Sponges compound, branching; the branches in some instances radiating 
from a central tube or cavity, in others they spring from a common base and 
inosculate with each other. The ostia of the walls are numerous, small, and 
without regular arrangement; canals nearly straight, those from opposite sides 
of the wall alternating with each other. The skeletal mesh regular, with compact 
nodes, as in Craticularia. The type species is Verrucocelia (Scyphia) verrucosa, 
Goldfuss (* Petref. Germ.,’ vol. i, p. 91, pl. xxxiui, figs. 8 a—e), from the middle 
beds of the White Jura, near Streitberg.

The type and hitherto the only known example of this species has a fan-shaped 
outline, measuring 110 mm. in width by 90 mm. in height; the basal portion is 
incomplete, but from it several main tubular branches are given off which 
subdivide and terminate in truncate, conical, teat-like tubes projecting either 
directly or obliquely upwards, whilst the direction of the main branches is nearly 
horizontal. These projecting tubes range up to 8 mm. in diameter; some are 
nearly sessile, whilst others extend about 16 mm. above the level of the basal 
branches, their summit apertures are from 2°5 mm.to 4 mm.in width. The ostia 
of the outer surface are about ‘5 mm. in width. The spicular mesh is regular, 
and the distance between the nodes about 15 mm.
