The male skull, No. 332513, is represented by the frontal bone united with a larger part of the face, a separated left temporal, and the right half of the lower jaw. A large Inca bone, recovered from the beach a year later, may also belong to the same specimen. The missing parts are probably still somewhere in the sands of the beach where there is going on a very instructive scattering and redeposition on a 4 to 6 feet lower level of the contents of the old bank.
The skull is that of a male of somewhat over 50 years of age, judging from the moderate to marked wear of the remaining teeth. It is a normal undeformed specimen, and the same applies to the bones of the skeleton.
Notes and measurements.—The frontal shows a medium development, no slope. The supraorbital ridges are rather weakly developed for a male, leaving the upper borders of the orbits rather sharp.

| Diameter nasion-bregma | 11.5 |
The skull as a whole was evidently mesocephalic, and neither low nor very high. The thickness of the frontal is about medium for an Indian.
The face is of medium proportions and strength, with rather large orbits, good interorbital breadth, medium malars, medium broad nose, and but moderate alveolar prognathism. The nasal bridge is not high, nasal bones fairly broad, spine moderate, lower borders well defined though not sharp. The sub-malar (canine) fossae are shallow.

The condyloid process of the lower jaw is high, mandibular notch deep. The whole jaw is strong but not thick or massive. It is Indianlike, not Eskimoid, in all its features. The teeth are of good medium size.
Skull No. 333383.—Of this skull I brought the right parietal with about one-third of the frontal; Mr. Krieger, a year later, the remainder of the frontal. Other parts are missing.
