﻿between 
  them. 
  In 
  spirit 
  they 
  are 
  tough 
  and 
  cartilaginous, 
  rather 
  over 
  

   an 
  inch 
  long 
  and 
  about 
  the 
  same 
  in 
  tlieir 
  greatest 
  width 
  at 
  the 
  base, 
  and 
  

   each 
  contains 
  only 
  a 
  single 
  embryo. 
  

  

  The 
  shells 
  when 
  extracted 
  from 
  the 
  capsules 
  are 
  an 
  inch 
  in 
  length, 
  

   consist 
  of 
  5k 
  whorls, 
  the 
  last 
  showing 
  the 
  commencement 
  of 
  the 
  colour- 
  

   markings 
  and 
  the 
  columellar 
  plaits 
  of 
  the 
  adult 
  shell. 
  

  

  Since 
  the

  was 
  written 
  Mr. 
  Jukes-Browne 
  has 
  received 
  from 
  

   Mr. 
  Banfield 
  a 
  photograph 
  of 
  a 
  more 
  complete 
  mass 
  of 
  egg-capsules. 
  It 
  

   has 
  very 
  much 
  the 
  form 
  of 
  an 
  elongate 
  fir-cone, 
  and 
  the 
  openings 
  in 
  it 
  

   appear 
  to 
  be 
  arranged 
  in 
  longitudinal, 
  slightly 
  oblique, 
  and 
  regular 
  rows, 
  

   the 
  lower 
  margin 
  of 
  each 
  opening 
  exhibiting 
  a 
  short 
  spike-like 
  projection 
  

   which 
  is 
  the 
  termination 
  of 
  a 
  ridge 
  upon 
  one 
  side 
  of 
  the 
  capsules.

  Specimens 
  of 
  this 
  snail 
  were 
  taken 
  on 
  

   3rd 
  January, 
  1909, 
  near 
  the 
  Gizeh 
  Pyramids, 
  where, 
  except 
  one 
  individual 
  

   found 
  on 
  a 
  stone 
  covered 
  with 
  lichen, 
  none 
  were 
  seen 
  far 
  from 
  the 
  traces 
  

   of 
  higher 
  vegetation, 
  at 
  that 
  time 
  dried 
  up. 
  Three 
  examples 
  were 
  kept 
  

   alive 
  at 
  Mortehoe 
  in 
  Devon 
  from 
  the 
  first 
  week 
  in 
  May 
  till 
  12th 
  September 
  

   of 
  the 
  same 
  year, 
  when 
  they 
  died 
  seemingly 
  from 
  excess 
  of 
  moisture 
  in 
  

   the 
  air 
  and 
  their 
  food, 
  which 
  was 
  principally 
  lettuce. 
  They 
  ate 
  sparingly 
  

   of 
  the 
  leaf 
  of 
  cauliflower 
  and 
  of 
  a 
  bean, 
  and 
  consumed 
  with 
  avidity 
  the 
  

   petals 
  of 
  a 
  Niphetos 
  rose, 
  but 
  did 
  not 
  appear 
  to 
  care 
  for 
  those 
  of 
  other 
  

   species. 
  They 
  liked 
  the 
  petals 
  of 
  calceolaria, 
  and 
  ate 
  those 
  of 
  pink 
  

   carnations, 
  but 
  not 
  those 
  of 
  the 
  red. 
  They 
  were 
  further 
  offered 
  petals 
  

   and 
  leaves 
  of 
  borage 
  and 
  balsam, 
  petals 
  of 
  Schizanthus, 
  leaves 
  of 
  celery, 
  

   sedium, 
  saxifrages, 
  turnip, 
  strawberry, 
  Potentilla, 
  dandelion, 
  and 
  spinach, 
  

   but 
  did 
  not 
  care 
  for 
  any 
  of 
  them.

  — 
  

   A 
  short 
  time 
  since 
  Mr. 
  F. 
  F. 
  Laidlaw 
  forwarded 
  for 
  determination 
  some 
  

   specimens 
  of 
  Puidium 
  from 
  Lochan 
  a' 
  Chait, 
  a 
  small 
  tarn 
  situated 
  to 
  

   the 
  north 
  of 
  Loch 
  Tay 
  on 
  the 
  flanks 
  of 
  Ben 
  Lawers, 
  Perthshire, 
  at 
  an 
  

   elevation 
  of 
  2250 
  feet. 
  These 
  proved 
  to 
  be 
  examples 
  of 
  P. 
  Steenbuchii, 
  

   Morch, 
  a 
  northern 
  form, 
  which 
  had 
  hitherto 
  only 
  been 
  found 
  fossil 
  in 
  

   these 
  islands. 
  Thus 
  it 
  had 
  been 
  recognized 
  in 
  Holocene 
  deposits 
  at 
  

   Shand 
  Street, 
  Tooley 
  Street 
  (Surrey), 
  Gayfield 
  (Edinburgh), 
  and 
  in 
  a 
  Shell 
  

   Marl 
  at 
  Inchiquin 
  (co. 
  Clare, 
  Ireland) 
  ; 
  whilst 
  in 
  the 
  Pleistocene 
  it 
  

   occurs 
  in 
  the 
  Crayford-Erith 
  shell-beds, 
  and 
  in 
  the 
  freshwater 
  beds 
  of 
  

   the 
  Forest 
  Bed 
  at 
  West 
  Runton 
  (Norfolk). 
  

  

  A 
  little 
  later 
  Mrs. 
  Longstaff 
  sent 
  me 
  some 
  Plsidia 
  from 
  the 
  Lake 
  

   District. 
  These 
  included 
  examples 
  of 
  an 
  oval 
  form 
  of 
  P. 
  Steenbuchii 
  

   from 
  Abbey 
  Holme 
  in 
  Cumberland, 
  and 
  Patterdale 
  on 
  the 
  borders 
  of 
  

   Westmorland, 
  that 
  had 
  been 
  collected 
  twenty- 
  five 
  years 
  ago. 
  

  

  The 
  following 
  species 
  in 
  her 
  collection 
  were 
  also 
  new, 
  in 
  name 
  at 
  

   least, 
  to 
  the 
  district, 
  viz. 
  : 
  — 
  Pisidium 
  subtruncatum 
  from 
  Blaithwaite 
  

   and 
  near 
  Carlisle, 
  P. 
  obtvsale 
  from 
  Dalston 
  and 
  Wreay, 
  and 
  P. 
  personatum 
  

   from 
  Rockclifte. 
  The 
  last-named 
  species 
  has 
  also 
  been 
  received 
  from 
  

   Captain 
  W. 
  J. 
  Farrer, 
  from 
  Bassenthwaite 
  Lake, 
  whilst 
  the 
  same 
  observer 
  

   has 
  collected 
  from 
  ditches 
  thereabout 
  P. 
  pulchellum, 
  another 
  new 
  record 
  

   for 
  the 
  Cumljerland 
  fauna.
