VERRUCOCGLIA MAJOR. 201 
This specimen was made, by Prof. Sollas, the type of a distinct genus, but in 
its mode of growth and in the character of the canals and spicular structure it 
sufficiently resembles some of the forms included by Prof. Zittel under Verrwco- 
celia to be included in this genus. The form appears to be very rare. 
Distribution.—Inferior Oolite. Parkinsoni-zone in the Cliff-section at Burton 
Bradstock, Dorset. (Coll. Rev. G. F. Whidborne.)

The typical species, based on a single fragmentary specimen, consists of a 
small group, 50 mm. wide by 30 mm. in height, of short branching tubes, 
frequently intergrowing laterally with each other; the basal portion of these 
tubes is not preserved, so it cannot be told whether they originate from a 
common hollow base or not. The tubes are usually compressed, from 5 mm. to 
8 mm. in diameter ; their walls are from 2 mm. to 3 mm. in thickness, and shghtly 
thickened at the summits. The ostia of the outer surface are closely but irregularly 
disposed, and about °5 mm. in width; those of the inner surface appear to be 
arranged in longitudinal grooves. The skeletal mesh is regular, and the nodes 
are about "16 mm. apart. — 
This specimen has also been made the type of a new genus, but it does not 
seem to be generically distinct from Verrucocelia.

The only known example of this species is contained in a small compact nodule of 
limestone, the upper surface of which shows the apertures of several tubes, with 
flattened, somewhat thickened margins. The tubes are from 8 mm. to 11 mm. in 
diameter, their walls 3°5 mm. in thickness, and the inner cavity 3°5 mm. in width.
