There are no teeth in the upper jaw, but in the under there are a confiderable 
number j they are long, tall, rounded, and a little bent inwards; they are thicker at 
the roots than thofe of the preceding fpecies, and are lefs bent or falcated, though 
their extremities turn inwards j thefe alfo are not conic, as in the others, but plane : 
there are three fins on this fifh; that on the back is the moll lingular ; it is large and very 
tall, fimple, and eredt, and looks like the mizzen-maft of a fhip : the tail alfo is very 
large and broad. 
This fpecies has been thrown on fhores about the northermoft part of Scotland ; we 
owe our knowledge of it to the fame author who defcribed firft the other. He calls 
it Balsena macrocephala tripinnis quas in mandibula inferiore dentes habet minus in¬ 
dexes et in planum definentes j Ray alfo has continued this name. 
DELPHINUS. 
/"Tp\ H E Delphinus has teeth in both the jaws, the fiftula, or opening for the dis¬ 
charge of water is in the middle of the head, and the back is pinnated or 
finned.

pefs. 
This is a very large and not a very beautiful fifh : the bead is large, and the body 
is very thick toward the head, but it grows gradually fmaller to the tail 5 the whole 
thence has fomewhat of a conic form : the back is broad, and the diameter in the 
largeft part is more than equal to half the length of the fifh : the roftrum is protend¬ 
ed ; the head is not very large; the opening of the mouth is wide, and there are teeth 
in confiderable numbers in both jaws; there are about forty-eight in the full-grown 
fifh in each jaw, and they are acute and fomewhat moveable : the fiftula or aperture 
for the difcharge of water is nearly in the middle of the head, and befide this there 
are fix other fmaller foramina about the roftrum : the apertures for the ears are fo 
fmall, that they are fcarce perceptible: the body is, in general, of a rounded figure, 
but, as it approaches the tail, it becomes a little comprefled : the tail is large; it is 
placed horizontally, and is a little divided or forked : the ftomach is triple: the intef- 
tines are extreamly long ; the kidnies are compofed of a great number of lobules, and 
the ribs are thirteen on each fide. 
This fpecies is not unfrequent in the Northern Seas, and frequently comes a great 
way up the large rivers 5 we have it fometimes in the Thames: the writers of all times 
have been acquainted with it. Ariftotle calls it ; Gaza, Tirfio ; Pliny, Bello- 
nius, and Rondelet, Turfio; Jonfton, Charleton, Willughby, and Ray, Phocasna; 
Gefner and Aldrovand, Phocaena five Turfio j Gefner, Phocaena five Thurfio; and 
Schoneveldt, Parvus Delphinus vel Delphinus feptentrionalium aut orientalium. The 
Swedes and Danes call it Marfuin; and we, the Porpefs: this, however, is not fo de¬ 
terminate a name as it ought to be, for we call the following fpecies or proper dolphin 
alfo the Porpefs. 
Delphinus corpore oblongo fubtereti , rofro longo acuto . 
The Delphinus , with an oblongs fubcylindric body , and 
a long , acute rofrum. 
This is a confiderable longer fifh than the former, but it’s body is not thick, in pro¬ 
portion : the head is not immoderately large; the roftrum is very long and acute 5 the 
opening of the mouth is vaftly wide, reaching on each fide to the breaft: both jaws 
are furnifhed with numerous teeth, and the opening them has a very terrible appear¬ 
ance : there are two longitudinal depreftions before the eyes, and in the middle of the 
head ftands the fiftula or aperture for the difcharging water j it is double, or has two 
paftages within, but it terminates fingly: the body is of a rounded figure, and does 
not diminifh fo much in thicknefs toward the tail, as the former fpecies: the parts of 
generation in both the fexes are very vifible, and ftand at a middle diftance between 
the anus and the navel.
