CRANIA FROM THE MOUNDS OF FLORIDA. 



psedbmorphie form of choana? is almost equal to the wide-based form, thus markedly 

 differing from both Seminole and Santa Barbara varieties. — The foramen laeerum . 

 medium was closed in 7 and open in 18 examples. — The sphenoido-tympanic suture 

 was not overlapped by the spinous process in 12 (quite one-half), both of the above 

 furnished good characters when compared with those of the other series. — The 

 malar bone lacked the suture-trace in 7 examples as against nil of the other groups. 

 The bone enters the spheno-maxillary fissure in all but 6, and the marginal process 

 was large in 9. — The temporal ridge was interrupted in about half the specimens 

 and the lambdoidal suture was harmonic near asterion in 17, a much larger propor- 

 tion than in the Santa Barbara skulls, but about the same as in the Florida. — The 

 average width of the sconce is the lowest of the series, being but 56 ; the maximum 

 150 and the minimum 94. — An unusually large number (12) of the lachrymal bones 

 effect a junction between the hamular process and the maxilla. This is a character 

 of reversion to many lower primatean genera, The seven examples retaining entire 

 lachrymal bones showed an average measurement of 16 mm, long by 9 mm. wide. 

 — The third molar of the lower jaw was in advance of the base of the coronoid 

 process in four bones examined. The mental foramen was not in advance of the 

 second premolar in a single instance.
