XLII D l . On the hillside west of the Chenango river, opposite Port 

 C rane, is an old quarry that was opened during the construction of the 

 Chenango canal. It is in the eastern part of Chenango township, and the 

 bottom is some seventy -five or more feet above the river. The wall of the 

 quarry shows fifteen feet of bluish shales and shaly sandstones that weather 

 to an olive color. Some of the thin sandstones and slightly calcareous layers 

 contain fossils abundantly, especially RhynchoTiella (Vamarotcechia) Stevensi, 

 Hall, and Tropidohptu* rarinatu.? (Con.), Hall. The species in the list were 

 gathered in one half hour : 



1. Tropid-ohptux carina! us (Con.), Hall. (aa) 



Typical specimens of this species such as occur in the Hamilton. 



2. MhyrwhcmsUa {Camarotcechia ) StevenM (H.), Hall and Clarke (?). (aa) 



The ventral valves of a number of specimens show clearly the 

 dental lamellae described in this species, and the dorsal valves, the 

 septum about one-third the length of the shell. However, the 

 plications are less than given for this species, and in form many of 

 them are about the same as R. eximia with which they must be 

 compared. 



3. Chonetes scitula, Hall. (rr) 



One specimen shows over fifty striae and is clearly of the form 

 of this species. 



•4. Orthonota (?) pa/rvula, Hall. (r) 



5. Microdon ( ( 'upricardella) //regariu.?, Hall. (c) 



6. Palceoneilo plana, Hall (?). (rr) 



7. Gouiophora, cf. Oh£mungensis, (Van.), HalL (rr) 



8. Gramin ijsia clUptica, Hall (0- (it) 



Imperfectly preserved. 



!). Gra/mmysia circular/.?, Hall. (rr) 

 The posterior portion of the shell is not complete, but in all the 

 characters preserved it agrees well with this species. 



1 0. Ormoid stems and segments. (c) 



11. IAopteria DeKaiji, Hall (?). (c) 



The specimens resemble quite closely Hgnre 6, plate LXXXVI1 1 

 (Pal., N. Y.h which is a large specimen from Schoharie county.
