narrow line of white on their posterior edges. Buttocks, for some inches anterior to the tail, and belly white. Tail like the

OVIS ARIES, L.—Common Sheep. 
A specimen, No. 164, was procured on account of its peculiarity in having four horns that 
are well developed, being about eight inches long ; one on each side erect and one turned down. 
It is said that many years ago the proprietor of an extensive hacienda on the Rio Grande 
owned a large number of sheep possessing this peculiarity, and that the number of horns to 
each individual was never less than three, and often as many as seven. His flock was driven 
ofl“ by the Navajoe Indians, who still graze large numbers of these animals in the mountains of 
New Mexico, among them many anomalies of this kind.
