 In this paper two widely sep- 

 arated Ordovician faunas are 

 described, one coming from the 

 Province of Shan-tung, the other 

 from eastern Ssi-ch'uan. The 

 first of these faunas consists of 

 poor material, the exact age of 

 which it is impossible to de- 

 termine. It is, however, re- 

 ferred to the Middle Ordo- 

 vician, or Mohawkian. The sec- 

 ond fauna is correlated without 

 much question with the Black 

 river of America on the one 

 hand, and the Vaginatus horizon 

 of Russia on the other. A de- 

 tailed description of fossils is 

 given, with figures, and com- 

 parisons are made with other 

 known Ordovician faunas of 

 eastern Asia. The material de- 

 scribed is the property of the 

 U. S. National Museum.

White, David — Continued. 



Resinous substances, in mi- 

 croscopical particles and as 

 lumps visible to the naked eye, 

 appear to be present in all, or 

 nearly all, coals of Mesozoic or 

 Tertiary age that have not been 

 subjected to such dynamic al- 

 teration as to cause the trans- 

 formation of the resins. This 

 transformation occurs when the 

 fixed carbon in the coals ap- 

 proaches 70 per cent pure coal 

 basis. The author describes 

 and illustrates resins and resi- 

 nous substances in Paleozoic 

 coals of a rather low bitumi- 

 nous rank, thus confirming the 

 Interpretations suggested by 

 various paleobotanists that some 

 of the secretory cells or canals 

 noted in petrified fragments of 

 certain Paleozoic plant types 

 may have contained resins.

 This paper contains descrip- 

 tions of the more characteristic 

 fossils of the Silui'ian forma- 

 tions mapped in the Eastport 

 folio of the U. S. Geological 

 Survey. Eight species are de- 

 scribed from the Edmunds 

 formation, and 12 from the 

 Pembroke. All of these are 

 illustrated and the types are in 

 the collections of the U. S. 

 National Museum.

 As the I'esult of a study of 

 the Upper Devonian faunas of 

 the Watklns Glen and Catatonk 

 quadrangles. New York, Profes- 

 V sor Williams made an interest- 



ing discovery of the recurrence 

 in beds of Portage and Chemung 

 age of fossils characteristic of 

 the Middle Devonian. This led 

 to an intensive study of the 

 faunas, the results of which 

 are given in the present paper.
