Loomis — Neio Mink from the /Shell Heaps of Maine. 229 



The form is large and heavily built, the skull with a low 

 sagittal crest and short wide postorbital processes. The frontal 

 region is slightly arched between the orbits. The teeth are 

 those typical of the genus but rather stouter and heavier than 

 usual. The inner tubercle of the upper carnassial is single and 

 rather small. 



With this larger and typical form occur numerous individuals 

 about 20 per cent smaller, but otherwise with the same char- 

 acteristics, which I take to be the females, as there is in the 

 family usually about this difference in size between the sexes.
