Coll., vol. xii., 1885-1886, p. 301, pl. ii., figs. 2 and 2a; also 
No. 425, p. 68, pl. ii., figs. 2 and 2a, in Bull. of the U.S. 
National Mus., xxxvil., 1889. Zype locality.—North Atlan- 
tic, from 100 to 539 fathoms; also Chall. Zool., xiii., 1885, 
p. 52, pl. ix., figs. 8, 8b. Zocality.—Bermudas, 425 fathoms, 
coral mud; here by the artist’s mistake the clavicular process 
is omitted from the figure. But, judging from the illustra- 
tions and measurements given, our species differs in having 
a slightly longer rostrum, in being much smoother, and in 
its more spoon-shaped clavicle.
