Icticyon differs from Canis and agrees with the Indian Cuon in having but forty teeth, the last molar having disappeared from the upper and lower jaws.
The molar teeth are in the primitive form of trituberculy, and the premolars, as is so often the case with primitive animals, are unlike the molars in form, being less markedly selenodont.
The molar dentition is the typical one; the incisors seem to vary as to their presence or absence, and, if present, in their numbers.

Certain of the molar teeth of the middle of the series in both elephants and mastodons have the same number of principal ridges; those in front having fewer, and those behind a greater number.
Upper Molar of Mastodon arvernensis, viewed from below.
Mastodons have fewer ridges on their molar teeth than elephants; the ridges are also less elevated, wider apart, with a thicker enamel covering, and scarcely any cement filling the space between them.
In the advance of theirmolar teeth from a tritubercular to a grinding type, the author traces a curious parallelism between marsupials and placentals.
The premolar teeth of the cynopitheci are greater in length than breadth; those of the anthropomorpha are broader than they are long; and the first molar has four protuberances in the former, five in the latter.

In the extinct family of Lepidotidæ the teeth are conical or chisel-shaped, while blunt or molar teeth are on the inside of the mouth, which is small, and the suspensorium of the mandible is vertical or inclined forward.
With it was found a molar tooth of Rhinoceros tichorhinus.
I have seen fragments of a molar of Elephas, probably primigenius, from the clay at this spot, and also a bone of a ruminant, probably Cervus megaceros.
In the gravel near this place a molar of Elephas primigenius is recorded to have been found.
No land or freshwater shells have as yet been found, but some mammalian remains have occurred, among which is a molar of Elephas primigenius.
It lay with an unworn molar of Rhinoceros tichorhinus.
A molar of Elephas primigenius was found at this spot.
In the machairodus there is no upper true molar at all, while the premolars are reduced to two, there being only these two teeth above, on each side, behind the canine.
In the existing cats this process is carried so far that in the upper jaw only one true molar is left on each side.
The mandibles, like those of other Poduras, end in from three to six teeth, and have a broad, many-toothed molar surface below.
The right upper wisdom-tooth, the molar next to it, and the second lower molar on the left side, had all extensive gold fillings.
They are mostly of small size, and their molar teeth have sharp cusps.
Those having the head more or less elongated, and the parietal bones of the skull widest at the base, and gradually approaching towards each other as they ascend, the condyls of the lower jaw being on the same line with the upper molar teeth.
In the eagerness with which these bones are crushed, spicula or large pieces of them become wedged between the molar teeth, and form an inseparable obstacle to the closing of the teeth.
The head more or less elongated, the parietal bones widest at the base and gradually approaching to each other as they ascend, and the condyls of the lover jaw being on the same line with the upper molar teeth.
It is very much the more striking as it relates to the molar teeth, which differ so much in the species of the genus, and in which consequently I should have expected variation.
He insists strongly (page 78) on the "persistence and uniformity of the characters of the molar teeth in the earliest known mammoth, and his most modern successor.
From this basis the roots of the molar are developed, and increase in length, to keep the worn crown on the grinding level, until the reproductive force is exhausted.
These characters indicate the fifth molar (or set of molars) of the whole life-series.
A year hence, the central incisors will be worn quite flat, and their marks obliterated; the canines will be fully grown tusks, the second molar will have reached its full height, and all the teeth will be of the same level.
The first molar cuts the gum at two weeks old, is in full use at three months, and is shed in the course of the second year.
The molar in present use has a length of about nine inches, and a diameter of three and a half.
There are three molars, of which the first is worn quite smooth: once this surface was crowned with four cones; but the third molar had not then appeared.
Grinding surface of unworn right upper molar tooth of Anchitherium; b, corresponding surface of unworn molar of young horse; c, the same tooth after it has been some time in use.
It further differs from the other Voles in the fact that the molar teeth become rooted in the jaws of the adults.
The molar teeth have sharp tubercles on the crown.
The surface of the molar teeth in all the Voles presents a pattern of alternating triangular prisms.
It was a molar which had already been filled; no remedy was possible.
A snapping sound was heard, the molar had broken while being extracted.
It is by virtue of it that the greatest advancements of knowledge have been achieved, the cardinal discoveries in Molar and Molecular Physics, Biology, Geology, and all departments of Science.
It is these, indeed, for the most part that constitute the special subject-matter of the sciences inMolar as well as in Molecular Physics.
The Paca (Coelogenys) differs from the Capybara in the complex structure of his molar teeth.
In addition to this, other evidence comes from the results of an examination of the grinding surfaces (crowns) of the molar teeth.
The actual material consists only of two human teeth of the molar series.
More important and definite is the direction of the grinding surfaces of the molar teeth.
Now such fusion of roots is not absolutely unknown at the present day; but the third molar or wisdom tooth is most frequently affected.
In respect of size, the teeth of the Dordogne individual surpass those of the Mauer jaw, but the first lower molar has proportions similar to the corresponding tooth of that specimen.
The resemblance depends primarily upon the curious fusion of the roots in the molar teeth.
But some of the molar teeth are further distinguished in a very remarkable way, for the roots supporting the crown of the tooth are conjoined or fused: they are not distinct or divergent as is usual.
The grinding surface of the first right lower molar tooth from Taubach.
The molar teeth are of inadequate size if the skull-cap is that of an ape, whereas they are slightly larger than the corresponding teeth furnished by primitive existing human types.
The molar teeth were large with stout and divergent roots.
But the mandible is wanting, and the molar teeth of the upper set are absent.
The test of combined molarroots therefore provides a means of subdividing a group of examples otherwise similar, rather than a mark of recognition applicable to all alike.
One is the first lower 'milk' molar of the left side.
The occurrence is extremely unusual in the othermolar teeth of modern men.
The molar teeth are all slightly different in structure, and increase in size from first to last; they bear no slight resemblance to those of the human being.
