lO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 64 



Late in 1906 a short memoir by Dr. Th. Lorenz appeared' in 

 which he described a number of new genera and species of Cambrian 

 fossils collected by him in the province of Shan-tung, and assigned 

 stratigraphic horizons to them. 



The fauna from Lai-wu was worked out of a single block found 

 loose in the bed of a brook about 9 km. west of Lai-wu. Lorenz 

 concludes that the fauna represents the time of the base of the 

 Swedish Andrarum limestone, within the limits of the zone with 

 Paradoxides davidis and P. forchhammeri': The list of species 

 given by him is as follows : 



Olenoides (Dorypyge) richthofeni Alokistocare sp. 



(Dames) Amphoton steinmanni n. g. and sp. 



Agnostus fallax laiwuensis ti. var. Ptychoparia {Soleno pleura) sp. 



Agnostiis parvifrons Linnarsson Hyolithes sp. 



Anomocare commune n. sp. Raphistoma broggeri Gronwall 



Anomocare ovatimi n. sp. Acrothclc bohemica (Barrande) 



From the descriptions and illustrations I have identified the above 

 as follows : 



Olenoides (Dorypyge) richthofeni 



(Dames) z= Dorypyge richthofeni Dames 



dgnostus fallax laiwuensis Lorenz ^Agnostus chinensis Dames 



Agnostus parvifrons Linnarsson ^Agnostus cf. parvifrons hinnarsson 



Anomocare commune Lorenz =Anomocarella chinensis Walcott 



Anomocare ovatum Lorenz ^Anomocare temenus Walcott 



Alokistocare sp. (not illustrated or de- 

 scribed) 



Amphoton steinmanni Lorenz = Dolichometopus deois Walcott 



Raphistoma broggeri Lorenz = Platyceras willisi Walcott 



Acrothele bohemica Barrande ^Acrothele matthewi eryx Walcott 



The horizon of the Dorypyge richthofeni fauna in Shan-tung was 

 definitely established by Messrs. Willis and Blackwelder as in the 

 Middle Cambrian below the central part of the Kiu-lung group.^ 

 In Shan-si the fauna occurs in an oolitic limestone that, by its fatina, 

 is related to the Ch'ang-hia oolite..*
