THE CAMBRIAN FAUNAS. 7 
I have identified the above-listed fossils as follows: 
(a) Anomocare speciosum Lorenz ++++++++++5 = Anomocarella speciosa (Lorenz) 
Bathyuriscus asiaticus Worenz +++++++++- = Dolichometopus deois Walcott 
Agnostus fallax Linnarsson ++ +++++++++: =A. chinensis Dames 
Agnostus parvifrons latelimbatus Lorenz + + + -=A. latelimbatus (Lorenz) 
Acrothele granulata Linnarsson+++++++++> = Acrothele matthewi eryx Walcott 
(b) Teinistion (2) sp. seer reer reer eeees = Damesella cf. blackwelderi Walcott 
Drepanura (?) Sp. sve rere renee eee ees = Damesella cf. blackwelderi Walcott 
(c) Shantungia buchruckeri Lorenz ++++++++++ = Chuangia nitida Walcott 
Liostracus latus Worenz +++ +++ +e e reese = L. latus Lorenz 
By comparison with the sections of Messrs. Willis and Blackwelder 
fauna (a) is located in the lower portion of the Kiu-lung group at about the 
same horizon as the fauna from Lai-wu; fauna (b) represents the zone of 
Damesella blackweldert Walcott, which occurs in the central part of the Kiu- 
lung group; and fauna (c), or the upper fauna, may be assigned to the upper 
limestone of the Kiu-lung group, where the Upper Cambrian fauna is well 
developed.' 
At the locality of Tai-shan south of Tsi-nan Doctor Lorenz found frag- 
ments of a trilobite that he named Lzoparia blautoeides, which I have iden- 
tified as Anomocarella baucis Walcott, which occurs near the summit of the 
Upper Cambrian Ch’au-mi-tién limestone. 
At the locality of Tsing-tshou-fu he reports the following 
' Lioparia latelimbata (Dames) Obolella nitida n. sp.* 
Shantungia crassa n. g. and sp. Orthis sp. 
A not closely definable brachiopod Acrothele sp. 
My identification of the fauna is as follows: 
Lioparia latelimbata (Dames) Lorenz + -=Anomocare latelimbatum Dames 
Shantungia monkei Lorenz ++++++++s = Pagodia monkei (Lorenz) 
Obolella gracilis Lorenz++++++++++5 =cf. Obolus obscurus Walcott 
Orthis sp. and Acrothele sp. 
I do not find any statement of Doctor Lorenz that the species enumer- 
ated by him were found in association. They do not appear to have come 
from the same stratigraphic horizon. Pagodia monkei (Lorenz) is essentially 
an Upper Cambrian type, while Anomocare latelimbatum Dames is from the 
Middle Cambrian. 
I have not attempted to follow the classification of the trilobites given 
by Doctor Lorenz which is largely based on the division of the shell structure 
into non-porous (dense) and porous. ‘The mineralization of most of the speci- 
mens is such that it is often impracticable to determine with any degree of 
satisfaction whether the shell is non-porous (dense) or porous. 
By the courtesy of Dr. W. Deecke, of the Geological Institute of the 
University of Freiburg, I received eight pieces of the rock containing original
