Of this form but one specimen has come to hand. It differs from that referred 

 to Ps. Jcansasennis chiefly in being more convex and in having its stride persistently 

 and regularly unequal, and from Ps. hawni in having them finer and with much less 

 disparity between the coarser and the finer ones. The .species to which this .speci- 

 men belongs seems to be closely related to, if not identical with, Beede's Pseudo- 

 inonotis Imwni-Y&Y. equistriata. 



Locality and horizon. — San Jukn region (station 2342); Rico formation.
