containing a few plant remains, mostly indeterminable. Below 

 these four parts, there is a thick conglomerate gradually passing 

 below into a sandstone Avitli intercalations of shales which are 

 sometimes coaly. 



As to the distribution of these parts in Kyöng-syang-Do, 

 the uppermost shows a wide extent around Fusan, while the 

 lowest appears along the boundary of the Mesozoic area against 

 granite and gnesis in the west ; the other two parts occur in 

 areas between these two, although their distribution has in many 

 cases become complicated by dislocations. 



The upper conglomerate, No. o of Gottsche, is distinguished 

 from the lower usually by the occurrence of a red tuff' and 

 amygdaloidal rock sheet below it and also by being covered by 

 a thick series of a red tuff* above. A similar rock series also 

 forms an extensive area in southern Chyol-la-Do and in the 

 narrow belt between Chang-syöng and Yong-dong. In the latter, 

 it is underlaid by thick greenish and black slates. Gottsche 

 differs from the writer in considering this conglomerate exposed 

 near Chin-an as the equivalent of a similar rock which he calls 

 No. 3 in his Nak-tong section, and consequently in taking the 

 underlying complex as corresponding to No. 2 and No. 1. But 

 the writer, from his own observation, is inclined to consider the 

 conglomerate as representing the upper horizon, i. e. No. 5 of 

 Gottsche, while the lower series probably corresponds to his 

 No. 4. 



According to the writer's opinion, the lowest part of the 

 Kyöng-syang formation is to be distinguished from the rest, 

 under the name of the Naktong series. It seems exactly to 

 correspond to the divisions. No. 1, No. 2, and No. 3, of 

 Gottsche. It is characterized by loose sandstones and inter-
