  "The 
  name 
  Solariella 
  given 
  to 
  a 
  crag 
  fossil 
  (tertiary) 
  species 
  by 
  Searles 
  Wood, 
  which 
  

   he 
  afterwards 
  reunited 
  to 
  Margarita, 
  is 
  here 
  used 
  as 
  a 
  subgenus, 
  in 
  the 
  author's 
  sense, 
  for 
  

   Margaritae 
  with 
  large 
  crenated 
  umbilicus. 
  This 
  is 
  one 
  of 
  the 
  many 
  instances 
  in 
  which 
  the 
  

   North 
  Pacific 
  fauna 
  carries 
  out 
  the 
  ideas 
  of 
  the 
  English 
  crag.

  I,

  for 
  a 
  subgenus 
  of 
  Monilea, 
  with 
  which 
  these 
  shells 
  have 
  only 
  a 
  

   limited 
  affinity 
  : 
  and, 
  accordingly, 
  the 
  true 
  Sohriellae 
  have 
  been 
  reconstituted 
  as 
  part 
  of 
  

   Minolia. 
  A. 
  Ad. 
  That 
  gentleman, 
  however, 
  fully 
  accords 
  with 
  the 
  present 
  arrangement. 
  The 
  

   Sohriellae 
  are 
  known 
  from 
  Trochiscus, 
  and 
  from 
  all 
  forms 
  of 
  Solariadae, 
  by 
  the 
  normal 
  (not 
  

   inverted 
  ( 
  nuclear 
  whirls 
  f.^/r] 
  ,• 
  and 
  from 
  the 
  Solarids, 
  by 
  the 
  nacreous 
  texture. 
  

  

  "Dr. 
  Cooper's 
  very 
  lovely 
  species 
  of 
  a 
  very 
  lovely 
  group 
  may 
  possibly 
  prove 
  to 
  be 
  a 
  va- 
  

   riety 
  of 
  the 
  Japanese 
  'Minolia 
  aspecta 
  A. 
  Ad.' 
  ms. 
  in 
  Mus. 
  Cuming; 
  but, 
  until 
  more 
  speci- 
  

   mens 
  from 
  each 
  district 
  have 
  been 
  compared, 
  it 
  is 
  more 
  prudent 
  to 
  keep 
  them 
  separate. 
  It 
  

   seems 
  to 
  have 
  exhau.sted 
  the 
  powers 
  of 
  sculpture 
  on 
  its 
  graceful 
  habitation. 
  Under 
  the 
  micro- 
  

   scope, 
  the 
  sharp 
  transverse 
  lirulae, 
  mounting 
  over 
  the 
  keels, 
  dividing 
  the 
  interspaces, 
  and 
  even 
  

   ascending 
  the 
  wide 
  umbilicus, 
  are 
  eminently 
  beautiful. 
  Even 
  the 
  operculum 
  is 
  sculptured 
  with 
  

   delicate 
  waved 
  radiating 
  lines. 
  It 
  has 
  the 
  aspect 
  of 
  an 
  extremely 
  thin 
  Torinia, 
  with 
  a 
  funnel- 
  

   shaped 
  umbilicus. 
  This 
  is 
  not 
  only 
  bounded 
  by 
  a 
  granular 
  keel, 
  but 
  has 
  three 
  other 
  distant 
  

   spiral 
  lines 
  crossing 
  the 
  lirulae. 
  The 
  radiating 
  sculpture 
  is 
  more 
  distant 
  on 
  the 
  upper 
  whirls, 
  

   where 
  first 
  two, 
  then 
  three 
  keels 
  appear, 
  fenestrated 
  by 
  the 
  lirulae, 
  which 
  afterwards 
  become 
  

   much 
  closer, 
  and 
  are 
  sometimes 
  worn 
  away 
  behind 
  the 
  labrum."

  Pilsbry 
  (1889) 
  translated 
  Carpenter's 
  description 
  (1866)

  The 
  drawing 
  published 
  by 
  Dall 
  (1921) 
  is 
  

   apparently 
  a 
  figure 
  of 
  the 
  lectotypc, 
  but 
  it 
  is 
  not 
  exact 
  in 
  details. 
  The 
  longitudinal 
  ribs 
  are 
  

   stronger 
  than 
  in 
  the 
  Dall 
  drawing 
  as 
  may 
  be 
  seen 
  by 
  comparing 
  the 
  photograph 
  of 
  the 
  holo- 
  

   type 
  herein 
  included. 
  There 
  is 
  one 
  specimen 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  labelled 
  "Cotype 
  

   Cataline

  Since 
  there 
  would, 
  therefore, 
  have 
  been 
  more 
  than 
  one 
  type 
  at 
  some- 
  

   time, 
  the 
  existing 
  type 
  is 
  a 
  lectotype.
