long as postocular part of head ; cheeks not much swollen in the 

 male; length of pileus about twice its width. Neck sometimes as 

 broad as head, usually narrower. Hind limb reaching the shoulder

 shorter than its distance from the end of the snout, IJ to If times 

 as long as broad, as broad behind as the principal supraoculars,, 

 sometimes in contact withf or narrowly separated from the first 

 supraocular ; parietals H to If times as long as broad, usually not in 

 contact with the upper postocular,J the outer border straight and 

 oblique or more or less emarginate in front for the accommodation of 

 the upper temporal ; occipital usually shorter and broader than the 

 interparietal, sometimes as long or as broad. The two major supra- 

 oculars, of which the first is usually the longer, separated from the- 

 superciliaries by a complete series of granules ; the fourth supraocular
