the genus Getiosaurus was proposed was not read until June 

 30, 1841 (Froc. Geol. Soc. London, vol. iii, pt. ii, :N'o. 80, pp. 

 457-462), it is evident that Cardiodon may be jnstlj given 

 precedence in time. 



Figures of the tooth representing the latter genus are shown 

 in- Odontography^ Yol. II, Flate 75(2, figure 7, a-d. The legend 

 at the bottom of this plate states that the latter was " published 

 by H. Bailliere, 1844." In the explanation to the plate (loc. 

 cit., p. 20), the specific name Cardiodon rugulosus is proposed. 

 Four species of Getiosaurus were named and described in the 

 Report of the British Association for 1841, pp. 94-102, London, 

 1842. In the case of neither genus, however, were any species 

 noted in the original description. 



Entelodoii and Elotherium. 



Entelodon Aymard, 1846, Ann, Soc. d'Agric, Sci., Arts et Commerce du 

 Puy, tome xii, for 1842-1846, p. 227, 1 planche, Eepriut, p. 1, 1 planche, 

 1848. 



Elotherium Pomel, 1847, Bull. Soc. Geol. France (2), vol. iv, p. 1083. 



. In April, 1894, Frofessor Marsh prepared a pap)er on the 

 Restoration of Elotherium^ and in looking up the litei-ature 

 previous to publication it was found that much confusion 

 existed in regard to the early nomenclature of the group. Few, 

 if any, authors have recognized the fact that the siiilline genus 

 Entelodon (Ann. Soc. d'Agric, Sci., etc., du Fuy, vol. xii, 1846) 

 is prior in date to Elotherium (Bull. Soc. Geol. France (2), 

 voL iv, 1847), Aymard's paper on the former being almost 

 invariably quoted as 1848. Before Frofessor Marsh's article 

 was ]3rinted no data were obtained of sufficient accuracy to 

 warrant the adoption of Entelodon^ yet facts were subsequently 

 acquired proving that Elotherium should be assigned a second 

 place. 



Through the courtesy of Baron de Yinols, Fresident of the 

 Society of Agriculture, Science, etc., at Fuy, and recently of M. 

 Leopold Delisle, General Administrator of the ISTational Library 

 of Faris, it has been learned that Yol. XII of the Annals of 

 the Fuy Society, containing Aymard's paper, was printed by 

 Gaudelet at Fuy, in 1846. In his letter on this subject, 

 Baron de Yinols states : " Ce qui a pu faire confondre la date 

 de 1846 avec celle de 1848 c'est que cette derniere date est sur 



144-150 were printed in 1845. Plates 1 and II published with. Part III are 

 general and are dated 1845. 



The facts given in a note by W. H. Brown (Woodward and Sherborn's 

 Catalogue of British Fossil Vertebrata, London, 1890, p. xxix) do not coin- 

 cide with those here stated.
