Frontispiece. Chionelasmus darwini (Pilsbry)*, one of the most generalized or primitive living balanomorphans, is known from 
two isolated insular situations where it inhabits relatively deep water (approx. 450m|. The first specimens were taken near the 
turn of the century by the U. S. Fisheries Steamer Albatross off Kauai Island, Hawaii, and then a couple of decades later by a 
cable ship off Rodriguez Island, southwestern Indian Ocean. While additional specimens have been taken near the original 
locaUties, there are no reports of any having been found between these two extremes. Chionelasmus therefore qualifies as a 
refugial form, but not a usual one since it is both insular and in relatively deep water, well out of the mainstream of balanomorph

The Cirripedia constitutes a diverse and 
abundant subclass of crustaceans, and repre- 
sentatives are found in virtually all marine 
environments. There are four orders, the Asco- 
thoracica, Rhizocephala, Acrothoracica and 
Thoracica. The Thoracica contains the true 
barnacles and these are distributed between 
three living suborders; the stalked barnacles or 
Lepadomorpha, the asymmetrical sessile bar- 
nacles or Verrucomorpha, and the sessile acorn 
barnacles or Balanomorpha. These appear in the 
Silurian, the middle Cretaceous, and the late 
Cretaceous, respectively. The Balanomorpha en- 
compasses the greatest diversity of free-living 
and symbiotic forms, and as Darwin (1851a:5) 
noted, the present epoch may go down in the 
fossil record as the "Age of Barnacles" (Fig. 17). 

The basic classification of the Thoracica 
was formulated by Darwin (1854b), and his 
system was expanded and somewhat revised by 
Pilsbry (1907a;1916). Pilsbry's classification 
formed the basis for that in the Treatise on 
Invertebrate Paleontology (Newman et al, 1969). 
Although the Treatise provides diagnoses of taxa 
to the generic level, it does not enumerate 
the species contained in each genus, nor does it 
provide a guide to the hterature concerning 
them. The present study fills these needs for the 
Balanomorpha. It also constitutes the first major 
revision of higher taxa in more than half a century. 

The Balanomorpha may not be an entirely 
natural assemblage, but rather a grouping of 
phylogenetically parallel lineages not readily 
derivable from one another nor from a common 
balanomorph ancestor. The possibility of at least 
a diphyletic origin was suggested by Withers 
(1924:2). Thus, in preparing this revision we 
were alert to the possibility that the Balano- 
morpha might be separable into two or three 
suborders. However, in the final analysis it be- 
came clear that such a proposal was indefens- 
ible or premature. Therefore, the Balanomorpha 
in the broad sense has been retained. Yet three 
major lineages can be recognized, and we con- 
sider them to constitute superfamilies: Chthama- 
loidea, Balanomorphoidea and Balanoidea. In 
addition, one new family and numerous sub- 
families are also proposed here, and many of 
the 65 genera contained in the Balanomorpha 
are redistributed within this modified systematic 
framework (Fig. 1). 

Much of what has been done here might be 
interpreted by the casual observer as simply 
"splitting" and "rank-raising." Indeed, Hyman 

(1959:697) voiced concern over systematic prac- 
tices in recent years: "Any acute observer can- 
not fail to notice the disease prevalent in 
zoological systematics today of raising rank of 
groups and of assigning high ranks to groups 
that differ only in minor characters." Neverthe- 
less, in the present study new lines of evidence 
indicate previously unrecognized affinities, and it 
seems to us that the classification must be altered 
and expanded to accommodate them. 

Initially, classification of thoracicans de- 
pended on surficial morphology of the shell, 
and it is only in recent years that thin sec- 
tions have revealed remarkable internal struc- 
tures that have drastically altered our under- 
standing of the affinities among the 
Balanomorpha. Likewise, comparative studies of 
trophi and chaetotaxis, or of such structures as 
the base of the intromittant organ, have greatly 
improved and broadened our understanding of 
interrelationships between higher and lower 
taxa. In addition, numerous collections by both 
individuals and expeditions, from the deep sea, 
from coastal waters, and especially from tropical 
seas where the greatest diversity is found, have 
provided new materials that have compelled us 
to alter our concepts and rearrange existing 
groupings in order to continue to develop a 
natural system. If our system is accepted, the 
practical inconvenience and annoyance will really 
be quite temporary. 


The specialist will probably have httle dif- 
ficulty in using this work, but some explana- 
tions seem appropriate. It is divided into three 
parts: evolution, systematics and catalog of 
species. We have attempted to arrange the 
genera and higher taxa phylogenetically. How- 
ever, for simplicity, ease, and (or) lack of 
knowledge, species are listed alphabetically under 
their respective genera or species groups in the 
catalog. The index is the entree to species. 
The first page number given after each species 
leads to that species in the catalog. For genera 
and higher categories, and for some species, the 
index leads into the systematic and evolutionary 
sections as well. Species names in the index are 
given without generic indication unless they 
have been used in more than one genus. In 
such cases the generic names used in this work 
are given. 


Diagnoses of suprageneric taxa, and for a 
single new genus (Notobalanus), are provided 
in the systematic section. Diagnoses for estab- 
lished genera can be found in the Treatise on 
Invertebrate Paleontology (1969); original sources 
for subsequently described genera are cited 

The general arrangement of the catalog fol- 
lows that of the preceding evolutionary and 
systematic sections. The original author, date 
and page are cited for each species and, where 
appropriate, a citation of the most compre- 
hensive synonomy, which may not necessarily 
be the most recent. This is followed by a 
relatively complete list of references through 
1973, but including many through 1975; many 
of the non-systematic papers are briefly anno- 
tated. Finally, general distributional and some- 
times bathymetric and stratigraphic data are 
included, but needless to say, distribution of the 
majority of the species is very poorly known. 
Following the body of the catalog there is a list 
of species incertae sedis. 


The primary data base for this work was, 
quite naturally, the hterature, and we have 
cited virtually all that was available to us. 
Much of the contemporary literature was made 
available as reprints by authors and others, 
and we thank them for their generosity. A 
large portion, however, came from various 
university and museum libraries, over many 
years, through direct borrowing and interhbrary 
loans. Librarians involved are too numerous to 
mention individually, but we thank them, known 
and unknown to us, for their services. 

As with many data bases, sources extend 
well beyond pubhshed works, and we are much 
indebted to numerous cirripedologists for vol- 
uminous oral and written communications. There 
have been so many we hesitate to mention 
them by name, for fear of not including all. 
But we must acknowledge Huzio Utinomi of the 
Seto Marine Biological Laboratory; Alan J. 
Southward of The Laboratory, Plymouth; EUza- 
beth C. Pope of the Australian Museum; and 
Victor A. ZuUo, University of North Carolina 
at Wilmington. 

Data were also extracted from the vast 
collections of the Scripps Institution of Oceanog- 
raphy and the San Diego Natural History 
Museum, and from materials made available on 
loan by curators of collections in other insti- 
tutions. In particular, we would Uke to thank 
Thomas E. Bowman of the National Museum 

of Natural History; Torben Wolff of the Zoologi- 
cal Museum, Copenhagen; Jan Stock of the 
Zoological Museum, Amsterdam; L. B. Holthuis 
of the Rijkmuseum, Leiden; J. P. Harding of 
the British Museum (Natural History); WiUiam 
K. Emerson of the American Museum of Natural 
History; and J. Wyatt Durham of the Paleon- 
tology Department, University of California, 
Berkeley. We have also garnered knowledge and 
experience from innumerable specimens sent to 
our laboratories for identification by ecologists 
from all over the world. 

Development of the catalog has passed 
through the hands of several assistants. It be- 
gan many years ago as a compilation of 
references to species of immediate interest in 
contemporary literature, and was subsequently 
expanded to include all primary hterature on 
all species by Mrs. Carol Platt-Kourtz, who 
carried it forward for five years as a sideline 
to her regular work. Mrs. Cecelia Ross spent 
nearly a year of intensive work on it, and 
finally Ms. Gayle Kidder aided substantially in 
bringing it to its present state. We thank 
these young ladies for their concerted efforts 
and ask their forgiveness for the moments 
when attention to detail became excessively 

This revision is for the most part a by- 
product of our work on the systematics of the 
Cirripedia. Support, in part, was provided by 
several grants from the National Science Foun- 
dation (to W.A.N. : GB-4973X through BMS575- 
17149), and these are gratefully acknowledged. 


Classification of the thoracican Cirripedia, 
beginning in good part with the work of Leach 
(1817, 1818, 1825) and Gray (1825), was placed 
on a firm foundation by Darwin (1851-1854). 
Darwin's three basic divisions, the Lepadidae, 
Verrucidae and Balanidae, are the principal 
ones recognized today (Pilsbry, 1907a, 1916; 
Kriiger, 1940; Withers, 1953; Newman et al, 
1969). Progress in the classification of the 
Thoracica, from Leach (1817-1825) to that being 
proposed, is given in Figure 1. Gruvel's (1903b) 
classification is omitted. Suprageneric taxa are 
indicated only under the Balanomorpha. 

The Lepadomorpha (= Lepadidae sensu 
Darwin) contains the most primitive Thoracica, 
members of which are inferred to have arisen 
from a free-hving stem near the Ascothoracica 
(see Newman et al, 1969; Newman, 1974:437). 
While the unity of the Lepadomorpha has never 
been questioned, the relationships of the scalpeUi-

form and lepadiform groups remain obscure. 
However, problems that arise in this regard 
have no direct bearing when considering the 
origins of the Balanomorpha, because it is 
generally agreed that one looks to the scalpelli- 
form or pollicipoid barnacles for the antecedents 
of the sessile barnacles (Darwin, 1854b; Withers, 
1953; Broch, 1924; Newman et al, 1969; Newman 
and Ross, 1971). 

Darwin's (1854b) classification of the 
Thoracica reflects the view that the sessile 
barnacles (Verrucidae and Balanidae) evolved 
from the Lepadomorpha as independent lineages. 
The Verrucomorpha was recognized by Darwin 
(1854b:495) as sharing a number of character- 
istics with the Lepadomorpha and the Chtha- 
mahdae among the Balanomorpha. However, the 
sum of the characters he enumerated favor a 
lepadomorph rather than a balanomorph an- 
cestry for them. Withers (1914:945) considered 
Prouerruca from the upper Cretaceous to "con- 
stitute, in fact, the 'missing link' between the 
pedunculate Cirripedes of the family Polhcipedi- 
dae [= Scalpellidae] and the sessile asymmetri- 
cal Cirripedes of the family Verrucidae." The 
two lateral plates of one side seen in Prouerruca, 
and Eouerruca but missing in Verruca, are 
homologous with those of the presumed an- 
cestor of the Balanomorpha as well as the 
Verrucomorpha. Thus, what these early verrucids 
indicate is that the lepadomorph ancestors of 
both suborders were comparable (Fig. 2). 

The next sessile suborder, the extinct 
Brachylepadomorpha, was unknown to Darwin. 
It was instituted by Withers (1923:37) to ac- 

commodate Brachylepas, which Woodward (1901: 
150) previously considered a pedunculate bar- 
nacle. Withers (1953) subsequently discovered 
that Pycnolepas Withers (1914) was not only 
a sessile barnacle, but also that it was inter- 
mediate in structure between stalked barnacles 
and Brachylepas (Fig. 2). He stated that, 
while the Brachylepadomorpha "includes the 
commonest and most widespread of the Cre- 
taceous symmetrical sessile cirripedes. . . ." 
they "do not appear to be in the direct line 
of descent of the Balanomorpha, as already 
pointed out by Pilsbry. They apparently repre- 
sent an independently developed sessile type, 
which, except for the reduced number of capitu- 
lar valves, probably resembled the ancestor of 
the Recent primitive Balanomorpha (Catophrag- 
mus)" (Withers, 1953:344; see Fig. 2). 

Gruvel's (1903b) classification of the Balano- 
morpha departed radically from Darwin's scheme, 
but it was rejected by Pilsbry (1907a, 1916) 
and subsequent workers as in good part un- 
natural. Pilsbry (1907a, 1916) elevated Darwin's 
famihes to suborders, primarily to allow for an 
expanded classification at subfamihal levels. 
Darwin's Balanidae thus became the Balano- 
morpha, containing two families, the Chthamah- 
dae and Balanidae. He further divided the 
Balanidae into the Balaninae, Chelonibiinae, and 
Coronuhnae, all primarily on the basis of shell 

Numerous subgenera, in good part based 
on characters Darwin (1854b) used in formu- 
lating sections, have been proposed, particularly 
by Pilsbry (1916) and Hoek (1907), especially

(see text for discussion.) 


in the Balaninae. Yet, in the years since Pilsbry 
(1916), few alterations have been made in the 
basic classification of the Balanomorpha. Nilsson- 
Cantell (1921) resurrected GruveFs (1903b) Tetra- 
clitinae (in part) as a subfamily of the Balani- 
dae, and fostered the Stellatus- and HembeU- 
groups of Chthamalus, suggested by Pilsbry 
(1916). Ross (1968) subsequently elevated the 
Tetraclitinae to familial level; Utinomi (1968) 
divided the Chthamalidae into three subfamilies; 
Ross (in Ross and Newman, 1967) created the 
subfamily Emersoniinae for an extinct form allied 
to the turtle barnacles; Newman and Ross (1971) 
proposed the family Bathylasmatidae for a group 
of relatively primitive deep water balanoids; 
and Ross and Newman (1973) resurrected Gray's 
(1825) Pyrgomatidae (in part), a name available 
for a group of coral barnacles designated 
Creusiinae by Baluk and Radwanski (1967b: 
468). Despite these advances the broad aspects 
of the classification have remained the same. As 
it stands, it fails to portray many actual or 
inferential relationships and this has necessitated 
the present revision. 

Although appUcation of the biological species 
concept spread in systematic studies of other 
groups, the Darwinian tradition of numerous 
varieties (subspecies) in the cirripeds has con- 
tinued to prevail, especially in the Stellatus- 
group of Chthamalus, Tetraclita s.s., the Balanus 
amphitrite group, the subgenus Megabalanus, 
and the coral barnacles. 

Students of the balanomorphs will find some 
unfamiliar features in what we propose and 
these may be quite disconcerting without back- 
ground information. Darwin's work on the Cirri- 
pedia had a profound two-fold effect. On one 
hand, he established the basic classification and 
brought order to a chaotic and wide spread 
literature. On the other hand, he arranged the 
higher taxa in such a manner as to bias 
virtually all subsequent phylogenetic studies. 
While Hoek (1913) and Pilsbry (1916) expanded 

upon the basic framework, they retained the 
Darwinian order in their monographs in which 
the morphologically primitive forms, the chtha- 
malids and coronuhnids, appeared at the end 
and the more highly evolved forms such as 
Megabalanus, appeared at the beginning. The 
first break in tradition came with Gruvel 
(1905a), and in a more acceptable manner, with 
the work of Nilsson-Cantell (1921), Kriiger (1940), 
and Withers (1953), where the various groups 
were, with the exception of the turtle and whale 
barnacles, placed in a more or less acceptable 
phylogenetic sequence. 

The present study is a further attempt to 
order the balanomorphs as naturally as possible, 
down to and including the subgeneric level. In 
doing so, some marked departures from pre- 
vious classifications have been made. This may 
not prove upsetting to new students of the 
Balanomorpha, but the "old Hne" may find it 
difficult to accept the turtle and whale barnacles 
as groups having relatively primitive origins, 
and to find the tetraclitids closer to them than 
to the balanids. 

It may also prove disconcerting to find 
that most free-living acorn barnacles cannot be 
readily assigned to either Chthamalus, Balanus 
or Tetraclita. But it must hkewise have been 
upsetting to earUer students of the group when 
certain workers decided that most barnacles 
were not Lepas as Linneaus had established. 
The changes proposed herein reflect a sharpen- 
ing of resolving power over the past decade or 
so, a sharpening made possible through the 
efforts of many students of this remarkable 
and fascinating group of animals. 

Beginning on page 25 we illustrate various 
features and relationships of the shells and ap- 
pendages of the balanomorphs. These were orig- 
inally prepared to aid us in our understanding 
of the diversity of morphologies involved, and it 
is hoped that they will be useful to the reader. 




Until recently the Balanomorpha consisted 
of the Balanidae and Chthamalidae. Darwin 
(1854a:152, 176) and subsequent authors, con- 
sidered the Chthamahdae the more primitive 
and directly derivable from scalpelliform bar- 
nacles. The criteria for this judgment cover both 
homologies of hard parts and morphology of 
appendages, especially in the most primitive or 
generalized chthamalid, Catophragmus (Catomer- 
us). The fossil record supports this interpreta- 
tion, because Catophragmus appears in the late 
Cretaceous. Representatives of the Balanidae do 
not appear until the early Eocene. 

In the chthamalid Pachylasma, while the 
body and appendages are wholly chthamaloid, 
the shell wall and to some extend the opercu- 
lum are in certain respects balanoid in appear- 
ance. Darwin (1854b:475) stated that when he 
first examined the shell of Pachylasma he "did 
not doubt that it was . . . Balanus." But when 
he examined the animal's body, he found the 
characteristics preeminently chthamaloid, and 
concluded that (1854b:477) "Pachylasma would 
be the point of contact [of the Chthamalidae] 
with the Balaninae, . . . [for] when the shell 
alone ... is examined, it is hardly possible to 
separate this genus [Pachylasma] from Balanus. " 
Unfortunately, the fossil record does not lend 
support to this view because Pachylasma first 
appears in the Miocene, well after the appear- 
ance of Balanus. Nonetheless, the implication 
exists; the Balanidae may have come from the 
Chthamahdae via Pachylasma. 

Subsequent work on the origin of the Balani- 
dae seemed to make a chthamahd ancestry 
more plausible. Hoek (1883, 1913) described a 
number of deep-water species that appeared by 
shell characters to belong to Balanus, but the 
nature of the soft parts, particularly the structure 
of the labrum and the third cirrus, was atypical, 
and while he considered them balanids, he pro- 
posed the genus Hexelasma for them. Pilsbry 
(1916) reviewed the status of this genus and 
concluded that the species in Hexelasma be- 
longed instead to the Chthamalidae, close to 
Pachylasma, and this assignment was followed 
by Kruger (1940), Withers (1953), Zullo (1963a), 
and Utinomi (1968). Zullo (1963c:190) oversimpli- 
fied this picture with his sweeping statement 
that "the Balanidae . . . differ materially from 
the Pachylasma group [including Hexelasma] 
only in the structure of the labrum . . . and 

that they were derived from the Pachylasma 
group stock." Despite this oversimphfication it 
would seem at this point that there would be 
relatively little difficulty in deriving balanids 
from chthamahds, for the shell of Pachylasma 
and soft parts of Hexelasma would appear, 
superficially, to bridge the gap. 

Taking this simplistic view at face value, a 
model for a monophyletic diversification of the 
Balanomorpha would be as follows (Fig. 2). The 
Chthamalidae, containing the most primitive 
members of the suborder, gave rise to the re- 
mainder of the Balanomorpha. Fundamentally, 
chthamahd hard parts consist of deeply articu- 
lated opercular valves, a wall of eight solid 
plates (three pairs of laterals overlapping the 
unpaired carina and rostrum), and several whorls 
of small imbricate plates, comparable to the 
peduncular plates of certain scalpeUids, surround 
the region where the wall contacts the sub- 
stratum. The basis is membranous. A large 
bullate, lepadomorphan-Uke labrum surrounding 
the mouth parts has mandibular palps situated 
on its lateral margins. The scalpellid-Uke man- 
dible, composed of several incisor-hke teeth and a 
spinous rather than molariform inferior angle, 
is simple. The first and second cirri are modified 
to assist in the transfer of food captured by 
the posterior four pairs to the mouth parts; that 
is they have been modified to serve as maxiUi- 
peds. The cirri, armed with simple setae and lack- 
ing speciaUzed spines are hke those of the Le- 
padomorpha. The penis, originating between the 
last pair of cirri below the anus and flanked by 
a pair of multiarticulate caudal rami or appen- 
dages (the furca), lacks a basidorsal point. All 
these features are found in the most generaUzed 
members of the extant Chthamaloidea, Catophrag- 
mus sensu lato, fossil forms of which are the old- 
est balanomorphs known (late Cretaceous). 

Diversification of the chthamahds included 
the appearance of a number of Uneages in all 
of which the whorls of imbricate plates were 
lost, the number of wall plates was reduced from 
eight to six, and in some cases four, and the 
caudal appendages inevitably disappeared 
(Fig. 4). The reduction of wall plates from eight 
to six was accomphshed in two different ways — 
most commonly the carinolaterals drop out, 
thereby retaining the arrangement where the 
rostrum as well as the carina remain over- 
lapped; and less commonly, the rostrolaterals 
fuse with the rostrum forming a compound plate 
that overlaps the adjacent laterals. The latter 


arrangement is the same as that seen in higher 
non-chthamalid Balanomorpha and is presumed 
to herald them. The chthamalid bullate labrum, 
inherited from the Lepadomorpha, gave way to 
the thick but non-bullate condition, with concomi- 
tant changes in the nature of the mandibles 
to the more advanced balanid type. The third 
cirri became intermediate in structure between 
the second and fourth rather than more closely 
resembling the fourth, and the opercular valves 
became complexly but not deeply articulated; 
all features seen in Hexelasma and related genera 

Further advances included a flattened labrum 
that became cleft, aiding in the removal of food 
from the cirri. Concomitant with this, the third 
pair of cirri completed the transformation to 
maxiUipeds. Apparently at this point the sohd- 
waUed Balanidae and Tetraclitidae appeared and 
diverged from the ancestral Bathylasmatidae 
(Figs. 2, 4 and 5). Both went on to develop 
distinctly different complex wall tj^es, variously 
armed cirri, and in the balanids, a penis with 
a basidorsal point. 


As palatable as the monophyletic scheme 
may be, Zullo (1963c:190) noted that there were 
conflicting views regarding affinities within the 
Balanomorpha and that it is possible that the 
balanomorphs are polyphyletic. Withers (1924:2) 
stated that he was "not at all convinced that 
the Chthamalidae and Balanidae . . . are so 
nearly related as is supposed," but he did not 
pursue the subject in subsequent writings 
(through 1953). Recently, Utinomi (1968:33), 
expressed a similar view, suggesting that the two 
families were independently derived from lepado- 
morph ancestors, but unfortunately he did not 
elaborate further on the matter. We became 
involved in the problem of the unity of the 
Balanomorpha when working on a revision of 
Hexelasma (Newman and Ross, 1971). In this re- 
gard, Bage (1938:10) had already pointed out 
that, "from the examination of the soft parts 
of the animal it is apparent that the reference 
of the genus [Hexelasma] to the Balanidae or 

Sessile Cirripedia 
Pedunculate Cirripedia 

Figure 3. Polyphyletic origin of sessile cirripeds: It is weU documented that extinct Brachylepadomorpha and the Verruco- 
morpha (Jurassic to middle Miocene, and middle Cretaceous to Holocene, respectively) evolved from pedunculate ancestors be- 
fore the appearance of the Balanomorpha (Cretaceous to Holocene). The Balanomorpha also descended from pedunculates rather 
than from earlier sessile groups (see fig. 2 for fundamental structural differences). Thus, sessiUty evolved three times. However, 
there have been suggestions in the literature that two or more of the principal divisions of the Balanomorpha also may have had 
separate pedunculate ancestors, as illustrated here. If this were so, sessihty within the Thoracic would have evolved four or five 
times (see text for discussion). 


Chthamalidae, discussed by Hoek (1913) and 
Pilsbry (1916), remains unsettled." In our study 
(Newman and Ross, 1971:143) it became clear 
that Hexelasma and its allies stand distinctly 
apart from the chthamaloids and balanoids and 
that it was impossible to supply facts supporting 
the long standing view that it is from the 
chthamaloids, through Pachylasma and Hexe- 
lasma, that the balanoid barnacles have descend- 
ed. Therefore, we instituted the Bathylasmatidae, 
to accommodate several genera, including 
Hexelasma, because the group could not be 
properly assigned to either the Chthamalidae or 
the Balanidae, and suggested that antecedents of 
the bathylasmatids may well be found among the 
scalpellid Lepadomorpha rather than the 

However, in the aforegoing, the balanoid 
rather than chthamaloid affinities of the Bathy- 
lasmatidae were emphasized, and while the Tetra- 
clitidae was recognized as a distinct family, 
it was placed rather closer to the Balanidae 
than the Chthamalidae, with the "elminoids" 
standing in a somewhat intermediate and ques- 
tionable position (Newman and Ross, 1971:143). 
Ross (1970:9) provided the solution to the last 
problem by demonstrating that at least two 
species referred to Elminius by previous authors 
were in fact tetraclitids rather than balanids. 
Hence the difficulties posed by the elminoids 

evaporated and the four famiUes of the Balano- 
morpha became more sharply defined. 

The gulf between chthamaloids and balanoids 
is particularly great. The tetrachtids and bathy- 
lasmatids are envisaged here as more closely 
related to one another than to either the 
chthamaloids or the balanoids. Although the 
tetraclitids and bathylasmatids are separable, 
there is presently no reason to believe that the 
former have not evolved from the latter, and it 
is to this complex rather than the balanoids 
that we infer the coronulines and chelonibiines 
are most closely related. Thus, it remains pos- 
sible that the Balanomorpha is triphyletic; an 
artificial assemblage of three independently 
evolved sessile types (Fig. 3). If this were the 
case, sessility was achieved five times in the 
Thoracica: once in the Verrucomorpha, once in 
the Brachylepadomorpha, and three times in the 
Balanomorpha — all from comparable, but lepado- 
morph ancestors. Nonetheless, for the aforemen- 
tioned reasons, the Balanomorpha is retained 
here, even though it may not be a natural 
grouping. As a partial solution to this problem 
we propose that the families recognized here be 
distributed between three superfamiUes, the 
Chthamaloidea, the Balanomorphoidea, and the 
Balanoidea. Should polyphyly be documented in 
the future, one or more of these would of neces- 
sity become suborders. 




Darwin (1854b:486) commented that 
"... Catophragmus forms, in a very remark- 
able manner, the transitional link [between the 
Chthamalidae and the Lepadidae], for it is 
impossible not to be struck with the resemblance 
of its shell with the capitulum of Pollicipes. 
In Pollicipes, at least in certain species, the 
scuta and terga are articulated together — the 
carina, rostrum, and three pairs of latera, mak- 
ing altogether eight inner valves, are consider- 
ably larger than those in the outer whorls — 
the arrangement of the latter, their manner of 
growth and union, — all are as in Catophrag- 
mus. If we, in imagination, unite some of the 
characters found in the different species of 
Pollicipes, and then make the peduncle so short 
(and it sometimes is very short in P. mitella) 
that the valves of the capitulum should touch 
the surface of attachment, it would be impos- 
sible to point out a single external character 
by which the two genera . . . could be dis- 
tinguished." As Withers (1928b) noted, Pilsbry 
(1916) suggested an even nearer hkeness with 
the more speciaUzed Sciliaelepas, and this model 
was adopted by Newman et al (1969:R269, fig. 90). 

Darwin further noted that the trophi of 
chthamaloids are similar to those of lepado- 
morphs. The labrum is thick and bullate, and 
this is basically a lepadomorphan character. 
The tridentoid mandibles and the multiarticulate 
caudal appendages of the primitive chthamaloids 
are typical of the pollicipoid lepadomorphans, 
and it is the sum of these arthropodal struc- 
tures that separate the chthamaloids from other 
Balanomorpha. The first and second cirri are 
modified for cleaning the posterior net-forming 
pairs of particulate matter and transferring it 
to the mouth. In lepadomorphs, generally but 
one pair of cirri is so modified, but pollicipoids 
have modifications of the second and even the 
third pairs (Darwin, 1851b:313). Finally, the base 
of the penis is simple, without basidorsal point, 
as in all thoracicans except the Balanoidea. In 
general, the trophi and chaetotaxis are most con- 
servative throughout the lower chthamaloids and 
readily distinguish the entire stock from the re- 
mainder of the Balanomorpha. The facies simi- 
larity with pollicipoids is indeed most striking. 

Virtually nothing more could be asked for in 
a generalized ancestor for the higher Chthamaloi- 
dea than Catophragmus and Catomerus — all 
the essential parts are there. All that needs 

to be done is to modify the form, by loss or 
fusion of shell parts and loss or specialization 
of appendages and trophic structures, in or- 
der to produce the diversity of taxa presently 
observed within the superfamily (Fig. 4). 

Relationships between genera have been noted 
by various authors. Pilsbry (1916:291) took a 
somewhat Gruvellian approach, and arrayed 
them in phylogenetic order, primarily according 
to number of wall plates. He also divided the 
most species-rich genus, Chthamalus, into two 
groups based on the nature of the mandible. 
These were refined and named informally by 
Nilsson-Cantell (1921) as the quadridentoid 
Stellatus-group and the tridentoid Hembeh-group. 

Zullo (1963c) observed that the more gen- 
eralized tridentoid mandible of the Hembeli- 
group was the type common to more primitive 
chthamaloids and, coupled with differences in 
mode of shell reduction, proposed that the 
Chthamalidae be divided into three groups: 
the quadridentoid Chthamalus, Chamaesipho, 
and Octomeris, and tridentoid Catophragmus, 
Chionelasmus, and Euraphia, and the tridentoid 
Pachylasma. The Pachylasma-group included 
Hexelasma (Zullo, 1963a). This is essentially 
Pilsbry's (1916:291) classification. Pope (1965), 
in a most scholarly review, pointed out some 
problems with the tri- and quadridentoid aspects 
of the division and this will be returned to 

Although Utinomi (1968:36) avoided dealing 
with the problems that arise when using the 
mandibles as a key taxonomic character, he 
formally designated subfamilial divisions for 
what were essentially the Pilsbry-ZuUo group- 
ings: the Catophragminae (Catophragmus, Cato- 
merus, and Chionelasmus), the Chthamahnae 
(Chthamalus, Chamaesipho, and Octomeris), and 
the Pachylasminae (Pachylasma, Hexelasma, 
and Tessarelasma). To the Catophragminae one 
must add the late Cretaceous Pachydiadema 
Withers (1935); to the Chthamahnae, the Recent 
Tetrachthamalus Newman (1967) and Jehlius 
Ross (1971); and from the Pachylasminae, or 
rather from the Chthamaloidea in general, re- 
move Hexelasma and Tessarelasma (see Newman 
and Ross, 1971:142). We are otherwise in ac- 
cord with Utinomi 's groupings, but not as 
coordinate taxa (Fig. 4). 

The Catophragmidae comprises an ancient 
and generalized stock; there is a significant 
gap between it and the remaining subfamihes. 
The differences, aside from the supplementary 



Figure 4. Radiation of the Chthamaloidea: It seems unlikely that Chionelasmus and Pachytasma (the only deep-sea members of 
the superfamily) evolved from intertidal catophragmids {Catophragmus and Catomeris) whose trophi and anterior cirri are much 
more specialized. By default then, the extinct Pachydiadema becomes a more hkely candidate. It also seems unlikely, for the 
same reasons, that Octomeris gave rise to Pachytasma, or vice versa since the opercular valves of Pachylasma are already 
advanced. Finally, while it seems unlikely that Chionelasmus gave rise to six-plated euraphiines, the possibility cannot presently 
be ruled out. 

If higher balanomorphans arose from chthamaloids, workers since and including Darwin (1854b) consider that it would have 
been via a pachylasmine ancestor (see text for further discussion). 


whorls of plates in the Catophragmidae, are 
the extremely primitive nature of the primary 
wall plates and the opercular valves. Even in 
Chionelasmus. where the supplementary plates 
have been reduced to but a single whorl, 
and the primary wall plates from eight to six, 
the primitive pollicipoid facies is retained. 

The jump from Catophragmidae to Chtha- 
malidae is wholly in "modernization" of the 
wall, the arthropodal structures remain essen- 
tially the same in the primitive Euraphiinae 
and Pachylasminae, as do the number of pri- 
mary wall plates. Whether catophragmines gave 
rise to these two subfamilies independently, 
or the apparently more generalized shallow water 
euraphian Octomeris gave rise to the deep-water 
Pachylasminae, cannot be resolved at this time. 

Although the arthropodal structures seem to 
be similar, it is evident by shell characteristics 
that the euraphiines and pachylasmines are not 
closely related. Zullo (1963c:190) emphasized 
that further advances in shell arrangement differ 
in the two groups. Consequently, it is clear that 
the pachylasmines attained a six-plated condi- 
tion by development of a compound rostrum, 
and the euraphiines by loss of the carino- 

The transition from Euraphiinae to Chthama- 
linae is clearly by way of Euraphia, and con- 
sists primarily of the first and only significant 
change in the trophic apparatus. This change, 
the development of the so-called quadridentoid 
mandible of Pilsbry and others, is probably an 
adaptation, along with the specialized setae 
(grapples or cards) on the anterior cirri, to life 
in the high intertidal, as suggested by Pope 

The important feature of the quadridentoid 
mandible is probably not so much that there 
are four teeth, or that the second and third 
teeth are commonly bifid, but that the inferior 
portion rather than forming an angle support- 
ing a group or tuft of spines, is drawn out 
into a relatively long straight comb. Neverthe- 
less, Pope (1965:27) questioned the taxonomic 
value of this character. For example, she stated 
that the finding of "large individuals of certain 
AustraUan species (Chthamalus antennatus: 49) 
in which normally 4-toothed species have devel- 
oped only 3 teeth, or conversely, of 3-toothed 
species [Euraphia withersi: 43) with 4 teeth, 
is going to make the drawing of distinctions 
between Zullo's generic groups somewhat 

While there are difficulties in placing a few 
species in one or the other of these two groups, 
they are minor, and Pope herself explains most 
of them away. There is some variation in the 

number of teeth in E. withersi, and Pope 
(1965:43) pointed out that the majority of 
specimens will be found to have three teeth, 
and under any circumstance, the inferior angle is 
pectinated, not combed. Thus there would appear 
to be no real difficulty here. And with regard 
to C. attennatus, Pope (1965:49) stated, "Some- 
times mandibles of the right and left sides 
may vary and while the left one may have a 
s^e//af US-pattern for its lower tip, the right 
may have a "hembeli" one. However, in indi- 
viduals with somewhat hembeli-\\\ie jaws, the 
small, fourth double tooth can be seen, thus 
enabhng the real affinities of C. antennatus 
with Chthamalus to be recognized." 

Pope (1965:58) goes on and provides further 
evidence that alleviates her own objection to 
the recognition of Euraphia as separate from 
Chthamalus. In C. malayensis "juveniles, or 
during regeneration in certain individuals, the 
lower tip of the mandible is reminiscent of the 
Hembeli pattern." She then (1965:59) notes that 
mandibles regenerating after having been dam- 
aged take on a euraphian form, and further- 
more, that it seems as though juveniles and 
regenerating C. antennatus have to pass through 
a euraphian stage during the development of 
their much toothed and highly complex man- 
dibles. The juvenile situation is clearly onto- 
genetic; it is indeed an ancestral euraphian 
reminiscence, as suggested by Pope, and that 
a regenerating Umb would have to repeat the 
process is not surprising. Therefore, the dis- 
tinction between mandibles in the two groups 
recognized by Pilsbry and used informally by 
Nilsson-Cantell seem not only to be useful 
taxonomically, but they aid in elucidating the 
evolution of higher chthamaHds. A combed 
stellatoid mandible is seen elsewhere only in 
some Tetraclitidae, which also develop specialized 
cirral setae and occur high in the intertidal 
(Ross, 1970). 

Despite the great age of the Chthamaloidea, 
the group has been relatively conservative, 
undergoing little diversification with regard to 
both structure and habitat. None (with the pos- 
sible exception of certain Pachylasma on crinoids) 
has formed an obligate symbiotic association. 
The catophragmoid facies, first appearing in rocks 
of late Cretaceous age, was apparently an adapta- 
tion to high energy conditions along the shore 
and must have been abundant and widely distrib- 
uted in the past. Extant species have restricted 
distributions in the austral region and the tropi- 
cal Americas. 

The most advanced catophragmid, Chionelas- 
mus, and the relatively generalized chthamalid 
Pachylasma are presently the only deep-water 


members of the entire superfamily — all others 
are intertidal. Where Euraphia and Chthamalus 
occur together the former and more generalized 
occupies the higher reaches of the intertidal, 
the highest of all balanomorphs (Pope, 1965; 
Southward, 1964b). Littoral and shallow water 
habitats that would otherwise appear suitable 
for chthamaloids are occupied, presumably 
through competitive exclusion and other bio- 
logical interactions, by higher balanomorphoids 
and by balanoids. 


The Balanomorphoidea, proposed here, en- 
compasses the Coronulidae, Bathylasmatidae and 
Tetraclitidae (Figs. 1 and 5). Taken together 
one finds a suite of fundamentally primitive 
or generalized characters, including 8 wall plates, 
membranous basis, generalized opercular plates, 
no basidorsal point on the penis, and a labrum 
and cirrus III of intermediate form. 

Until recently the Tetraclitidae occupied an 
uncomfortable position as a subfamily of the 
Balanidae (Ross, 1968, 1970), whereas certain 
species of the Bathylasmatidae had been placed 
at one time in the Balanidae and at another 
in the Chthamalidae before being recognized as 
constituting a distinct family (Newman and Ross, 
1971). The suite of characters that unites the 
Tetraclitidae and Bathylasmatidae under the 
Balanomorphoidea is the same as that which 
prevents their being satisfactorily assigned 
to either the Chthamalidae or Balanidae. The 
same holds true for the coronulid Chelonibia. 
But in addition it has 8 wall plates, a con- 
dition that previously complicated understanding 
the evolution of Balanidae. Our proposed re- 
assignment of the coronulids to this super- 
family not only removes this difficulty, but 
also allows for further insights into the funda- 
mental organization and evolution of the 

The intermediate position of Hexelasma s.l. 
and related genera between Chthamalidae and 
Balanidae, appeared ideal in arguments for 
derivation of the latter (ZuUo, 1963c: 190). How- 
ever, it was shown (Bage, 1938; Newman and 
Ross, 1971:148) that the nature of the soft 
parts are not altogether intermediate, but rather 
possess many unique characteristics. Also, argu- 
ments requiring bathylasmatids as intermediate 
between chthamaloids and balanoids neglected 
the apparent eight rather than six-plated origin 
of the latter. Such arguments side-stepped what 
was considered a living representative of an 
early balanid, Chelonibia. At the same time. 

the bathylasmatids could not be considered 
directly derivable from chthamalids, and be- 
cause of Chelonibia they did not appear to be 
appropriate ancestors for the balanids. The 
obvious conclusion was that they must have had 
a separate origin, and probably then from a 
comparable pollicipoid lepadomorphan stock 
(Newman and Ross, 1971). 

The preparation of this revision afforded 
us the opportunity to take a fresh look at the 
matter. We found that the apparent, obstacle 
raised by Chelonibia was actually not a problem 
at all. As stated previously, and as will be 
given diagnostic documentation in the system- 
atic account to follow, Chelonibia and its aUies 
have hitherto been incorrectly placed among the 
Balanidae, and this has stifled our thinking 
on the matter. Once freed of this constraint 
the whole picture becomes simplified and emi- 
nently clearer. Chelonibia and other coronuhds 
appropriately fall in the Balanomorphoidea. 

Because of their extreme specialization as 
obligatory commensals of marine reptiles and 
mammals (Ross and Newman, 1967), what is 
known of the Coronuhdae, beyond Chelonibia, 
tells us nothing about the evolution of the 
higher Balanomorphoidea. It is the Bathylas- 
matidae that provides us with the data base 
from which further inferences can be drawn. 

The Bathylasmatidae form a natural group 
and we propose that it be divided into the 
subfamilies Bathylasmatinae and Hexelasminae 
(Fig. 5). Opercular valves are generalized in 
the former, and form a vertically oriented cone. 
In the latter, the opercular valves are more 
balanoid, and the plane of the scuta lies almost 
horizontal, across the orifice of the shell. Within 
the family, Hexelasma stands in an intermediate 
position between Bathylasma and Aaptolasma. 
However, it is more closely related to the latter 
and together they form the Hexelasminae. 

Many features in Aaptolasma herald the 
Tetraclitidae. The comparable form of the man- 
dible and labrum, the tendency for the third 
cirri to be antenniform, comparable opercular 
valves, and the peculiarity of the wall plates in 
being permeated by longitudinal chitin-filled 
tubes, are all characteristics that draw them 

In the original diagnosis of Aaptolasma, 
only a small number of differences could be 
assembled to distinguish the genus from Tetra- 
clita s. 1., but at that time no six-plated 
tetraclitids were known. However, it subse- 
quently became clear that Balanus (Austro- 
balanus) imperator Darwin was not just closer to 
Tetraclita than to Balanus, as Darwin (1854b:290) 
had recognized, but that it was a tetraclitid 



Figure 5. Radiation of the Balanomorphoidea: The CoronuUdae are specialized obligate commensals of large crustaceans, some 
fish, sea turtles and snakes, and marine mammals. The Tetraclitidae are, on the other hand, specialized for an intertidal 
existence. These two families apparently did not give rise to higher forms. If the Balanoidea arose from the Balanomorphoidea, 
as proposed here, it probably would have been via the hexelasmines, species of which are presently confined to the shelf (see 
text for further discussion). 


(Ross, 1971:266). Thus a distinction based on 
the number of wall plates, between Hexelas- 
minae and Tetraclitidae, fails. What remains 
is that the tetraclitids have radii (at least 
fundamentally), cirri II and III commonly are 
armed with bipectinate and other complex setae, 
and the labrum is wholly non-bullate; all ad- 
vances above the more generalized bathylasma- 
tid plan. 

In Aaptolasma, the solid wall is permeated 
by strips of chitin in much the same manner as 
in certain tetraclitids (e.g. Epopella). All other 
tetraclitids have tubiferous walls whose charac- 
teristics provide the distinguishing features of 
the subfamilies. 

There is a marked correlation between ad- 
vances in specialization of appendages, shell 
wall, and bathymetry. The most generalized 
forms in the Bathylasmatidae occur at the great- 
est depths; in fact Tetrachaelasma, a close 
relative of Bathylasma, is the deepest known 
balanomorphan (2,300 m). Members of the 
Hexelasminae occur on the shelf between ap- 
proximately 100 and 1,000 m. All members 
of the Tetrachtidae on the other hand, hke 
most Chthamaloidea, are intertidal or restricted 
to very shallow water. The hiatus between the 
low intertidal and 100 m or so is exploited 
by the Balanoidea. The Balanomorphoidea (ex- 
cept Tesseropora sp. on Heliopora, and the 
coronulids), hke the Chthamaloidea, do not form 
obligate commensal relationships as do many 
members or groups of the Balanoidea. 


It has been tacitly assumed that the Bal- 
anidae s. I. had an eight-plated ancestry, as 
did the chthamalids (cf. Newman et al, 1969). 
Darwin (1854b) pointed out the tripartite ros- 
trum of the chthamahd Pachylasma, and of the 
presumed balanid Chelonibia. Runnstrom (1925) 
reported that the rostrum in Balanus balanoides 
formed ontogenetically by fusion of the rostro- 
laterals, and this has been interpreted as a re- 
duction in the tripartite origin of the balanid 
rostrum. However, subsequent workers have 
failed to confirm this finding in this or any 
other balanid, much less a balanomorph. 

Direct evidence of a tripartite rostrum is 
found in Pachylasma and in Chelonibia, but 
as already discussed, these genera fall near 
the stem of the Chthamaloidea and Balano- 
morphoidea, respectively, and are not directly 
involved in the origin of the Balanoidea. It 
follows then, that there is no evidence for a 
tripartite rostrum (eight-platedness) in the stem 

of the Balanoidea. Nonetheless, it is appropriate 
that we review arguments to the contrary. 

Zullo (1963c: 190), following Darwin and Pils- 
bry suggested that the balanoids stemmed from 
the "Pachylasma-group." While not specifying 
which genera the group contained, he included 
Bathylasma ( = Hexelasma, in part), and pos- 
sibly Bathybalanus, as did Pilsbry (1916:291, 
328). At the time, inclusion of these two genera 
previously unknown to Darwin, made acceptance 
of the group as the stem from which the 
balanoids could have arisen more palatable, 
for not only did they have the proper type 
of rostrum but also the appendages were con- 
sidered to range from somewhat chthamaloid 
in Bathylasma to somewhat more balanoid in 
Bathybalanus. The labrum in Bathylasma, while 
not bullate as in chthamaloids, is relatively 
thick and lacks a deep median incision. Also, the 
third cirri are somewhat intermediate between 
the second and fourth pairs. The situation in 
Bathybalanus was thought to be comparable, 
although more balanoid. However, we have 
shown that Bathybalanus is in all respects 
a true balanid and that Bathylasma, while 
not a balanoid, is not a chthamaloid either 
(Newman and Ross, 1971:142). Furthermore, the 
s.l. transition from the chthamaloids to the 
balanoids by-passed Chelonibia, previously con- 
sidered the only eight-plated balanoid. The 
problem of Chelonibia was removed in the pre- 
ceding section of this paper, where it was 
shown that Chelonibia and its alhes were 
primitive balanomorphoids rather than balanoids. 
We are left then with the prospect that the 
principal balanoid groups descended from balano- 
morphoidans rather than chthamaloids. 

Early balanoids had a solid wall, as borne 
out by both fossil and ontogenetic evidence. 
The evolution of higher balanoids has in good 
part centered around the development of a com- 
plex wall, an evolutionary advance not achieved 
to any comparable degree in the chthamaloids 
(Darwin, 1854b), but paralleled in many re- 
spects in the higher balanomorphoids. At this 
point it is not difficult to envisage the Bal- 
anoidea as having descended from hexelasmine- 
Uke balanomorphoid ancestors, since the trends 
are already beginning there: comparably con- 
structed wall of six plates, labrum thin and 
broadly notched, third cirri somewhat modified 
as maxillipeds, and balanoid opercular parts. 

We include three families in the Balanoidea. 
The solid-walled forms, those included in 
Semibalanus, and those having irregular wall 
tubes of the non-balaninae type, such as found 
in Archaeobalanus, differ so markedly in wall 



Figure 6. Radiation of the Balanoidea: A few of the more generalized balanoids, such as Bathybaianus. are found in deep water. 
But most free-living forms occur in relatively shallow water, and in the intertidal (Semibalaninae and Balanidae) where upper 
limits tend to set the lower limits of the chthamahd zone. Archaeobalanines, on the other hand, are usually subtidal and many 
have formed obligate commensual relationships (i.e. Conopea on gorgonians, Acasta on sponges, Hexacreusia, etc, on scleractiniansl. 
It is from the archaeobalanines that the Pyrgomatidae, occurring on scleractinians (one exception, on sponges), are inferred to 
have been derived, Hkely polyphyleticaUy (see text for discussion). 


structure from the Balanidae s.s., that we 
relegated them to two separate families — 
the Archaeobalanidae (including the Archaeo- 
balaninae and Semibalaninae) and the Pyrgo- 
matidae (including the Pyrgomatinae s.s., 
Bosciinae and Ceratoconchinae). Thus arranged, 
the archaeobalanids, which first appear in the 
Eocene, are envisaged as having stemmed from 
six-plated hexelasmine bathylasmatids or bal- 

The Archaeobalanidae fall into two subfam- 
ilies, the more diverse Archaeobalaninae and the 
strictly intertidal Semibalaninae. The Archaeo- 
balanus-like forms with tubiferous walls have 
undergone the most marked diversification of 
any of the balanomorphs. They are well repre- 
sented in the intertidal even though the higher 
reaches have been left to the tetraclitid balano- 
morphoids and most chthamaloids. The semi- 
balanines which may have an Actinobalanus 
ancestry, apparently did not give rise to any 
higher taxa. 

Two families stem from the Archaeobala- 
ninae. They are fundamentally the solid-walled 
Pyrgomatidae and the tubiferous-walled Balani- 
dae. The Pyrgomatidae encompasses the coral 
barnacles and, while the monophyletic origin of 
the group is in question (Withers, 1929a; Ross 
and Newman, 1973; Newman and Ladd, 1974), 
the consensus is that some, particularly those 
contained in the principal subfamily, the Pyrgo- 
matinae, and possibly the Bosciinae, have 
descended from Armatobalanus (Zullo, 1969b, 
1967:127; Ross and Newman, 1973). The Cerato- 
conchinae apparently had a different and ap- 
parently non-armatobalanid origin (Newman and 
Ladd, 1974). 

The Balanidae, as envisaged here, may have 
stemmed from an irregularly tubiferous-walled 
ancestor having a calcareous basis such as 
Archaeobalanus. In the Balanidae the principal 
evolutionary advance was the establishment of a 
regular tubiferous wall in conjunction with an in- 
tricate dovetailing between the marginal portion 
of the internal ribs of the wall and the margins 

of the basis, thereby enabling an individual to 
continue to grow diametrically while maintaining 
a strong mechanical interlock with the sub- 
stratum (Newman et al, 1967). Perfection of this 
system, including delayed apphcation of an 
inner lamina to the internal ribs of the wall, 
produced the unique tubiferous structure dis- 
tinguishing balanids from all other Balano- 
morpha. Tubiferous walls occur in other Bal- 
anomorpha (Pyrgomatidae, Semibalaninae, and 
Archaeobalaninae among the Balanoidea, and 
the Coronulidae and Tetraclitidae among the 
Balanomorphoidea (Darwin, 1854b; Newman et 
al, 1967; Ross and Newman, 1967; Ross and 
Newman, 1973), but differences in ontogeny 
and the nature of the resultant structures 
indicate separate origins. 

The Balanidae is the most diverse family, 
and Pilsbry (1916:78 et seq.) began to group 
species of Balanus s.s., informally, into eight 
"series." However, he did not follow through 
with the matter in his monograph, and today 
only the "Series of B. amphitrite" is commonly 
referred to in the literature. We have at- 
tempted to follow Pilsbry s lead, and have ar- 
ranged the species of Balanus in six more or 
less natural groups. While some of these are 
readily recognizable by a number of characters, 
others have been assigned on the basis of un- 
defined facies similarities. Thus, while some of 
the groups may eventually become genera or 
subgenera, such a proposal at the present would 
be premature. Those species that we could not 
readily assign to one group or another are 
placed incertae sedis, at the end of the catalogue. 

A considerable part of the diversification 
of the Balanoidea has come about through 
establishment of obhgate symbiotic relationships 
verging on, but in only one case becoming 
wholly parasitic (Hoekia on the coral Hydno- 
phora, Ross and Newman, 1969). If the present 
epoch goes down in the fossil record as 
the "Age of Barnacles," as suggested by Darwin 
(1851a:5), it will in good part be due to the 
remains of symbiotic as well as free-living forms. 


The figures appearing on the following ten pages illustrate various features of the shell and 
appendages of balanomorphans. The figures are arranged sequentially, beginning with the shell and 
ending with the appendages. In those figures where comparisons are made, the arrangement is

In A, the left carinolateral and lateral wall plates as well as the left tergum and scutum have been removed revealing the in- 
terior of the mantle cavity containing the body of the animal as it resides when withdrawn. B, as A, but with the missing 
parts replaced and the cirri extended. The posterior three pairs of cirri (in Balanoidea and some Balanomorphoidea) form the 
cirral net while the anterior three pairs act primarily as maxillipeds. In C, it can be observed how the cirral net is formed 
and how the anterior cirri are positioned to aid in transferring food from it to the oral cone. Photographs courtesy of the 
American Museum of Natural History. 



Figure 8. Principal anatomical relationships: 

A. A balanomorph montage*, viewed from the right side, with right cirri extended from aperture formed between the 
occludent margins of the opercular valves, primarily the scuta. The six cirri are always biramous. The posterior three form 
the right half of the plankton-capturing cirral net, while the anterior three are reduced and otherwise modified, primarily 
as "maxiUipeds," for removal of food from the cirral net (cf. Figs. 14-161. Cirri are extended by circulatory hydrostatic pres- 
sure and withdrawn by retractor muscles. 

B. The tentorial operculum, composed of paried terga and scuta, attaches along its basal margin to the lower margin of 
the sheath and is operated by three principal pairs of longitudinal depressor muscles, a transverse adductor between the 
scuta, and circulatory hydrostatic pressure. 

C. and D. Exploded operculum illustrating scuta and terga respectively, (am, insertion of adductor muscle; rd, insertion of 
rostral depressor; Id, of lateral depressor; td, of tergal lateral depressor). 

E. Body torn free from its attachment in the operculum and surrounding mantle (carapace), exposing the adductor muscle 
(a), the oral cone or labrum surrounding mouthparts (6), the pedicles and proximal portions of the right cirri, the penis (c) 
originating between the sixth cirri and resting for the most part between the pedicles of the adjacent pairs, and the right 
caudal appendage or ramus of the caudal furca (d). 

F. Oral cone enlarged, illustrating arrangement of trophi, from left to right: Labrum (/) with mandibular palps (p) attached 
to each side, followed by mandibles (m) and first and second maxillae (max', max"). 

G. Basal region of a balanid penis illustrating gross form of the pedicel (a) and basidorsal point or horn (6). 

*A fully bullate labrum and caudal appendages are characteristics of lower chthamalids. while much reduced third cirri and a penis with a 
basidorsal point are characteristics of balanitis (see subsequent illustrations). A pair of outgrowths of the interior mantle lining extends into 
the mantle cavity in which the body of the barnacle resides. These, termed branchiae, are variable in structure between taxa, but their 
taxonomic value is yet to be determined. They have been little used in systematic studies and consideration of them has not been included here. 


Figure 9. The balanomorph wall; modifications of basic plan and nature of the basis: 

A. Wall of six solid plates; basis on left (not indicated) membranous, on right calcareous. In the latter, the basal margin 
of the wall may form some minor denticles, the older portions of which may appear as riblets on the interior of the wall, but 
the denticles form neither complex interdigitation with the basis nor anything other than very simple interlaminate figures 
in cross-sections of the wall (cf. Fig. 12A, B). 

B. As above, but with a "false basis" which may not, as in Euraphia intertexta, include the central portion of the 
membranous basis. 

C. Longitudinal sections of wall. Left, false basis, formed by successive layers of secondary calcification, in which fusion 
to the wall precludes further growth. Right, true basis indicating suture where marginal growth increments can occur. Var- 
iously thickened apical portions of wall (sheath) support the opercular valves. The sheath is ordinarily solid and its basal 
margin may become dependent (right). When a dependent sheath contacts ribs on the interior of the wall a type of tubiferous 
wall if formed, but the sheath does not constitute a true inner lamina (some coronulids and pyrgomatids). 

D. Tubiferous wall, in this case accompanied by a tubiferous basis. Well developed, uniformly deployed basal denticles form 
complex interdigitation with the basis which in turn is firmly cemented to the substratum. When, with growth, the inner por- 
tions of the denticles become secondarily fused, forming an inner lamina, the type of tubiferous wall seen here appears 
(Balanidae). If the denticles are simple, the interlaminate figures will be simple; if they have subsidiary lateral cusps, the 
interlaminate figures will be complex (cf. Fig. 12H, I). 

E. Longitudinal sections of wall. Left, a form with solid wall and basis where growth has been precluded by secondary 
calcification (false basis, as in some species of Euraphia). Right, a situation where transverse septa have developed in the 
tubiferous wall and basis, and where the cavity formed by the dependent sheath has become secondarily filled and/or cancellated. 
Aforegoing structural developments can occur in various combinations. 



Figure 10. The balanomorph wall; modifications of the basic plan. Fundamentally balanomorphs grow diametrically, increasing 
in height and basal width by depositing new shell around the basal parietal margins, and the size of the aperture is increased 
by additions to the lateral parietal margins to varying degrees (Darwin. 1854b). When lateral increments are negligible or ab- 
sent, the aperture is often enlarged by corrosion, as in Tetraclita. Other variations in the fundamental plan are illustrated 
A-C. Alterations in growth in gregarious species due to crowding. 

A. Pattern in forms such as Semibatanus balanoides and Balanus glandula (without or with carcareous bases respectively) 
where normally conical forms become columnar through elongation of the parietes. 

B. Alternative response to crowding, as seen in species of Megabalanus and members of the concavus group of Balanus. 
where elongation is primarily accompHshed by the formation of a cup-shaped basis. The basis may be permeated by one or 
numerous rows of tubes. 

C. Situation in some species producing a cup-shaped basis, such as some species of the concavus group and in Balanus 
laevis (illustrated), where the extensive cavity formed by elongation of the basis becomes secondarily transversely septate 
(cancellate or cystose). 

D. Growth in symbiotic forms, such as Acasta imbedded in sponges and Conopea (illustrated) occurring on gorgonians, 
in which a cup-shaped basis is formed. In the former it apparently assists in maintaining the apertural end of the barnacle at 
the surface of the growing sponge and (or) in enlarging the body chamber without forcing the wall above the surface of the 
sponge. In the latter, it elevates the barnacle well above the general surface of the gorgonian, the "keel" of its boat-shaped 
basis attaching firmly to the gorgonian axial skeleton. 

E-G. Coral barnacles keep pace with the surface of the coral, generally by elongation of the basis. 

E. As seen in species of Armatobalanus and Boscia, where elongation of the basis is not extensive and growth of the wall 
elevates the barnacle above the surface of the coral. 

F and G, where elongation is extensive and the wall plates grow so as to remain more or less flush with the coral surface, 
as in Eoceratoconcha and most members of Ceratoconchinae and Pyrgomatinae. In Eoceratoconcha and an early species of 
Ceratoconcha, the chamber formed by the basis is canceUate (F). while in most members of the Pyrgomatidae it is open (G). 



Figure 11. The balanomorph wall; parts and relationships of plates (schematic): 

A. Exploded eight-plated wall viewed from the right side. The plates are named, from left to right, the rostrum (R), 
paired rostrolaterals, laterals and carinolaterals (RL, L and CL respectively! and the carina (C). The central triangular portion 
of each plate is termed the paries (pi. parietes). The basal margin (blackened portion) contacts the substratum. Contacting 
surfaces between adjacent plates are stippled, and the portion seen from the exterior is termed the ala (pi. alae). The parietal 
margin overlapping an ala may develop a lateral portion which fills the space between it and the adjacent paries. This 
structure is termed a radius (pi. radii). Parietes can be sohd or permeated by longitudinal tubes; radii (except in Megabalanus 
and some Tetraclitidae) and alae are always solid. It can be observed that the rostrum and carina have alae, the rostro- 
laterals have radii on both margins while the laterals and carinolaterals have alae on their rostral and radii on their carinal 

B. An articulated eight-plated wall (as in lower Catophragmidae and Chthamalidae). 

C. Eight-plated wall in which the rostrolaterals have become inseparably but discernibly fused to the rostrum forming a 
"compound rostrum" (as in some species of Pachylasma and in Chelonibia). A true rostrum has alae and is overlapped by 
adjacent plates, while a compound rostrum has radii and overlaps adjacent plates. 

D. Compound rostrum where fusion demarcations are no longer discernible. May consist of fused rostrolaterals and 
rostrum, or fused rostrolaterals alone (see text for discussion of divergent views).

Figure 12. Wall structure in some Balanoidea. AH, transverse thin sections: I, photograph of basal margin. Increments 
resulting in vertical growth of the shell are due to deposition of new sheU along the basal margin of the plates. In primitive 
forms lacking a calcareous basis (most Chthamaloidea and the lower Balanomorphoidea and Balanoidea) transverse sections 
reveal little complexity in gross structure. With the advent of a calcareous basis there is an opportunity for a complex suture 
to form, interlocking the wall to the substratum through the basis. In solid wall forms the interlocking is generally accomplished 
by a regular array of simple denticles, the development of which is that of planar mineraUzed entities along centers of calcifi- 
cation, and these are visible as simple interlaminate figures in the older portion of the shell (A and B). If subsidiary 
denticles are produced perpendicular to the main denticle (as in I), the interlaminate figures wiU be arborescent (in solid walled 
forms as in C: in tubiferous walled forms as in E, G and HI. Some species without calcareous bases have tubiferous walls, and 
transverse sections commonly appear as in D. Some basically tubiferous walled species with calcareous bases have given up 
denticle formation and have all but completely filled irregularly formed tubes (F). 

Figure 13. Opercular plates of the Balanomorpha: A-G, Chthamaloidea; H-L, Balanomorphoidea; M-P, Balanoidea (all right 
terga and scuta, viewed from within). In the chthamaloids, terga tend to be triangular in outline (without spur, except in 
higher forms hke Chthamalus fragilis |G| where a rudimentary spur is developed), scuta never develop a strong adductor 
ridge, and the terga and scuta of each side tend to be deeply articulated especially in shallow-water forms (A and D-G). 

The situation in the balanomorphoids is somewhat intermediate between that seen in the chthamaloids and lower balanoids; 
a tergal spur is variously developed, an adductor ridge becomes prominent in higher forms (J-L) and the plates of shallow water 
forms are less deeply articulated. (In the first two superfamilies the tergum is never beaked and a spur furrow, where developed, 
is always open.) 

Lower balanoids tend to resemble higher balanomorphoids except that the adductor ridge is not particularly strong and 
the insertions of the scutal depressor muscles are simple. Closiu-e of the spur furrow (a result of the shaft of the spur becoming 
virtually internal), occasionally accompanied by production of a beak (O). apparently develops independently in various lines 
(within Semibalaninae, members of the Balanus concavus group, and Megabatanus). Partial or complete fusion of terga and 
scuta of each side occurs in all three superfamilies, but marked alterations in general form occur primarily in the coral sym- 
bionts (Pyrgomatinae, P). The whale-turtle symbionts (coronuUds) have reduced the opercular plates, and in Xenobalanus 
they have been lost completely. 

Figure 14. Trophi and cirri of the Chthamaloidea: A and D, Chionelasmus darwini; B and E, Euraphia intertexta: C and F, 
Tetrachthamalus oblitteratus. Trophi of lower chthamaloids are similar to those polUcipoid scalpellids — labra are buUate with 
crests variously concave but without a median notch (A and B); the mandibular teeth may have spinous superior margins (B); 
and the cutting edges of the first maxillae are usually stepwise or notched. In Chthamalinae (C) the mandibular teeth are 
never spinose, the second and third teeth are frequently bifid, a fourth bifid tooth is developed and the inferior portion is 
drawn out into a straight comb with the inferior angle supporting but a few sptnules, and the cutting edge of the first maxillae 
tends to be straight and slightly notched. 

The third cirri in general tend to resemble the fourth more than the second (E and F) but in Chionelasmus (D) even the 
second are more similar to the posterior ones. SpeciaHzed setae, ranging from bipectinate (E) to pinnate (F) are generally 
found on the second cirri. Posterior rami of the third cirri may be antenniform (F). apparently seasonally in intertidal forms. 
The caudal appendages or furca, a pair of uniramous appendages attached near the bases of the sixth cirri, and commonly 
found in lepadomorphans, are known in a few chthamaloids (D). 

Figure 15. Trophi and cirri of Balanomorphoidea; A and E, Chelonibia patula; B and F, Bathylasma corolliforme: C and G, 
Aaptotasma leptoderma: D and H, Epopella breviscutum; I, Tesseropora pacifica. Labra of balanomorphoids are similar to 
those of chthamaloids in being thick (although not bullate) and with variously concave crests (although there is a tendency to 
form a shallow notch). In Chelonibia (A) the labrum is distinctly notched and multidenticulate, in a manner reminiscent of 
Balanus amphitrite (Fig. 16 B). Mandibles of lower forms (A-C), in generally having four major teeth and pectinate inferior 
angles, are similar to lower balanoids (Fig. 16, A|. In higher tetrachtines (D) the inferior portion becomes combUke, much as 
in higher chthamaloids (Fig. 14, C), apparently an adaptation to life in the high intertidal. The first maxillae are essentially 
balanoid. The third cirri resemble the fourth more than the second (E-G), as in chthamaloids, or one or both rami are antenniform 
or bear specialized serrate setae (F, H and I). 

Figure 16. Trophi and cirri of Balanoidea. A and E, Solidobalanus (Bathybalanus) pentacrini; B, Balanus amphitrite amphi- 
trite; C and F, Balanus laevis; D, Hoekia monticulariae; G, Megabalanus psittacus; H, Balanus amphitrite inexpectatus; 
I, Armatobalanus (Armatobalanus) terebratus. Acasta conica and Acasta nitida respectively; J, Armatobakmus allium, K, Balanus 
nubilus. Labra of balanoids are generally thin and deeply incised; mandibles tend to have molariform rather than pectinated 
or combed inferior portions; first maxillae are undistinguished (B and C). In primitive species (A), the labrum has but a shallow 
notch and the mandible, in having an incisiform inferior portion, resembles that of the lower balanomorphoids. Marked de- 
partures from this facies are seen in commensal forms such as the wholly parasitic coral barnacle, Hoekia (D). 

The third cirrus always more closely resembles the second than the fourth, even in primitive species (E), and its rami 
are never antenniform. Rather, it is the anterior ramus of the first cirrus that takes on antenniform characteristics in 
some higher forms (F and K). Anterior cirri become variously thickened and in species without markedly speciahzed setae or 
spines, the anterior margin of the articles may become markedly protuberant (G). Complex setae, as seen in many chthamaloids 
and higher balanomorphoids, are not found in balanoids. Conversely, the so-called furcate (H) and multifurcate types 
found in certain species of the group of Balanus amphitrite (Henry, 1973) have not been observed in the first two 
superfamilies. On the other hand, compUcated arrays of spines commonly develop in balanoids (I and J), in free living forms, 
but especially in commensals of sponges and corals where they may be used to clear the aperture and prevent overgrowth by 
the host.

'Darwin (1854b: 290) noted, on the basis of several shell 
characters and the nature of the third cirrus, that Balanus 
imperator was closer to Tetraclita than to Balanus. but he 
nonetheless assigned it to Balanus. Pilsbry (1916: 2181 pro- 
posed the subgenus Austrobalanus, with Balanus imperator 
as the type species. However. Ross (1971: 266) noted that 
imperator was not a Balanus. but a six-plated tetracUtid, 
and subsequent studies on arthropodal structures confirms 
this affinity; Austrobalanus imperator is assigned to the 
Tetraclitidae herein. This change necessitates erecting a 
new genus for the remaining three taxa originally assigned 
to Austrobalanus by Pilsbry. We propose Notobalfinus Ross, 
herein (Gr. notos. southern, and Balanus). with Balanus flos- 
culus Darwin, 1854b, as the type species, and assign this 
genus to the Archaeobalanidae herein. The species assigned 
to Notobalanus may be characterized as follows: shell small, 
non-tubiferous: inner basal surface bears irregular ridges; 
radii narrow; basis calcareous, and non-tubiferous; scutum 
with crests for insertion of lateral depressor muscle.

Figure 17. The remains of Tetrachaelasma sp., blanket the sea floor at a depth of nearly 
2000m on the flanks of a seamount off Madagascar (26°29'S, 46°07'E). The relatively 
primitive balanomorphoid Tetrachaelasma southwardi was first discovered by the R/V 
Eltanin in the Antarctic Basin, off southern Chile and off Cape Horn at comparable depths 
(Newman and Ross, 1971). It is the only balanomorphan known to occur in the abyss. The 
calcareous deposits depicted here, composed of more than 90% calcitic barnacle remains, 
including rostra up to 10 cm in length, represent the remains of animals that once Uved on 
the seamount and were subsequently concentrated in the valleys and gorges around its 
flanks. Other accumulations of comparable barnacle content occur in the fossil record, but 
these developed in situ in shallow water. Photo courtesy of Robert L. Fisher, Scripps 
Institution of Oceanography.
