  spicules 
  in 
  the 
  cortex, 
  and 
  the 
  branches 
  arising 
  from 
  the 
  soft 
  joints. 
  

   It 
  has 
  no 
  special 
  connexion 
  with 
  Dr. 
  Gray's 
  group 
  Ellisclladce, 
  in 
  

   which 
  he 
  placed 
  it, 
  and 
  appears 
  to 
  have 
  been 
  overlooked 
  by 
  recent 
  

   writers. 
  It 
  is 
  distinguished 
  by 
  the 
  very 
  massive 
  form 
  of 
  the 
  Blatt- 
  

   keule 
  spicules 
  and 
  the 
  swelling 
  out 
  of 
  their 
  " 
  Blatt 
  " 
  into 
  rounded 
  

   bodies 
  with 
  scarcely 
  perceptible 
  edges.

  Both 
  this 
  and 
  the 
  following 
  are 
  small 
  species, 
  not 
  known 
  to 
  ex- 
  

   ceed 
  4 
  inches 
  in 
  height, 
  and 
  they 
  are 
  proportionally 
  slender 
  ; 
  they 
  

   do 
  not 
  exhibit 
  the 
  lateral 
  impression 
  on 
  the 
  branches 
  described 
  by 
  

   Dr. 
  Gray. 
  They 
  are 
  nearly 
  allied 
  to 
  each 
  other, 
  and 
  Mopsea 
  eri/thrcea 
  

   of 
  Ehrenberg 
  {I. 
  c), 
  from 
  the 
  lied 
  Sea, 
  must 
  be 
  referred 
  to 
  the 
  same 
  

   genus. 
  A 
  well-preserved 
  spirit-specimen, 
  61 
  millim. 
  (2^

   long, 
  and 
  some 
  fragments 
  represent 
  IF. 
  clirysanthus 
  in 
  this 
  collection 
  ; 
  

   they 
  are 
  of 
  the 
  normal 
  white 
  colour 
  with 
  lemon-yellow 
  zooids. 
  

   A 
  variety 
  occurs 
  in 
  the 
  British 
  Museum 
  in 
  which 
  the 
  cortex 
  also 
  is 
  

   yellow.

  Wrightella 
  coccinea. 
  

   Gray,

  p.

  This 
  species 
  is 
  distinguished 
  from 
  the 
  former 
  by 
  its 
  colour 
  and 
  by 
  

   the 
  cortical 
  spicules 
  being 
  somewhat 
  smaller 
  than 
  in 
  that 
  species. 
  

   Some 
  fragmentary 
  (but 
  spirit) 
  specimens 
  occur 
  here. 
  Gray 
  has 
  

   omitted 
  to 
  mention 
  a 
  fact 
  which 
  these 
  and 
  the 
  original 
  specimens 
  

   show, 
  that 
  the 
  verrucae 
  are 
  usually 
  yellow.

  Both 
  species 
  were 
  originally 
  described 
  from 
  this 
  locality, 
  where 
  

   they 
  were 
  collected 
  by 
  Prof. 
  E. 
  P. 
  Wright. 
  I 
  am 
  glad 
  to 
  have 
  this 
  

   opportunity 
  of 
  pointing 
  out 
  the 
  true 
  affinities 
  of 
  these 
  two 
  beautiful 
  

   little 
  species, 
  which 
  in 
  their 
  slender 
  proportions 
  probably 
  approach 
  

   the 
  beautiful 
  Psilacaharia 
  of 
  the 
  Australian 
  collection 
  more 
  nearly 
  

   than 
  any 
  other 
  described 
  species.
