  Orthoceras 
  nuntioides, 
  sp. 
  nov. 
  

   Plate

   A 
  strongly 
  annulated 
  shell 
  of 
  the 
  type 
  of 
  Orthoceras 
  nun- 
  

   tium, 
  0. 
  crotalum, 
  etc., 
  possessing 
  the 
  same 
  style 
  of 
  external 
  

   ornamentation, 
  but 
  the 
  longitudinal 
  elevated 
  striae 
  are 
  much 
  

   finer 
  than 
  in 
  any 
  species 
  heretofore 
  described. 
  These 
  striae 
  are 
  

   of 
  subequal 
  size 
  and 
  are 
  closely 
  crowded, 
  the 
  appearance 
  of 
  fine 
  

   intercalary 
  striae 
  being 
  infrequent. 
  Yery 
  faint 
  concentric 
  stria- 
  

   tions 
  are 
  visible 
  on 
  certain 
  portions 
  of 
  the 
  surface. 
  The 
  original 
  

   specimen 
  retains 
  nine 
  strong, 
  distant 
  annulations, 
  which 
  are 
  

   more 
  conspicuous 
  than 
  in 
  0. 
  nuntium; 
  and 
  also 
  the 
  apertural 
  

   extremity 
  of 
  the 
  shell, 
  upon 
  which 
  no 
  annulations 
  exist. 
  The 
  

   specimen 
  is 
  from 
  the 
  calcareous 
  Marcellus 
  shales 
  in 
  the 
  village 
  of 
  

   Chapinville, 
  Ontario 
  county.

   This 
  species, 
  we 
  believe, 
  has 
  not 
  heretofore 
  been 
  recognized 
  

   except 
  in 
  the 
  faunas 
  from 
  which 
  it 
  was 
  originally 
  described, 
  

   the 
  Corniferous 
  limestone, 
  but 
  a 
  very 
  characteristic 
  example 
  has 
  

   been 
  taken 
  from 
  the 
  lower 
  limestone 
  of 
  the 
  Marcellus 
  shales 
  at 
  

   854 
  feet 
  in 
  the 
  Shaft, 
  where 
  it 
  is 
  associated 
  with 
  other 
  Cornifer- 
  

   ous 
  species, 
  Chonetes 
  lineata, 
  Cmlospira 
  Camilla, 
  etc. 
  

  

  Orthoceras

   Plate

   Tube 
  with 
  numerous 
  subequidistant, 
  broad 
  and 
  low 
  annula- 
  

   tions, 
  which 
  are 
  crossed 
  by 
  fine 
  sharp 
  concentric 
  elevated 
  striae. 
  

   These 
  are 
  traversed 
  by 
  very 
  fine, 
  straight, 
  longitudinal 
  striae 
  of 
  

   about 
  the 
  same 
  size, 
  and 
  the 
  intersection 
  of 
  the 
  two 
  series 
  covers 
  

   the 
  surface 
  with 
  minute 
  fenestrules 
  measuring 
  about 
  2 
  mm. 
  on 
  

   the 
  edge. 
  These 
  spaces 
  are 
  traversed 
  by 
  exceedingly 
  fine 
  concentric 
  

   lines, 
  visible 
  only 
  under 
  considerable 
  magnification. 
  The 
  striae 
  

   are 
  equally 
  developed 
  on 
  annulations 
  and 
  interspaces, 
  and 
  their 
  

   intersections 
  are 
  elevated 
  into 
  low 
  nodes 
  or 
  points 
  which 
  are 
  

   visible 
  when 
  the 
  lines 
  are 
  abraded. 
  One 
  of 
  the 
  specimens 
  

   referred 
  to 
  the 
  species, 
  has 
  the 
  transverse 
  lines 
  highly 
  developed 
  

   while 
  the 
  series 
  of 
  vertical 
  lines 
  is 
  very 
  obscure.
