II. DESCRIPTION OF THE FOSSILS. 

 A. Bryozoa. 



Cellepora formosensis, sp. no v. 



(Plate II, figs. 2, 4, .3 and G ; Plate III, fig. 1 ; Plate IV.) 



In some rough " Notes on Microscopic Sections of Lime- 

 stones " from Formosa which we furnished to Dr. Kotö of Japan 

 in 1900 and which (although we had not prepared them for 

 publication) Dr. Kotö kindly published in the Journ. Geol. Soc. 

 Tokyo, June 1900, Vol. VII, we referred several times to the 

 occurence of a large " chambered organism." The material which 

 Dr. Koto has now sent to us includes the Formosa fossil which 

 is shown of the natural size in Plate II, figs. 4, 5, and 6. 

 This fossil is very dense and highly crystalline ; it is entirely 

 free from matrix and had been cut in two directions before it 

 reached our hands. On polished surfaces and in thin sections it 

 still furnishes details of its microscopic structure. Figure 6 of 

 Plate II gives the vertical view of the specimen, but the cutting 

 process has robbed it of some of its height ; fig. 4 gives the 

 basal view and there the loss sustained by cutting is shown by 

 plaster filling ; fig. 5 gives the actual view of the basal section 

 of the upper segment shewn in fig. G ; Plate IV is a reproduc- 

 tion of an enlarged photograph of the central portion of fig. 5; 

 fig. 2 of Plate II presents a microscopic section of the fossil 

 viewed by transmitted light : and fiff. 1 of Plate III "Ives
