794 ON POLYZOA (BRYOZOA) FOUND IN THE BORING AT RICHMOND.

This species is an incrusting one, and as such it has no special 
form otherwise than that given to it by the shape of branches &c. 
upon which it grows.

One fragment only, which I place doubtfully in this genus, and 
as but one form of it is known in the Great Oolite, as a repre- 
sentative of this species. It may, however, belong to the genus 
which Haime retains as Apseudesia, Lamx.

It is useless to give the variety of synonyms of this species as 
given by Prof. Brauns. It will be necessary to have sections of the 
forms before any details of structure are supplied. The student of 
this peculiar species will find ample references to typical structures 
on reference to Prof. Nicholson’s paleontological works: but no 
definite conclusion respecting its classificatory position has as yet 
been arrived at.
