In a letter to the author, Mr. Willcox writes that, as nearly as he can recollect, the diameter of the horn-core was about 5 or 6 inches.
8. Vero, St. Lucie County.—Sellards (8th Rep., Florida Geol. Surv., p. 150) stated that an extinct bison is represented in the collection of the Florida Geological Survey by a number of teeth, the distal end of a humerus, and some foot-bones. They were supposed to have been derived from stratum No. 2.
When in Vero in 1916, the writer secured a much-worn upper left premolar 3 of Bison from the base of the muck layer No. 3. It is in some respects different from the corresponding tooth of the existing bison. For lists of the species found at Vero and for a discussion of the geological age the reader may consult pages 381 to 383.
9. Arcadia, De Soto County.—In the U. S. National Museum are some teeth of Bison, obtained at or near Arcadia, on Peace Creek. In general, these resemble closely the corresponding teeth of B. bison. Leidy (Trans. Wagner Free Inst., vol. II, p. 22) mentioned a tooth and a first phalanx of Bison from Peace Creek. These are probably in the collection of the Wagner Free Institute.
In the U. S. National Museum (No. 1989) is a hinder cannon-bone from Arcadia. It resembles the corresponding bone in B. bison, but doubtless belonged to a species now extinct. Lucas (Proc. U. S. Nat. Mus., vol. XXI, p. 767) referred the teeth and the metacarpal to B. latifrons.
In the same museum is a calcaneum labeled as collected on Peace Creek by J. F. Le Barron. The reader may consult page 381 for further information.
10. Labelle, Lee County.—Remains of Bison apparently have been found at Labelle, or near there. Leidy, in Dall’s report (Bull. No. 84, U. S. Geol. Surv., p. 129) referred this to B. latifrons. The bison, Elephas columbi, Equus fraternus, and a mylodon were supposed to have been buried in Pliocene deposits, but this opinion appears to be erroneous. Sellards (8th Rep., p. 102) has shown that the elephant and probably the horse were in Pleistocene marls. As shown on page [384], the elephant is Elephas imperator.
11. Palm Beach, Palm Beach County.—In his eighth report, Sellards (p. [105]) stated that a femur of an undetermined species of Bison was found near this place, in the Palm Beach Drainage Canal. In the collection of the Museum of Comparative Zoology, at Harvard University, are a front cannon-bone, lacking the epiphyses, and the proximal end of a humerus. The size of these indicates that they belong to B. latifrons. The glenoid cavity measures 80 mm. by 60 mm. The neck of the humerus is 100 mm. wide.
