SECTIONS NEAR GALLUPVILLE, 



To tlie south of Gallupville and the Foxkill is a high hill known 

 as Mt Sagerwana, on which are various excellent exposures of the 

 different formations; but unfortunately an accurate section has 

 not been made of the hill, and the time spent in this study would 

 well repay one. 



X B 2 In the Beekman quarry south of Gallupville, to the east 

 of the Mt Sagerwana road, is a good exposure of the Pentamerus 

 limestone, which was formerly quarried and burned for lime. The 

 rock is very fossiliferous, and it is an excellent place for collect- 

 ing. In a comparatively short time the following species were 

 obtained from this excavation. 



1 Sieberella galeatus (Dal) H. & C. (aa) 



2 Atrypa reticularis (Lin.) Dal. (c) 



3 Spirifer perlamellosus Hall (r) 



4 Stropheodonta varistriata (Con.) Hall (c) 



5 Strophonella punctulifera (Con.) Hall (aa) 



6 Uncinulus mutabilis (Hall) H. & C. (c) 



7 Lichenalia torta Hall (rr) 



8 Dalmanites micrurus (Green) Hall (rr) 



9 Dalmanites pleuropteryx (Green) Hall (r) 



10 Spirifer vanuxemi (Van.) Hall (r) 



11 Loxonema fitchi Hall (?) (r) 

 About 170 feet higher than the Beekman quarry is a massive 



ledge of light gray, fossiliferous limestone, which shows on the 

 Mt Sagerwana road and is also well exposed in the brook imme- 

 diately west of the road. This is the Becraft limestone. The 

 following species were collected at this locality: 



1 Spirifer concinnus Hall , (c) 



2 Camarotoechia ventricosa (Hall) H. & C. (c) 



3 Meristella princeps Hall (c) 



4 Atrypa reticularis (Lin.) Dal. (c) 



5 Rhynchonella (Uncinulus) campbellana Hall (rr) 



6 Orthis sp.
