The correlation of the beds in the Eastern border and Interior basins of N. America is Qiot yet satisfactorily accomplished. The period of the deposition of the millstone grit in |he interior basin may even possibly be synchronous, I am informed by Professor N. ^ Concerning the localities in the vicinity of Pittston, Mr. 'pL D. Lncoo, to whom 1 am indebted for all the specimens scribed from there, writes mo that the shale containing â¢toblattina Lesquereuzii was picked up hi the vicinity of Ittston, in a pile of culm or impurities from a mine; the t locality was unknown to him, but from the character the ^'.ate ho hod no doubt of its being from the roof shales the D seam of anthracite coal. LithomylacrU angustum id L, pittttonianum are from the roof shales of the E seam coal, which when unatTected by weathering much re- imhlo the shales of the D scam, but is very rarely so highly impregnated with carbon. The specimens came from Port GrifHth at the outcrop of the shales at one of the prin- cipal anticlinals that cross the otherwise quite level coal (iold, and on
