I now believe that in the specimen (or specimens) on which 

 Monoporella albicans was founded the sinus was not absent, 

 but was entirely concealed by the suboral umbo, as it is, I 

 find on reexamination, in many of the cells of the other form. 

 Monoporella albicans therefore must merge in Schizoporella 

 aperta.

The larger cells with modified orifice are now known to 

 occur on many species and are no doubt subservient to repro- 

 duction. MacGillivray rightly refers Carbasea [Flustra) 

 episcopalis to this genus ; but he does not mention whether 

 it possesses the two classes of cell.

Stirpaeia, Goldstein. 



It may be a question, I think, whether this genus can be 

 maintained. The erect segmented stem seems to be the one 

 peculiarity which separates it from Bicellaria *, with which 

 it entirely agrees so far as the zooecial characters are con- 

 cerned ; and the morphology of this structural element has 

 hardly been determined as yet with certainty. There is a 

 close resemblance between the stem of Stirparia and that of 

 the genus Kinetoskias of Koren and Danielssen, also a 

 Bicellarian form.

In a paper on " Tertiary Chilostomatous Bryozoa from New 

 Zealand " f Mr. Waters has identified his Membranipora 

 articulata % with the present species, and expresses an opinion 

 that if I had " decalcified " my specimens I should have taken 

 the same view. Circumstances have prevented me from
