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

 Pander has suggested the new name of Asaj^hus coi'nutus for this variety 

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

 The name has been revived by DeVerneuil in Murchison's Geol. Kussia 

 aud 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 Asajjhns exp^ansus 

 and ^4. cornutus.
