The discovery in Yorkshire of twelve of the last thirteen 
species is due to the excellent field investigations in quest of 
Mycetozoa, or Myxomycetes, carried on by Mr. T. Petch, 
B.A., B.Sc., during 1903-4. A few were new to Britain. 
Altogether Mr. Petch found in the East Riding upwards of 
sixty species of this group, Vzde. Trans. of the Hull S. and 
F. N. Club, ’05, pp. 196-208. Here we have another example of 
what may be accomplished in field research by persistent work 
as opportunity affords. 
In a paper upon ‘Local Birds,’ by Mr. C. F. Innocent, read recently 
before the Sheffield Naturalists’ Club, the following classification was 
suggested as more detailed than the usual meagre division into residents 
and migrants. 
(A) Residents :— 
1. Eu-residents: resident all the year through, e.g. house sparrow. 
2. Pen-residents: resident all the year through, except for a few 
weeks, e.g. starling. 
(B) Migrants :-— 
3. Pseudo-residents : resident as species, but migratory as indi- 
viduals, e.g., robin. 
4. Winter residents: e.g. fieldfare. 
5. Summer residents: e.g. swallow. 
6. Eu-migrants: which only visit on autumn or spring passage to 
winter or summer residence, e.g. ringed plover. 
(C) Erratics -— 
7. True waifs and strays: e.g. puffin. 
8. Archzeo-residents: which formerly lived in the district and of 
which individuals occasionally return to former haunts of the 
species, e.g. eagle.
