Rev. S. Graham Brade-Birks on MLlyriapoda., 211 
amazed at the number of Woodlice, Myriapods, Mollusks, and 
other small nocturnal animals which the exceptional meteoro- 
logical conditions had brought out at mid-day. ‘The stones 
on the ‘screes,’? the wet faces of the rocks, and tree-trunks, 
absolutely swarmed with them. I sat down before a sloping 
rock about two yards square and tried to count the Woodlice, 
- ete., but had to give up the task. The rock-face was almost 
covered with tiny Lichens, Moss, and Liverwort, amongst 
which I counted fourteen fine examples of the beautiful 
Schizophyllum sabulosum slowly meandering, reminding me 
stronely of young Blindworms (Anguds fragilis) in their 
coloration and movements. Watching these very closely 
through a lens I found that they were feeding on the Liver- 
wort.... In the same space I also noted five Glomeris 
marginata ; seven Tachypodoiulus niger... .” 
Economic STANDPOINT AND FUTURE INVESTIGATION. 
It was evidently realized long ago that a knowledge of the 
wandering of millipedes might be of some importance to the 
economic zoologist, for Miss Ormerod (1895), p. 81, says “it 
seems to me we need special investigation as to the possi- 
bilities of migration.” 
Facts which have come to the writer’s notice, and just 
recorded above, throw some light upon the subject, and he 
hopes that further progress towards a solution of the problems 
involved may be made by the co-operation of other workers 
during 1922. The pursuit of other researches have, so far, 
made it impossible to devote the time it would require to a 
full investigation of the matter. 
It would be advantageous to have observations nightly— 
say, one hour after sunset-—on measured stretches of road, 
and to have records made of the numbers of millipedes 
collected, their species, sex, and ontogenetic stage; thus each 
specimen should be preserved for examination and identifica- 
tion, and the number of pairs of legs should be counted and 
each animal measured. Weather conditions should also be 
taken into account. 
It would also be a good thing if it could be definitely deter- 
mined whether individuals travel any great distance. 
THE OCCURRENCE OF Szosarea rrazica (LATZEL). 
I had taken this animal sparingly in the Vicarage garden 
at Wye in 1920. In 1921 Mr. Bagnall found it in consider- 
able numbers among decaying vegetable matter on the *
