It will be seen that these teeth are slightly smaller than those of 

 both the type of Equus niobrarensis and those of the Alaskan skull 

 from Tofty. Likewise the protocones are longer, equaling the length 

 of that of the fourth premolar of the Tofty skull. These teeth have, 

 too, a greater complication of the enamel which bounds the opposed 

 faces of the two cement lakes. That on the hinder face of the front 

 lake is especially folded, forming five loops. However, it is only a 

 little more complicated than that of the lakes of the first molar of the 

 Tofty skull. 



The numeral (2) on the map here shown marks Hotham Inlet, 

 latitude 162 West, where, close to the Arctic Circle, Mr. L. S. 

 Ouackenbush (Bull. Amer. Mus. Nat. Hist., Vol. 26, p. 121, pi. 18) 

 found, in very barren deposits, the metatarsal bone of a horse. This 

 specimen, as well as others found by Mr. Ouackenbush, are m the 

 American Museum of Natural History, New York. 



Various specifically unidentifiable remains of fossil horses have 

 been found around Eschscholtz Bay. The earliest mentioned were 

 discovered by Captain Beechey and his companions in 1827 at Ele- 

 phant Point. The parts then found were an astragalus, a metacarpal, 

 and a metatarsal. They were mentioned and figured by Buckland in 

 the second volume of the Narrative of the Voyage of the Blossom, 

 p. 597, pi. 3, figs. 13-15. 



The same region was visited by the ship " Herald," in 1848 ; and 

 some bones of horses, together with those of various other extinct 

 animals, were found. These were described by Sir John Richardson 

 in the Zoology of the Voyage of the Herald, pp. 17-20. Of the horse 

 he described a sacrum, a right os innominatum, a part of a right 

 ischium, a radius and part of the attached ulna, a whole tibia and 

 parts of four others, two astragali, and a part of a metatarsal. To 

 these were applied simply the name, Equus fossilis. All these speci- 

 mens are in the British Museum of Natural History (Lydekker, 

 Cat. Foss. Mammalia, Brit. Mus., pt. 3). None of these seem to have 

 been figured. 



In the summer of 1907 Mr. L. S. Ouackenbush explored the 

 region around Eschscholtz Bay in the interests of the American 

 Museum of Natural History, New York. His report was published 

 in the bulletin of that museum, Vol. 26, 1909. On the north shore 

 of the bay, eastward of Chloris Peninsula, he found some remains 

 of an undetermined species of horse. In the same locality he found 

 Elephas, Bison, Ovibos, Rangifer, Canis, and Castor (op. cit, p. 106). 

 This locality is marked by the numeral (3) in the map here shown.
