Couling from the neighliorhood of Tsingchou-Fu, Kiaochow, Shantung. Crick however 

 did not identify his specimens specificalh^ referring to one as closely allied to Adinoceras 

 (Ormoceras) tenvAfihi.ia Hall from the Black River formation of New York, and to another 

 as possildy representing the genus Gonioceras, a reference which now appears to he pro- 

 hahlv correct. Besides the cephalopods, Crick mentioned the occurrence of several small 

 hrachiopods. According to Buckman " the general appearance suggests OrtJiis {Dalma- 

 nella) trstudtnarid Dalman, an Ordovician species"*). This is the first published 

 demonstration of tlie Ordovician age of these limestone in north China. In I'.HJIj Th. 

 Lorenz ** described the following species from the Ordovician of Shantung the first three 

 from Ho-shan the fourth from Santefan. 



1. Ax(ii>Jiii,>< ho'Jiml Lorenz. 3. HijolitliCA sp. 



2. Marl mm logani Salter. 4. Pkdamhonites sericms (Sowerby). 



Freeh (in Richthofen V p. 14) referred the first three of these to the Middle 

 Ordovician the fourth to the Upper Ordovician. 



In their investigations of the geology of parts of northern China which appeared 

 before Freeh's monograph, Bailey Willis and EUiott Blackwelder (in 1903-1904) recog- 

 nized that the greater part of von Richthofen's Kolilcnkalk was to be referred to the 

 Ordovician. Professor Stuart \\'eller^ of the University of Chicago, who studied the 

 fossils collected by Blackweldor, recognized the existence of tlie cephalopod genus 

 Orthoceras, the gastropods iLtchuru? or IfcUcotanKn'iMjd L(ri>]inspira, the trilobite AsapJiusf, 

 and the hrachiopods SfropJiomeud and Ortlii^ (Dnlmnin-Ua?) in the Ordovician rocks of 

 Sliantung lait he \\;ts unable to make specific determinations because of the poor state of 

 preservation of the fossils. He however descril>ed a number of species collected l)y 

 Black^v■elder in tlie Yangtze region (south Cliina) *'"* and recognized their affinities with 

 European Mid<lle Ordovician sjn'oies. Pj-eviously, several authors had described Ordovi- 

 cian fossils from south China among them S. P. A\'oodward (1S,3(;) Kingsmill (180!)) and 

 Grieve (Pss?). The first described the A\-en-known "Pagoda stone" as Orthoceras 

 sp. and this A\'as later redescribed by Foord as OrlJtoccrax cldncnse Foord (ISSS). Kayser 

 and Freeh also descriljed a nuail»cr of Ordovician sjiecies from southern China, (v. 

 Richthofen Vob. IV and \") an<l a numl>er of these have since l»een redescribed with 

 others by H. Yabe and I. PLt.vasaka in tlieir Avork " Pakeontology of South China" 

 (1920). Several Ordovician species from south China were also described and recorded
