16 Mr. F. Bates on Nero Genera 



condyloid foramen of the humerus, in which it was said to 

 differ from all the other Ursidas. This group has been adopted 

 as a distinct genus by the author in his 'Arrangement of the 

 Families of Mammals.' 



In reference to the statement that the supracondyloid foramen 

 is absent in all otlier Ursida3 (" qui manque a tons autres 

 Ursides "), it may be well to recall that it is developed in the 

 humerus of a fossil bear preserved in the palgeontological col- 

 lection of the Museum at Paris, and figured by Cuvier and 

 Blainville (see ' Ost^ographie des Mammiffei-es,' tlrsus, pi. xvii. 

 desc. p. 93) ; but, as remarked by De Christol and Blainville, 

 that specimen is doubtless exceptional or " monstrous," it 

 being the only one known among hundi-eds examined ex- 

 hibiting such a peculiarity. The same bone has been re- 

 ferred to by Dr. John Struthers, in the 'Lancet ' (1873, vol. i. 

 pp. 231, 232), in comments upon the hereditary occurrence of 

 a supracondyloid process in Man. Judging by the figm'e of 

 the humerus of Tremarctos ornatus gis^en by Blainville, the 

 supracondyloid foramen appears, however, to be a normal 

 characteristic of that species ; but it would be desirable that 

 such supposition should be proved or disproved by the examina- 

 tion of other specimens, and my chief object in this communi- 

 cation is the hope that it may elicit such information. 



I venture also to add another reference that has been over- 

 looked by Dr. Gray as well as Dr. Fitzinger. In the ' Pro- 

 ceedings of the Zoological Society of London ' for 1867, p. 268, 

 Dr. Gray has proposed a genus Viverriceps for several Felidaj, 

 and among them the FeJis planiceps of Vigors and Horsfield ; 

 and in the ' Sitzungsberichte der Akademie der Wissenschaften 

 zu Wien ' for 1869 Dr. Fitzinger has based another genus 

 {Ailurogale) on the same species. A subgeneric group had, 

 however, long previously been proposed by Prof. Gervais {op. 

 cit. p. 87, 1855) for that species, designated " Ailurin " (Latin, 

 u^lurina)^ and distinguished by the double-rooted false molars 

 of the upper jaw. In my 'An-angement of the Families of 

 Mammals ' I have retained both j^lurina and Viverriceps 

 (restricted) as genera.
