skeletons, together with a few fragments of bird and turtle bones. They are 

 all very friable and appear much eroded on the surface. 



The human bones are all of mature age, and rather small. Most of them are 

 portions of two skeletons, apparently a male and female ; a few belonged to a 

 third skeleton, apparently male. Of portions of three skulls, the most perfect 

 is the greater part of a small- cranium, judging from its size, that of a female. 

 The base in advance of the occipital bone is broken away. The cranium is of 

 the brachycephalic type and bears a near resemblance to that of the ancient 

 Peruvian pattern. It is rounded or ovoidal, with a high compressed occipital 

 region, with a quadrate outline viewed posteriorly, and an ovoidal outline 

 viewed above and laterally. The forehead recedes in a gentle curve from the 

 supra-orbital margins, and the supra-ciliary ridges are feebly developed. The 

 greatest height of the cranium is on a line with the anterior glenoid tubercle 

 and the centre of the sagittal suture. The biparietal diameter is 64 lines; the 

 antero-posterior, from the glabella to the occipital protuberance, 76 lines ; and 

 the height from the anterior margin of the occipital foramen to the centre of 

 the sagittal suture 64 lines. The breadth of the forehead at its narrowest part, 

 just above the external angular processes of the frontal bone, is 44 lines ; the 

 height of the latter bone from the root of the nose to its summit is 49 lines. 



Fragments of the other skulls indicate a larger size but the same form, 

 except larger superciliary ridges. A fragment of the face of one of them ex- 

 hibits the cheek bones prominent anteriorly, and the orbital and nasal orifices 

 large. 



The jaws are of moderate proportions and orthognathous. The teeth of all 

 three skulls are of the ordinary 'forms. Those of two of the skulls are much 

 worn. In one of the skulls some of the teeth had been lost during life, and the 

 alveoli obliterated. In a lower jaw containing an entire series of teeth but 

 little worn, the back two molars on one side present on the top of the crown a 

 small cavity, probably the result of caries. 



The remaining human bones consist of a few vertebra? with fragments of 

 others, fragments of two scapulae and innominata, a number of long bones of 

 the extremities, and a few small bones of the feet. 



The collection contains four humeri belonging to three skeletons. Two from 

 one of the larger skeletons measure 12 inches in length from the summit of the 

 head to the edge of the inner articular condyle, and 2 inches 10 lines in cir- 

 cumference, just below the deltoid insertion. A third humerus, apparently 

 from the same skeleton as the more perfect cranium before indicated, is of 

 more delicate form, II J inches in length, and 2 inches 8 lines in circumference 

 at the middle of the shaft. The fourth specimen, intermediate in proportions 

 to the others, has lost the head, and is peculiar from the very prominent sharp 

 angular character of the shaft internally. All the humeri present a small in- 

 tercommunication between the fossse above the ulnar trochlea. 



The bones of both fore-arms of a larger and smaller skeleton exhibit the 

 following measurements : larger ulna 1 inches long ; smaller one 9h inches : 

 larger radius 9} inches long; smaller one 8 inches 8 lines long. 



Of two femora from a larger and a smaller skeleton, both without the head 

 and condyles, one has measured about 17 inches in length, the other about 16J 

 inches. They are more bowed anteriorly than is usual, and both present a 

 greater degree of prominence of the linea aspera. 



Four tibia?, without the head, belong to the same skeletons as the femora. 

 The larger, when perfect, measured about 13 inches long from the front of 

 the head to the end of the inner malleolus; the smaller 13 inches. The former 

 present nothing peculiar, but the latter are remarkable for their laterally com- 

 pressed character; the antero-posterior diameter nf the middle of the shaft or 

 the breadth of the internal surface being 16 lines, while the transverse diame- 

 ter is but 9 lines. 



The stone implements found with the bones are six stone axes, of compressed 

 conical form, with a sharp trenchant basal border and a pointed apex.
