Tipula lateralis was handed to me, but no others were noted. The winter 
midge, Trichocera regelationis was about and a cloud of small midges, 
Spaniotoma ( Limnophyes ) minima Mg. danced in a sheltered corner at 
the stream head. Under a stone amongst a nest of Ants I got a single 
Bibio laniger Mg. 
A little sunshine brought out a good many flies on the sea shore 
about heaps of old Laminarias'. Fucellia fucorum Fall, was plentiful, 
with an odd female F. maritima. Coelopa ( Fucomyia ) frigida Fin. in a 
great variety of size, and a lot of the small Limosina zoster ce Hal. I am 
indebted to Dr. F. W. Edwards for the name of the midge and the Bibio, 
the latter being abnormal, having the thoracic hairs dark and a thinner 
hind metatarsus than usual. 
Conchology (Mrs. E. M. Morehouse) : — During the Easter Meeting 
rather more attention was devoted to the marine molluscs than the 
land, the names may appear unfamiliar for our marine species, but the 
Concho logical Society of Great Britain and Ireland have approved of a 
new list compiled by Mr. R. Winckworth, M.A., which is a monument 
of patience on the part of the author and has meant many hours of hard 
work. The most interesting ‘ finds ’ included two slugs, three molluscs 
of the Patellidce and Turtonia minuta, a very small bivalve taken on the 
underside of stones at low water mark, while L. saxatilis was found in 
quite a new surrounding for them, on stones under Fuscus versiculosus 
and F. platycarpus , this species one looks for on boulders, etc., at high 
water level. Mr. R. Winckworth very kindly verified the two latter 
species. Patina pellucida seemed rather rare, there ought to have 
been plenty on the Laminarian weed, further south to Scarborough it is 
fairly common.
