Balanus porcatus Costa. 
M. J. Rathbun, 1905, p. 81. 
Off Nobska. — Rathbun. Crab Ledge, at Fish 
Hawk station 7608, 2 specimensf, one or both 
living, the largest measuring about 55 by 65 
mm. Off West Chop, July 17, 1908*, one liv- 
ing specimen, attached to a mussel shell. Spec- 
imens with opercular plates incomplete or 
lacking, and therefore impossible to identify 
with certainty, were taken in the eastern part 
of Vineyard Sound, at Fish Hawk stations 7523 
bis (2 on stones), 7524 (station number some- 
what doubtful, a single specimen), 7763 (1907 
repetition); also near Phalarope station n 
(Aug. 18, 1908). 
Balanus crenatus Bruguiere. 
Verrill and Smith, 1873, pp. 579, 381, etc.; M. J. 
Rathbun, 1905, p. 82. 
Piles of wharf at Vineyard Ha verify, clusters of 
large specimens taken by our collectors in 1906 
and 1909. The largest of these was 24 mm. in 
diameter at the base. Three large dead speci- 
mens, doubtfully identified* (opercular plates 
almost wholly lacking), were found attached 
to a shell, taken near the mouth of Buzzards 
Bay, at a 1907 repetition of Fish Hawk station 
7662. The largest was 18 mm. across at the 
base. These may be B. porcatus, however. 
On the other hand, those specimens which 
were doubtfully assigned to B. porcatus may in 
reality belong here. In view of the few du- 
bious records from the Survey dredging, we 
may well doubt the statement of Verrill and 
Smith that this species is “dredged abun- 
dantly in Vineyard Sound.” 
Balanus hameri (Ascanius). 
M. J. Rathbun, 1905, p. 83. 
“Off Chatham; off Marthas Vineyard;” from 16 
fathoms down (perhaps not properly to be in- 
cluded within the region). 
Balanus halanoides (Linnaeus). 
Verrill and Smith, 1873, p. 579, 304, etc.; M. J. 
Rathbun, 1905, p. 82. 
Generally distributed and enormously abundant 
on rocky shores, between tides; also found in 
great profusion upon piles and other sub- 
merged timbers. Darwin expressed the doubt 
whether this species ever lived below the low- 
est tides. In any case, not a single specimen 
has been found among all the barnacles 
dredged by the survey. 
Nauplii liberated in great numbers at Woods Hole 
in last week of December (1899). — Bigelow. 
Chthamalus stellatus (Poli). 
Sumner, 1909, p. 373. 
Abundant on rocks and piles everywhere along 
the shores of the region, being confined, appar- 
ently, to the intertidal zone. “ It extends con- 
siderably higher upon the boulders than does 
Balanus halanoides , with which, however, it 
is associated at a lower level. ... In local 
waters, so far as I have seen, Chthamalus never 
grows in such dense clusters as does Balanus 
halanoides, and indeed it appears unable to 
compete very successfully with the latter in its 
proper zone.” Despite its world-wide distri- 
bution, and its abundance locally, this species 
has not apparently been previously recorded 
for New England. (See discussion, on p. 190.) 
Eggs were taken by Dr. M. A. Bigelow during 
two different summers throughout the month 
of July. 
Family LEPADimE. 
Lepas fascicularis Ellis & Solander. 
Verrill and Smith, 1873, p. 579, 382, etc.; Bige- 
low, 1902, p. 65; M. J. Rathbun, 1905, p. 85; 
Pilsbry, 1907, p. 81 (“ Lepas fasciculatus’’: ap- 
parently a misprint). 
Vineyard Sound, and probably all local waters 
connecting with the open sea, growing in clus- 
ters upon drifting Fucus, Ascophyllum, and Sar- 
gassum or upon floating wood .sometimes in great 
abundance. Taken in June, July, and August. 
As regards reproduction, M. A. Bigelow states 
that when first taken locally during the summer 
season the eggs are mostly in advanced stages, 
though early stages have been found in June. 
Lepas pectinata Spengler. 
Verrill and Smith, 1873, p. 579, 382, etc.; Bige- 
low, 1902, p. 65; M. J. Rathbun, 1905, p. 84; 
Pilsbry, 1907, p. 81. (No local records, ex- 
cept by Bigelow.)
