42 RESEARCH IN CHINA. 
About 200 feet, 60 meters, higher, in the same series, Damesella black- 
welderi was found in some numbers. 
The only horizon in which fossils seem to be plentiful is 50 to 75 feet, 
15 to 23 meters, below the top of the member. At this horizon a granu- 
lar gray limestone contains a varied fauna, which is allied, by the presence 
of three species in both regions, to that from the upper portion of the 
Ch’au-mi-tién limestone in the type locality. This fauna includes: 
Orthis (Plectorthis) doris Walcott Dikelocephalus? baubo Walcott 
Orthis (Plectorthis) linnarssont Kayser Ptychaspis cacus Walcott 
Orthis (Plectorthis) kaysert Walcott Ptychaspis callisto Walcott 
Syntrophia orrentalis Walcott Ptychas pis calyce Walcott 
Hyolithes daphnis Walcott Ptychaspis ceto Walcott 
Orthotheca cyrene Walcott Ptychoparia batia Walcott 
Anomocare? bianos Walcott Solenopleura beroe Walcott 
A single small and imperfect specimen of Orthoceras sp. was discovered 
in the uppermost layers of the Ch’au-mi-tién limestone near Yen-chuang. 
The presence of this genus indicates close approximation of the Ch’au-mi- 
tién to the Ordovician. 
VICINITY OF T’AI-AN-FU. 
Scattered exposures of the Kiu-lung strata were examined during our 
journey along the main road from Ch’ang-hia to Sin-t’ai and thence to 
Po-shan. Some of these show individual peculiarities worthy of mention, 
About 1 mile, 1.5 kilometers, west of the city of T’ai-an-fu, the hill 
marked by a small pagoda is composed entirely of the lower limestones of 
the Ch’au-mi-tién formation. The hill is surrounded by a broad plain 
of alluvial material, and is thus cut off from the granitic exposures north 
of it. On this account stratigraphic connections were not visible, but 
fossiliferous layers in the limestone furnished an ample array of species 
for the purpose of correlating the strata with the proper horizons in other 
districts. From strata 20 to 30 feet, 6 to 9 meters, below the top of the 
hill we secured fossils whose nearest allies are those from the lower part 
of the Ch’au-mi-tién limestone, both in the type locality and in the region 
east of T’ai-an-fu as well. ‘The list of species from this pagoda hill includes: 
Obolus matinalis Hall Illenurus canens Walcott 
Obolus (Westonia) sp. undt. Illenurus dictys Walcott 
Orthis (Plectorthis) pagoda Walcott Menocephalus? depressus Walcott 
Syntrophia orientalis Walcott Pagodia bia Walcott
