Dentition :^ • ^ or 



J wx q' pm. -^, m. g. Upper premolars square. 

 Lower pm. 2 small (pm. 1 absent above and below), pm. 3 & 4 

 elongate. Ail molars elongate, especially the second. Lower 

 border of lower jaw unusually flat : one mental foramen. Jaw in 

 section rather flat outside and sh'ghtly convex inside. Moderate 

 diastema in front of anterior lower premolar. There is thus a 

 mixture of various generic characters, the balance, perhans, 

 favouring a general resemblance to Moropus. The foiin is at 

 present insnflaciently known, but there is enough to warrant the 

 retention of Dr. Pilgrim's genei-ic name until further material is 

 discovered.
