We have it in our own Teas, but not common ; that which was fhewn in London 
was caught near Dover. It had feized upon the body of a drowned woman, and could 
not difengage it’s jaws, but, on taking the body up, was brought on fhore with it. 
, This has been known at all times to the naturalifts. Ariftotle calls it *'AA ta? 
pa-rcn/; and, in other places, Bdrpotx<& dxiFg • dElian calls it BAp^©-* dxisvg • Athenseus 
and Oppian,^ limply, BarOvid, Pliny, Cicero, and the reft of the old Latin 
writers call it Rana and Rana marina; Bellonius, Salvian, and moft of the moderns, 
Rana pifcatrix ; Gefner calls it Rana pifcatrix live marina; and Aldrovand, Rana pif- 
catrix vulgaris. We call it the Toad-fifh, the Frog-fifh, and the Sea-devil. 
There is but one other known fpecies of this lingular genus, that is, the American 
frog-lifh,^with a lingle horn on its head. Marcgrave and others after him have 
called this, by it’s Brafilian name, Guacucuja; Linnaeus calls it, Lophius fronte 
unicorni.

Fifties^ with the tail placed perpendicularly , and with the rays of the

PETROMYZON. 
HP H E foramina or apertures of the gills, or of the lungs, are in the Petromyzon 
JL . feven on each fide, lituated longitudinally; and there is, belide thefe, one in 
the middle of the head, between the eyes: the body is long and llender, and nearly 
cylindric, and is fmooth; there are only two fins, and thofe are both on the back of 
the filh.

This grows to about a foot long, but what are ufually caught are under that ftand- 
ard : the body is fender, almoft cylindric in figure, but a little comprefled, efpecially 
toward the tail; it is all over perfectly fmooth, or without the leaft appearance of 
icales, and is covered with a lubricous, tough matter in the manner of the eel • the 
whole back and the belly are convex : the colour on the back is a fimple bluifh-green, 
without any variegations; on the belly it is white and filvery: the head is but very 
little diftinguifhed from the bocly ; it is only fomewhat fmaller and flenderer; it’s 
inape is rounded, and there are no diftinguifhable jaws: the mouth is not at the ex¬ 
tremity of the roftrum, but on it’s under part, and is round, large, and may be ren¬ 
dered wider or narrower by the creature’s power of fucking, and drawing it more or 
Ids in : there is a row of extreamly minute teeth in the verge or rim of the mouth; 
and in the upper part of it, within this limb, there are about fix other feries 
of teeth of the fame fize and form : at the fides of the mouth there are alio three 
bones or teeth, of which the upper one is bifid, the fecond is fometimes trifid, fame- 
times only bifid alfo, and the loweft is always bifid ; in the lower part, juft at the en¬ 
trance of the mouth, there is alio a bone of an oblong figure, and ferrated, fo as to re- 
prefent the divifions of feven teeth; and above this there is a femilunarand confidera- 
bly tnick bone : and, finally, deeper in the mouth there is another bone, armed with 
feven teeth, which is connected fo loofely, that it may be eafily pulled out; and at 
the lo wer part of the fauces there is a bifoliate cartilaginous officle of a very odd 
figure : fuch is the fingular armature of the mouth of this little fifh.
