is near 225 feet and may be 250 ft. The lower third of the Coeymans may be called the Illionia zone (130 to 40) the middle the Grimidal zone (about 100 ft.) and the upper third the hspidula zone (about 30 feet). Stromatopora occur throughout the Coy- man but are most abundant in the hspidi- dula zone, less common in the Grimidal zone and rarest in the Illionia zone. Lepadocrinus as stems are very common in the middle zone but good specimens appear to occur only in the Stromocrinus bed. In 1904 I noticed that the upper corner else is probably all transitional zone between Coeymans and New Scotland. Some several Favosids (F. hildubryia?), among others P. foliatum, E. media, E. singulans (Orisk. form), Orthothete orthanthus, Uncinulus mutabilis,
