﻿63 Manlius T3 



In the railroad cut in the north-western part of the village of 

 Manlius we found a Zaphrentis, with Beyrichia barrctii ? and 

 Sp. vanuxemi in abundance. 



The cement strata, as well as the rough Stromatopbra beds, are 

 finely displayed in the quarries on the hill just north-east of Man- 

 lius. The cement and intermediate blue limestone layers 

 are of course to be classed as Manlius ; but the Stromatopora and 

 higher blue beds are less easily correlated. That the upper 10 

 ft., or the layers just beneath the Oriskany are Helderbergian 

 there can be no doubt, since luckily on the hill north-east of 

 Manlius they are often quite fossiliferous, though south-west 

 of the village we have found no exposures where beds in this 

 position carry Helderbergian remains. Manlius village, then 

 seems to be in the longitude of the extreme western extension of 

 the Helderbergian fauna. On the north-east hill, above referred 

 to, we note Stropheodonta planulata, very common ; Avicula 

 communis, common ; Meristella Levis, common ; Leptcena rhom- 

 boidalis, common ; a Rhynchonelloid form, cf. R. transversa, 

 common ; Dalmanella oblata and Sp. cyclopterus f rather rare. 

 It may also be remarked in psssing that the few inches of 

 Oriskany sandstone at this place contains a comparatively abund- 

 ant brachiopod fauna. 



Detailed sections about Manlius. — Nearly all the quarries north- 

 east of Manlius show beds down to and including the cement 

 rock. In one place only did we find the layers exposed for a 

 few feet immediately below. There is a quarry west of the road 

 and y 2 mile north of Manlius where about 4 ft. of blue "building 

 stone" are seen cropping out. In the fields below, the crystalline 

 brachiopod layers occur. What is shown on Plate I, Sect. No. 3, 

 down to the bottom of the "16" ft. layer may be taken for a de- 

 tailed section of what appears on the hills north and east of 

 Manlius.
