This interesting little species peculiar in the compactness of its cephalic 

 parts pertains to a group represented by Ph. anceps Clarke of the 

 Decewville or uppermost Oriskany fauna of Cayuga, Ont.' Ph. brazi li- 

 en sis Clarke from the Maecurii sandstone of northern Brazil,^ and Ph. 

 nylanderi from Aroostook county, Me.^ 



Differences are observable in minor details in some of these widely 

 separated specimens but I detect none between those from the Becraft 

 mountain Oriskany described by me as Phacops correlator and the 

 cephala occurring in the Gaspe sandstone. This similarity extends to 

 details of structure and size. The figure given of the Oriskany specimen in 

 the work cited is misleading for the lobation of glabella is actually extremely 

 indistinct and more accurately expressed in the illustration here given.

A single specimen from the sandstones expresses the characteristic dor- 

 sal face of this species with elevated median portion separated from the 

 lateral longitudinal area by low depressions, the whole and more specially 

 the median portion being marked by concentric striae. On removal of the 

 exposed part the opposite face is found to be depressed convex or flat with 

 extended apertural margin. These features which indicate H. aclis 

 accompany the size usual to that species in its occurrence in the Hamilton 

 fauna of New York.

Tentaculites cartieri nov.

This is a large species with regularly annulated growth in early stages 

 only but with increase in size the annulations become variable and of
