Felid^. 
Dr. Gray has examined the large series of skulls of Felidm in 
the British Museum, with the view of basing a systematic divi- 
sion upon them. With the exception of theGuepard, the skulls 
present very few tangible characters ; and even the peculiarity of 
the skull of the Lynxes is not very striking ; it consists in the 
lateral processes of the intermaxillaries and the frontal bones 
being elongate, nearly reaching each other, and separating the 
nasals from the maxillse. Dr. Gray directs attention also to the 
fact that the diurnal forms (with round pupil) have the orbit of 
a considerably smaller size than the nocturnal (with vertical 
pupil). Proc. Zool. Soc. 1867, pp. 258-277. The species are
