quite sharply distinguished from the Grimes sandstones below 

 on account of their thinner bedding and bluish color. This divi- 

 sion is exposed in Italy hollow at the south end along Flint creek 

 and in the Italy gully, in the Naples valley in the Tannery gully 

 and Grimes gully. It is found on the south side of the road 

 leading easterly across Deyo basin, 2 miles south of Naples, 5 or 

 6 rods from the Ingleside road and near the foot of the hill. Here 

 it is an isolated exposure and its stratigraphic position can not 

 be ascertained with precision. It is however not far fmm 

 100 feet above the top of the Grimes sandstone. At this spot 

 it has produced a number of interesting fossils ; H y d n o - 

 ceras tuberosum, H. variabile, Ceratodictya 

 c i n c t a , Hysteracanthus, Spirifer mesacostalis, 

 Atrypa hystrix, Productella, Ambocoelia etc. The same 

 horizon is found near the residence of Charles S. Sutton on the 

 north side of the road leading from Naples to West hollow and 

 here also brachiopods are found. The same beds are seen on the 

 lands of the Pottle estate, 1^ miles north of the last named ex- 

 posure. One of the sandstones here contains fossils in great 

 abundance, principally of the same species as found in the 

 Deyo basin and on the West hollow road. A survival of the 

 Naples fauna is notable here in the presence of the species 

 Manticoceras oxy. In the road leading northward on 

 the top of Worden hill a ledge of sandstone is exposed on both 

 sides that contains masses of brachiopods. This locality is about 

 1 mile north of the south line of Bristol township. On Hatch 

 hill are outcrops in the lower part of the so called Three Cornered 

 clearing near the top. The rocks are also seen at the upper end 

 of the Hoecker and Lincoln gullies and on the hill north of the 

 Seaman schoolhouse, and in many small ravines on the sides of 

 High point. Frost hill and Gannett hill. They are also the sur- 

 face rock over the principal part of the town of Canadice to the 

 west of the sheet and extend over the tops of the ridges on both 

 sides of the Bristol valley for a mile or two into the town of 

 Bristol.
