This species is not fully typical of Tellerina because of the greater 

 w^idth of the fixigene at the anterior end of the eye lobe. However, 

 it seems undesirable to make a new genus for this species now. If 

 these specimens come from the Secret Canyon formation, this becomes 

 the oldest known species of Telleriim. 



Upper Cambrian, Secret Canyon ; (loc. 62) Canyon north of Adams 

 Hill, Eureka District, Nevada. 



Holotype.— U.S.N.M. no. 24565.
