ment as such, are at Kochester, Lockport, and Niagara, where available 

 formation names are exhausted. The largest fauna of this division is that 

 reported by Hall (3) from Eeynales Basin (also spelled Eeynolds, 2 : 71), 

 eight miles east of Lockport (10, map; 2: 63), and while we must go to 

 Lockport or the Eochester gorge for the typical section this name Eey- 

 nales automatically connotes a very definite faunule, including: 



Fungispongia irregularis Camarotoechia neglecta 



Favosites favosideus Ccelospira pUcatula 



Favosites hisingerif Fentamerus ohlongus 



Caninia Mlateralis {mareouif) StricMandinia canadensis (Can.) 



Cannapora junciformis Botryocrinus plumosus 



ITaly sites catenulariaf Ichthyocrinusf clintonensis 



Acanthoclema aspcritm Holopea ohsoleta 



Helopora frag His Iloifnotoma suhulata 



Phcenopora constellata Bucania stigmosa 



Ptilodictya {ohliqtia?) Oncoceras suhrectum 



Diamesopora tuhulosa Actinoccras vertehrattim 



Rhipidomella circulus Orthoceras virgulatum 



Rafinesquina corriigata Discosorus conoideus 



Strophonella patent a 8phyradoceragf ma^^i (unpublished) 



Platystrophia Iracliynota (2 : 71) Encrinurus ornatus 



Hyattidina congesta Goldius sp. nov. 

 Camarotoechia f bidens 



Also probably Glintonella vagahunda, Atrypina clintoni, Glorinda areyi, 

 Ptilograptus h artnageli. 



Westward the Eeynales limestone is persistent as a massive member to 

 the last exposure (12:316), but eastward it grades into shale, finally 

 indistinguishable in the sections from the Sodus shale above it. 



STERLING STATION IRON ORE 



Unfortunately this seems to be the only name available and unpreoc- 

 cupied for the 4-inch seam of ore 8 feet above the principal ore bed ( Fur- 

 nace ville) at Sterling Station (9 : 57) which is not known to outcrop 

 elsewhere, but appears in several wells. Fossils unknown to the writer. 



S0DU8 SHALE 



Hartnagel, 1907 (8:13), emended. Hartnagel defined this name as 

 from the town of Sodus, ^Vhere this division is well shown in the vicinity 

 of Sodus bay" ; but, misled by Hall's error, he extended it to the basal or 

 Maplewood shale at Eochester. Near the mouth of Salmon Creek, nearly 

 two miles west of Sodus Bay, Hall reports the lower members of the 

 Clinton group (2 : 66, 42), but the basal shale must there be very thin

12 "At Cental's mill, near Sodus Bay, . , . the green shale below [the Reynales] is 

 but two or three feet thick" (Hall: Ann. Rept. for 183», p. 328).
