226 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXXIV. 
highly polished, at first squarish, then gradually becoming short; all 
the short and polished joints are furnished with sharp dorsal spines. 
Ends of basal rays visible as small tubercles in the angles of the 
calyx; radials concealed; first costals very short, with the edges some- 
what raised, and a pronounced median tubercle; costal axillaries 
rhombic, over twice as broad as long, the edges somewhat raised, and 
with a rounded median keel; distichals and palmars 2, similar to the 
costals, but with the edges not so prominent; the latter occurring 
2, 1, 1, 2. Twenty-eight arms (in the type) 100 mm. long; lower 
brachials discoidal, gradually becoming wedge-shaped (broader than 
long), then triangular; the rays and division series and the lower 
brachials up to about the fifteenth are sharply flattened laterally, the 
arms then becoming strongly compressed laterally, and developing 
strongly overlapping distal edges to the brachials, which in a lateral 
view appear as overlapping spines. Syzygia occur between the third 
and fourth brachials, again about the sixteenth and seventeenth, and 
distally at intervals of 2 to 8 (usually 4) bifascial articulation. 
The first pinnule is considerably longer and stouter than the fol- 
lowing, which decrease in length to about the fifth, after which they 
gradually increase distally, but never become very long. The first 
pinnule is not excessively stout, as in 7. hawadiensis, but 1s more of 
the proportions of those of 7. orion and 7’. fisheri. 
Color (an spirits).—Brownish yellow, the distal half of the cirri 
lighter. 
Locality.— Albatross Station No, 3963, Laysan Island Light bearing 
N. 56° 30’ K., 6.6 miles distant; 319 fathoms; white sand and broken 
shell. 
Two specimens. 
Type.—Cat. No. 22690, U.S.N.M. 
Remarks.—The presence of palmars and the slender cirri with only 
40 joints distinguish this species at once from the preceding. 
CHARITOMETRA LATERALIS, new species. 
Centro-dorsal very thick, discoidal or almost columnar, more rarely 
truncated conical, bearing about 30 closely crowded cirri. 
Cirri 30 mm. to 40 mm. long, stout, with 16 to 19 (rarely as few as 
15 or as many as 21) joints, the first about half as long as broad, the 
second almost as long as broad, the third rather longer than broad, the 
remainder about half again as long as broad; the last 4 or 5 joints 
have the median part of the distal dorsal edge rather prominent, and 
the penultimate bears a small opposing spine. 
Rays and usually all of the first costals concealed by the centro- 
dorsal; costal axillary low and broad, nearly three times -as broad 
as long. Ten arms 160 mm. to 180 mm. long; first two brachials very 
short, about four times as wide as long, oblong; the costal axillaries:
