CHARACTERS OF THE PARADOXURINyE. 397 



slits, moreover, are subparallel and only slightly convergent pos- 

 teriorly, so that the upper surface of the rhinarium is only a 

 little narrower behind than in front. 



In Nandinia the rhinarium, seen from the front, is a little 

 narrower and higher tlian in Arctogcdidia; its upper edge is less 

 markedly biconvex, owing to the sulcus being shallower. The 

 upper surface has a shallower anterior notch, and is a little 

 longer as compared with its width than in Arctogalidia and is 

 quite as wide behind as in front. 



The rhinarium of Ar diet is differs from those of the other 

 Paradoxuriiie genera here described in one or two points. The 

 median groove extends over the upper surface-, but is sunk in a 

 much shallower depression. Hence the superior margin of the 

 anterior sui-face is not markedly biconvex, but is fairly evenly 

 convex from side to side-, with Only a small and shallow median 

 notch. Seen from above, this mai-gin is similarly Convex from 

 side to side, with a small median notch; The infranarial portion 

 in front is shallower and has a more evenly rounded inferior 

 border, and, when seen from above^ the narial slits converge 

 posterioi'ly as in Faradoxurus-. 



In my description of the rhinaxia of the Viverrine genera 

 Viverra, Civettictis, etc., I said : — '' It is impossible to affirm the 

 existence of any absolute difference between the rhinaria of the 

 Viverrinae collectivel}' and of the Paradoxurinje." Coufii-mation 

 of this is supplied by a study of this organ in the Paradoxnrinse ; 

 for, although the rhinarium of Faradoxurus^ Arctogalidia, and 

 Nandinia differs from that of the Viverrinte in being very deeply 

 sulcate above and in front, the rhinarium of Arctictis, a genus in 

 most particulars the least Viverrine of all the Paradoxurinse, is 

 much less deeply and widely sulcate-, its supero-anterior margin 

 being evenly convex from side^ to side with a quite small median 

 notch. The convex curvature of this border recalls that of the 

 rhinarium of the African Civet [Civettictis), although the median 

 groove of the rhinarium is deeper both above and in front than 

 in that genus. On the other hand, the rhinarium of the large 

 Indian Civet [Viverra zibeiha), with its upper suiface biconvex, 

 is more like the rhinarium of Parddoxurivs than is tlie rhinai-ium 

 of Arctictis. In the shape of this organ, therefore, the genera of 

 Viverrinae and Paradoxurin&e intergradei 



The facial vibrissa3 raAj be briefly dismissed^ The tufts are 

 without exception normal in number, the mystacials in particular 

 being long and rigid. Of the two genal tufts on each side, the 

 inferior is situated in a line With the cotner of the mouth and 

 the superior a little higher up and posterior to it. The least 

 developed is the interrainalj but it is always present and not far 

 behind the mandibulai- symphysiSi
