corners rounded. Length to breadth 2.5:2. Side mouth-shields long and 
narrow, meeting within ; broadest at their outer end, where they join the side 
arm-plates, First under arm-plates irregular, transverse oval; the second 
similar, but larger ; those immediately beyond are transverse diamond-shape, 
with much rounded angles, Side arm-plates broad and thin, not meeting below 
till beyond the disk, widely separated above by the upper arm-plates, of which 
the first one is small and: triangular, the second quadrangular, with the outer 
edge widest and curved, and inner edge straight. Upper surface of disk, 
which is smooth and even, covered with thin, fine, ill-defined curved scales ; 
the radial shields are longer than wide, with edge much rounded, separated 
their entire length by small scales. Under surface covered by rows of 
scales somewhat larger than the scales above. Genital scales wholly covered 
by the scaling, except above, where they support an arm-comb of sharp, slender 
papille ; their free edge below carries a row of small conical papillae. Three 
tapering arm-spines, upper one longest, second and third about equal. Three 
or four small rounded tentacle-scales on each side of the month-tentacles, 
second and third pores having three on each side; those just beyond with 
four short sharp scales on the inner side. Color in alcohol, gray.

Special Marks. — Four arm-spines ; one long and high up, three short and 
low down. Radial shields touching without ; disk-scales angular. Disk thin, 
with rather delicate scales, Arms slender. 
Description of an Individual (Station 46). — Diameter of disk 9 mm. Width 
of arm close to disk 1.5 mm. Mouth-papilla three to four on each side, 
short and square, with a larger pointed one at apex of jaw. Mouth-shield wide 
pentagonal, with an obtuse angle inward, outer edge slightly curved, and outer 
corners rounded ; length to breadth 1:1. Side mouth-shields long narrow, 
wider without, tapering inward where they meet. First under arm-plate 
broad triangular, those beyond pentagonal, with obtuse angle inward, lateral 
sides re-enteringly curved and outer edge slightly eurved ; beyond the disk 
they gradually acquire the shape of a transverse oval, with a little peak without 
and within. Side arm-plates even, giving a tubular figure to the arm, meeting 
below, but separated above by the upper arm-plates, which are as long as broad, 
and in shape long hexagonal, with the three outer angles almost blended in a 
curve. Disk smooth, covered with small, delicate, irregular, ill-defined, closely 
soldered scales ; radial shields long pear-seed shape, overlapped along their 
edges by the surrounding scales, diverging inward and separated their entire 
length by a wedge of smaller and larger scales ; in centre of disk one large 
round primary plate, and another, in each brachial space, lying close to inner 
ends of radial shields, Disk, below, covered with very fine irregularly shaped
