  Only 
  two 
  specimens 
  of 
  this 
  species 
  were 
  taken. 
  One 
  bad 
  the 
  body 
  

   filled 
  with 
  rather 
  large 
  eggs, 
  dark 
  red, 
  with 
  a 
  purple 
  tinge, 
  and 
  with 
  a 
  

   darker 
  nucleus. 
  Our 
  specimens 
  agree 
  perfectly 
  with 
  Claparede's 
  

   description 
  of 
  Sphwrodorum 
  peripatus. 
  The 
  body 
  is 
  covered 
  by 
  a 
  very 
  

   delicate 
  membrane, 
  which 
  is 
  external 
  to 
  and 
  completely 
  covers 
  all 
  the 
  

   appendages 
  — 
  rami, 
  cirri, 
  papillae, 
  &c. 
  

  

  Just 
  within 
  each 
  dorsal 
  cirrus 
  is 
  a 
  second 
  spherule, 
  smaller 
  than 
  the 
  

   cirrus, 
  but 
  larger 
  than 
  the 
  other 
  papillae, 
  and 
  definite 
  in 
  position. 
  On 
  

   each 
  segment 
  there 
  are 
  three 
  series 
  of 
  papillae 
  attached 
  to 
  the 
  body 
  by 
  a 
  

   slender 
  cylindrical 
  stalk. 
  The 
  papillae 
  have 
  various 
  forms 
  — 
  spherical, 
  

   cylindrical, 
  or 
  even 
  cup-shaped, 
  in 
  which 
  case 
  the 
  margin 
  of 
  the 
  cup 
  is 
  

   fringed 
  (digitate). 
  

  

  Twenty-five 
  to 
  thirty 
  fathoms, 
  rocks, 
  shells, 
  hydroids, 
  &c. 
  

  

  Ephesia 
  minuta, 
  n. 
  sp. 
  

  

  (Pl. 
  IV, 
  Figs. 
  G4-GG.) 
  

  

  In 
  this 
  species 
  the 
  head 
  is 
  rounded 
  at 
  the 
  sides 
  and 
  above, 
  truncated 
  

   in 
  front, 
  nearly 
  straight 
  behind, 
  its 
  length 
  a 
  little 
  less 
  than 
  its 
  width. 
  

   One 
  pair 
  of 
  black 
  circular 
  eyes, 
  lateral, 
  median. 
  From 
  the 
  outer 
  angles, 
  

   above 
  and 
  below, 
  of 
  the 
  truncated 
  front 
  of 
  the 
  head 
  arise 
  antennae. 
  

   These 
  are 
  longer 
  than 
  the 
  head, 
  somewhat 
  swollen 
  along 
  their 
  inner 
  

   third, 
  then 
  conical 
  ; 
  their 
  inner 
  two-thirds 
  bearing 
  numerous 
  long 
  cylin- 
  

   drical 
  papillae, 
  so 
  long 
  that 
  the 
  antennae 
  seem 
  to 
  be 
  branched. 
  

  

  The 
  head 
  can 
  be 
  retracted 
  so 
  far 
  as 
  to 
  conceal 
  both 
  itself 
  and 
  the 
  an- 
  

   tennae. 
  Thehead 
  is 
  also 
  furnished 
  with 
  cylindrical 
  papillae, 
  shorter 
  than 
  

   those 
  on 
  the 
  antenna;. 
  One 
  of 
  the 
  papillae, 
  however, 
  arising 
  between 
  the 
  

   eyes 
  is 
  much 
  elongated 
  and 
  seems 
  almost 
  like 
  an 
  unpaired 
  antenna. 
  

  

  The 
  first 
  segment 
  bears 
  seta?, 
  but 
  has 
  a 
  pair 
  of 
  tentacular 
  cirri, 
  of 
  

   about 
  the 
  same 
  length 
  as 
  the 
  median 
  papilla 
  of 
  the 
  head, 
  and 
  in 
  all 
  re- 
  

   spects 
  similar 
  to 
  it. 
  

  

  The 
  dorsal 
  cirri 
  are 
  globular 
  (fig. 
  G4), 
  attached 
  to 
  the 
  body 
  by 
  a 
  nar- 
  

   row 
  neck. 
  There 
  is 
  a 
  transverse 
  series 
  of 
  these 
  globular 
  papillae, 
  10-12 
  

   in 
  number 
  on 
  each 
  segment, 
  with 
  numerous 
  smaller 
  globular 
  and 
  cylin- 
  

   drical 
  papilla?- 
  scattered 
  over 
  the 
  general 
  surface. 
  The 
  terminal 
  pa- 
  

   pilla? 
  at 
  the 
  summit 
  of 
  the 
  large 
  spheres, 
  described 
  by 
  Olaparede 
  for 
  

   Sphccrodrum 
  peripatus, 
  do 
  not 
  exist 
  in 
  this 
  species, 
  but 
  all 
  the 
  papilla?
