STRATIGRAPHY OF SHAN-TUNG. 39 
limestone, only 15 feet above the brown shale, which we regard as the 
top of the Man-t’o formation. This comprises: 
Globigerina? mantoensis Walcott Agraulos divi Walcott 
Micromitra pannula ophirensis Walcott Anomocare? butes Walcott 
Acrotreta pacifica Walcott Dolichometopus sp. undt. 
About 30 feet, 9 meters, higher, in the same section, a brownish, sandy 
limestone, rich in mica, yielded numerous specimens of a single brachiopod, 
Obolus obscurus Walcott. 
Another small lot comes from a horizon believed to be almost equivalent 
to the last, the locality being the mountain 3 miles northeast of Sin- 
t’ai-hién. Here four species of trilobites occur, some of them abundantly: 
Agraulos dirce Walcott Anomocare latelimbatum Dames 
Anomocare? butes Walcott Ptychoparia tolus Walcott 
As we go upward in the series, the next fossiliferous horizon is at 
the base of the dark cliff-making oolite, as exposed 3 miles, 5 kilometers, 
southwest of Yen-chuang. The layer is of variable thickness, but here

the base is 80 or go feet, 25 meters, above that of the Kiu-lung group. 
The stratum in which the specimens were found is a dark red limestone, 
only a few centimeters in thickness, and the remains are all fragmentary: 
Micromitra labradorica orientalis Walcott Anomocare decelus Walcott 
Agraulos abaris Walcott Anomocare minus Dames 
In a gray oolitic layer, lying immediately upon this red limestone 
and only a few feet higher in the series, a somewhat more comprehensive 
assemblage of forms occurred, but among them there is only one which 
appears also in the red layer below. The list includes: 
Obolus (Lingulella) damesi Walcott Agraulos dolon Walcott 
Obolus (Lingulepis) eros Walcott Ptychoparia titiana Walcott 
Agraulos abaris Walcott Ptychoparia (Liostracus) thraso Walcott 
We have no fossils from the remaining upper portion of what we have 
called the lowest limestone member. 
Fossils from the lower shale.—At the base of the lower shale-member 
fossils appear in great profusion, being especially well preserved in the
