SKELETAL REMAINS 77 



right side in the lower jaw may be noted the absence of one incisor, due 

 apparently to nondevelopinent ; on the left there are two incisors, both small. 

 The third molars, now absent, must have been small : their cavities show a 

 single root of rather submedium proportions.

SKULL NO. Z 



A very defective adult specimen, found in Gilder mound, by Mr. Gilder, at a 

 depth of about 3 feet; sex uncertain, though probably female; color dirty 

 yellowish, ventrally and to a slight extent dorsally with spots of blackish dis 

 coloration ; no fossilization, no aspect of great antiquity ; cranium of good size, 

 normal ; shape oblong, contours rounded, outline of posterior plane approaching 

 pentagonal ; supraorbital ridges above medium feminine, or submedium mascu 

 line, limited to median half of each supraorbital space. Forehead low but 

 vault-bend distinct (above the bend the bone slopes backward) ; diameter 

 maximum (along coronal suture), approximately 11.0 cm., nasion-bregma arc 

 12.7 cm. No sagittal ridge. Thickness of left parietal 3 to 5 mm. Sutures 

 (coronal, sagittal) patent, serration fair. No brain impressions ventrally. 



SKULL NO. 3 



A good-sized adult female cranium (defective) showing a slight asymmetry, 

 otherwise normal. Discovered by Mr. Gilder in the mound now named after 

 him ; exact depth of find uncertain, but probably not more than 4 feet. Color 

 pale dirty yellowish ; no fossilization has the appearance of a fairly recent 

 specimen. Was apparently dolichocephalic ; greatest length 18.9 or 19 cm. 



The contours of the skull are but little angular. The supraorbital ridges are 

 of about medium feminine size. The forehead is of moderate height and fairly 

 good vaulting ; the right side is somewhat more prominent than the left. 

 Diameter frontal minimum 8.6, frontal maximum 11.1 cm., nasion-bregma arc 

 12.1. There is scarcely any sagittal elevation. The temporal ridges are but 

 slightly marked and are distant from the median line. The glenoid foss;e are 

 deep. A slight dehiscence. such as occurs quite frequently in the Indian, is 

 seen in the floor of the left auditory meatus. All the remaining sutures are 

 patent, serration submedium. Thickness of left parietal 4 to 5 mm. 



SKULL NO. 4 



Only the frontal and parts of the parietals remain. Found &quot;deep&quot; (though 

 less than (&amp;gt; feet from the surface) in the mound by Mr. Gilder. It is appar 

 ently a good-sized adult normal male skull. Color dirty yellowish, with some
