In the chapter on the Ordovician, I have already referred to two small 

 faunas described by Kayser from Kiau-tschang-pa ; these are derived from 

 horizon 1. The upper part of 1, however, being characterised by the follow- 

 ing fossils 



Ortlioccras sp. 



Spirifer clevatiis Dalm.

RJiyncliondla horcalis ScHL. var. sinoisis Kayser.

was believed to represent the Gotlandian age.^' G. Lindstrom^^ who studied 

 the Palaeozoic corals in Richthofen's collection, found in this horizon two 



new species, 



Ccri aster calaimtcs Lindst. Auiplcxiis viduus Lindst. 



The younger i and h also contain many brachiopods and corals of the 

 Middle Gotlandian age, the former being rich in brachiopods and the latter in 

 corals ; the fossils found in these two beds are, according to Kayser and 



LiNDSTROM :
