FRESHWATER RHIZOPODA AND HELIOZOA OF SCOTLAND 231 



In addition to the above, two new species were obtained, viz. 

 Nebela scotica from Ben Ledi, a form apparently related to N, 

 dentistoma, and Euglypha bryopliila from moss gatherings i, 4, and 

 10, a "cristate " form quite distinct from E. cristata. These species 

 are fully described and figured in a paper read before the Linnean 

 Society on 4th May last. 1 



Gatherings of this type are not very suitable for the examination 

 of Heliozoa, but the following species occurred in the sphagnum 

 material : 



Actinophrys sol., Ehrenb., in i, 3, and 4. 

 Actinosphcerium Eichhorni (Ehrenb.), Stein, in i. 

 Raphidiophrys pallida, Schulze, in 7 and 12. 

 Acantlwcystis pertyana, Archer, in i, 7, 8, and 10. 

 Hedriocystis retieulata, Penard, in i. 



(The numbers refer to the columns in Table I.) 



From the foregoing tables the following general observations can 

 be made : 



i. The following genera and species appear to be restricted to 

 sphagnum. 



Genera : Hyalosphenia. 



Placocysta. 



Ditrema. 



Amphitrema. 

 Species : Sphenoderia fissirostris. 



Euglypha compressa. 

 Nebela tubulosa. 



flabellulum. 



carinata. 



marginata. 



2. The following species seem to be restricted to the drier 

 mosses : 



Am xb a rerrucosa ; 

 Diplophrys timida ; 

 Difflugia lucida ; 

 arcula ; 



Pontigulasia spiralis ; 

 Nebela lageniformis ; 



bigibbosa ; 

 Heleopera sylvatlca ; 



while Sphenoderia dentata appears much more abundantly in 

 them. 



3. The special abundance of " Filose " forms as compared with 

 the results of previous workers (West records 7 species, Murray 8, 

 Evans and Penard 19). 



4. The wide distribution of some species frequently regarded as 

 rather rare, e.g. Placocysta spinosa, and Sphenoderia fissirostris. 



5. The record of some species apparently for the first time for 

 this country e.g. Nebela longicollis, N. titbulata, N. bigibbosa, 

 Sphenoderia macrolepis, etc.
