This bed is specially noticeable in the hogback northeast of the 

 barn of Mr William Balmos. This is doubtless the locality where 

 Professor Mather and Dr Horton found trilobites so abundantly as 

 to suggest to them the name Trilobite mountain.^ It is also prob- 

 ably the place from which Dr S. T. Barrett described Dalman- 

 ites dentatus. 2 The bed maintains a uniform thickness of 4 

 to 6 inches wherever seen. It is always bounded above and below 

 by an inch of very arenaceous limestone. The included limestone is 

 almost entirely made up of fossil fragments, specially of Dal- 

 manites dentatus Barrett, Rensselaeria subglo- 

 bosa Weller and Chonostrophia jervisensis Schu- 

 chert. The following fossils were identified in the strata from K25 

 to K28 inclusive, along the hogback northeast of Mr William Bal- 

 mos's barn.
