Trachelizus hisulcatus, Lund, Mons. Power informs me, is 

 common in the extreme East, and that specimens have been 

 reported from China and Japan. In the Munich Catalogue the 

 locality given is Java ; and I hesitate at present to include it in 

 the Japan list.

I. Introduction. — The former communication on the structure 

 of the sclerenchyma of the Fungidse related to the subfamily Fun- 

 giiise ; the present concerns the structural details of some of the 

 compound corals belonging to several of the recent genera of the 

 subfamily Lophoserinse. 



An examination of the recent LophoserinsB is absolutely requi- 

 site before the classificatory position of many extinct genera of 

 corals can be decided. Hence the examples chosen to illustrate 

 this communication have a palseontological bearing ; but I do 

 not enter into the subject of the construction of the forms included 

 in such genera as Comoseris, Oroseris, Thamnastrcea, &c., because 

 it belongs more to the province of the Greological Society ; and 

 this essay is introductory to such a one. 



; Very soon after this communication was commenced, I became 

 aware that the internal structures of the compound Lophoserinse
