Introduction. 



Palseontologically speaking, Korea'^ is the least known of all 

 the countries of Eastern Asia. The first notice on Korean fossils 

 is found in Gottsche's " Geologische Skizze von Korea ", in which 

 he mentions the occurrence of a Cambrian fauna in a limestone 



1) Having arrived at Chemulpo (Inchliyön), Korea, in the end of August, 190.'], the 

 present writer was engaged in field work for about two months up to the beginning of 

 November, when he took his way home from Fusan (Pusan). During the month of Sep- 

 tember, he made a journey along one of the main roads from Seoul to Fusan, through 

 Tyo-ryöng on the boundary of northern Kyöng-syang-Do and Ciihung-chhyöng-Do, in order 

 to obtain a general knowledge of the various geological formations in which there was 

 probability of the occurrence of organic remains, and especially to make a collection of the 

 Palaeozoic plant fossils at a locality close to Mun-gyöng, known since Gottsche's explora- 

 tion. From the 3rd to the 15th of October, he made a second tour from Fusan to Yöng-il 

 along the eastern coast, making there a collection of plant fossils in the younger deposit 

 of the said district. The existence of a plant deposit of a very recent age in this district 

 was one of the important discoveries of Prof. Koto. During the remaining days, the writer 

 was able to traverse Chyol-la-Do, starting from Mok-pho, by the way of Chyang-syöng, 

 Chin-an ; thence he crossed Yuk-sim-nyöng, and traversed Kyöng-syang-Do for the third 

 time, passing near An-eui and through Chin-jyu, Sa-chhyön, Chin-hai and Masampho. 



The paleeontological collections made during his first two months stay in the peninsula 

 comprise : — 



I) Plant fossils of the Palaeozoic (?) from a locality near Mun-gyöng. 



II) Plant fossils of a middle or upper Mesozoic age from Naktong. 



III) Plant fossils of a younger Tertiary age (?) from Yöng-il.
