Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. Lochman 1952 | This species appears to differ from all described ones in (i) the gentle expansion and low convexity of the front of the glabella, and (2) the narrow, descending border of the pygidium. In fact, only two other species show a similar narrow border - G. helesis (Walcott), preserved in shale, and with the border apparently horizontal in position, and the paratype U.S.N.M.No.62695 of G.mckeei Resser. On this specimenal so the narrow border apparently lies in horizontal position and so is not comparable to the Mexican species. Attention should be called to the fact that the holotype of G.mckeei has a pygidial border of medium width and so could not represent the same species as the above-mentioned paratype. |
