HATCHER : OLIGOCENE CANIDJS 95 



S. Goggeshall in such manner that all the different bones may be readily detached 

 for examination and study. The pelvis, sacrum, missing lumbar and cervicals were 

 modeled from material very kindly loaned by Dr. M. S. Farr, Curator of Vertebrate 

 Paleontology at Princeton University. The scapulae have been modeled in plaster 

 and are purely conjectural, that element in Daphoenus remaining as yet unknown. 

 In modelling the scapula that of the cat has been followed rather than the dog. 

 Since in most skeletal features, aside from the dentition and skull, Daphoenus, as 

 has been shown, is decidedly more cat-like than dog-like. 



The general aspect of the articulated skeleton is that of a long, slender-bodied, 

 long-tailed and proportionately short-limbed carnivore. In form and general pro- 

 portions the appearance of the skeleton is that of a cat with a skull elongated as in 

 the dogs. The limbs are short in proportion to the length of the skull and verte- 

 bral column. The lumbar region is especially long and the lumbars exceptionally 

 heavy. The proportion of the axial to the appendicular skeleton is somewhat 

 intermediate between that which obtains in the cats and creodonts. 



DAPHCENUS DODGEI Scott. 



In our collections there is a left mandibular ramus (No. 573), which from its 

 massive nature, the character of the dentition and the horizon, Titanotherium beds, 

 in which it was found, I do not hesitate to refer to the above species. The ventral 

 border is hardly so sinuous as that described or figured by Scott, but in almost every 

 other respect it agrees accurately with Scott's description of the type. The teeth 

 are placed more closely than in any of the other species, the premolars being sep- 

 arated from each other and the canine by very short diastemata. The premolars 

 and molars are short but broad and P.^ and ^ have well developed posterior tuber- 

 cles and basal cingula. M.3 is implanted in the ascending ramus as indicated by 

 the alveolus, the tooth being wanting in the present specimen. 



PROAMPHICYON NEBRASCENSIS gen. et sp. nov. 



Among the material collected by Mr. Peterson is an imperfectly preserved skull 

 without lower jaw, a side view of which is shown in Fig. 6, which I have reluctantly 

 made the type of a new genus and species. Not only does it differ materially in 

 several important dental characters from any of the White River canidse yet 

 described, but moreover it presents characters quite distinct from those of Daph- 

 cenus and somewhat intermediate between those of that genus and of Amphicyon, as 

 will be shown later.
