This approaches E. flivaricatum Lund, (in Nova Afta R. Soc. Scient.

 broader apex with a very shallow notch, its trilobed median wart, in 

 the two quadrigranulate warts within the apex, and in the trigranulate 

 wart within each basal angle, which latter feature causes the vertical 

 view to be rectangular-oblong.
