566 REPORT—1885. ¢ 
Originally Mr. Hincks founded the genus Monoporella for species of 
the Microporellidian orifice, but destitute of the median pore, which is so: 
striking a character of the genus Microporella. Subsequently the author 
arranged the few known recent forms under the family name given 
above. Mr. Waters adopted the name—provisionally—for the fossil 
species which are given in the fifth Report on Fossil Polyzoa (mhz). 
As yet we have hardly material enough for a full study of the type. 
The genus is not given by Mr. Busk in his ‘ Challenger Report.’

In the Escharide Mr. Busk includes no fewer than fourteen 
genera, and as the family partly supersedes the Myriozoide of Smitt and 
Hincks, the following genera are left out in the classification of Mr. Busk 
in the ‘Challenger Report.’ They will be reported upon when I have 
concluded the family arrangement as given in the ‘ Challenger ’ mono- 
graph.
