long, curved zooidal tubes x 10.5. 24, detail of longitudinal section, x 33. 25, overgrown gonozooids visible in the transverse section, x 33. 
DESCRIPTION. Colony encrusting, more-or-less circular, maxi- 
mum diameter 4.43 mm, maximum height 0.84 mm, completely 
adnate or the margin, slightly elevated above the substratum; mar- 
ginal basal lamina little apparent, 0.35 mm wide where present; 
behind marginal lamina is a 0.75-1.31 mm wide zone of 
autozooids and kenozooids. Autozooids without projecting 
peristomes, and not aligned in definite radii, although up to 3-4 
non-connate apertures may occur in a radial row amongst 
kenozooids; apertures 0.11 mm in diameter, the rim of even height 
all round. Kenozooid apertures 45-70% of the diameter of 
autozooidal peristomes, none closed by diaphragms. Brood cham- 
ber occupies most of colony centre, broken in the present colony; 
floor marked by thin layer of calcification over autozooids and 
kenozooids; almost none of the brood chamber roof remains ex- 
cept for a tiny area which indicates that thick-walled zooidal 
chambers may occur above the roof.
