DIAGNOsIS. A small Lichenopora, not more than 2.5 mm high, the 
cone angle 45—85°; kenozooidal props present or absent; tubercle- 
like thickenings of zooidal walls near the disc centre. 
DESCRIPTION. Colony conical (Figs 11, 13—15, 17), tiny, about as 
D.P. GORDON AND P.D. TAYLOR 
wide as high, preserved size not exceeding 2.5 mm high and 3.4 mm} 
in diameter, the angle of the cone 45—85°. Outer (basal) surface of " 
cone textured with faint concentric growth banding; cone apex! 
symmetrical, rounded, or slightly irregular according to the substra- 
tum. Short, hollow kenozooidal props (Fig. 15) occur on some) 
specimens, as many as 3 on one side, or these may be entirely absent. | 
Disc nearly circular in outline, surface significantly depressed below | 
the rim in well-preserved material (Fig. 14). Disc surface convex, 
rising to short prominences near the centre. 
Zooids arranged in irregular quincunx, with considerable varia- “hy 
tion in apertural diameter, size generally increasing centripetally:| 
the largest apertures (up to 0.20 mm in diameter) are assumed to be} _
