Polyzoarium pedunculate, caj)itate; capituluin simple or divided into lobes ; the conti- 

 ;uous tubes opening irregularly on the upper surface.

1. F. QUADRICEPS, («. sp.) PI. XVJI, fig, 3. 



Capitiilo quadrifido ; lohis singulis medio excavatis seu depressis. Cellularum oriticiis 

 in cristis irregularibus e centro radiantibus pleruraque positis, subinde autem totani 

 superficiem occupantibus ; stipe porosa, infra attenuata. 



Capitulum quadrifid ; each lobe depressed in the centre ; openings of cells disposed 

 to run in crests radiating from the centre, or uniformly over the surface, stem porous, 

 attenuated downwards.

This species bears so close a resemblance to Func/ella prolifera. Hag. (' Maast. 

 Kreideb.' p. 37, pi. iii, fig. 6), that it is difficult at first sight to perceive that there is 

 much if any difference between them. The following distinctions, however, will be 

 found to exist. In F. prolifera the stem is described as smooth, longitudinally 

 striated and ringed transversely, whilst in F. quadriceps the surface of the stem is 

 entirely covered with distinct elongated pores. The fourfold division of the capitulum 

 appears to be a constant character in F. quadriceps, but which, though shown in the figure, 

 is not specially adverted to in the text. Neither does Dr. Hagenow notice the depressed 

 centre of each lobe and the radiating disposition of the openings of the cells, often so 

 manifest in F. quadriceps, and showing the close relationship of the genus to Defrancia. 



2. F. MULTIFIDA? {71. Sp.) PI. XVIl, fig. 4. 



Stipe brevissimo, ad basim incrassato. Capitulo in lobis bifidis numerosis subcompressis 

 vel rotundis diviso. Cellularum orificiis sequalibus per totam superficiem dispositis. 

 Stipis superficie glabra, lineis delicatulis areas hexagonas circumscribentibus ornata. 



Peduncle very short and thick, expanded at the base ; capitulum divided into nrune- 

 rous bifid subcompressed or cn-cular lobes, which are convex on the surface ; openings of 

 the cells of uniform size and disposition ; surface of base and peduncle smooth, divided 

 into hexagonal areas by reticulating lines.
