Western  Atlantic  Species  of  the 

Genus  Holocentrus 

Loren  P.  Woods 

Curator,  Division  of  Fishes 

Among  the  fishes  collected  in  the  Gulf  of  Mexico  by  the  United 
States  Fish  and  Wildlife  Service  M/V  Oregon  during  the  years 
1950-53,  there  were  17  specimens  of  Holocentrus  taken  from  the 
bottom  in  otter  trawls  in  depths  from  29  to  60  fathoms.  These 
could  not  be  determined  by  using  the  key  of  Jordan  and  Evermann 
(1896,  p.  848)  or  that  of  Parr  (1930,  pp.  34-35)  or  by  comparing 
them  with  identified  specimens  in  the  Chicago  Natural  History 
Museum  collection.  It  was  therefore  necessary  to  review  the  litera- 
ture, especially  of  species  that  have  long  been  in  synonymy,  and 
re-examine  all  available  specimens.  These  studies  have  resulted  in 
the  reduction  of  two  species  to  synonymy  (osculus  and  sanctipauli) , 
recognition  of  one  previously  synonymized  species  (rufus),  and 
description  of  one  new  species  (bullisi). 

METHODS 

Counts  and  measurements  have  been  made  according  to  standard 
practice  as  outlined  by  Hubbs  and  Lagler  (1947,  pp.  8-15),  except 
when  noted  otherwise.  All  rudiments  of  gill  rakers  are  included  in 
the  counts  given.  The  length  of  the  lower  jaw  was  measured  from 
the  posterior  edge  of  the  angular  to  the  anterior  tip  of  the  dentary, 
that  of  the  upper  jaw,  with  mouth  closed  and  bones  in  normal 
position,  from  the  anterior  tip  of  the  premaxillary  to  the  posterior 
margin  of  the  maxillary.  The  head  length  was  measured  from  the 
anterior  tip  of  the  premaxillary  to  the  tip  of  the  longest  opercular 
spine,  that  of  the  preopercular  spine  from  its  tip  to  the  dorsal  angle 
with  the  anterior  margin  of  the  preopercle,  that  is,  to  the  margin  of 
the  scales  at  the  lower  posterior  corner  of  the  cheek.

DISCUSSION 

Dr.  Edward  M.  Nelson,  Assistant  Professor  in  Anatomy,  Stritch 
School  of  Medicine,  Loyola  University,  simultaneously  has  been 
studying  the  structure  and  relations  of  the  air  bladder  to  the  auditory 
bullae  in  the  entire  family  Holocentridae  (Nelson,  this  volume,  pp. 
121-137) .  His  observations  have  been  referred  to  below,  but  without 
details  or  figures.  It  is  considered  not  entirely  inconsistent  with 
Nelson's  data  to  recognize  the  four  lines  of  development  that  can 
be  distinguished  within  the  genus  Holocentrus  as  subgenera  as 
follows,  although  on  the  basis  of  internal  structures  Nelson  has 
distinguished  only  two  lines,  Holocentrus  and  Adioryx. 

Flammeo  Jordan  and  Evermann 

Flammeo   Jordan   and    Evermann,    1898,   Bull.   U.  S.   Nat.   Mus.,   no.   47, 
p.  2871  (type,  Holocentrus  marianus). 

The  species  referred  to  Flammeo  have  the  dorsal  fin  spines  X, 
I,  the  last  spine  of  the  dorsal  usually  longer  than  the  tenth,  separated 
from  it  although  attached  at  its  base  by  a  membrane  and  more  or 
less  closely  joined  with  the  first  dorsal  soft  ray,  the  body  elongate, 
and  the  lower  jaw  extending  beyond  the  upper.  This  subgenus 
contains  the  species  marianus,  sammara,  laevis,  opercularis,  and 
scythrops. 

Sargocentron  Fowler 

Sargocentron  Fowler,  1904,  Proc.  Acad.  Nat.  Sci.  Phila.,  55:  235  (type,  Holo- 
centrus leo). 

Sargocentron  includes  species  of  large  size,  the  body  deep  and 
squarish,  the  spiny  dorsal  fin  high.  The  species  grouped  here  are 
leo  Cuvier  and  Valenciennes  (=spinifer),  tieroides,  spinosissimus, 
praslin,  and  ensifer. 

Adioryx  Starks 

Adioryx  Starks,  1908,  Science,  28:  614  (type,  Holocentrus  suborbitalis). 

Adioryx  includes  the  intermediate  residue  of  species,  some 
grading  toward  Flammeo  as  do  xantherythrus,  coruscus,  and  bullisi, 
and  others  forming  a  group  more  typical  for  Adioryx,  such  as  subor- 
bitalis, vexillarius,  punctatissimus,  lacteoguttatus,  microstomus,  Here, 
and  hastatus. 

Holocentrus  Scopoli 

Holocenthrus  Scopoli,  1777,  Int.  Hist.  Nat.,  p.  499  (misprint  for  Holocentrus 
after  Gronow's  Holocentrus  maxilla). 


WOODS:  SPECIES  OF  HOLOCENTRUS  93 

Holocentrus  contains  only  the  species  ascensionis  and  rufus.  It 
is  characterized  externally  by  having  the  dorsal  spines  more  nearly 
of  equal  length,  produced  anterior  dorsal  and  anal  soft  rays,  very 
elongate  caudal  lobes,  and  the  upper  lobe  much  longer  than  the 
lower;  internally  by  the  tubular  structure  of  the  auditory  bulla  with 
its  opening  directed  posteriorly  and  the  swim  bladder  with  a  mem- 
branous area  on  either  side  on  its  anterior  face  (Nelson,  this  volume, 
pp.  121-137). 

Three  of  these  groups  are  found  in  the  Atlantic:  subgenera 
Holocentrus,  Adioryx,  and  Flammeo.  The  three  in  the  Pacific  are 
Adioryx,  Flammeo,  and  Sargocentron. 

Mr.  Norman  Wilimovsky  has  suggested  that  a  number  of  generic 
names  take  priority  over  Adioryx  Starks,  1908,  type  Holocentrus 
suborbitalis  Gill.  I  have  re-examined  the  descriptions,  wherein 
numerous  names  have  been  conferred  on  larval  and  post-larval 
Holocentridae  and  others,  and  find  as  follows: 

Rhynchichthys  Valenciennes  (Cuvier  and  Valenciennes,  1831, 
p.  504),  type  R.  pelamidis  Valenciennes,  from  the  Indian  Ocean, 
dorsal  X,  I,  12.  The  type  is  obviously  a  larval  fish  and  we  have  at 
hand  larval  specimens  of  Myripristis  occidentalis  with  preopercular 
spines  almost  as  well  developed  as  those  figured  for  R.  pelamidis 
(Cuvier  and  Valenciennes,  1831,  pi.  208) .  Further,  it  is  characteristic 
of  Myripristis  to  have  the  dorsal  X,  I.  The  count,  anal  IV,  12, 
given  by  Valenciennes  could  not  refer  to  any  known  species  of 
Holocentrus,  but  the  number  12  is  characteristic  of  Myripristis. 
Rhynchichthys  pelamidis  Valenciennes  is  therefore  referred  to  syn- 
onymy of  the  genus  Myripristis. 

Rhinoberyx  Gill  (1862,  p.  237),  type  Rhynchichthys  brachyrhynchus 
Bleeker,  from  Amboina.  This  species  is  figured  in  Bleeker's  Atlas 
(9,  pi.  357,  fig.  1).  It  has  the  appearance  of  a  small  Myripristis. 
It  has  no  preopercular  spine,  the  dorsal  is  X,  I,  13  or  14  and  the 
anal  is  IV,  11  or  12,  the  anal  spines  are  more  like  those  of  Myripristis 
in  size  and  proportion,  and  the  number  of  anal  rays  is  applicable 
only  to  species  of  Myripristis.  Rhinoberyx  chryseus  Cope  (1870,  p. 
464,  fig.  2)  is  a  synonym  of  Myripristis  jacobus. 

Rhamphoberyx  Gill  (1863,  p.  87),  type  R.  poecilopus  Gill,  from 
Cape  San  Lucas,  Baja  California,  Mexico.  Specimens  on  which 
this  genus  and  species  were  based  were  "1M  to  2%  inches  long." 
From  the  description  it  is  evident  that  the  specimens  were  larval 
or  were  just  transforming.  The  spine  at  the  angle  of  the  preoper- 
culum  is  "not  essentially  enlarged,  but  simply  forms  the  angle  at 


94  FIELDIANA:  ZOOLOGY,  VOLUME  37 

the  preoperculum."  Counts  given  are  dorsal  X,  I,  14;  anal  IV,  11. 
No  species  of  Holocentrus  known  to  me  has  11  anal  rays.  Gilbert 
and  Starks  (1904,  p.  65)  have  placed  poecilopus  in  the  genus  Myri- 
pristis, and  Hildebrand  (Meek  and  Hildebrand,  1923,  p.  296),  who 
had  access  to  Gill's  types,  apparently  agreed  with  Gilbert  and  Starks, 
although  Meek  and  Hildebrand  had  no  specimens  of  poecilopus  from 
Panama.  The  other  species  placed  in  this  genus  by  Gill  (1863,  p. 
88),  Rhamphoberyx  leucopus  Gill,  has  dorsal  X,  I,  14;  anal  IV,  12. 
No  preopercular  spine  is  mentioned  in  the  original  description. 
Hildebrand  (Meek  and  Hildebrand,  1923,  p.  295)  has  placed  leucopus 
in  the  synonymy  of  Myripristis  occidentalis. 

Neomyripristis  Castelnau  (1873,  p.  99),  type  A7.  amaenus  Cas- 
telnau,  from  Torres  Strait,  Australia,  is  described  as  being  very  near 
to  Myripristis  but  with  different  teeth;  preopercular  without  a 
spine;  dorsal  X,  I,  15;  anal  IV,  14;  opercle  with  one  long  spine, 
below  which  are  two  short  spines.  All  of  these  characters  are  those 
of  Myripristis  rather  than  Holocentrus. 

The  original  description  of  the  genus  Neoniphon  Castelnau 
(1875,  p.  4),  type  A7.  armatus,  from  Cape  York,  Australia,  is  stated 
to  have  counts  as  follows:  dorsal  XI,  I,  12;  anal  III,  9;  pectoral  15; 
pel  vies  7;  scales  over  38-40.  The  color,  with  a  large  black  spot  on 
membranes  between  the  first  three  dorsal  spines,  and  numerous 
round  spots  on  cheek  and  body,  forming  irregular  lengthwise  lines; 
the  proportions;  and  the  counts,  except  for  the  number  of  anal 
spines,  along  with  the  mention  of  lower  jaw  being  larger  than  upper, 
all  agree  closely  with  Holocentrus  sammara  Forskal.  The  chief 
difficulty  is  that  the  size  is  stated  to  be  nearly  17  inches  (470  mm.) 
and  the  largest  sammara  of  which  I  can  find  a  record  is  267  mm. 
(about  10%  inches).  Neoniphon  hasta  De  Vis  (1885,  p.  537),  from 
Queensland  (dorsal  XI,  I,  12;  anal  III,  7;  lateral  line  40),  has  two 
long  spines  at  the  angle  of  the  preopercle;  the  black  blotch  on  the 
dorsal  membranes  seems  to  be  identical  with  that  of  armatus. 
Both  species  have  been  recognized  by  McCulloch  (1929,  pp.  134- 
135).  It  appears  likely  that  both  of  these  species  are  synonyms 
of  H.  sammara,  a  species  ranging  from  the  Red  Sea  to  the  Tuamotus 
and  abundant  in  the  Sunda  area  and  New  Guinea.  H.  sammara  is 
not  reported  from  Australia  although  it  should  certainly  occur  along 
the  northern  shore  and  the  northern  portion  of  the  eastern  shore  of 
Australia.  At  any  rate  it  is  fairly  certain  that  both  species  described 
under  Neoniphon  belong  to  the  Flammeo  group  and  if  so  the  name 
Neoniphon  has  priority  over  Flammeo.    However,  it  appears  to  be 


WOODS:  SPECIES  OF  HOLOCENTRUS  95 

more  sensible  to  continue  to  use  the  name  Flammeo  Jordan  and 
Evermann  (1898,  p.  2871),  based  as  it  is  on  a  well-known  species 
widely  used  in  the  literature,  rather  than  to  replace  it  with  a  name 
based  on  a  species  whose  status  is  uncertain. 

Harpage  De  Vis  (1884,  p.  447),  type  H.  rosea  De  Vis,  from  the 
South  Sea  Islands.  Dorsal  XII,  I,  14;  anal  III,  11,  lateral  line  scales 
42^,  "preopercle  scarcely  spiniferous,  with  short  bifid  spine  at 
angle."  The  short  preopercular  spine,  the  structure  of  the  dorsal 
and  the  number  of  the  anal  rays,  and  the  premaxillary  overhanging 
the  mandible  relate  this  species  to,  or  identify  it  with,  Holotrachys, 
as  suggested  by  Jordan  and  Seale  (1906,  p.  223).    H.  lima  has  dorsal 

XII,  15;  anal  IV,  11;  lateral  line  scales  43^;  and  bears  a  short 
spine  at  the  angle  of  the  preopercle.  The  short  first  anal  spine  may 
have  been  overlooked  by  De  Vis.  Nelson  has  found  H.  lima  to  be 
a  specialized  form  of  the  Myripristis  branch. 

Beanea  Steindachner  (1902,  p.  337),  type  B.  trivittata  Stein- 
dachner,  from  the  Red  Sea,  may  not  even  belong  to  the  family 

Holocentridae.  "D.  VII-I,  9;  A.  IV,  8;  P^  I,  5;  1.  lat.  25^."  All 
members  of  this  family  of  which  I  can  find  a  description  have  X,  I, 
XI,  or  XII  dorsal  spines  and  29  or  more  lateral  line  scales;  further, 
all  have  more  than  5  soft  rays  in  the  pelvic  fin.  The  type  of  Beanea 
was  a  small  specimen  (larval?)  30.6  mm.  in  length.  It  is  described 
as  having  the  body  form  of  Myripristis,  and  the  "border  of  the 
preopercle  and  lower  horizontal  part  of  the  forward  arm  of  the  same 
bone  entirely  sharply  toothed."  No  mention  is  made  of  a  spine 
at  the  angle  of  the  preopercle  that  is  characteristic  of  Holocentrus. 

Sargocentron  Fowler  (1904,  p.  235)  was  proposed  as  a  subgenus 
for  Holocentrus  leo  Cuvier,  a  species  that  I  believe  to  be  a  synonym 
of  H.  spinifer  Forskal.  The  name  Sargocentron  is  used  in  this  paper 
in  the  sense  I  believe  it  was  proposed,  namely,  as  a  subgenus  to 
include  large,  rectangular-bodied  species  with  "margin  of  preopercle 
coarsely  serrated."    (See  p.  92  for  list  of  such  species.) 

A  recently  proposed  genus  Beloholocentrus  Fowler  (1944,  p.  100), 
type  B.  atractus  Fowler  from  Courtown  Key  (12°  24'  N.,  81°  28'  W.), 
Caribbean  Sea,  appears  to  be  based  on  young  that  have  been  de- 
scribed by  Bean  (1906,  p.  42,  fig.  2)  as  Holocentrus  meeki  (=  Holo- 
centrus rufus)  and  the  "Rhynchichthys"  stage  of  H.  ascensionis. 

Various  names  proposed  for  subgenera  by  Whitley  (1933,  pp. 
68-69),  namely,  Cephalofarer  (type  H.  siccifer),  Faremusca  (type 
H.  punctatissimus) ,  and  Kutaflammeo  (type  H.  tahiticum)  do  not 


96 


FIELDIANA:  ZOOLOGY,  VOLUME  37 


enter  into  the  question  of  priority  of  names  used  herein.  H.  sicci- 
fer  is  a  synonym  of  H.  vexillarius,  which  along  with  punctatissimus 
fits  very  well  into  the  subgenus  Adioryx. 

The  remaining  genera  of  this  family,  Myripristis,  Corniger,  Holo- 
trachys,  Plectrypops,  Ostichthys,  and  the  fossil  genera  are  considered 
well  enough  known  or  far  enough  removed  from  this  group  to  have 
no  bearing  on  the  divisions  within  the  genus  Holocentrus  and  require 
no  further  discussion.

100  FIELDIANA:  ZOOLOGY,  VOLUME  37 

toral  fin  3.60-4.97,  length  of  pelvic  fin  4.47-5.53,  length  of  upper 
caudal  lobe  3.49-3.73,  length  of  lower  caudal  lobe  3.53-3.99,  all  in 
standard  length. 

Third  anal  spine  very  long,  its  tip  reaching  from  base  of  caudal 
rays  to  fork  of  caudal;  lower  jaw  projecting  beyond  upper;  maxillary 
reaching  from  anterior  margin  of  pupil  to  middle  of  pupil;  last  dorsal 
spine  nearer  to  first  dorsal  soft  ray  than  to  penultimate  spine; 
margin  of  premaxillary  groove  smooth;  opercular  spines  short  and 
heavy,  of  equal  length  or  with  upper  spine  slightly  enlarged;  profile 
nearly  straight. 

Color  completely  faded  in  all  available  specimens. 

Remarks. — Mrs.  M.  M.  Dick,  Museum  of  Comparative  Zoology, 
has  very  kindly  re-examined  Poey's  types  of  H.  rostratum,  MCZ 
10969,  two  specimens,  142  and  150  mm.  standard  length.  These 
specimens  are  apparently  correctly  referred  to  the  synonymy  of 
marianus  as  was  done  by  Howell-Rivero  (1938,  p.  183).  Their  fin 
ray  and  scale  counts  are  in  agreement  with  this  species;  the  only 
differences  noted  are  the  slightly  shorter  maxillary  (2.52  and  2.54) 
— but  the  maxillary  reaches  to  the  center  of  the  pupil — and  the 
shorter  third  anal  spine  (2.45  to  2.48).  This  latter  difference  is 
probably  because  of  a  difference  in  method  of  measuring.  The 
other  characters  of  serrae  and  spines  on  head  bones,  especially  oper- 
cular spines,  and  projecting  lower  jaw  are  characteristic  of  marianus. 

Dr.  Edward  M.  Nelson  has  found  no  differences  in  the  structure 
of  the  swim  bladder  and  auditory  bulla  in  species  referred  to  Flammeo 
(F.  sammara,  F.  laevis,  F.  scythrops,  F.  opercularis)  and  Adioryx 
suborbitalis  or  Holocentrus  coruscus,  vexillarius  and  numerous  Pacific 
species  referred  to  the  genus  Holocentrus.  It  is  therefore  proposed 
to  recognize  Flammeo  as  a  subgenus  of  Holocentrus  on  the  basis  of 
its  peculiar  dorsal  (X,  I)  and  protruding  lower  jaw.

Measurements  are  based  on  25  specimens  from  Bermuda,  St. 
Croix,  and  Brazil,  58  to  191  mm. 

Description. — Dorsal  fin  rays  XI,  15  (rarely  14  or  16) ;  anal  rays 
IV,  10;  pectoral  rays  ii,  13  to  15  (usually  ii,  14);  pelvics  I,  7;  scales 
in  lateral  line  bearing  tubes  46  to  51,  3  3/2  between  lateral  line  and 
origin  of  dorsal,  8  between  lateral  line  and  anal  opening;  gill  rakers 
on  first  arch  8  on  upper  limb,  one  at  angle,  14  or  15  on  lower  limb, 
total  23  or  24. 

Depth  of  body  2.69-3.13,  length  of  head  2.80-3.17,  length  of 
snout  11.8-15.3,  diameter  of  eye  6.35-9.45,  width  of  interorbital 
14.0-19.2,  length  of  upper  jaw  6.62-7.37,  length  of  lower  jaw  5.11- 
5.84,  length  of  preopercular  spine  16.0-18.7,  depth  of  caudal  pe- 
duncle 11.5-13.9,  length  of  caudal  peduncle  5.1-6.31,  length  of 
fourth  dorsal  spine  6.06-7.2,  length  of  third  anal  spine  5.23-6.52, 
length  of  pectoral  fin  4.32-4.93,  length  of  pelvic  fin  3.01-3.60,  length 
of  upper  caudal  lobe  2.60-3.93,  length  of  lower  caudal  lobe  2.97-4.03, 
all  in  standard  length. 

Body  deeper  than  in  H.  rufus  except  in  small  specimens;  mouth 
large,  upper  jaw  reaching  posteriorly  to  below  center  of  pupil  or 
beyond;  lower  jaw  generally  not  extending  anterior  to  upper  in 
small  specimens,  in  large  specimens  even  with  or  slightly  protruding; 
anterior  soft  rays  of  dorsal  and  anal  greatly  elongate;  upper  caudal 
lobe  considerably  longer  than  lower. 

Color. — In  alcohol,  essentially  as  in  H.  rufus  (q.v.)  except  spiny 
dorsal  membranes  lacking  distinct  white  spot  distally,  distal  portion 
instead  with  a  wedge  pale  or  dusky  colored  (green  to  greenish 
brown  in  living  specimens). 

Remarks. — This  species  may  usually  be  distinguished  from  rufus 
by  the  lower  number  of  tube-bearing  scales  in  the  lateral  line.  Since 
ascensionis  occasionally  has  51  scales,  it  is  necessary  to  rely  on 
measurements.  H.  ascensionis  always  has  a  larger  mouth  (measure- 
ments of  both  upper  and  lower  jaws)  and  in  all  except  specimens 
70  mm.  or  less  a  much  shorter  preopercular  spine.  When  specimens 
of  the  same  size  of  both  ascensionis  and  rufus  are  measured  and 
compared,  there  is  no  difficulty  in  distinguishing  all  specimens  (see 
tables  and  comparative  measurements  under  H.  rufus) .  The  species 
are  very  similar  in  characters  but  are  not  geographic  subspecies  since 
ascensionis  ranges  from  Brazil,  Panama,  and  the  West  Indies  to 
Bermuda,  while  H.  rufus  is  also  found  in  all  of  these  localities  except 
Brazil.  I  have  not  been  able  to  examine  specimens  of  ascensionis 
from  West  Africa  or  Ascension  Island.    Osbeck's  original  description 


WOODS:  SPECIES  OF  HOLOCENTRUS  103 

did  not  give  the  number  of  lateral  line  scales  (at  least  in  the  1771, 
English  edition,  available  to  me).  Giinther's  description  of  H. 
sanctipauli  records  48  lateral  line  scales  and  this  is  in  accordance 
with  my  findings  on  specimens  from  Brazil. 

We  have  one  small  specimen  from  St.  Croix  that  has  the  preoper- 
cular  spine  forked  on  one  side  as  in  sanctipauli;  on  the  other  side 
the  spine  is  broken. 

One  larval  specimen  of  ascensionis  (61  mm.)  from  St.  Croix  was 
examined;  it  is  similar  to  "meeki"  in  most  respects  but  is  deeper- 
bodied  and  has  48  and  49  tubed  lateral  line  scales.  We  have  also 
one  specimen  from  Puerto  Rico  completely  transformed  at  52 
mm.  This  specimen  has  47  scales  and  in  proportions  closely  re- 
sembles larger  ascensionis. 

H.  productum  Poey  was  based  on  a  specimen  68  mm.  long.  The 
counts  given  in  the  original  description  (dorsal  XI,  15;  anal  IV,  10) 
agree  with  ascensionis. 

I  have  examined  a  specimen,  USNM  37428,  56  mm.  standard 
length,  one  of  Poey's  specimens  and  labeled  as  the  type  of  productum. 
There  are,  however,  a  number  of  discrepancies  between  this  specimen 
and  the  original  description  quoted  above.  The  National  Museum 
specimen  has:  Dorsal  rays  XI,  11;  anal  IV,  7;  pectoral  13;  scales  in 
lateral  line  42.  All  of  these  counts  fit  coruscus.  There  is  a  spot 
distally  on  the  membranes  between  the  first  and  fourth  dorsal 
spines.  Since  the  snout  was  broken  the  measurements  of  the  head 
and  body  which  were  made  are  considered  not  reliable  and  are  not 
given.  At  the  time  this  type  was  examined  (1947)  no  attention 
was  paid  to  the  presence  or  absence  of  spinules  on  the  snout  present 
in  coruscus. 

Since  there  are  such  differences  in  the  counts  given  by  Poey 
and  the  specimen  labeled  type  in  the  National  Museum  it  appears 
possible  that  there  is  an  error  in  labeling  and  that  USNM  37428  is 
not  Poey's  type  of  productum.  At  any  rate  it  is  believed  USNM 
37428  is  certainly  a  specimen  of  coruscus. 

Studies  by  Nelson  show  that  the  structure  of  the  swim  bladder 
and  its  relation  to  the  auditory  bullae  as  well  as  the  structure  of 
the  bullae  themselves  are  similar  in  ascensionis,  rufus,  and  nominal 
meeki  (=  rufus).  The  form  and  relation  of  these  two  structures  are 
different  from  all  the  other  species  of  Holocentrus  that  were  exam- 
ined by  Nelson  (23  species,  but  not  including  the  nominal  osculus 
and  sanctipauli).

spine,  cheeks  rosy;  back  reddish  orange,  lower  sides  yellow.  In 
formalin-preserved  specimens:  three  distinct  brown  lines  along  back

Remarks. — This  species  has  been  recognized  by  Jordan  and 
Evermann  (1896,  p.  849)  as  a  subspecies  of  ascensionis  and  by 
Jordan,  Evermann,  and  Clark  (1930,  p.  236)  as  a  separate  species 
with  the  note,  "The  northern  form  probably  varying  into  H .  ascen- 
sionis, which  ranges  from  the  Bahamas  to  Brazil."  Specimens  in 
the  Chicago  Natural  History  Museum  collection  labeled  ascensionis 
from  Bermuda,  Bahamas,  Puerto  Rico,  St.  Croix,  Florida,  Mis- 
terioso  Bank  (Lat.  18°  30'  N.;  Long.  83°  30'  W.),  Glover  Reef, 
Panama,  Colombia,  Venezuela,  and  Brazil  (149  specimens  in  all) 
can  readily  be  separated  into  two  groups  based  on  the  number  of 
tube-bearing  scales  in  the  lateral  line.  Geographically  it  is  apparent 
that  ascensionis  is  commonly  found  from  Bermuda  throughout  the 
West  Indies  to  Santos,  Brazil,  while  rufus  appears  to  be  rare  in 
Central  America  and  northern  South  America  and  does  not  occur 
in  Brazil.  Only  one  rufus  was  found  among  17  specimens  of  ascen- 
sionis from  Panama.  In  the  West  Indies  and  Florida  the  two  species 
appear  to  be  equally  abundant.  In  Bermuda  ascensionis  has  been 
found  on  the  offshore  banks  and  in  the  passes  exclusively;  both  are 
found  together  along  shore  near  the  edge  of  the  reef,  while  rufus 
alone  was  collected  on  the  lagoon  reefs.    A  lot  of  21  specimens  from 


WOODS:  SPECIES  OF  HOLOCENTRUS  107 

Bermuda  (CNHM  no.  42867)  was  separated  into  two  groups  with 
the  following  differences  noted: 

rufus  ascensionis 

8  specimens  13  specimens 

Standard  length 87.70-168  81.40-191 

Head 3.14-     3.32  2.80-     3.17 

Depth  of  body 3.08-    3.35  2.80-    3.09 

Length  of  maxillary 8.08-     8.67  6.62-     7.15 

Preopercular  spine 13.40-  14.50  16.00-  18.70 

All  of  the  above  specimens  were  well  preserved  and  carefully  mea- 
sured. Specimens  of  each  sex  in  each  group  were  measured  and 
compared  with  the  above. 

Specimens  smaller  than  80  mm.  that  were  separated  on  the  basis 
of  lateral  line  scales  could  be  distinguished  by  all  characters  except 
size  of  eye  and  length  of  preopercular  spine.  In  measuring  additional 
specimens  from  other  parts  of  the  range  the  proportions  occasionally 
overlapped  but  individuals  aberrant  in  one  or  another  of  the  sepa- 
rating characters  could  always  be  distinguished.  In  all  cases  the 
lengths  of  the  upper  and  lower  jaws  were  different  and  after  the 
two  groups  had  been  distinguished  nearly  all  individuals  could  be 
sorted  by  inspection  before  scales  were  counted  or  measurements 
made. 

I  have  examined  Catesby's  figure  of  Perca  marina  rubra  (1731, 
2,  pi.  3,  fig.  2)  on  which  Walbaum  based  his  Perca  rufa.  This 
figure  is  not  carefully  drawn  and  was  made  from  a  specimen  with 
its  mouth  open  and  the  jaws  protruded  forward,  the  head  raised, 
and  the  opercular  bones  separated;  the  preopercular  spine  is  not 
clearly  delineated,  and  the  number  of  scales  and  fin  rays  is  not 
accurate.  Nevertheless,  Catesby's  figure  unmistakably  represents 
the  same  kind  of  fish  herein  called  rufus.  The  text  accompanying 
the  plate  mentions  color  but  otherwise  states  no  characters  of  any 
use  in  defining  the  species. 

A  specimen  from  St.  Thomas,  described  by  Regan  (1904,  p. 
259)  with  the  remark,  "I  have  no  doubt  it  is  the  little  known  H. 
osculum  of  Poey,"  has  been  received  on  exchange  from  the  British 
Museum.  This  specimen  agrees  in  all  respects  with  the  counts, 
measurements,  and  coloration  given  here  for  rufus.  The  lateral-line 
scales  number  52,  the  maxillary  extends  to  below  the  center  of  the 
pupil,  and  the  spiny  dorsal  membranes  bear  white  spots  distally. 

Mrs.  M.  M.  Dick  has  examined  the  type  of  H.  perlatum  Poey, 
MCZ  no.  10938,  said  by  Howell-Rivero  (1938,  p.  183)  to  be  a  syno-

WOODS:  SPECIES  OF  HOLOCENTRUS  109 

nym  of  H.  osculus  Poey.  The  measurements,  especially  of  the  eye 
and  the  maxillary,  and  the  length  of  the  latter  in  relation  to  the 
pupil,  as  well  as  the  color  of  the  dorsal  membrane,  all  support  my 
opinion  that  perlatum  is  a  synonym  of  rufus. 

Observations  by  Beebe  (1936,  p.  198)  on  specimens  of  H.  meeki, 
kept  alive  in  aquaria  on  Nonsuch  Island,  Bermuda,  are  summarized 
as  follows:  "Little  by  little,  in  the  course  of  several  weeks  they 
changed  from  Holocentrus  meeki  to  the  common  squirrel  fish,  Holo- 
centrus  ascensionis.  .  .  .  There  was  no  doubt  about  the  fact  that 
meeki  is  the  immature  stage  of  ascensionis."  I  have  again  counted 
the  lateral-line  scales  on  the  types  of  H.  meeki  and  find  52  and  53 
bearing  tubes.  Other  specimens  collected  by  Mowbray  in  Bermuda 
(CNHM  no.  49077),  certainly  the  same  as  the  types  of  meeki,  have 
51  and  56  tubed  scales.  This  number  agrees  with  rufus  rather 
than  with  ascensionis.  Also,  the  number  of  fin  rays  and  gill  rakers 
of  meeki  are  within  the  range  of  rufus.  There  are  three  specimens 
from  Bermuda  (CNHM  no.  48723),  70.5  to  71.7  mm.  standard 
length,  that  have  completely  transformed  and  resemble  young  rufus 
in  shape  of  head  and  size  of  eye.  The  preopercular  spine  is  short, 
however,  proportionately  equal  to  ascensionis  of  the  same  size.  The 
depth,  head,  size  of  eye,  and  length  of  maxillary  are  different  from 
those  of  ascensionis. 

Types  of  meeki  are  69  and  75  mm.  standard  length.  Three 
specimens  from  Brazil  that  measure  58,  65,  67  mm.  and  one  from 
Puerto  Rico  that  is  52  mm.  are  completely  transformed  and  resemble 
young  adults  in  shape  of  head  and  size  of  eye.  The  mouth,  however, 
is  small  (7.2,  7.31,  7.24)  but  still  larger  than  the  mouth  size  of 
rufus  (71.2,  70.7,  and  70.0  mm.  standard  length;  length  of  upper 
jaw  9.25,  8.64,  8.76  in  standard  length  repectively) .  (The  specimen 
of  ascensionis  from  St.  Croix  that  resembles  meeki  in  its  stage  of 
development  is  61  mm.)  I  am  of  the  opinion  that  ascensionis  trans- 
forms at  a  smaller  size  than  rufus.

110  FIELDIANA:  ZOOLOGY,  VOLUME  37 

Six  specimens  measured,  53.7  to  142  mm.,  from  Bermuda, 
Glover  Reef,  and  Panama. 

Description. — Dorsal  fin  rays  XI,  13  (rarely  14) ;  anal  rays  IV,  9 
(rarely  8  or  10) ;  pectoral  rays  ii,  13  (rarely  ii,  12  or  ii,  14) ;  scales  in 
lateral  line  bearing  tubes  40-44,  33^  rows  between  lateral  line  and 
origin  of  dorsal,  8  between  lateral  line  and  anal  opening;  gill  rakers 
on  first  gill  arch  6  or  7  on  upper  limb,  one  at  angle,  11  (rarely  10) 
on  lower  limb,  total  17-19. 

Depth  of  body  2.54-2.79,  length  of  head  2.56-3.03,  length  of 
snout  12.5-13.4,  diameter  of  eye  6.17-9.05,  width  of  interorbital 
9.37-10.8,  length  of  upper  jaw  7.56-8.82,  length  of  lower  jaw  5.65- 
6.90,  length  of  preopercular  spine  10.5-18.0,  depth  of  caudal  peduncle 
9.84-11.2,  length  of  caudal  peduncle  4.93-6.55,  length  of  fourth 
dorsal  spine  5.37-6.17,  length  of  third  anal  spine  4.18-5.08,  length 
of  pectoral  fin  3.86-4.51,  length  of  pelvic  fin  3.97-4.68,  length  of 
upper  caudal  lobe  3.55-3.91,  length  of  lower  caudal  lobe  3.99-4.18, 
all  in  standard  length. 

Body  deep,  compressed,  upper  profile  angular;  mouth  small, 
premaxillary  extending  posteriorly  to  below  a  point  midway  between 
anterior  margin  and  center  of  pupil;  lower  jaw  fitting  into  upper, 
not  entering  profile;  no  spinules  on  snout;  dorso-anterior  margin  of 
orbit  broadened  into  flange  bearing  heavy  obtuse  spines  in  specimens 
of  80  mm.  and  greater  (a  specimen  54  mm.  had  orbit  flanged  but 
spines  did  not  reach  margin,  which  was  entire);  opercular  spines 
two,  these  nearly  equal  in  size  (usually  lower  is  longer  and  sometimes 
stronger) ;  preopercular  spine  rugose,  extending  beyond  lower  margin 
of  subopercle;  third  anal  spine  equal  to  or  slightly  shorter  than 
anterior  anal  soft  rays,  when  pressed  parallel  with  lengthwise  axis 
of  body  its  tip  not  reaching  end  of  body. 

Color. — In  alcohol:  three  broad  dark  brown  lengthwise  lines 
above  lateral  line,  running  between  scale  rows,  centers  of  scales 
pale;  head,  breast  and  lower  sides  with  brown  puncticulations;  sides 
below  lateral  line  with  faint  broad  brown  lines  narrowing  and  fading 
posteriorly  (not  evident  in  largest  specimens);  axil  of  pectoral  jet 
black  in  young,  dusky  in  large  individuals;  spiny  dorsal  membranes 
dusky  distally  with  vertical  brown  or  black  line  covering  most  of 
membrane  immediately  anterior  to  each  spine;  membrane  between 
third  and  fourth  anal  spines  sometimes  faintly  dusky  distally;  rest 
of  fins  pale. 

Remarks. — The  specimen  figured  by  Fowler  (1904,  p.  234,  fig. 
5),  stated  to  be  the  type  of  H.  sicciferum  Cope,  is  certainly  a  small 


WOODS:  SPECIES  OF  HOLOCENTRUS  111 

specimen  of  H.  vexillarius.  The  counts  of  dorsal,  anal,  and  pectoral 
fin  rays  given  by  both  Cope  and  Fowler  are  within  the  range  of  this 
species  (see  table)  and  this  combination  of  counts  does  not  fit  any 
other  Atlantic  species.  H.  sicciferum  is  reported  by  Cope  to  have  45 
lateral-line  scales.  Three  of  our  specimens  have  44  tubed  scales 
and  the  one  following  the  last  tubed  scale  is  not  much  smaller  and 
is  perforated  so  the  apparent  difference  of  sicciferum  is  attributed  to 
method  of  counting.  In  our  series  of  specimens  from  Bermuda 
ranging  in  size  from  38  to  142  mm.  there  are  some  whose  dorsal 
fins  are  colored  as  shown  in  Fowler's  figure  of  the  type  of  sicciferum. 
The  large  eye,  small  mouth  and  abruptly  down-curved  snout  as 
well  as  the  relatively  deep  body  are  all  characteristic  of  this  species 
at  all  sizes. 

The  figure  and  description  in  Metzelaar  (1919,  p.  43)  of  H. 
coruscus  are  based  on  small  vexillarius.  His  counts — dorsal  XI, 
133^-14;  anal  IV,  9 — and  his  figure  showing  the  black  pectoral  axil 
could  refer  to  no  other  species  than  vexillarius. 

One  large  specimen  from  Bermuda  (142  mm.,  approx.  175  total 
length)  agrees  with  the  details  of  proportions  and  color  pattern 
given  by  Poey  for  brachypterus,  the  type  specimen  of  which  he  stated 
to  be  195  mm.  in  length.  The  only  discrepancy  is  in  the  number  of 
soft  anal  rays,  stated  to  be  8  by  Poey.  I  have  found  9  soft  rays  in 
most  specimens  of  vexillarius  counted,  but  one  had  8  and  another 
10  rays. 

H.  riparum  was  based  on  a  specimen  of  50  mm.  If  this  is  total 
length  (including  caudal  fin)  it  is  almost  certainly  a  larval  stage. 
The  counts  of  riparum  agree  with  vexillarius  as  do  the  markings  on 
the  dorsal  fin  membranes  described  by  Poey.  Howell-Rivero  (1938, 
p.  183)  examined  the  type  specimens  of  riparum  and  listed  them  as 
synonyms  of  vexillarius. 

Holocentrus  hastatus  Valenciennes,  ranging  from  Cape  Verde  Is- 
lands to  Angola,  according  to  Fowler  (1936,  pp.  549-551)  appears 
to  be  a  close  relative  of  H.  vexillarius.  It  differs  in  having  dorsal 
rays  XI,  15,  anal  IV,  10,  scales  48  to  51,  and  in  having  the  dark 
color  on  spiny  dorsal  membranes  limited  to  the  anterior  portion  of 
the  dorsal.  No  specimens  of  this  species  were  examined  by  me; 
the  above  notes  are  from  Fowler  (loc.  cit.)  who  also  regarded  hastatus 
as  a  close  relative  of  sicciferum  Cope,  here  considered  a  synonym 
of  vexillarius.

Body  elongate,  slender,  but  sides  more  rounded  than  other 
Atlantic  species  of  Holocentrus;  mouth  large,  upper  jaw  reaching 
posteriorly  to  below  center  of  pupil;  lower  jaw  very  slightly  shorter 
than  upper,  not  fitting  inside  upper;  a  patch  of  spinules  on  snout 
between  nares  and  premaxillary  groove  (fig.  14),  one  or  two  spines 
extending  laterally  over  posterior  narial  opening;  antero-dorsal  mar- 
gin of  orbit  entire;  opercular  spines  two,  the  upper  longer  and 
stronger;  preopercular  margin  serrate,  a  strong,  keeled  spine  at  its 
angle  extending  beyond  spines  of  ventral  portion  of  subopercle; 
third  anal  spine  longer  than  anterior  anal  rays,  when  laid  back 
falling  short  of  end  of  body;  caudal  forked,  lobes  rounded. 

Color-In  alcohol:  reddish  brown  with  three  narrow,  white, 
lengthwise  lines  following  centers  of  scale  rows  above  lateral  line, 
lines  broader  below  lateral  line;  cheek  white  with  oblique  brown 
band  from  orbit  to  postero- ventral  angle,  breast  silvery;  spiny 
dorsal  fin  with  prominent  black  oval  spot  distally  on  membranes 
between  first  three  spines  in  large  specimens,  sometimes  extending 


WOODS:  SPECIES  OF  HOLOCENTRUS  113 

to  fourth  spine,  rest  of  dorsal  membranes  faintly  dusky  distally; 
soft  dorsal  and  other  fins  pale;  pectoral  axil  pale. 

Remarks. — Although  Parr  (1930,  p.  36)  has  stated  that  Poey's 
original  description  of  this  species  is  inadequate  for  proper  identi- 
fication, I  believe  Poey's  combination  of  counts  (dorsal  XI,  12; 
anal  IV,  8;  pectoral  13)  must  refer  either  to  coruscus  or,  possibly,  to 
bullisi,  which  has  no  large  black  spot  on  the  dorsal.  From  the 
counts  given  by  Jordan  and  Bollman  (1889,  p.  550)  and  Beebe  and 
Tee  Van  (1928,  p.  81,  fig.)  it  appears  that  all  these  authors  had 
specimens  of  H.  vexillarius  with  13  dorsal  rays  and  9  anal  rays. 
Two  of  Beebe  and  Tee  Van's  counts  give  8  and  8%  anal  rays. 
H.  tortugae  Jordan  and  Thompson  and  H.  puncticulatus  Barbour 
are  also  certainly  the  same  species.  I  have  compared  numerous 
Bermuda  and  Bahama  specimens  with  the  original  descriptions  of 
these  two  species  and  can  find  no  significant  differences.  Both 
descriptions  state  13  dorsal  rays  and  both  figures  show  12.  Both 
figures  also  show  the  characteristic  spinules  on  the  snout,  but  these 
are  not  mentioned  in  the  descriptions.  Longley  and  Hildebrand 
(1941,  pp.  54-55)  have  discussed  these  spinules  and  other  contrasting 
differences  between  coruscus  and  vexillarius.

margins,  preopercular  spine  strong  with  keel  basally,  reaching  just 
beyond  longest  spine  of  subopercle  in  type,  longer  in  paratypes; 
dorsal  fin  almost  completely  divided,  third  and  fourth  dorsal  spines 
subequal  and  slightly  shorter  than  soft  rays;  third  anal  spine  longer 
than  anterior  anal  rays,  when  pressed  down  reaching  to  base  of 
caudal  rays;  caudal  forked,  rays  broken  on  type  so  exact  shape  of

appearance  of  very  narrow  brown  border  to  white  line,  very  faint 
in  largest  paratype;  below  lateral  line  four  broader  white  lengthwise 
lines,  narrowing  and  fading  posteriorly,  brown  border  of  these  lines 
scarcely  evident  on  type;  fins  all  pale  except  for  a  minute  dusky 
spot  distally  immediately  behind  first  dorsal  spine  on  type,  on 
smallest  paratype  traces  of  dusky  vertical  streaks  on  each  membrane; 
pectoral  axil  pale. 

Remarks. — This  species  appears  to  be  most  closely  related  to 
Holocentrus  coruscus  Poey,  from  which  it  differs  as  follows: 

bullisi  coruscus 

Pectoral  rays 14  12  or  13 

Lateral  line  scales 40  and  41  42  to  45 

Narial  spine Absent  Present 

Color  of  dorsal See  above  Oval  black  spot 

distally  between 
first  3  spines 

From  ascensionis,  rufus,  and  vexillarius,  bullisi  differs  in  number 
of  fin  rays,  scales,  and  color;  from  marianus  it  differs  in  number  of 
lateral  line  scales,  structure  of  dorsal  (XI  in  bullisi,  X,  I  in  marianus) 
(see  table  for  counts).
