HRDLICKA] PHYSICAL ANTHROPOLOGY OF THE LENAPE 49 
Anomalies.—The anomalies of the teeth are always of considerable 
interest, being mainly either reversive or degenerative (progressively) 
in character. The skulls observed indicate the following conditions: 
Male no. 285,301: A small supernumerary tooth between and on 
the labial side of the left lower second and third molars. The lateral 
upper incisors in this skull are somewhat abnormal lingually, their 
surface appearing as if rolled together from side to side, so that the 
tooth is cylindrical in form and its shovel-like hollow has become 
almost a cavity. 
In male no. 285,303: The third right upper molar is diminutive. 
In male no. 285,305: The third lower right molar is impacted, its 
vertical axis tending forward and upward. 
In male no. 285,326: The third right upper molar is diminutive. 
In female no. 285,305 is present the aforementioned fusion of the 
right lower lateral incisor and canine. The resultant tooth appears 
like a broad stout incisor (pl. 22). 
_In female no. 285,310: The crown of the right lower third molar 
is unusually large (13.5 mm. long by 12 mm. broad) and looks like 
that of a fused double tooth, but both first and second molars are 
present. The opposite tooth is also larger than ordinary, but the 
upper corresponding teeth are normal. 
Finally, in no. 285,311 the third right upper molar is rudimentary. 
Cuspids.—Many of the molars present were so worn that a deter- 
mination of their cuspid formule was impossible. The better pre- 
served teeth showed the interesting conditions detailed in the fol- 
lowing table:
