Bison Latifrons, Lady. 23 



Bison latifro)is, according to Leidy, hns been found in the 

 Quaternary of California, Pennsylvania, Georgia, South Carolina, 

 Kentucky, Mississippi and Texas. 



Tlie fossil remains ot B. latifrons are found associated with 

 tliose, tlie Megatherium and Mastodon, and other species peculiar 

 to the Upper Tertiary ?nd Quaternary. 



There have been three, by some authors, four distinct species 

 o' extinct American oxen described. Leidy in his Memoir on Ex- 

 tinct Species of American Ox describes four, viz: Bison latifrons, 

 Bison autiquiis, BootJieriiim cavifrons and Bootheriiim boinbifrons. 



The species Bootlicriiim cavifrons seems to have been estab- 

 lished by Dr. Leidy, on a specimen vvhich Mr. Thos. Kite, of Cin- 

 cinnati, took to Pniladelphia in 1S52 for the inspection of Dr. 



Leidy. 



'J'he specimen was found near Ft. Gibson, on the Arkansas 

 River, in an Lidian hur, where it had been used as a seat; tlu; 

 original locality is not known. To this species also Dr. Leidy re- 

 fers Bos pailasii of DeKay. DeKay described the specimen 

 referred to in a paper read before the Lyceum of Natural History of 

 New York, July yth, 1827.* 



The specimen described was a fragment of a cranium from 

 New Madrid, on the Mississippi, which was ejected by the earth- 

 quake of 1812. DeKay gave the specimen the provisional name 

 oi Bos falasii, referring it to a species described by Pallas, found 

 in Siberia. 



Dr. Wistar described a fossil cranium with both horn cores 

 attached, found at Big Bone Lick, Ky. ; to this Harlan gave the 

 name Bos Inunbifrons, which Leidy refers to genus Bootherium 

 as B. bonibifrons 



It will be of interest to refer for a moment to some fossil 

 remains of oxen described by Lydekker in the Geological Survey 

 of India. Five species are described by him, and the measure- 

 ments of the horn cores of three of the largest is given below. 



Bos NAMADICUS : 



Length of horn cores, upper surface, 39 inches. 



" " " lower " 32 " 



Circumference of base 12.5 " 



Interval between the tips ... .30.0 " 



Hackett's specimen from Narbudda Valley, circumference of
