Off New Jersey to the Arctic Ocean; northern coasts of Europe to the 
English Channel. Common in Vineyard Sound, 4 to 15 fathoms; Mas- 
sachusetts Bay; Casco Bay; Bay of Fundy, low-water to 60 fathoms. 
Greenland, 15 fathoms, (Liitken, as A. neglecta). Off New Jersey, 36 to 
38 fathoms, N. lat. 39° 54’, W. long. 73° 15’, (Josephine Exp., t. Ljung- 
mann). 3 
Mr. Ljungmann, in his latest paper, regards this species as distinct 
both from the Mediterranean species (Amphiura squamata), and the 
English and Norwegian species (Amphipholis elegans). The former I 
have here regarded as distinct, but consider the latter identical with 
the American form, the differences mentioned being slight and appar- 
ently inconstant. 
AMPHIURA ABDITA Verrill. (p. 433.) 
Amphipholis abdita Verrill, Amer. Jour. of Science, ser. iii, vol. ii, p. 132, 1871; 
this Report, p. 433. (See errata). 
Body plump, pentagonal; the interradial margins concave, and the 
angles, at base of arms, incised ; margin thick, rounded ; upper surface 
of disk covered with very numerous, minute, crowded scales, which en- 
croach more or less upon the radial shields and run up between them in 
a wedge-like area; lower surface thickly covered with still more minute, 
granule-like scales. Radial shields elongated, three or more times 
longer than wide, curved; the outer end geniculate or bent downward, 
forming a prominent angle above; they are divergent, and separate for 
their whole length, or barely touch at the outer ends, and are more or 
less concealed laterally and proximally by the encroachment of the small 
scales. Arms or rays, 16 times as long as the diameter of the body, 
or even more, slender, flexible, gradually attenuated to the tips. 
Six mouth-papille in each angle of the mouth, and two to four addi- 
tional small rounded papille, or tentacle-scales, near the extreme outer 
angle. Two of the mouth-papille, on each side, are placed close together, 
at about the middle of the edge of the jaw; the outer of these, which is 
about twice as wide as the inner, is flat, scarcely longer than wide, with 
the end obtusely rounded or truncate; the inner one is scarcely wider 
than thick, oblong, rounded at the end; in one case these two papille 
are united together. The third mouth-papilla is stout and rounded, 
obtuse, larger and longer than either of the others, separated from them 
by a considerable interval, and brought close to the tooth at the end of 
the jaw, beyond which it projects inwardly and downwardly.
