length are compared together, the distance from the postorbital fora- 

 men to the extremity of the nasal bones in the former is found to be 

 considerably less than in the latter, while the distance from the 

 postorbital foramen to the supraoccipital crest is much greater ; the 

 zygomatic arches in Ft. loocJiooensis are also less curved outwards, 

 and there is no ascending process ; dentition nearly similar in both, 

 but in this species the canine is separated by a greater interval from 

 the second premolar, and the last upper molar is larger, being equal 

 to, if not larger than, the first lower premolar ; the last lower molar 

 is smaller than the first premolar, but larger than one of the outer 

 lower incisors.
