1904.] REMAINS OF ANTHRACOTHERIUM. 457 



taining lignite-deposits in various localities, very different opinions 

 have been held at different times. The Italian geologist General 

 Albert De La Marmoi-a, who was the first to mention the coal, 

 ascribed it to the Lower Cretaceous (l^eocomian) *, and was 

 followed in this determination by Bouvyt. 



The only writer who correctly guessed the age was Jules Haime, 

 who, from the examination of Molluscs in the lignite deposit, was 

 inclined to assign it to the epoch of the '' gypses de Provence," 

 which are of Oligocene age. He was positive in asserting that 

 the coal overlies the Nummulitic formation, adding that this 

 circumstance was well known to the miners themselves J. 



All the subsequent writers, however — Bouvy §, Yidal |j, Her- 

 mite ^, de Lapparent ** — have considered these lacustrine beds 

 to be Lower Eocene, taking it for granted that the Nummulitic 

 (Middle Eocene) overlies the freshwater deposits. This must be 

 either an error of observation, or else the reputed Nummulites 

 were not ISTummulites at all. 



Mr. Thomas was successful in obtaining, in the house of a miner 

 at Inca, several remains of Anihracotherium, which, according to 

 information received, were from the upper part of a lignite-mine 

 at Sineu, Majorca. A complete jaw, believed to be of the same 

 aiiimal, was said to be in the " Academy of Madrid." 



The more important of these remains, here exhibited, are two 

 more or less complete right and left second upper molars, and 

 a beautifully preserved penultimate right upper premolar (^j. 2) 

 (PI. XXIX. fig. 1). It is on these teeth that the specific deter- 

 mination rests. The molars (PI. XXIX. figs. 2 k 3) agree perfectly 

 in size and shape with a second upper molar described and figured 

 by G. Ouvier ft, and forming part of one of the type specimens 

 of Anthracotherium magmmi from the lig-nite of Cadibona, near 

 Savona (Liguiia). The premolar agrees with a similar tooth of 

 the same deposit figured by Gastaldi %%. 



A. magmmi is the predominant mammalian species in the lignite 

 of Cadibona ; there remains little doubt, therefore, that the lacus- 

 trine deposit of Majorca is of the same age. The Italian deposit 

 is usually placed in the Upper Oligocene ; however, the mammals
