18 MAMMALIA. FERA. Thichechus. 
22. P. barhata. Great Seal. — Length about 12 feet; fur 
consisting of thin broAvn hairs. 
Haaf-fish, Bull-fish, Pen. Brit. Zool. 1. p. 13G. — On the shores of the 
Hebrides and northern islands. 
The history of this species as a British subject is very imperfect. Pen- 
nant did not meet with it during his voyage. The Ilev. Donald Maclean, in 
his account of the Parish of Small Isles, Stat. Ac. vol. xv'ii. p. 275., mentions 
the great seal as a distinct species, and states, that, while the common kind 
bring forth their young in the middle of summer, this species does so about 
the middle of harvest. Dr Edmonston, in his “ View of the Zetland Is- 
lands,” ii. p. 294., says, “ That the head is longer in proportion to the body 
than in the common seal; that they live in pairs only, and in exposed situa- 
tions.” In the article Greenland, in the Edin. Encyc., by Sir Charles Giesecke, 
it is stated, that the flesh of this species is white and very good. The “ Great 
Seal” of the British Museum (Phil. Trans, xlii. p. 383. tab. i.), seems to be an 
aged individual of the common species. In the Appendix, No. 4., to “ Boss’s 
Voyage of Discovery to Baffin’s Bay,” there is a description of this species, 
which we shall here insert, as furnishing a standard of comparison in the exa- 
mination of our native kind. 
“ Its length, from the tip of the nose to the extremity of the tail, was 
8 feet ; its circumference, behind the fore-flippers, 5 feet 7 inches ; weight, 
830 jmunds. Fore-fiippers measured in length 1 1 inches, in breadth 6 in- 
ches. Plind-flippers, in length 10 inches, in breadth 2 feet; when expanded. 
The claws of the former were black, horny, and curved ; those of the lat- 
ter were long and straight. Fingers- five, middle ones longest in fore-flip- 
pers. The body covered with thick, coarse, short, dark grey hair. The eyes 
about the size of an ox’s, furnished with a nictitant membrane, irides dark 
hazel; the pupil elliptic, perpendicular. No external ears; the auricular 
apertures placed about 2 inches behind the eyes. The upper lip broad, round- 
ed, fleshy, divided into two lobes by a deep sulcus, division, vdiich is black and 
naked ; each lobe is provided with eight rows of strong white bristles, semi- 
pellucid, and curled at the ends ; the lower less thin and pointed. Tongue 
thick, pointed and cleft ; upper surface papillous. Teeth, upper front six, 
truncate, small ; tusks solitary, truncate ; grinders three, the anterior one 
solitary ; lower front four, imperfectly developed ; tusks small and obtuse ; 
grinders seven, the two posterior imperfectly lobed, the rest being small long 
tuberosities, scarcely produced through the gum. The heart about the bulk 
of that of the ox, its texture strong ; the foramen ovale obliterated, (a point 
on which there is yet some discord among comparative anatomists). The 
aorta 3 inches in diameter, its coats 2-| lines in thickness ; the caliber of the 
pulmonary artery nearly the same ; the thickness of its coats 1 line. Kidneys 
elliptic, lobes 150 to 160. Stomach filled with a greenish dark fluid; its in- 
ner coat lined with ascarides an inch and a half long ; they hold on with great 
tenacity, rendering it difficult to detach them; the small intestines were in- 
habited thickly with teniae, from 1 to 5 feet in length. Excrementa of the 
large intestines resembling thick verdigris paint. Penis about 18 inches 
long, 8 in circumference ; the lobe about 8 inches long, and 3 in circumference ; 
the lower surface depressed for the reception of the urinary canal.” 
11. Destitute of incisors or tusks in the lower jaw. 
Gen. XVI. TRICHECHUS. WALEUs.—Tusks of the up- 
per jaw greatly produced, and directed ventrally. 
23. T. Rosmarus. Tusks remote. 
Walrus, Sibh. Scot. p. 10., Macgillivray-, Edin. Phil. Journ. ii. p. 389.— A., 
rare straggler.
