fdnkhouser] ARCHAEOLOGICAL SURVEY OF NORRIS BASIN 231 



of age with the following measurements : Maximum length, 148 mm ; 

 glabella-inion length, 133 mm ; height, 112 mm ; nasal length, 33 mm ; 

 length of orbit, 29 mm ; breadth of orbit, 28 mm ; sagittal-cranial arc, 

 322 mm ; bigonial breadth, 69 mm ; length of ramus, 29 mm ; breadth 

 of ramus, 20 mm. The first permanent molars have not yet erupted. 



/Skeleton No. 7. — Fragmentary skull of an adult, probably male, giv- 

 ing the following measurements: Maximum length, 194 mm; maxi- 

 mum breadth, 135 mm ; cephalic index, 69 ; glabella-inion length, 168 

 mm; breadth of ramus, 35 mm. Other parts of the skeleton are not 

 satisfactory for study. 



Skeleton No. 8. — The skeleton of an adult male in an excellent 

 state of preservation. Skull : Maximum length, 165 mm ; maximum 

 breadth, 141 mm ; cephalic index, 85 ; glabella-inion length, 159 mm ; 

 height, 146 mm; length of orbit, 37 mm; breadth of orbit, 35 mm; 

 breadth of occipital foramen, 25 mm; bigonial breadth, 110 mm; 

 breadth of bicondylar, 118 mm ; length of ramus, 49 mm ; breadth of 

 ramus, 34 mm. Long bones : Eight humerus, 277 mm ; left humerus, 

 276 mm; right ulna, 228 mm; left ulna, 224 mm; right radius, 212 

 mm ; left radius, 215 mm ; right femur, 396 mm ; left femur, 395 mm ; 

 right tibia, 328 mm ; left tibia, 325 mm ; left fibula, 311 mm. 



The averages for the osteological measurements of the five skeletons 

 from Site No. 15 are as follows: Cephalic index, 85; glabella-inion 

 length, 150.28 mm ; height, 129.40 mm ; sagittal-cranial arc, 342 mm ; 

 circumference, 499.33 mm; bigonial breadth, 91.5 mm; bicondylar 

 breadth, 110.5 mm; length of ramus, 45.66 mm; breadth of ramus, 

 29.71 mm. Right humerus, 298.33 mm; left humerus, 293.33 mm; 

 right ulna, 236.66 mm ; left ulna, 234.66 mm ; right radius, 214 mm ; 

 left radius, 213 mm ; right femur, 421 mm ; left femur, 420 mm ; right 

 tibia, 341.66 mm; left tibia, 339.33 mm; right fibula, 333 mm; left 

 fibula, 336 mm. The above figures probably represent good skeletal 

 averages for the region under consideration, since the skeletons seem 

 to be normal, typical, and in good condition. 



Site No. 16 



Only two fragmentary skeletons were available from this site and 

 neither of these yielded enough material to be of importance. The 

 only measurements which can be recorded are as follows : 



Skeleton No. 10. — Skull: Maximum length, 182 mm; maximum 

 breadth, 130 mm; cephalic index, 71.4; glabella-inion length, 173 

 mm ; nasal length, 50 mm ; sagittal-cranial arc, 312 mm. 



Skeleton No. 11±. — Fragmentary adult skull of which no measure- 

 ments are possible except that of the bigonial breadth of the lower 

 jaw which is 114 mm. The right femur is 492 mm long; the left 

 humerus measures 343 mm ; left radius, 265 mm ; left femur, 494 mm.
