DIVISION I. VERTEDIIAL ANIMALS. — CLASS I. JIAMMALIA. 



Color; niid, ai-curdiiin- to Ilaiis Eixodc, is well-tasted : the fins and tail also 

 are niiieli relisiied liy tlie Crreeulandoi's. The oil, though not al.mndant, is 

 of the finest qnalily. The internal membranes arc used i'or windows and 

 bed-eurtains, and from the sinews is prepared a strong thread, whieh is em- 

 ployed in the nianut'aeture (if garments. 



The higher latitudes of the aretic regions appear to be the favorite haunts 

 of these animals. They are numerous in Hudson's Ba)', Davis's Straits, and 

 on some parts of the northern coasts of Asia and America, where they fre- 

 quent the large rivers. Steller found them at Kamschatka, and at one time, if 

 not at present, they were plentifid in the (julf of St. Lawrence, going with the 

 tide as high as (Quebec. According to ilr. Scorseby, they avoid the ice, and 

 seek those places where the water is clearest and smoothest. They are Iieau- 

 tiful and harmless creatures, and are often seen sporting on the wave in herds 

 of thirty or forty, bespangling the water with their s[)lendid whiteness. They 

 also follow ships and boats without fear, playing around, and observing them 

 with the greatest curiosity. 



Genus DELPiilNAPTEra's. The l)cli)liina[)terus is distinguished from the 

 dolphin by having no dors;d fin, and from the beluga by baving in front of 

 the head a slcndi'r beak. It liclongs to the high latitudes of the soutliei-n 

 hemisphere, where several species ha\e been ascertained. 



Lii-Ijtlnndplcriix J'rron/'i. — The Dolphin of Peron. This species is about 

 six feet ill length, I'le^ant in its ibrm. and regular in all its proportions. The 

 beak as far as the eye is of a satin and silvery whiteness, as also arc the sides, 

 the abdomen, the pectoral fins, and a part of the tail. The upper part of 

 the back is of a deep) bluish-black color, rising at the eyes, where the white 

 appears like a cross, ami extending downwards on the flanks, gi\ing llie 

 animal the appearance of Ijcing covered with a black cloak. It lias all the 

 sportive propensities of other s[)eeics, gamboling round vessels, following 

 them, <ir inspecting tlieni 'witli apjiarent wonder. 



Genus GLODicEruALUS. The generic name signifies glohe-hertded, and 

 well dcscrilies the very prominent and round head of the animal. Four 

 species are named, the iirst three of which, viz., (r. Hissll, (r. Leucocepli- 

 ah{s, and ''/. Fiisck-^, we shall pass over, ami confine our remarks to the 

 most interesting one of the group. 



(/. Drd urlor . — The Deductor, or Ga'lng A\'liale. The dcductor 

 varies from sixteen to twenty-four feet in length. Nearly the whole body 

 is black, smooth, and shining, like oiled silk; the breast and belly are some- 

 what lighter. The diirsal fin is about two feet long at its base, takes a curve 

 backward, and is crescent-shajicd at its extremity. The ])cctora]s arc from 

 six to eight feet long, narrow and tapering at their extremities, and the tail 

 is large, extending to about five feet. The most peculiar feature is the head,
