4, “Silurian Uniserial Stomatopore and Ascodictya.” By G. R. 
Vine, Esq. Communicated by Prof. P. Martin Duncan, F.R.S., 
F.G.S. 
For the genus Stomatopora the name Alecto has priority; but as 
that had previously been applied to a member of the class Echino- 
dermata, the author preferred the later name. Species of the genus 
have also been described under the generic name Aulopora. The 
author has received from Mr. Maw more than two hundredweight of 
washed débris of Wenlock shale, about thirty pounds of which, from 
twelve localities, he has examined. It contains a moderate amount 
of Polyzoan remains, generally water-worn. The author described 
the following species—Stomatopora inflata and dissimilis, -Asco- 
dictyon stellatwm and radians (with a variety siluwriense), and dis- 
cussed the characters of the genera. 
5. “On a new Comatula from the Kelloway Rock.” By P. H. 
Carpenter, Esq., M.A., Assistant Master at Eton College. Commu- 
nicated by the President. 
The specimen, to which the author’s attention was called by R. 
Etheridge, jun., Esq., is in the national collection; he proposes 
for it the name Actinometra calloviensis. The specimen’is from the 
Kelloway rock, of Sutton Benger; the whole diameter is 15 mm.; 
diameter of centrodorsal 6mm. Three species of this genus are 
already known from the British Jurassic rocks: two are only known 
from their ceutrodorsals, which are each different from that of 
A. calloviensis; the third is A. cheltonensis, from the Inferior Oolite,
