  COLLECTIONS 
  FROM 
  MELANESIA. 
  

  

  have 
  a 
  somewhat 
  radiating 
  disposition 
  on 
  the 
  spire. 
  Eoth 
  speciineus 
  

   have 
  a 
  series 
  of 
  small 
  patches 
  around 
  tlie 
  periphery 
  of 
  the 
  body- 
  

   whorl 
  and 
  a 
  second 
  below 
  it 
  on 
  the 
  under 
  surface. 
  They 
  are 
  con- 
  

   siderably 
  smaller 
  than 
  those 
  described 
  by 
  Pischer, 
  but 
  may 
  not 
  be 
  

   full-grown 
  ; 
  this 
  is 
  probably 
  the 
  case, 
  as 
  the 
  umbilicus 
  is 
  more 
  

   open 
  than 
  in 
  the 
  shells 
  from 
  Lifu. 
  The 
  whorls 
  also 
  exhibit 
  little 
  or 
  

   no 
  trace 
  of 
  an 
  angle 
  above 
  the 
  middle.

  This 
  species 
  is 
  the 
  T. 
  tceniatus 
  of 
  Quoy 
  & 
  Gaimard, 
  1S34 
  (not 
  

   T. 
  tceniatus,

  1828), 
  and 
  Lahio 
  porcata 
  of 
  A. 
  Adams 
  is 
  only 
  a 
  

   slight 
  variety. 
  

  

  Philippi 
  (Con.-Cab. 
  p. 
  160) 
  is 
  inclined 
  to 
  consider 
  T. 
  zehra 
  merely 
  

   a 
  variation 
  of 
  T. 
  constrictus, 
  and 
  possibly 
  he 
  is 
  correct 
  ; 
  still 
  I 
  think 
  

   further 
  evidence 
  is 
  requisite 
  in 
  order 
  to 
  place 
  this 
  supposition 
  beyond 
  

   a 
  doubt.

  The 
  two 
  specimens 
  of 
  this 
  beautiful 
  species 
  from 
  Port 
  Molle 
  are 
  

   peculiar 
  in 
  having 
  four 
  spiral 
  lira; 
  instead 
  of 
  three 
  upon 
  the 
  upper 
  

   whorls, 
  and 
  those 
  beneath 
  the 
  periphery 
  of 
  the 
  last 
  rather 
  finer 
  than 
  

   in 
  the 
  Philippine 
  examples. 
  The 
  deep 
  suture 
  and 
  the 
  character 
  of 
  

   the 
  sculpture 
  rather 
  suggest 
  Perrinia 
  than 
  Thalotia 
  as 
  the 
  section 
  

   for 
  this 
  species.
