Of Fijhes, 
Part I. 
is extreme (mail, fcarce ? of an inch over. His Teeth con- 
tiguous, like (mall Needles. 
On his upper Jaw grow four little Prickles on each fide. 
On each fide his nether,two great Spikes or Spurs, hard,and 
very iharp, about an inch long, pointing obliquely down- 
ward, and bended a little like a Cocks Spur. From the Root 
of thefe feveral little fhort Prickles run in a ftrait Row to the 
Eyes. 
The Gills behind make a ftrait Line, and an Angle, from 
whence they are produced forward. The Fins feven. The 
Gill-Fins hang under the Spurs, an inch and ? long near 
an inch broad. The Breaft-Fins alfo an inch and s long, 
V broad. The Back-Fin from the top of his Head, the Belly- 
Fin from his Anus are carry 'd to the Tail-Fin, fo as to ftand 
betwixt two parallel lines, making the filh almoft fquare 5 
from whence I have Nam'd it. They are both fetched 
out beyond their roots with two (harp Angles. The Tail- 
Fin an inch and ? long, and higher, with its utmoft edge 
Convex. 
The Spur above defcrib'd, is a dangerous, and as it feems, 
a malicious Weapon ^ wherewith the fifh ftrikes fide-ways, 
and as it were under-hand,not fuffering,in its doged humor, 
any other fifh to confort with it. 
The SWALLOW-FISH. So called from the length of 
his Gill-Fins, which reach to the end of his Tail, like a 
pair of very long Wings. By fome, the Flying- Herring, 
from a likenefs in the fhape of their Body. Perhaps Ronde- 
letiuss Mugilis Alatus. But by Salvian called Hirundo, by 
whom it is well defcribed. (a) That Line (faith he) which 
• in other fifties goes either from the Head or Branchiae by 
the fides to the Tail 5 here runs from the Belly-Fins along 
the Belly to the Tail. John/ton alfo defcribes it out of 
Aldrovandus, but omits the juft number of feven Fins. In 
the figure alfo which he gives, the Belly-Fins are wanting. 
And the Orbits of the Eyes, which are extraordinary great, 
he reprefenteth little. 
His Gill-Fins he ufeth as Wings, wherewith he flyeth, 
for efcape, above the water, when purfu'd by another fifti 5 
efpecially, as Pifo faith, by the Dolphin. But as they fly 
( as the fame Author) they often become a prey to Water- 
Fowl. Hundreds of them are fometimes feen above the 
Water
