The most prominent difference between the specimens is in the 

 width of the upper jaw in front of the notch, just over the com- 

 mencement of the teeth-series ; but there does not occur any other 

 character in connexion with it. There is also a slight difference in 

 the form of the palate : in «, the central ridge is narrow and rounded 

 above behind ; in b it is broad, flat, sharp-edged, and very deeply 

 concave on the sides, under the edges, but the different specimens 

 vary in this particular. In d and g, the hinder part of the palate.
