ST.-GEORGE MIVART ON THE ALUROIDEA. 191 The outermost upper incisor is caniniform, and nearly as large as is the adjacent canine. - is a little separate from and a little larger than the canine, which it closely resembles. - is also caniniform, with a talon: it is separated by a long diastema from - ; and another about as long separates it from - . ?*-5 is a narrow, antero-posteriorly elongated tooth, with a conical backwardly-directed middle cusp, and with a small anterior cusp and a larger posterior one, at the base of the middle cusp. - , - , - , and - all join without diastemata. - has one large median cusp, with one small anterior and one rather large posterior cusp, and with a small internal cusp placed opposite the junction of the anterior and middle cusps. - - has two equal-sized outer cusps, and an inner cusp (larger than that of -"-) opposite their junction. The anterior outer cusp answers to the anterior outer one of --. ^A shows also a minute rudiment of a cusp answering to the postero-outer one of -'-. -1 2 is very similar to - ; but its inner cusp is smaller, and placed opposite to the more anterior of the two outer cusps. The outermost lower incisor has the postero-outer angle of its crown slightly produced. The canine is like it, save that this angle is more produced. The teeth p-^, p-j, p-g, and p ^ are all separated by diastemata (of which that between p-- and p-- is the longest), while p^, ^ , and j ^ adjoin the one to the other, p-y is caniniform. p-- is also caniniform, with the addition of a minute anterior cusp and a slight talon, p-g has a talon which develops two small cusps, while the anterior cusp is more developed than in p--. p- is like p-^, with all its cusps more developed save the principal cusp. ^ has three external cusps (whereof the posterior cusp is the smallest), with an internal cusp placed opposite to the hinder part of the middle outer cusp. ^ is similar to jj-j, save that the postero-external cusp is relatively larger and subdivided, and that the internal cusp is connected with it and with the antero-external cusp by ridges. Here ^ not only equals, but (at least sometimes) even exceeds ^-^ in size. In the milk-dentition (judging from De Blainville's figure) - and - may resemble - - and -^- ; but D75 and 574 are unlike any of the permanent teeth, since they seem each to consist of two nearly equally developed external cusps, and they are much more sectorial in character than are the teeth which succeed them, whether from below or from behind. In a word, the milk-dentition is more carnivorous and less insectivorous than are the permanent teeth. Both the internal condyle and olecranal fossa of the humerus are perforated. There are no signs of scent-glands. I can find no record of the anatomy of its soft parts. It appears to me that, of all other Viverrida, Eupleres comes nearest |
