Loczv and Frech and were identified as follows : — 



Loc. Paj-sui-kiang^' in southern Kan-su. Along the gorge is exposed a 

 limonitic sandstone in association with cla>' shale; above the sandstone occur 

 thin-bedded limestone layers, and above these thick beds of the bituminous 

 I'mestone. Marly strata in alternation with the dark blue limestone layers 

 contain numerous fossil corals, crinoids, brachiopods, bivalves etc. among 

 which the following forms have been distinguished.

This small fauna was assigned by Loczv to Middle Devonian.-^ 



Loc. Hoa-ling-pu, in western Sze-chuan. In western and south western 

 Sze-chuan and in the adjacent districts of Yun-nan, Devonian rocks seem to 

 have an extended distribution ; according to Loczv, in the first region, 

 there are developed some Palaeozoic rocks, which overlj' granitic and diabasic 

 rocks on one side and underly a Rhaetic and Jurassic coal bearing formation 

 on the other ; the lower part of the Palaeozoic complex, composed mostly of 

 limestone, has no fossil, and assigned by him to Silurian simply on account of 

 the Middle Devonian age of the overl3ang part. The latter, composed of 

 shale and earthy limestone, contains a rich fauna of the said age at Hoa-ling- 

 pu^' ; according to P'rech'^' it is equivalent to the middle poraon of the 

 StrijigoctplLalns limestone. The fossils are :
