A model in full relief of Dinohyus hollandi, a photograph of which is given on 
Plate LXII, has been made by Mr. Theodore A. Mills under the direction of the 
writer. An examination shows that this figure is at variance with the painting 
prepared by Mr. Charles R. Knight under the direction of Professor Henry Fair- 
field Osborn (72a, p. 713). Archxotheriwm is represented in that figure as having 
long stiff bristles on a very broad neck, with the ears as in the Swinx, and as having 
heavy pendant wattles hanging from the bony tubercles of the inferior margins of 
the mandibles. Although the bristles and the broad neck shown in Knight’s illus- 
tration may be correct, there is reason to believe that the ears were placed lower 
down and were more drooping, judging from the position of the external auditory 
meatus, which in the true pigs is directed upward and slightly outward, while in 
those American genera of the Entelodontide, in which this part is known, the 
auditory meatus is directed nearly horizontally outward and has a prominent over- 
hanging border on the upper side formed by the squamosal. In the restoration by 
Mr. Mills the dependent processes on the inferior border of the mandibular rami of 
Dinohyus are represented as supporting muscles, it being believed by the writer 
that these processes, at least in the genus Dinohyus, existed for the attachment of | 
muscles in order to give required strength to this portion of the head. The model, 
of which the figure is given, is of course to a certain extent conjectural, but is 
believed by the writer to very fairly represent the animal as it was in life, and he 
takes occasion to compliment Mr. Mills upon the skill which he has shown in 
carrying out the suggestions made to him. 
Conclusion. 
While the osteology of at least two genera of this interesting family is now 
quite completely before us, I make no attempt to present a succession of species, as it 
seems to me that we have not yet the necessary material in order to satisfactorily 
study the more detailed questions of the phylogeny of this group. Aymard and 
Pomel with the extremely limited material representing this family at their com-
