  Since 
  the 
  non-mariue 
  mollusca 
  of 
  these 
  three 
  comital 
  divisions 
  have 
  

   not 
  been 
  collected 
  extensively, 
  we 
  have 
  thouglit 
  it 
  advisable 
  to 
  put 
  on 
  

   record 
  the 
  results 
  of 
  the 
  collecting 
  by 
  one 
  of 
  us 
  (K.H.J.) 
  therein 
  

   during 
  the 
  past 
  few 
  years. 
  

  

  East 
  Ross. 
  

  

  In 
  this 
  vice-comital 
  division 
  only 
  a 
  small 
  area 
  in 
  the 
  immediate 
  

   vicinity 
  of 
  Cromarty 
  Firth 
  was 
  examined 
  in 
  1912-13, 
  and 
  again 
  in 
  

   1915-16. 
  Owing 
  to 
  the 
  conditions, 
  collecting 
  was 
  only 
  possible 
  for 
  

   short 
  and 
  broken 
  periods, 
  but 
  a 
  fair 
  number 
  of 
  species 
  were 
  obtained. 
  

   At 
  Cromarty 
  areas 
  of 
  rich 
  and 
  well-cultivated 
  alluvial 
  soil 
  surround 
  

   much 
  of 
  tlie 
  Firth, 
  but 
  a 
  few 
  miles 
  inland 
  these 
  give 
  place 
  to 
  rough 
  

   moorland 
  and 
  heather-clad 
  hills. 
  At 
  Alness 
  and 
  Invergordon, 
  both 
  on 
  

   the 
  Firth, 
  are 
  woods 
  of 
  deciduous 
  trees, 
  for 
  the 
  most 
  part 
  of 
  consider- 
  

   able 
  size; 
  but 
  on 
  the 
  hills 
  conifers 
  alone 
  seem 
  able 
  to 
  maintain 
  

   themselves. 
  At 
  Alness 
  the 
  woods 
  are 
  chiefly 
  situate 
  on 
  the 
  banks 
  of 
  

   the 
  river 
  of 
  tlie 
  same 
  name.
