994 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. 
squarish, the fifth half as long again to twice as long as broad, smaller 
distally than proximally, the terminal quarter with a polished sur- 
face like the succeeding, the proximal! three-quarters with a dull sur- 
face like the preceding Joints; this jomt has a blunt spine on its dor- 
sal distal edge; sixth joint about half again as long as wide, eighth 
squarish, the following remaining practically uniform; the sixth and 
following joints bear sharp dorsal spines. 
Radials concealed; first costals short, about three times as broad as 
long, with a rounded median tubercle; costal axillaries almost low- 
triangular, about twice as broad as long, the center strongly convex; 
distichals 2 similar to the costals. Thirteen arms (in the type) 
120 mm. long; first and second brachials oblong, about twice as wide 
as long, the former united interiorly for about two-thirds of their 
length; third and fourth brachials (syzygial pair) about as long as 
wide, the hypozygal much larger than the epizygal; following eight 
brachials shghtly wedge-shaped, broader than long, then becoming 
more obliquely wedge-shaped or almost triangular, about as long as 
wide, and distally quadrate again and finally elongate. Syzygia oc- 
cur between the third and fourth brachials, again between the thir- 
teenth and fourteenth to fifteenth and sixteenth (more commonly the 
former) and distally at intervals of three to seven (most commonly 
four) bifascial articulations. The costals, distichals, and lower 
brachials are in close apposition and flattened laterally. 
First pinnule 7 mm. long with 15 or 16 joints, the first 3 to 5 large 
and strongly carinate, about as long as wide or somewhat wider than 
long, the remainder more slender and slightly longer than wide; 
second pinnule shorter, somewhat less stout at the base, and taper- 
ing evenly to the tip, the lower joints not being disproportionately 
large, though they are somewhat carinate; third and fourth pinnule 
like second, but progressively shorter; the fourth and following pin- 
nules are 5 mm. long with about 12 joints, shehtly longer than broad, 
flattened and markedly carinate, the distal angles of each joint over- 
lapping the base of the next succeeding, producing a strongly serrate 
lateral outline; the joints are all subequal in size, so that the pinnules 
appear generally stouter, though smaller, than those preceding; 
these gradually become longer, reaching 9 mm. distally, but preserve 
their thin, flattened character, and the serrate appearance of the 
lateral edges. 
Color (in life)—Arms cadmium orange, darkest on pinnules; 
cirri bright lemon yellow (Fisher).
