The only fossils observed were a few fra^nents, probably plant 

 remains, L i o r li y n c h u s li m i t a r e and L u n n 1 i c a r - 

 diumfragile. 



Other exposures of the upper Marcellus shales have been noted 

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

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

 L i o r h y n c h u s I i m i t a r e 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 VlII. The polished section shows the corallites to 

 be sometimes of equal si2^ but more commonly large and some- 

 what rounded individuals are surrounded by others which are 

 smaller and more angular.
