and three in the left and four in the right lambdoidal suture. There 

 is also a cluster of wormian bones at both right and left asterion. 

 The malo-maxillary and spheno-frontal sutures are synostosed. 



Processes. — Mastoids are small nipple-like projections, much 

 compressed from side to side. The styloids have been broken out. 

 Superior curved line and inion strongly developed for a female 

 skull. 



Muscular Impressions. — Not strongly marked except frontal por- 

 tion of superior temporal line and the region of the masseter of the 

 mandible. 



Lower Jaw. — Mandibular angle, 115 ; coronoid process sharp 

 and long; height of symphysis, 30 mm. 



NO. 40,608. — Cranium of adult female. The left zygomatic arch 

 is broken, as well as the lachrymals, turbinals, ethmoids and vomer. 

 The cranium is small, round and smooth. Cranial capacity, 1,170 cc. 

 All the molars of both jaws and the upper first premolars and second 

 incisors and lower right second premolar are in situ. The alveoli of 

 the other teeth are open. The teeth are not worn and are sound and 

 perfect. Dental index, 45. 



Norma Frontalis. — Forehead narrow and retreating, orbits rect- 

 angular, with infraorbital suture on right and left side. Nasal bones 

 of unequal size, broad and flat; nasal opening rounded, with diminu- 

 tive anterior nasal spine. Canine fossae not depressed. Malars flat- 

 tened and appressed. 



Norma Verticalis. — Ovoid outline sharply defined, with prominent 

 parietal eminences placed far back. Dish-like depression at lambda. 

 The bi-zygostephanic index can not be determined. 



Norma Posterior. — Pentagonal with longest dimensions at sides; 

 angle at vertex very slight. 



Norma Lateralis. — Frontal tubera not prominent. Marked facial 

 and alveolar prognathism. Glabella rounded but no trace of super- 

 ciliary ridges. Naso-frontal depression very slight. Pterion almost 

 in K. Zygoma (left) thin and delicate. 



Norma Inferior. — Foramen magnum diamond shaped, with con- 

 dyles very far forward; measures 32 x 28 mm. Deep condyloid fossa-. 

 Foramen spinosum and foramen ovale have a long, common slit-like 

 opening, with the apex of the petrosal for a posterior boundary. 



Sutures. — Exceedingly simple in region of bregma and pterion. 

 The sagittal and lambdoidal are somewhat complex. There is a 

 small wormian bone just below the left asterion, and several tiny 

 ossicles in the left lambdoidal suture.
