a median position; the opposing spine is short and _ transversely 
linear, forming a ridge across the entire dorsal surface of the joint; 
the terminal claw is stout, moderately curved, about equal to the 
penultimate joint in length; the ventral distal ends of the cirrus 
joints are more prominent than usual, and show a tendency to overlap. 
The radials are concealed; the first costals are short and broad, 
partially united laterally; the costal axillaries are very broadly 
pentagonal or almost triangular, about twice as broad as long, widely 
separated laterally; eight of the ten distichal series are 4 (8+4), 
the remaining two being 2; these last bear no palmars; there are 
six palmar series of 2 and two of 4 (3+4); there is a single post- 
palmer series of 4 (8+4) following a palmar series of 2. There are 
about 30 arms 90 mm. long, all the joints with very strongly produced 
and overlapping distal edges; the first three or four joints are dis- 
coidal, the remainder quadrate or almost triangular, about twice as 
broad as long. The first syzygy is between the third and fourth 
brachials, the next near the eleventh and twelfth, and syzygia occur 
distally at intervals of about four oblique muscular articulations. 
The distichal pinnule is about 16 mm. long, and not especially 
stout, the proximal joints with rather prominent distal ends, but 
not carinate; the first and second brachial pinnules are similar, but 
shorter, and the third is but 5 mm. long; the distal pinnules have 
the basal joints with prominent distal ends. 
Color (in spirits)—Brownish yellow, the cirri lighter with oc- 
casional dark bands.

The very strong imbrication.of the brachials, and the broad, 
rounded, transverse ridge, appearing spine-like in lateral view, on 
the cirrus joints, separate this species from all the other Pacific 
species of the genus, while the method of arm-division and the position 
of the first syzygy separate it from all the species known from the 
Atlantic.
