is restricted to the Early Ordovicic section of the Franklin, Caballos 
and Mimbres ranges. 
Epicene Series, Keyes. (Proc. Iowa Acad. Sci., Vol. XXI, p. 186,

Frederickstiirg Limestones, White. (Proc. Acad. Nat. Sci., Phila- 
delphia, 1887, p. 40, 1887.) Part of Cretacic section well exposed in the 
Sierra de los Muleros west of El Paso. 
Frondosa Limestones., Main body of Mid Ordovicic series in Frank- 
lin mountains, which carries a Galena-Trenton fauna. 
Fusselmann Limestones, Richardson. (Am. Jour. Sci. (4), Vol. XXV,
