III Manlius. 



The vicinity of Manlius has been and ever will continue to be 

 of great interest to the student of the Salina and Manlius stages. 

 Excellent exposures of the upper Salina may be found between 

 Green' Lakes and Manlius; and from traverse lines and 

 lines of level we have constructed the lower part of the section 

 given as No. 3, on Plate I. We call particular attention to this 

 section, not because of its direct bearing upon the question of 

 the development or extent of the Manlius fauna but to show 

 that here, as at Cayuga, the gypsum is both over- and under-lain 

 by Salina limestones. In other words the stratigraphy is perfect- 

 ly clear in this regard, whatever doubts one may have on the 

 subject, while studying the Cayuga section alone. 



The gypsum and Cobleskill beds are seen best to the south- 

 west of Manlius, while the layers above to the Onondaga are 

 best seen to the east and south. 



Two miles due north of Manlius, at an oblique four corners, 

 is a small cemetery, and in its vicinity are several interesting quar- 

 ries. Just west of the cemetry across the highwa)' anew digging 

 exposes light yellowish, gray, impure, shaly limestone layers pre- 

 sumably Rondout. The uppermost layers are replete with Spir- 

 ifer vanuxemi. In beds of the same appearance and in the 

 same horizon both in a quarry and in a small creek bed 

 south or southeasterly about T /z mile Eurypterus remains are 

 found abundantly in layers. 



Manlius. — 1 11 the quarry east of the cemetery, a great change 

 takes place towards the top of the outcrop. Sp. vanuxemi layers 

 of grayish blue give place to more crystalline, rough, brown- 

 weathering fossiliferous beds. From the cemetery, eastward to 

 the forks of the road }( mile by an abandoned old stone house, 

 these crystalline fossiliferous layers are well exposed, especially 

 in the field to the north. 



Stromatopora is seen here and there, and occasionally very 

 abundantly, especially in the uppermost layers of this deposit. 



Notwithstanding the apparent richness of the fauna of these 

 beds, little else is found in addition to what has already been 

 mentioned, except Stropheodonta varistriata , with occasional large 

 Megavibonia aviculoidea and a Meristella (l&visf). Still, Tenta- 

 cnliles, Beyrichia and Modiolopsis dubius have been collected from 

 this horizon and vicinity.
