They have characteristic tufts of "horns" above each eye.〔 Two subspecies are currently recognized, including the nominate subspecies described here. ==Description== Small and stout, they grow to an average total length (body + tail) of 30–50 cm (about 12-20 inches). The maximum recorded total length is for a captive specimen.〔 There are two to five raised horn-like scales above each eye.〔Boulenger GA. 1896.

(''Bitis cornuta'', pp. 497-498.)〕 Dorsally, it has a grey to reddish brown ground colour, overlaid with four longitudinal series of large dark brown blotches, which are squarish or parallelogram-like in shape, and edged with white. Ventrally, it is whitish or tan, either uniform or speckled with dark brown. On the dorsal surface of the head are dark symmetrical markings which may form an arrowhead.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bitis cornuta」の詳細全文を読む スポンサード リンク
