l 



almost any layer, though it is rare in the upper part, L, to P. 

 Good enrolled specimens were obtained from the Bellerophon 

 zone, on the east side of the creek, and from the first Platystrophia 

 zone, on the west side. 



Ceraurus pleurexanthemus. — Very rare in the lower part and, 

 though not common, occurs in almost every zone above E. 



The Faunas op the Basal Trenton in the Valley 

 of West Canada Creek. 



From the section at Trenton Falls one turns naturally to the 

 sections near Newport on West Canada Creek, where the lower 

 Trenton, lacking at the type section, is well exposed. Both 

 Theodore G. White, 1896, and Prosser and Cumings have 

 described the lithological character of the beds at this place, but 

 neither give the fauna of the lower limestone, though the latter 

 mention the occurrence of fossils in the Birdseye and list the 

 following species : 



Phytopsis tubulosa Hall, Murchisonia cf. varicosa Hall, Ortho- 

 ceras midticameratum Con., Modiolopsis sp., Rafinesquina alternata 

 (Con.) Hall and Clarke, Leperditia sp., Stictopora sp. , and a 

 gastropod.* 



There are three localities in the vicinity at which Birdseye 

 fossils are common. One is in a ledge in the bank of the creek 

 near the railroad-cut about half way between Newport and 

 Poland. The second is in a quarry a short distance west of the 

 railroad station at Newport. The third is in the smaller quarry 

 at the Moshier workings. This is the one described in this 

 paper, and was selected because the fossils were better preserved 

 than those collected at the river bank, and the section is more 

 complete than that near the Newport station.
