There is no median circumvallate papilla, but either one elongate one, or two small ones on either side. There is no patch of enlarged papillae on the dorsum, but those on the anterior half of the part in front of the circumvallate papillae are generally larger. A large free fold of mucous membrane projects horizontally from the anterior part of the fraenum on either side of it. In Hemigalea there is a marked free fold of membrane, similar to that of Genetta. There are three circumvallate papillae, one of which is median in position, and they form together an angle open forwards, not quite so obtuse as in the Civet. The flattened papillae are small and inconspicuous, and there are no conspicuous fungiform papillae. On the other hand, the conical papillae are specially modified on the anterior half of the tongue so as to form an oblong patch of enlarged, but smooth papillae at that part. This patch, however, is by no means so well defined a patch as that which exists in certain other genera, e. g. Galidia, Herpestes, and Crossarchus. The tongue of Nandinia is like that of Viverra civetta, except it is more pointed and has a relatively stouter lytta. The fungiform papilla, though scattered generally over its dorsum, are smaller and less conspicuous. There are only two circumvallate papilla, there being no median one. The flattened papilla are larger and more conspicuous, but not so large as (though more close set than) in Felis. Arctictis has a tongue like that of the Civet, except that there is a greater difference of aspect between the anterior and the posterior halves of its dorsum. On its anterior half the conical papillae are more conspicuous; and on its posterior half the fungiform papillae are less so. Speaking generally, the fungiform papillae are conspicuous and the conical papillae are small. There are seven or eight circumvallate papilla, which together form an angle of about 75°. The flattened papilla are hardly so conspicuous as in Nandinia. In the specimen of Herpestes I examined there were only three circumvallate papilla, and they were placed almost in a straight transverse line. The flattened papilla were small and inconspicuous. There was a very distinct patch of much enlarged so-called conical papilla on the dorsum of the tongue, each of these papillae being really flattened and having the appearance of having had its apex cut off. Fungiform papillae were conspicuous, and scattered over the dorsum between the patch of enlarged papillae and the circumvallate ones. In Cynictis I found three very conspicuous circumvallate papilla, which together form a right angle. Behind these are elongated flattened papilla, but hardly so conspicuous as in Nandinia. There is, on the anterior half of the dorsum, a wide, rounded patch of much enlarged conical papilla;, which are really flattened in form, and so disposed as to cause the patch to have the appearance of being marked with a series of lines of the shape called "embattled " in heraldry. Around this patch, and on the middle of the tongue behind it, the papillae are very small, and amongst them certain |
