The only fossils observed were a few fragments, probably plant 

 remains, Liorhynchus limitare and L u n u 1 i c a r - 

 d i u m fragile. 



Other exposures of the upper Marcellus shales have been noted 

 on the banks of Cayuga creek. At Lake Gomo, above the level 

 of the dam, is a 5 foot layer of gray calcareous shale containing 

 Liorhynchus limitare as its most common fossil, and, 

 farther up the creek, at Van Duzee's farm, a 4 foot layer of 

 similar shale is exposed in the bed of the stream. It contains 

 Liorhynchus limitare, Strophalosia trun- 

 cata, Chonetes lepidus, etc. It thus appears that at 

 this locality also the fauna of the upper shales is typically Mar- 

 cellus in character and strongly contrasted with that of the 

 limestones below.

Two specimens only of this species were found. The individ- 

 uals are small and both represent the lower part of the coral. 

 They are well preserved, showing the septa and numerous dis- 

 sepiments. One specimen measures 13 mm in length, and 9 mm 



in diameter.

This coral occurs as thin, irregularly undulating expansions in 

 beds VI and VIII. The polished section shows the corallites to 

 be sometimes of equal size but more commonly large and some- 

 what rounded individuals are surrounded by others which are 

 smaller and more angular.
