286 CLASS MAMMALIA. 



appears to be an approximation to Ovis in the forms of 

 the animals, though the horns still retain the structure 

 which prevails in the Naemorhaedine group, and indeed so 

 closely, that if other distinctions, and an immense geogra- 

 phical distance did not interpose, they might have been 

 left in the same racemus. The horns of the Aploceri are 

 simple, conical, obscurely annulated, the points bent back ; 

 they have no lachrymary sinus, no black and moist muzzle, 

 no inguinal pores ; their skulls are solid and heavy, their 

 limbs strong, the tail rather short, and they are exclusively 

 confined to the western hemisphere. The want of a lachry- 

 mary opening in this and other ruminating groups is most 

 commonly an indication of their residence being confined 

 to high latitudes, or elevated regions, and the remark is 

 verified in the present case, at least as far as the only spe- 

 cies perfectly established is applicable, and not disproved 

 by those whose existence is more problematical. 



Woolbearing Antelope. {A, Lanigera.) This animal 

 was first noticed by the Spanish missionaries in 1697, 

 and subsequently by Venegas, in his History of Cali- 

 fornia. Captain Vancouver afterwards brought a muti- 

 lated skin to Europe, and the late Lieutenant-general 

 Davies presented a complete specimen to the Linnaean 

 Society of London. From this subject M. De Blairi- 

 ville published a notice under the name of Rupicapra 

 Americana, in 1816. About this period Messrs. Lewis and 

 Clark returned from their valuable travels, and brought 

 another imperfect skin, from which Mr. Ord drew up his 

 notice under the name of Ovis Montana in May 1817, and 

 in the same year a more detailed description, chiefly taken 

 from the specimen in the Linnaean Society, was drawn up 

 and afterwards published in the Transactions, vol. xiii. 

 Some additional information relative to the species was de- 

 rived from the Indians, and particularly from a memoran- 

 dum drawn up by Donald M'Kenzie, Esq., chief factor of
