probably belong to another genus. Slachela has a range from 

 Silurian to Lias.^^ 



Ill conclusion, I desire to express my obligations to the 



gentlemen who have had the kindness to allow me to use 



materials collected by them. To Prof. M. Yokoyama, I also 



tender my best thanks for his courtesy in looking over this 

 paper while in manuscript. 



1) Chapman counted six species of the genus in the Khaetic rock of Somerset; some 

 of them are indeed specifically identical with those of Carboniferous (Chapman: Rhaetic 

 Foraminifera from Somereset. Ann. Mag- Xat. Hist. XVI. 1895). Also a Devonian species 

 found hy Schubert in a liujcstone of Bohemia is very like S- pohjtremaloides Brady from 

 Carboniferous. (R. J. Schubert u. Ad. Liebus: Vorläufige Mittheiluug ii. Foraminiferen 

 aus dem Böhmischen Devon. Verli. d. k. k. geol. Reichsanstalt 1902. p. ü(3). Therefore, 

 the Foraminifera though interesting in itself, has no vahie for geological correlation. 



Postscript. 



Very recently, Prof. Yokoyama found Fudozamites lanceolatns and 

 (Hadopldcbis Wldthyeims in a collection of plant-remains from Kam-peuk- 

 uön near Phyong-yang. This comfirras Mr. Iki's view, mentioned above ; 

 but without further knowledge on the geological relation extisting between 

 tlie plant bed and the coal bearing formation, the problem on the geo- 

 logical age of the latter above alluded to, is left unsettled for ever. 



The remarkable occurrence of a peculiar, elongate species of Fitsidlna 

 ill a calcareous sandstone of Tsukitate, near Kesennuma, prov. Rikuzen, 

 was accidentally omitted in the note on Japanese Fusid ina (p. 11).
