the Hamilton group and, unless they have a high range, which I am disposed 

 to believe, would bring the Hamilton and the Chemung groups together in 

 two or more localities. They are anomalies which further observations are 

 required to explain or remove." 1 Vanuxem's difficulty in reference to the 

 range of certain species in the vicinity of Port Crane and the bearing of the 

 above quotations will be appreciated after a description of the rocks exposed 

 near that village. At this locality the Chenango river makes a decided bend 

 to the west. On the eastern side of the river is a very steep hill and on the 

 western side a lower one. 



XLII A 1 . About a mile north of Port Crane exposures were found 

 from near the level of the canal extending for a considerable distance up the 

 hill. In the lowest rocks the following species were collected : 



1. Liorhynehus globuliformis, (Van.), Hall. 



2. (?) Lingula spatulata, Hall. 



3. Sphenotus rigidus (White and Whitfield), Hall (?). 



4. Nucula corbuliformis, Hall (?). 



5. (?) Goniophora, sp. 



In an old quarry near the village, C 1 , quite an extensive fauna was 

 secured, as is shown by the following list : 



1. Wiynclionella (Camarotoecliia) exi/mia, Hall. 



2. Spirifer, (?). 



See S. mesacostalis with middle septum ; H. S. W. 



3. Spirifer sculptilis, Hall (?). 



4. Spirifer granulosus (Con.), Hall and Clarke. 



5. Clwnetes setigera, Hall. 



6. Clionetes scitula, Hall (?). 



Wider forms than the common one, C. setigera, H. 



7. Ambocodia umbonata (Con.), Hall. 



Possibly this may be A. umbonata var. gregaria, H. 



8. Liopteria DeKayi, Hall (?). 



There are two specimens and they are doubtfully referred to 

 the above species. 



9. Liopteria, sp. (small specimen). 



10. Grammysia nodoeostata, Hall. 



11. Grammysia subarouata, Hall.
