lightly grizzled on anterior part of back by tij^s of golden-brownish ). 
Cranial characters. — Adult and old males: Rostrum rather narrow (in 
old age compiH'sscd in front of orbits); vault of cranium low, flattisb; 
frontal shield of moderate breadth, Mat or depressed (sometimes snlcate 
medially), ratlu'r short-pointed, sloping gradually to plane of muzzle, and 
only slightly dished in fronto-nasal region; postorbital i)rocesses ])eg-like, 
horizontally outstanding; sagittal crest low, reaching forward about half¬ 
way (in extreme age a little more than halfway) from iniou to postorbitals; 
zygomata broadly spreading and bowed; palate of median breadth; post¬ 
palatal shelf broad and Mat (in type, au aged skull, less broad ); squamosal 
shelves broad; scpiamosal root of zygoma not vertically expanded; infra- 
jngal ju'ocess of maxillary rather strongly developed; lower jaw short — 
much shorter than in sliheenensis, shoshone, and canadensis ; its ramus 
not Mattened. MVeth rather small: canines and molars much smaller 
than in slikeenensis. 
Skull of female relatively large (about same length as female 
but much narrower; much larger than female .s7i0^s'/^o?l6'and canadensis; 
vault of cranium moderately elevated, with tendency to fronto-jyarietal 
hum])-, facial ])art of skull large and long; frontal shield long, rather 
narrow, lyre-shape ])osteriorly, meeting sagittal crest some distance i)os- 
terioi’ to fronto-})arietai suture; frouto-nasal legiou well dished; palate 
and postjyalatal shelf long; zygomata moderatidy spreading and conspicu¬ 
ously outbowed ; under jaw hmg. 
Young females are l)est told by the teeth, especially the lower canines. 
In lahltanicus the lower canines are shorter and more slender than those 
oi slikeenensis. In the latter species they are longer and thicker — esj)e- 
cially thick in iniddle.
