there is not so wide a lamina of bone to shelter the base of 
the claw as in the Felide. 
(4) The claws may be considerably arched, or they may be long 
and very slightly so. They are hardly ever (not except 
perhaps in Prionodon and Poiana) completely retractile, and 
often are not at all so. 
(5) The auditory bulla (except in Nandinia) is ossified, much in- 
flated, and shows externally that it consists of two chambers. 
(6) The bulla is not more prominent towards its inner than towards 
its hinder border. 
(7) There is an almost complete bony septum between the two 
chambers of the bulla, which may or may not be one behind 
the other. 
(8) The bony meatus auditorius is almost always short, and may 
have its anterior, posterior, or inferior margin most project- 
ing ; and it may be imperfectly ossified below. 
(9) There is a carotid foramen, or two carotid foramina, visible on 
each side of the basis cranii. 
(10) There is (except often in Viverricula) an alisphenoid canal. 
(11) ae palatine foramina are situated in the anterior half of the 
palate. 
(12) P- is generally and py constantly developed. 
(13) There is always an x, and generally an — 
(14) “+ is always present, generally large. 
(15) The antero-external cusp of F:* is generally very small. 
(16) 3, has almost always a considerable talon. 
(17) The outer incisors may greatly exceed the middle ones in 
size. 
(18) The humerus sometimes wants the supracondyloid foramen. 
(19) The bone of the penis is small, save in Cryptoprocta. 
(20) The ears are not very long, erect, and pointed. 
(21) The tarsus and metatarsus are very often bald. 
(22) One plantar pad (small or large), and one beneath each 
digit. 
(23) Anus opening on the surface or in the middle of a saccular 
cutaneous invagination. 
(24) Anal glands from one to five pairs ; generally one pair. 
(25) Very often prescrotal sceunt-glands. 
(26) Caecum generally present and small or moderate, but occa- 
sionally absent. 
(27) No very hard, horny, sharp-pointed, conical papillee on the 
dorsum of the tongue. 
(28) Hippocampal gyrus completely separated from that anterior 
internal portion of the superior lateral gyrus which is behind 
the crucial sulcus, by the continuation forwards of the calloso- 
marginal sulcus to join the crucial sulcus. 
(29) The coronoid process of the mandible is almost, if not quite, 
always less lofty relatively, and less backwardly produced 
than in the Felide.
