Plate 6, figure 5; plate 7, figure 5 ; plate 8, figure 3 Mr Hartnagel while engaged on an investigation of the iron ores of the Clinton formation obtained in the ferruginous shale that directly over- lies the ore a few small but finely preserved fragments of a graptolite that is apparently closely related to P . a n a s t o- m o t i c a. Later collections have shown this form to be not uncommon above the lower iron ore bed at Clinton, N. Y. The main difference is one of relative dimen- sions, the Clinton form having narrower branches (.4 mm-1 mm, mostly only about .5 mm) and smaller meshes (five to seven in 10 mm transversely and three to four longitudinally). The meshes are also relatively wider and Fig. 104 Palaeodictyota clin- tonensis sp. nov.

Gurley makes the following remarks : I am indebted to Prof. Edward Orton for the loan of the type specimen of this species. After careful comparison with it of Hall's description and figure I can not find that either leaves much to be desired. Only one cor- rection should be made. The strongest branches reach a width of 1 mm ( inch)
