* 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, Beitrage zur Geognosie, p. 137, pi. 7, figs. 5 and 6. 

 The name has been revived by De Verneiiil 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 Amphns €xpa7isus 

 and ^4. cornutus.
