Upper Utica or Dekayella ulrichi Beds. 
This division of the Utica is exceedingly fossiliferous, but 
the fauna is mainly of a bryozoan character. Limestones, 
especially of a thin, slabby kind, are considerably more 
numerous than in the divisions below, two heavy layers being 
usually found at its bottom. Although. Dekayella ulrichi 
(Nicholson) occurs plentifully in the middle Utica, it is so 
very abundant in these beds that the name Dekayella ulrichi 
beds seems an appropriate faunal designation. ‘The thickness 
of this division is about sixty feet. TShe beds have been fre- 
quently exposed in grading for streets and other porposes,. so 
that the fauna i is fairly well known.
