Abstract
The type species of the eurekiid trilobite Corbinia Walcott, C. horatio Walcott, 1924, possesses very short palpebral lobes located opposite 2p glabellar lobe. The palpebral lobes of species of Eurekia Walcott and of Corbinia apopsis Winston and Nicholls, 1967, are considerably longer and located opposite 1p and 2p glabellar lobes. Corbinia is here restricted to the type species, and C. apopsis is assigned to Eurekia. Corbinia horatio occurs in the Basal Silty Member of the Survey Peak Formation of southern Alberta and appears to be confined to the lower part of the Eurekia apopsis Subzone of the Saukia Zone (basal Ibexian).This publication has 3 references indexed in Scilit:
