PRossER.|  Cretaceous.—Comanche Series of Kansas. 181 
From the hills south of the Smoky Hill river, three and one half 
miles east and one half mile south of Lindsborg, Mr. Beede collected 
specimens of brownish, arenaceous shales containing Twrritella, 
that resemble the Mentor more closely than the Kiowa. 
In the eastern part of McPherson county, on section 23, Delmore 
township, Mr. C. N. Gould found numerous specimens of the shaly, 
Ostrea limestone of the Kiowa. Later, this locality, which is on 
Mr. Stark’s farm, four miles south of the Twin hills, was visited by 
the writer. The pieces of shaly limestone are loose near the top of 
a small ridge between Gypsum creek and a western branch. None 
of the shales were found in place, though there is no doubt but 
that they once formed a part of the hill. On the ridge east of 
Gypsum creek, at this locality, is a ledge of light gray quartzitic 
sandstone, similar to that on the highway between sections 24 and 
25 Bonaville township. Some of the sandstone shows irregular 
bedding and it is apparently near the base of the Dakota formation. 
The farthest north the Kiowa shales are known is in Saline 
county on the hill east of the Smoky Hill river. This locality is on 
the southwest corner section 27 and southeast corner section 28 
Walnut township where, at least, a foot of the shaly Ostrea lime- 
stone is clearly exposed along the highway. Above is brownish 
Sandstone containing Mentor fossils. In the field to the west are 
numerous blocks of the Kiowa Ostrea limestone. The fossiliferous 
Shales of this locality were first noticed by Prof. A. W. Jones of 
Salina who wrote me in regard to it. ‘The Kiowa shales where 
exposed in McPherson and Saline counties consist of the calcareous 
Shales to shaly limestones, which in southern Kansas are found in 
the upper part of the formation. Apparently, the black, argillaceous 
shales that form the lower part of the formation in southern Kansas 
do not occur in central Kansas.
