BULLETIN OF THE BUREAU OF FISHERIES. 
Family Amphiurid^. 
Ophiopholis aeuleata (Linnaeus). 
Verrill and Smith, 1873, p. 719, 400, etc.; 
Clark, 1904, p. 559; 1905, p. 6. 
Off Gay Head, 6 to 8 fathoms, rare.— Verrill. 
According to H. L- Clark (1904), this species is 
“regarded as a rarity south of Cape Cod ; ” he at 
one time expressed the belief that “the reported 
cases of its occurrence in Vineyard Sound are 
almost certainly cases of mistaken identifica- 
tion. ” Recorded from six of the seven Survey 
stations at Crab Ledge; likewise from at least 
one station in Vineyard Sound (probably Fish 
Hawk station 7570), a specimen from which 
was thus identified by Dr. Clark. Another 
undoubted specimen of the same species was 
dredged by the Marine Biological Laboratory 
steamer Cayadetta at the mouth of Vineyard 
Sound in September, 1909. 
Fish Hawk stations: 7603 (3, the largest 4 or 5 
inches in diameter)*, 7605, 7606 (several 
small), 7607 (several small), 7608 (many 
small)*, 7609 (4)*; also at 7570 ? (see above) 
and perhaps from other stations in Vineyard 
Sound.® 
Reported by both Verrill and Clark as being 
eaten in large numbers by cod. 
Amphipholis squamata (Delle Chiaje). [Chart 50.] 
Verrill and Smith, 1873, p. 720, 420, etc. (Am- 
phipholis elegans ); Clark, 1904, p. 539; 1905, 
p. 6. 
Vineyard Sound, occasional. — Verrill. Vine- 
yard Sound, common, especially just east of 
Nobska; Ram Island, Eel Pond, Crab Ledge, 
Sankaty Head; rocky or shelly bottom, gen- 
erally in cavities and interstices; “the com- 
monest and most widely distributed of the 
ophiurans in the Woods Hole region.” — Clark. 
Fairly frequent throughout Vineyard Sound; 
Buzzards Bay, at a number of stations; dredged 
in 4 to 15 fathoms, on various bottoms. — Sur- 
Amphi pholis squamata — Continued. 
vey. Hadley Harbor, on side toward Vine- 
yard Sound; head of Great Harbor, Woods 
Hole.— G. M. Gray. 
Fish Hawk stations: 6 7521 bis (?)*, 7537 bis (sev- 
eral small)*, 7538 bis*, 7560(1 small)*, 7564(1. 1 
inch across)*, 7571 (1), 7581 (2), 7628 (1), 7672, 
7674 (about 10), 7699*, 7703*, 7707*, 7730*, 
7743*- 7744*> 778° (?)*; Supplementary sta- 
tions (1907): 7780 (1)*; (1909): 7671 (1). 
Phalarope stations: b 55 (2), 116*, 118. 
Viviparous. In July and August the adults 
nearly always contain eggs and young. — 
Clark. 
Amphioplus abdita (Verrill). 
Verrill and Smith, 1873, p. 720, 433 ( Amphiura 
abdita)', Clark, 1908; Sumner, 1908, p. 319. 
Near Nobska Point and western shore of Buz- 
zards Bay. One arm taken at each of the fol- 
lowing stations: Fish Hawk 7776* (repetition 
made Aug. 6, 1907), Phalarope stations 163* and 
167*. — Survey. Ram Island*, Aug., 1907 (col- 
lected by G. M. Gray). Not listed by Verrill 
for any point within this region. According to 
the latter author this brittle star “buries itself 
deeply beneath the surface of the soft mud, 
and projects one or more of the long arms par- 
tially above the surface of the mud;” hence 
it is seldom dredged entire. 
Family Gorgonocepiiaud.f,. 
Gorgonocephalus agassizii (Stimpson). Basket-fish, 
“spider.” 
Verrill and Smith, 1873, p. 722 (Astrophyion 
agassizii): Clark, 1904, p. 561; 1905, p. 7. 
“First described from a specimen obtained ‘not 
far from the shoals of Nantucket,’ by Gov- 
ernor John Winthrop, in 1670 and 1671 . . . 
under the name of ‘ basket fish ’ or ‘ net fish . ’ ” — • 
Verrill. Crab Ledge. — Verrill, after V. N. 
Edwards; H. L. Clark; Survey. 
Ophiuroids , unidentified (probably for the most part Amphipholis squamata). 
Fish Hawk stations: 7532 (1), 7536 (1), 7547 (1), 7552 (1, very small), 7564 (1 small), 7568 (1), 7573 
(1 small), 7582 (1), 7599 (several), 7615 (1 small), 7633 (1 arm), c 7657 (1 arm), 7660 (1 arm). 
Supplementary station (1909) : 7643 (1 arm). 
Phalarope stations: 1 (1), 2 (1), 3, 8, 9 (fragment), 26, 28, 29, 81, no (1), 132, 146 (2). 
° Specimens from stations 7605, 7606, and 7607 (Crab Ledge) were identified in the field, but not saved for later examination. 
Hence the identity of these is somewhat doubtful, but not that of those from the other stations. Owing to a confusion of the 
records, we are not certain from which of the Vineyard Sound stations the single undoubted Survey specimen came. Some 
others, which were listed in the field under this name, were later found to be referable to the next species. 
b Here, also, probably belong most of the specimens listed as “Ophiuroids, unidentified.” 
c Perhaps Amphioplus abdita (Verrill). — H. L Clark.
