Squalus pinna ani carens , naribus in extremo roftro . 
The Squalus , no pinna ani y and with the nojlrils 
at the extremity of the rojirum . 
This grows to about five feet in length : the head is large, and of a deprefled 
form j the roftrum is fubacute, and the nofirils are fituated alrnbft at it’s extremity, 
each having two apertures: the eyes are large, and the mouth fiands tranfverlely on 
the under part of the roftrum : the body is of an oblong and fomewhat deprefled 
form 3 the back is almoft flat, and is lefs rough than the reft of the body: the fides 
are prominent, and the belly is fomewhat flatted, and it’s fkin is extreamly rough : 
the general colour of the fifli is brown, but the belly, inftead of being paler, is of a 
deeper colour than any other part: there are two back fins, and each has a fpine at it’s 
anterior part 3 there are two belly fins moderately large, but there is no pinna ani: the 
tail is large, comprefled, and divided into two parts, of which the upper is the longer. 
This is very frequent in the Mediterranean, and is caught in different parts of the 
Ocean alfo, but more rarely. Willughby and Ray call it Galeus acanthias five fpinax 
fufcus, the brown, prickly Hound-fifh. 
Squalus pinna ani carens , ambitu corporis triangulato . 
The triangulated-bodied Squalus 3 with no pinna ani . 
This is a large fpecies: the head is large, and of a deprefled figure 3 the roftrum is 
obtufe 3 the noftrils have each a double aperture, and are fituated low 5 the eyes are 
large, and their iris is of a greyifh-white ; the pupil is fmall, oblong, and blackifti 3 the 
mouth is a tranfverfe fiflure on the under part of the head, not at the extremity of it. 
There are in the upper part three rows of ftharp teeth, but in the lower part there is 
only one row : the body is oblong, thick, and of a fomewhat triangulated form 3 the 
apertures of the gills are five on each fide, running obliquely, and placed in a line from 
the head to the pedoral fins : there are two fins on the back, and the prickle or fpine 
at the anterior one is turned fomewhat forward : the ventral fins are moderately Urge, 
and there is no pinna ani: the tail is divided into two parts, and of thefe the upper is 
much the longer. 
This fpecies is frequent in the Mediterranean, and in fome other feas: it was well 
known to the antients. fiElian, Athenasus, and Oppian call it Kevrpu ; Rondelet, 
Salvian, Gefner, and Aldrovand, Centrina5 Jonfton, Willughby, and Ray, Centri- 
ne 5 Gefner, Galeus Centrina 3 Bellonius and Gefner, in fome others parts of his 
works, Vulpecula. The Italians call it Centrine and Pefce Porco. 
Squalus pinna ani carens , ore in apice capitis . 
The Squalus , with the mouth at the extremity 
of the head. 
This grows to about fix feet in length, and is confiderably thick, in proportion 3 and, 
though it has all the other external characters of the Squali, differs greatly from them 
in the fituation of the mouth, which is not, as in them, fituated on the under part of 
the head, but at the extremity, as in the generality of other fifties: the noftrils are 
confpicuous, and have each a double aperture 3 the eyes are moderately large, and the 
apertures of the gills are five on each fide, fituated between the back part of the head 
and the pedoral fins : there are three rows of teeth in the upper part of the mouth, 
and as many in the under 3 the whole number amounts to a hundred and eight about 
the region of the eyes, as alfo near the noftrils there are feveral fpinofe tubercles, and 
on the extream verge of the pedoral fins there are alfo fome ftiort fpines, and fome 
others on the ventral fins 3 and on the middle of the back there are two back fins, 
but they ftand extreamly backward, both behind the anus : the pedoral fins are mo¬ 
derately large; the belly fins are alfo large and broad, they are placed contiguous to one 
another, and in an horizontal diredion : the tail is forked, and the upper portion is 
longer than the under. 
This fpecies is caught in our own feas, but more frequently in the Mediterranean : 
v the antients were well acquainted with it. The Greeks call it 'Pimj 5 Pliny, and the
