222 LISTER : THE STUDY OF MYCETOZOA IN BRITAIN. 
and Devon, and (4) from Aberdeenshire, Elginshire, and 
Nairnshire. The specimens from the first three counties 
were collected for the most part by Mr. James Saunders, 
A.L.S., of Luton, who has been for twenty-four years 
an enthusiastic and earnest student of Mycetozoa. His 
observations, carried on year after year in a great variety of 
situations — in upland woods, on sand or chalk, in swampy 
thickets, or among straw heaps lying undisturbed on open chalk 
land — have added much to our knowledge of British Mycetozoa, 
their habitats, and their distribution generally. Mr. Saunders 
has also done much good service in making the study of My* 
cetozoa popular and by attracting other observers to this field 
of work. He has published lists of species found in the counties 
of Beds, Herts, Bucks, Middlesex, and Essex, in the Transactions 
of the Hertfordshire Natural History Society for 1911. 
For the last nine years, Bedfordshire has had another success¬ 
ful and diligent collector of Mycetozoa in Miss Katharine Higgins, 
who has added new species to the county records. Amongst 
them, one, Arcyria insignis, is new to Britain. I am greatly 
indebted to Miss Higgins for having supplied me for the last 
eight years with monthly reports of the species she has found. 
The specimens from North Somerset were collected by 
Miss Agnes Fry. 10 Those from the south of that county were 
found by Mr. Norman Hadden, who has also hunted most 
successfully in North Devon. A list of North Devon Mycetozoa, 
with full notes, was published by him in the Journal of Botany , 
1916. The gatherings from. South Devon were made by my 
father and myself. 
Our knowledge of the Mycetozoa of Aberdeenshire is due almost 
entirely to the Rev. William Cran, of Skene, whose industry 
and magnificent powers of vision have made known to us several 
new species, and have brought to light a number not previously 
found in Britain. To the Aberdeenshire list, I add the species 
obtained during the ten-days’ meeting 01 the British Mycological 
Society at Forres, in the counties of Elgin and Naim, in 1912. 
It is with a warm feeling of gratitude that I thank my fellow- 
workers and friends for allowing me to make use of their obser¬ 
vations, and for all the invaluable help they have afforded me. 
10 A list of these was published in the Proceedings of the Bristol Naturalists’ Society, fourth 
series, vol. iv., pt. i (1914).
