fined myself to a search for fucoids chiefly which are much 
admired owing to their excellent preservation there. On one 
of my visits, however, I got the head of a Lyriocrinus ; the 
plates are rather crushed and it looked a little better when 
partly concealed in the soft shale. The slabs at Grimsby 
require weathering in order to show the numerous 4ryozoons 
on the surface. All the best ones have been already removed 
by the writer, Nicholson and Hinde several years ago. 
CLINTON AND MEDINA. 
If any intention ever existed of re-opening the Medina 
quarries east of the Jolly Cut, it must have been abandoned, 
or I may have been misinformed, and the difficulty now of 
obtaining Clinton specimens in the old workings has been 
increased greatly of late owing to landslides of surface soil 
from above, which were caused by the heavy rainfall in an 
early part of the collecting season. ‘This is more to be regret- 
ted since organic remains of the series are very poorly repre- 
sented in our museum cases, and the Clinton slabs especially 
were highly prized by Paleeontologists. Three crinoids found 
in these beds are tinrepresented. Fortunately before the. 
Eastern Incline destroyed the only place where, as far as I 
know, colored cranias were obtainable, I placed one of the few 
found there in the upper case. The only one in my own 
possession was sent not long since to the National Museum, 
Dublin, claiming that ‘‘it retained the original coloring 
matter’’ as it was found to exist in the living Avachiopod 
dredged off the coast of Norway. The members of the section 
may remember the specimen which was attached to a Flustra 
and was submitted to your inspection at our opening meeting 
last year. ‘The wing shell Avzcu/a here displayed comes from 
the Clinton Iron band which I believe in this locality at least 
represented a mud flat very slightly elevated above the sea at 
low water and which was partly submerged occasionally so as 
to permit burrowing shells to enter, and it may be that the 
single valves of the Limgulid@ found in the band in such 
extraordinary numbers can be best explained by supposing as
