to give photographs of them in the present connection, as well 

 as photographs of mounted specimens from the Barren Grounds. 



For comparison with the Peary material the Museum has 

 three mounted specimens, two adult males and an adult 

 female, an unmounted adult male, and two calves a few weeks 

 old, from the Barren Grounds east of the Mackenzie, but without 

 data as to exact locality. For opportunity to examine also three 

 Alaska specimens, two old males and an old female, said to 

 have been taken a few miles inland from Camden Bay, I am in- 

 debted to the kindness of Mr. Hubert H. Vogelsang, taxidermist, 

 of New York City. 



As regards both skins and skulls, it has thus been possible 

 to compare the nineteen Peary specimens from Bache Peninsula 

 with nine specimens from the Barren Grounds. This com- 

 parison has resulted in the rather surprising discovery that the 

 Musk-Oxen of the insular lands west of Kane Basin differ very 

 markedly from those of the Barren Grounds to the westward, not 

 only in coloration but in shape and relative size of the basal 

 portion of the horns. As Ovibos moschatus (Zimmermann) was 

 based exclusively on the Barren Ground form (the type locality 

 being the Churchill River region), it seemed fitting to name the 

 new coast form in honor of the intrepid Arctic explorer, Lieut. 

 R. E. Peary, U. S. N., to whose labors in the high North the 

 Museum is indebted for a large amount of valuable material in 

 various lines of research. Since adopting this name in my 

 manuscript, however, Mr. R. Lydekker, of the British Museum, 

 has named the East Greenland Musk-Ox Ovibos moschatus wardi, 

 taking for his types a mounted male and female from East 

 Greenland, in the possession of Mr. Rowland Ward, the well- 

 known natural history dealer of Piccadilly, London, for whom 

 the species is named. (See Nature, Vol. LXIII, p. 157, 

 Dec. 13, 1900.) 



Although the Peary specimens came from Bache Peninsula, on 

 the western side of Kane Basin, they probably are referable to 

 the Greenland form, and I hence adopt for them Mr. Lydekker's 

 name, citing " Ovibos pearyi Allen, MS.," as a provisional 

 synonym, which may be accepted for the Grinnell Land animal 

 in case it should prove separable. On geographical and other 

 grounds, this appears hardly probable, as the Musk-Ox of this
