306 REPORT ON THE STATE CABINET. 



of D'Oebignt for the 2\ concentrica ; and Merista of Suess for the T. tumida, 

 herculea, etc. I shall also follow Prof. King and Prof. Woodward in placing 

 those shells which have a punctate test, such as the T. ferita, adrieni, se7-pen(ma, 

 etc., in the subgenus Eetzia of Kiug, although, at the same time, it does uot appear 

 to me that the characteristics and tendencies of these latter sufficiently demon- 

 strate the necessity of separating them from the group of T. concentrica 

 (Athteis, M'Cot)."
