and irregularly quadrangular; teeth of median row smooth, not pitted; 

 unworn teeth of paired rows present shallow, apical depressions which 

 are distinctly wrinkled. 



The teeth of the splenial plate from Vanderpool, Texas (No. 7065, 

 see fig. 2, p. 446), correspond well in size and general appearance with 



those of the type- 

 specimen, while their 

 form and wear sur- 

 faces fit exactly those 

 of the vomerine 

 piece. There seems, 

 therefore, little doubt 

 that this specimen 

 pertains to the same 

 species as the latter. 

 This specimen pre- 

 sents several distinc- 

 tive characters. The teeth of the principal series are more than twice 

 as broad as long, and considerably exceed the combined ^v^dth of the 

 outer two rows, but the inner half of each tooth bends sharply down- 

 ward, so that only the outer half is opposed by the vomerine teeth; 

 there are apparently no teeth inside the principal row; those of the 



outer two rows are nearly equal 

 in size and but slightly broader 

 than long; the unworn tooth 

 of the outermost series has the 

 characteristically wrinkled 

 apical depression seen in the 

 vomerine teeth.
