specimens from Lincoln, Nebr,, being smaller and paler than typical 

 macTirinoides, while those from Vermilion, S. Dak., though large, are 

 distinctly paler than the typical form and have higher, more rounded 

 skulls. Two specimens from Carthage, Mo., and one from Winslow, 

 Ark., are" smaller than specimens from the type region, and have 

 smaller teeth and narrower rostra; the heavy mastoids and the 

 massive skulls are much as in maclirinoides. A series from Greenway, 

 Ark., shows a very slight approach toward S. a. pulcher in color and 

 width of rostrum, but is easily referable to maclirinoides.
