vol. Ii. p. 926) proposed the generic term Mefarctos ; and in the 

 following year (' Animaux Fossiles et Geologic de 1'Attique,' p. 37, 

 pi. vi. figs. 1, 2) included in it both the Eppelsheim Gulo diaphorus 

 and the Pikermi Gulo primigenius. making, however, no mention 

 of the generic terms Pseudocyon and Simocyon. In 1862 Hensel 

 (Monatsb. k. preuss. Ak. Wiss. [volume for 1863] p. 566) came to 

 the conclusion that, on account of the difference in the number of 

 their teeth, Gaudry's reference of the Eppelsheim and Pikermi 

 forms to the same species was erroneous ; and he accordingly applied 

 the name Simocyon primigenius to the latter. Assuming that both 

 specimens belong to the same genus (of which there is no doubt), it 

 is evident that the generic term Simocyon is the correct one ; and 

 that the specific name diaphorus belongs to the Eppelsheim, and 

 primigenius to the Pikermi form, if the latter be distinct. Seeing 

 that no differences can be detected between the two forms with the 

 exception of the variation in the number of the premolars, and 

 bearing in mind the instances of Icticyon venaticus and Hycena 

 felina, the two forms are provisionally associated in this Catalogue.

 genus is evidently between the Bears and the Dogs.

M. 412. Cast of the left ramus of the mandible, showing the two 

 true molars, the two last premolars, and the alveoli of 

 plnTl and pln72. The original of this specimen is from 

 the Upper Miocene of Eppelsheim, Hesse Darmstadt ; and 

 is believed to be in the Museum at Darmstadt. It is the 

 type of the species ; and is figured by Kaup in the Oss.
