AKT. S. — H. YABE. 



found near Chho-san and Ui-uön, northern Phyöng-ang-Do, and 

 of plant impressions in a slate exposed near Mun-gyöng, northern 

 Kyöng-syang-Do. 



He also mentions indeterminable plant remains as occurring 

 in the slates of Naktong, Northern Kyöng-syang-Do, which are 

 said to lie unconformably upon gneiss, and to gradually pass 

 above to a thick complex of sandstones and shales. This forma- 

 tion was provisionally taken by him as synchronous with the 

 plant-bearing slate of Mun-gyöng, above alluded to, which he 

 believed to be of the Carboniferous age from the presence of a 

 species of Neuropteris which he compared to N. flexuosa Sternb. 

 But Professor Koto who has recently made extensive travels in 

 Korea considers these two plant-bearing rocks as belonging to two 

 distinct geological horizons, for the younger of which he proposes 

 the name " Kyöng-syang Formation." 



The second tour in the southern part of the peninsula was made in September and 

 October of 1904, for the purpose of tracing the extension of the Mesozoic deposists in tlie 

 southwestern portion of Chyol -la-Do including Na-jyu and Nam-uön, and in a narrow belt 

 of laud stretching northeastward from the said district to the southeastern corner of Chhung- 

 chliyöng-Do, where he had previously no opportunity of observation. Consequently, this 

 time, he traversed the Chyol-la-Do by the way of Mokpho, Yong-am, Nam-phyöng, Koang- 

 jyu, Tong-pok, Ok-koa, Nam-uön, Im-sil, Chyön-jyu, Chin-an, Yong-dam, Keum-san and 

 Mu-jyu, and then entering the Chhung-chhyöng-Do went as far as the Keifu-railway line, 

 then in the process of construction, at Yong-dong. Thence he made a visit to Ok-chhyön 

 on tlie west and to Hoang-gau on tlie east, and then went to Syang-jyu, Ham-chhyang, 

 Po-eun and Chliyöiig-san, returning to Hoang-gan after a week. In this way, the Syong-ni- 

 san ridge was crossed between Ham-chhyang and Po-eum from east to west. Afterward he 

 went along the railway southeastward by Chhyu-phung-nyöng, Keum-chhyön and Pu-sang, 

 to Tol-pa. Next a few days were spent in making a research along both sides of the Nak- 

 tong-gang between Tol-jja on the south and Nak-tong village on the north, and tlien going 

 from Tol-pa to Fusan by railway, the journey came to the end. 



Pakeontologlcally, no important results were obtained from this second journey of about 

 50 days. Only in the Mesozoic deposits of Yong-dong and its vicinity, a few plant remains 

 of an almost indeterminable preservation and consequently of very little or no value, were 

 obtained in a slaty rock harder, though geologically a little younger, than the shales of 

 the Nak-tong plant beds. From tlie latter, on the contrary, he got 4 or 5 additional species, 

 not found in the collection of the preceding year.
