age. Itis not a fresh skull; the bones are quite brittle and seem to be 
largely devoid of animal matter, but no claim is made that it is very 
ancient, and there is no probability that it is so. 
This cave skull (figure 3) is in all essential features closely related 
to the Calaveras specimen. It has similarly strongly developed 
supraorbital ridges, extending along the entire superior border of the 
orbits; similar depression between the ridges, over the glabella; simi- 
larly marked nasal depression below the glabella, and about the same 
development of the marginal process of the malar, of this bone itself, 
of the zygoma, and of the nasal spine. There seem to have been pres-

ent also shght nasal gutters. The orbits in the specimen catalogued 
as no. 225172 are slightly more quadrangular, but otherwise are nearly 
hke those in the Calaveras skull. The alveolar process in no. 225172 
has suffered no absorption; owing to this fact and to the absence from 
the cave skull of injuries, the lower parts of the faces of the two speci- 
mens differ in appearance, but this dissimilarity is not morphological. 
The forehead in no, 225172, though slightly narrower than that in the 
Calaveras skull, is very nearly as well arched. On the whole, the 
structural resemblance between this cave skull and the Calaveras 
cranium are close enough not only for racial, but even for tribal, 
relationship.
