APPENDIX TO STFLZO CAVi: A: THE CAMEKAPORID^. 
The family Cameraporidae of Meimier & Pergens, 1885, includes 
a series of specimens that are probably closely allied to Stellocavea. 
The specimens all came from the Maastrichtian of Limburg. The 
‘ family ’ is not represented in the Museum Collection, and is of 
very doubtful value. 
The following summary of the classification according to Meunier 
and Pergens shows the chief characters and variations of these 
Bryozoa. The members of the family have a circular zoarium, 
in which the zooecia open in groups around the upper border of 
the disc; the groups are bounded by well-developed laminae (as 
in Stellocavea).

Char. — Zoarium 5 to 7 mm. in diameter, with ten to twelve radial groups of

epizoarial layer.

CLAIJSACAMERAPORA, Meunier & Pergens, 1885. 
Char. — The zooecial groups are broken into dumbbell-shaped areas, owing to 
the ingrowth of the sides, which may unite and convert a zooecial group into 
two detached groups of apertures. 
Type Species. — C. mamillata, Meunier & Pergens, 1885. Senonian — Maas-
