Syn. TInicrisia compressa, d’Orbigny, 1853. Bry- Cret. p. 600, pi. 734, 
figs. 12-14. 
Chak. — Known by three zooecia which are very compressed. Peristomes highly 
raised. Surface smooth ; sutures between the zooecia obliterated. 
Distrib. — Senonian : near La Ferte- Bernard, Sarthe. 
Aff. — T he generic position of the type fragment is doubtful. There is no trace 
of the articulation, and the peristomes are unusually highly developed.

Char. — Zoarium articulate ; each interuode includes one or two zooecia, and each 
segment is from 1’5 to 1*75 mm. long. Zooecia from •25 to ^3 mm. diameter, 
with apertures •IS to •2 mm. diameter. Walls smooth. 
Distrib. — Cenomanian ; Plauen, Saxony. 
Pamily THEO^^OID^, Busk, amended.^ 
Diagnosis. 
Cyclostomata Tubulata in which the zooecia are simple, short, 
open tubes. They often pass through a I>efrancia-^i?Lge. 
The zooecia are monomorphic. The apertures occur in bands 
either along raised ridges or along the edges of the fronds.
