tocardia speciosa and Cho7ietes lepida. A single small specimen 

 of Spirifer resembling S. mesastrialis was found at this station. 



Station 2. — About Yz mile south of Statioji z, at the side of 



the railroad, the following species were found: Lunulicardium 



fragile, Glyptocardia speciosa, Goniatites siniiosus, Chonetes lepida, 



Coleolus aciculmn, Strophodo7ita nmcronata, Cladochonus sp., Lin- 



gula spatulata, Paltsoyieilo emarginata. 



The occurrence of Strophodonta nnia^onata here in the lower 

 Portage fauna is of special interest since it is a very abundant 

 fossil in the Ithaca group. 



Station j. — A short distance south of Station 2, at the side of 

 the railroad, the following species have been obtained in the 

 Portage shales: Cladochonus s^., Strophodonta mucronata, Nuculi- 

 tes oblongus, Amboccelia ti^nbonata, Chonetes lepida, Plenrotomaria 

 sp. , Palcsoneilo constricla, P.filosa, Glyptocardia speciosa, Coleolus 

 acicuhim, Lunulicardium fy^agile, Leptodesma social e? , Goiiiatites 

 discoideus, G. sinuosus, Loxonema sp. , crinoid stems. 



Station 4.. — In the north glen at McKinney's station, 20 feet 

 above the lake. 



In the tough arenaceous sandstone at this horizon, a second 

 zone of Spirifer Icevis has been discovered. The associated fau- 

 na of 5. Icevis at this horizon appears to be much less abundant 

 than that of the upper zone. The only other species identified 

 are Strophodonta ^nucronata, a species of Macrodon, and Goniatites 

 simtosus. The upper S. Icevis bed in this secftion lies no feet 

 higher. 



Station 5. — 35 feet above Station 4. and 85 feet below the 

 upper Spirifer Icevis bed, the following species were obtained: 

 Glyptocardia speciosa, Rhynchonella pugnus, Coleolus aciculmn, 

 AHinopteria boydif, Goniatites s^., Leda diver sa, Grammy sia sp?, 

 Mytilarca chemungensis, Lunulicardium fragile? 



The discovery of Rhynchonella pugmts at this station extends 

 its vertical range in this region from a limited zone in the Ith- 

 aca group into the middle Portage, about 100 feet below the base 

 of the Ithaca group. 



Station 6. — The shelly sandstone and silicious shale at this sta- 

 tion which is 75 feet above the lake and 65 feet below the up- 

 per Spirifer Icevis zone, contain an abundance of Glyptocardia 

 speciosa and Lumilicardium fragile; associated with these are 

 Strophodonta mucronata, Palceoneilo flosa, Nucula dijfide7is, Goni-
