HOLLAND AND PETERSON: OSTEOLOGY OF THE CHALICOTHEROIDEA,. 383 
The specimen demonstrates the very remarkable fact that the Chalicotheriwm swalense 
was entirely destitute of incisor teeth in either jaw. ‘The intermaxillary bones are 
perfect to their tips, and consist of slender slips of bone converging to a sharp point; 
they show that no incisor teeth could have existed in the upper jaw at any period of the 
animal’s age. The anterior portion of the lower jaw is perfect to the alveolar edge. 
A detached canine is seen on either side, but the intervening space is without a vestige 
of incisors, and is contracted in correspondence with the convergence of the inter- 
maxillary bones, and sloped off to a fine edge. The upper jaw is also destitute of 
canines or of any trace of canine alveoli; but the lower jaw contains two canines, as 
shown in figs. la and 1b, the crowns of which are thick, cuneiform, and somewhat tri- 
angular, and slightly inclined forward, with a blunt apex. The specimen shows three 
premolars and the first true molar; the two back molars are absent. The characters of 
the molars are better seen in figs. 3 and 4, and are described in great detail in Dr. F.’s 
Memoir on Chalicothertum.” 
“ This beautiful specimen was originally in the Dadoopoor Collection of Messrs. 
Baker and Durand, and is now in the Museum of Marischal College, Aberdeen, Cast in 
British Museum.”

On pp. 429-433 the author describes the last right upper molar of a species, to which 
he gives the name of Chalicotherium sinense. On Plate X XIX, figs. 7-10, he gives 
views of this tooth. The specimen was “ obtained ina cave’’ by Robert Swinhoe, Esqr.

Dr. Gill in this paper locates the Chalicotheriide among the Artiodactyla. On p. 
71 he characterizes them as follows: 
“TIncisors deciduous from upper as well as lower jaws. Canines of lower jaw in- 
clined forwards, with compressed cuneate crowns. Placenta and stomach unknown.” 
On p. 76 he erects the superfamily Chalicotheroidea.
