NO. 1401. GENERA OF SIMPLE FUNGID CORALS— VAVGHAN. 417 



2. Genus PSAMMOSERIS Miltie Edwards and HaiiTie. 



1851. /'xaiiiiiioxi'ri.'< Milne Edwards and Hai.me, Arch. Mus. Hist. Nat. Paris, 

 V, p. 127. 



Placed ill the I.ojjhoserinse. 



Or'tginal generic diagmms. — "Coralliim discoid, attached to a shell 

 which it completely surrounds; wall naked, strongly granulate, scarcely 

 striate below; columella papillaiT; septa slightly elevated, very thick, 

 covered on their free edges and their faces with very prominent and 

 extremeh^ crowded granulations, those of the penultimate cycle much 

 more developed than those of the last."' 



Type-species. — HeterocyatJius hemisphivrlcus J. E. Gray, Proc. Zool. 

 Soc. London, for 1849, p. 77, Radlata., pi. ii, tigs. 8, 8a, 4; also Ann. 

 and Mag. Nat. Hist., 2d .ser., V, 1850, p. 410. 



Distrihution. — Recent, China seas. 



Remarks. — The systematic position of this genus is in doubt. 

 Moseley was evidently of the opinion that JL'terop><ainiida and Fsanio- 

 .ser/'s .should be united," although, prol)ably l)y a lapsus calami^ he says 

 IlettropmiiHiiiuc and Sffj>haiioser!i<. Von Marenzeller has expressed 

 the same opinion.'^ 



Family STYLOPHYLLID.E Volz.^

Volz gives'' a careful description of the septa, endotheca, wall, and 

 mode of growth. His description will not be repeated here. 



The following two genera, Stylojthylluin Reuss and Sfyfophyllopsis 

 Freeh, can scarcely be referred to the Funglda., l)ut, as they are veiy 

 interesting forms to study in connection with a possible phylogeny of 

 the Fungids and Eupsammids, they are included in this paper. 



1. Genus STYLOPH YLLUM Reuss. 



1854. Stylopliylluin, Reuss, Denksch. Akad. Wissensrh. Wien, I\lut. Naturhist. 

 CI., VII, p. LS2. 



Original generJe diagnosis. — "The form of the corallum unknown; 

 but its upper surface must have been plain or only slightly arched. 



"The thick prismatic, irregularh' polygonal corallites are directly 

 grown together. The thick walls are compact and entire, without a 

 trace of pores or perforations. In both the transverse and longitudi- 

 nal sections the line along which the walls of neighboring corallites 

 have fused can be seen.

 ''These corals are not considered to belong to the Fungida. They are included 

 because of the interest in comparing tlieni with the FuiKjUJd and the Eapaammklie.
