ture is fuperadded the peculiar fiercenefs and forbid- 

 ding torvity with which nature has marked its counte- 

 nance; diftinguifhed by the very uncommon appear- 

 ance of two large and fharp-pointed horns, lituated, 

 (not as in the Cerattes, above the eyes,) but on the 

 top of the nofe, or anterior part of the upper jaw. 

 They ftand nearly upright, but incline flightly back- 

 wards sllA and a little outwards on each lide, and are 

 of a fubfbance not abfoluteiy horny, but in fome degree 

 flexible. Their fhape is fomewhat triangular or three- 

 fided. They are about half an inch in length, and at 

 the fore-part of the bafe of each {lands an upright 

 ftrong fcale, cf nearly the fame fhape with the horn it- 

 felf, and thus giving the appearance of a much fmaller 

 pair of horns. The mouth is furnilhed with extremely 

 large and long fangs or tubular teeth, fituated as in 

 other poifonous ferpents, and capable of inflicting the 

 moft fevere wounds: two of thefe fangs appear on 

 each fide of the mouth, of which the hinder pair are 

 fmaller than the others. The length of this animal is 1 

 about thirty-five inches. Its colour is a yellowifh olive- 

 brown, very thickly fprinkled all over with minute 

 blackifh fpecks. Along the whole length of the back 

 is placed, at confiderable diftances, a feries of yellowifti- 

 brown fpots or marks, each of which is imbedded in a 

 patch of black ; and on each fide the body, from head 

 to tail, runs an acutely flexuous or zig-zag line or nar- 

 row band, of an ochre-colour. This band is bounded 

 beneath by a much deeper or blacker made than on 

 the reft of the body. The belly -is of a dull ochre- 

 colour or cinereous yellow, freckled with fpots and 



markings
