* In preparing a list o£ Bryozoa from Oran (Algiers) a few specimens of 

 Cupularia Johnsoni, Busk, have led me to more extended studies for a better 

 understanding of the whole of the group ; however, a large number of spirit 

 or fresh specimens are required for a complete study of this little understood 

 group, which is one of the most interesting. This communication makes no 

 pretension to dealing exhaustively with it, being principally remarks on some 

 species in my collection. 



I had previously received, from the late Canon Norman, a few spirit 

 specimens of three species of Cupularia, collected off Madeira, namely, 

 C. canariensis, Busk, C. Johnsoni, Busk, C. Lowei, Busk, each of which 

 revealed new structures, in stained preparations and sections. 



Of what have been considered as Selenariadse all are more or less cup- 

 shaped or flat, and though now the shape aloue would not be considered
