  must 
  be 
  referred 
  to 
  the 
  variety 
  cheverti, 
  not 
  only 
  are 
  the 
  hepatic 
  

   granules 
  entirely 
  absent, 
  but 
  also 
  the 
  front 
  has 
  not 
  the 
  faintest 
  

   trace 
  of 
  trilobation. 
  

  

  97. 
  Leucosia 
  craniolaris, 
  var. 
  laevimana. 
  (Plate 
  XXVI. 
  fig. 
  A.) 
  

  

  I 
  propose 
  thus 
  to 
  designate, 
  at 
  least 
  provisionally, 
  a 
  female 
  speci- 
  

   men 
  obtained 
  in 
  10 
  fms. 
  at 
  Friday 
  Island, 
  Torres 
  Straits 
  (No. 
  153), 
  

   which 
  is 
  distinguished 
  from 
  the 
  very 
  numerous 
  examples 
  of 
  

   L. 
  craniolaris 
  in 
  the 
  Museum 
  collection 
  by 
  the 
  absence 
  of 
  a 
  series 
  

   of 
  granules 
  on 
  the 
  inner 
  margin 
  of 
  the 
  palms 
  of 
  the 
  chelipedes. 
  

   The 
  carapace 
  is 
  narrower 
  than 
  is 
  usual 
  in 
  L. 
  craniolaris, 
  very 
  

   polished 
  and 
  shining, 
  and 
  has 
  two 
  white 
  spots 
  on 
  either 
  side 
  of 
  the 
  

   gastric 
  region. 
  The 
  notch 
  in 
  the 
  anterior 
  margin 
  of 
  the 
  thoracic 
  

   sinus 
  is 
  less 
  distinct 
  than 
  is 
  usual 
  in 
  L. 
  craniolaris. 
  A 
  second 
  

   specimen 
  from 
  Torres 
  Straits, 
  in 
  the 
  Museum 
  collection, 
  resembles 
  

   Dr. 
  Coppinger's 
  example 
  in 
  its 
  narrow 
  rhomboidal 
  carapace, 
  but 
  the 
  

   inner 
  margins 
  of 
  the 
  chelipedes 
  are 
  distinctly 
  granulated. 
  

  

  Specimens 
  of 
  Leucosia 
  craniolaris 
  are 
  in 
  the 
  British 
  Museum 
  from 
  

   Tranquebar( 
  OZcZ 
  Collection) 
  ; 
  Ceylon 
  (E. 
  W. 
  H. 
  Holchwortli) 
  ;

  Cantor); 
  Borneo 
  and 
  Chinese 
  seas 
  {coll. 
  H.M.S.

   Formosa 
  {Mattliew 
  Diclcson) 
  ; 
  Hong-Kong 
  {Dr. 
  W. 
  A. 
  Harland 
  and 
  

   W. 
  Stinipson). 
  

  

  98. 
  Myra 
  carinata, 
  Bell. 
  

  

  Flinders, 
  Clairmont, 
  N.E. 
  Australia. 
  A 
  fine 
  male 
  dredged 
  in 
  

   11 
  fms. 
  (No. 
  108) 
  seems 
  to 
  be 
  referable 
  to 
  this 
  species, 
  which 
  has 
  

   been 
  recorded 
  by 
  Mr. 
  Haswell 
  * 
  from 
  Cape 
  Grenville. 
  

  

  Specimens 
  are 
  in 
  the 
  British-Museum 
  collection 
  from 
  the 
  Celebes, 
  

   Macassar 
  {coll. 
  Dr. 
  Bleeker), 
  Philippines 
  {Cuming), 
  and 
  Hong- 
  

   Kong 
  {Dr. 
  W. 
  A. 
  Harland). 
  

  

  These 
  differ 
  slightly 
  among 
  themselves 
  in 
  certain 
  points, 
  as 
  e. 
  g. 
  

   the 
  relative 
  narrowness 
  of 
  the 
  carapace, 
  prominence 
  of 
  the 
  inner 
  

   and 
  upper 
  orbital 
  angles, 
  and 
  length 
  of 
  the 
  posterior 
  spines, 
  charac- 
  

   ters 
  that 
  may 
  be 
  of 
  some 
  importance 
  ; 
  but 
  large 
  series 
  are 
  needed 
  to 
  

   determine 
  with 
  certainty 
  the 
  distinctions 
  between 
  the 
  very 
  variable 
  

   species 
  of 
  this 
  genus.

  Four

  by 
  Mr. 
  Haswell 
  from 
  Cape 
  Grenville 
  and 
  New 
  South 
  Wales, 
  

   have 
  a 
  more 
  or 
  less 
  distinct 
  median 
  longitudinal 
  carina 
  on 
  the 
  

   carapace. 
  

  

  Of 
  M. 
  affinis
