various relations of animals. I shall therefore, agreeably to the direction afforded 
to me by this work, consider the Feline animals as one series, and the Viverrine 
animals as another series. That the animals of the former series are still imperfectly 
known, can clearly be demonstrated. As one proof, I shall adduce the Felis capensis 
of Forster. This distinguished naturalist, who was not unacquainted with the 
characters of Felis and Viverra, as defined by Linn;eus, clearly gives, as a property 
of the animal described by him, a lengthened head. Phil. Trans. Vol. LXXI. p. 5. 
Caput rostro magis acnto quam Felis cati. And M. Desmarest, in describing this 
animal in the Encyclopedic, offers in a note the following remark : — " M. Georges 
Cuvier, au quel on doit les rapprochemens que nous adoptons, a lui-m&me balance a 
regarder le chat du Cap, Felis capensis de Forster, comme line vraie civette. Dans 
son Mcmoire sur les especes de chats, il le considere comme une cspece voisine du 
chat serval; mais dans son dernier ouvrage (le Eigne Animal), il dit qull ne differe 
pas de la genette. v Concerning the Y r iverra tigrinn of Schreber, which was figured 
by Vosma?r, it more resembles a Feline than a Viverrine animal. M. Desmarest 
points out its affinity to the Felis gracilis ; and the name given it by Vosma?r, Chat- 
frizaam, shews that lie considered the characters of the Cat to predominate. The 
specific character also exhibits a remarkable agreement with our animal in the 
external marks, at the same time that it clearly indicates a specific distinction. We have 
thus in the Felis capensis, and in the Viverra tigrina Gmel., two animals of the Feline 
series, which are analogous to Viverrine animals ; and it may reasonably be expected, 
that future discoveries will make known others, which will unite the Felis gracilis 
with the Feline animals now known, and thus complete the series which is still inter- 
rupted. In the Viverrine animals, which are apparently better known, the series is 
more regular ; according to the relative development of the grinders, it has been 
arranged above in the following order : Genetta, Viverra, Suricata, Mangusta, The 
proportional development of the anal folliculi also confirms this disposition: in 
Genetta it constitutes a simple excavation ; in Viverra it is a pouch, divided into 
two sacks ; in Suricata, and particularly in Mangusta, it consists of an extensive 
portion of integument, with numerous folds, which passes over and incloses the 
anal aperture. These observations, which shew the regularity of the Viverrine 
series, and the interruption still existing in the Feline series, were necessary to my 
conclusion, that, although the Felis gracilis agree with the Mangusta javanica in its 
relations of analogy, the aggregate of its characters, which constitute its relations 
of affinity, associate it with Felis. In illustration of these observations, I shall intro- 
duce Mr. Macleay's words : — " The test of a relation of affinity is its forming part of 
a transition continued from one structure to another, by nearly equal intervals, and 
the test of a relation of analogy, is barely an evident similarity in some one or two 
remarkable points of formation, which at first sight give a character to the animal,
