to be found. One very interesting species turned up, however, 
in Nemoura inconspicua which occurred commonly on a 
narrow beck which runs down to the sea shore on the cliffs 
south of Filey, and is a new record for the count}''. Silo pallipes 
occurred in the same spot ; as did also the fine Hymenopterous 
sawfly, Trichiosoma lucorum about hawthorn. On the small 
pond on the cliffs beyond there, Ischnura elegans and Grammo- 
taulius atomarius were taken, and Nemoura variegata was 
common. 
Marine Biology. — The Rev. F. H. Woods writes : — The 
tides were not suitable for shore work, but Dr. Irving, who on 
Saturday made a careful examination of rocks and pools at 
the neck of the Spittal gives the following account of its results. 
I found many species, reported last September, which need 
not be enumerated. Doto coronata. several good specimens 
occurred among the Sertularia attached to Chondrus. I found 
one bright specimen of the rare anemone Sagartia venusta. 
A somewhat unusual variety of Sagartia troglodytes I detached, 
from a limestone rock. A small specimen of an solid Cory- 
phella rufibranc/tialis (gracilis) may likewise be added to the 
list.’ 
My own share of the work was practically confined to the 
microscopic study of drift. Altogether I discovered 73 species 
of shell molluscs, of which 70 occurred, though not exclusively, 
in the drift. It is interesting to note that, though none of them 
are new to Filey, they include five out of the six additions ta 
the Marine Fauna of Filey mentioned in The Naturalist for 
April, p. 130, the exception being Nuculana pygmaea. But 
some of them are worn or fragmentary. Among other rare 
shells may be noted Astarte compressa and a minute specimen 
of Ondina obliqua. The latter is seldom to be found except in 
a very young condition on the Yorkshire coast. I also noticed 
a very young specimen of Sepiola scaudica among the debris 
from the shrimp nets. This should also be added to the Filey 
list. 
At the evening meeting on Saturday a very useful suggestion 
was made that those living at or near the coast should occasion- 
ally send parcels of shell sand or fine drift to those working at 
a distance. Mr. Foster Smith, the Headmaster of the Church 
School at Filey, has kindly consented to act as purveyor, and 
the secretaries of local societies, who wish to take up the work, 
would do well to communicate with him. It should be realised, 
however, that some care should be exercised in choosing the 
material, which should be neither too fine nor too coarse. If 
it contains any shells, it probably contains many and of many 
kinds. I seldom find less than 60 species in say a quart of 
drift.
