vine: polyzoa of the wenlock shales. 
species are very prolific, and the colonial growths cover alike stems of 
crinoids, shells, and many of the specimens of the Bryozoons of 
American authors. 
I have no record of Stomatopora in either the Devonian or car- 
boniferous rocks of this country, and so far as I am acquainted with 
the literature of the gi'oup, I have no notes or descriptions of species 
from similar horizons of other countries.

This species appears to me to be a true Stomatopora, but very 
little detail is afforded by the author, either in the diagnosis or 
figure. 
Habitat: Adherent to the outer exterior of Productus horridus. 
Localities and Form : Permian rocks, Humbleton quarry ("where 
it is rare." King.) 
Some of the multiform species of Professor Nicholson would, 
under ordinary grouping, be placed in the sub-genus Proboscina. 
]\Ir. E. 0. Ulrich places ,the name as a genus after Stomatopora and 
before his genus Berenicea, but proboscina is regarded by Hincks as 
belonging to the Stomatoporae, and in his diagnosis of the genus 
Stomatopora he provides for the multiserial forms. 
In one of my earlier papers"- I endeavoured to grapple with the 
Paheozoic genus Berenicea, species of which had been located either as 
Diastopora or Berenicea, and I suggested that the B. megastoma 
M'Coy should be placed rather as a Ceramopora as defined by Hall 
(I. c. pp. 358-9), at the same time accepting Ceramopora as a 
member of the Diastoporidae which I then sought to establish. 
Since then gi-eat advances have been made, and had I been
