PLATE XII. {Concluded.) 



tooth from Gardiner, Me. Presented by Dr. 0. T. Jackson." Some of the blue clay of the original 



matrix still remains between the fangs of the tooth. 

 Fig. 14. Third right upper molar, from Gardiner, Me., from Dr. Packard's Plate (Mem. Bost. Soc. Nat. 



Hist, V.'l. I. PL vii, Fig. 18 a). Strictly comparable with the corresponding tooth in Figs. 12 (Bos (au~ 



nu) and 6 (B. americanm). Its much closer resemblance to that of Bos tauras than to that of B. ameri- 



caiins will be at once noticed. 

 Fi". 15. First right upper molar, from Gardiner, Me., from Dr. Packard's Plate (Mem. Bost. Soc. Nat 



Hi-t.. VoL I. PL vii. Pig. I s ). Strictly comparable with the corresponding tooth in Figs. 12 and 6. 



The infolding of the enamel at the inner posterior corner of the hinder crescent marks it distinctly as a 



tooth of Bos faurus, and as not at least a normal tooth of B. americamts. 



UoxK. — In the text of this work (pages 90, 91, put in type over four months ago) I left the question of the 

 identity of the tooth from Gardiner, Me., a somewhat open question, though stating it to be my conviction that 

 they were those of Bos taunts. A re-examination of the subject, in the light of a larger series of specimens of the 

 latter, fullv confirms this conviction. Of such identity I now believe there is not a reasonable doubt. 



To complete the history of the subject I have copied Dr. Packard's figures of the two molar teeth of which 1 

 am unable to give original figures.
