* A variety of Asaphus expansus remarkable for its projecting eyes. 

 Pander has suggested the new name of Asaphus cornutus for this variety 

 in his excellent work, Beitriige zur Geognosie, p. 137, pi. 7, figs. 5 and 6. 

 The name has been revived by De Verneuil in Murchison's Geol. Eussia 

 and the Ural Mts., vol. 1, p. 37*, figs. 1-4, in which he exhibits the transi- 

 tions in the length of the eye and the variations between Asaphus expansus 

 and A. cornutus.
