The triangular Of radon , with twofpines on the fore- ftHJJUiftt Jfttl)* 
head\ and two on the lower part of the belly . 
T H IS is about eight inches in length, and is moderately broad and thick, in pro¬ 
portion : the head is fmall, and the roftrum acute ; the mouth is fmall, and has 
a pair of moveable lips furrounding, but not entirely doling, it : the teeth are nu¬ 
merous and large ; the apertures of the noftrils are two on each lide, and are very con- 
fpicuous; they Hand at about the midway between the eyes and the extremity of the 
roftrum : the eyes are large, and are covered by a membrane j the body is of a tri¬ 
angulated form, and is covered with a number of very beautiful angulated bodies 
in the place of fcales; thefe are not all of exactly the fame form, but the greater num¬ 
ber of them are hexagonal; they are radiated, and make a very beautiful appearance % 
the peCtoral fins have each eleven rays; the back fin and the pinna ani have each ten 
rays j the tail is not forked, but equal at the extremity, and has from eight to ten 
long rays. 
This fpecies has not been defcribed by the generality of writers on thefe fubjeCls, 
but we have it in fome of the collections of our naturalifts, I bought a fine fpecimen 
of it among the late Duke of Richmond’s fpecimens.

pendix to Willughby, calls it Pifcis triangularis capite cornutus, cui aculeus longus ad 
caudam erigitur. 
Oftracion triangularis limbis fgurarum hexagonarum eminentibus^ aculeis

and the teeth in it difproportionately large : the eyes are large, and are covered with the
