Level of Otego ereek at Mt. Vision. 



XXIV J>\ About three-quarters of a mile south of Mt. Vision, <»n the 

 eastern side of Otego creek, is a rocky hillside on the Field farm, known 

 locally as the "Owl Patch. 1 ' A short distance farther south, the point of the 

 hill strikes the highway about seventy-five feet above the creek level, and 

 thin, argillaceous, quite fossiliferous shales of bluish or olive color with thin 

 strata, of sandstone are quite well exposed by the roadside. The following 

 species were obtained : 



1. Spirifer mucronatas (Con.), Bill. (c) 



2. Atrt/pa reticularis (Linne), Dal. (it) 



3. Goniophora Hamiltonmsis (Hall), Miller. (rr) 



4. Nuculitex ohloixjatHs,, Con. (rr) 



5. Platyceras, sp. 



XXI V B 2 . Seventy-five feet higher on the hillside, in the "Ow l Patch," 

 are conspicuous ledges of coarse, arenaceous shales, in lithologic character and 

 fauna similar to those of the lower ledges ( XXIV C 1 ) of Mt. Vision. This 

 outcrop belongs in the Hamilton formation, and the fossils are abundant and 

 typical, as will be seen below: 



1. Spirifer mucroTiatus (Con.), Bill. (c) 



2. Trqpidoleptus carinatus (Con.), Hall. (r) 

 •">. Spirifer 'full! us, Hall. (c) 



4. Tellvnopsis subemarginata (Con.), Hall. (rr) 



5. Microdon (GypricardeUd) tenuistriatus, Hall. (a) 



These specimens arc smaller than the figures of this species and 

 perhaps are the forms of M. bellistriatus, Con., which bave tine 

 striae, hut they agree with the description of the young forms of 

 .)/. t< nuistriatus, Hall. 

 (1. Nucula corhidiforinix, Hall. (it) 

 7. Grwmmy sia arcuata (Con.), Hall. (rr)
