(fig. 13 13), and is represented by much larger forms in the Pliocene 



of India, China, and Europe. In this genus the proximal extremity 



of the ulna (fig. 1300) has an elongated olecranon similar to that 



of Amphicyon and Cam's. There is also a third lobe to the upper 



carnassial (whereby it resembles the corresponding tooth of Hycend), 



while the first upper true molar is square 



(fig. 1 3 14) in one species, and imperfectly 



triangular in another ; the lower carnassial 



resembling that of Canis. The small H. 



anthracitis of the Middle Miocene of Italy 



may be identical with H. minntus. Before 



noticing the forms connecting Hyanarctus 



with Cants, we must mention some extinct 



genera more or less nearly allied to the 



present group, and which Dr Schlosser 



also regards as related to the Procyonidce. 



Among these are Simocyon (Pseudocyon or 



Metarctus) of the Pliocene of Greece and 



Hungary, in which the number of the

 would refer both to the Hyamidce. The former has the molars
