cure 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, fituated, 
(not as in the Ceraftes, above the eyes,) but on the 
top of the nofe, or anterior part of the upper jaw. 
They ftand neaily upright, but incline flightly back¬ 
wards and and a little outwards on each fide, and are 
of a fubftance not abfolutely horny, but in fome degree 
flexible. Their fir ape 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, of nearly the fame fiiape with the horn it- 
felf, and thus giving the appearance of a much fmaller 
pair of horns. The mouth is furnii'hed with extremely 
large and long fangs or tubular teeth, fituated as in 
other poifonous ferpents, and capable of infiidling 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 
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 yellowifh- 
brown fpots or marks, each of which is imbedded in a 
patch of blackand on each fide the body, from head 
to tail, runs an acutely fiexuous or zig-zag line or nar¬ 
row band, of an ochre-colour. This band is bounded 
beneath by a much deeper or blacker {hade than on 
the reft of the body. The belly is of a dull ochre- 
colour or cinereous yellow, freckled with fpots and 
markings
