88 BULLETIN OF THE 
Arcular, with the curve inward. Disk covered with rounded, flat, thin, closely 
joined plates, among which may be seen a central rosette of primaries, and 
two larger plates in each interbrachial space. Radial shields short, wide, 
rudely semicircular, touching along part of their length, separated within by 
small wedge-like scales, The interbrachial space on the under surface is nearly 
covered by the large mouth-shield. The genital scales are broad and slightly 
curved, and bear rather stout tooth-like papilla. Outside the mouth-shield 
are two rows of small thin semicircular scales. The papille of the arm-comb 
are flat, squarish, and separated, and are borne by a semicircular plate about 
as broad as long. Three minute arm-spines, pointed and standing well up on 
the outer edge of the side arm-plate. Tentacle-scales of the innermost pair 
of pores small, semicircular, usually two on either side. The rest of the ten- 
tacle-pores have usually one large on the outer side, and three or four smaller 
on the inner side, Color in alcohol, nearly white.

Special Marks. — Three minute arm-spines. Disk covered by small irregu- 
lar scales, small separated radial shields, and very large mouth-shields, Disk 
high, Basal under arm-plates about as long as broad, Arms high and 
rounded, 
Description of an Individual (Station 157).— Diameter of disk 15 mm. 
Length of arm about 37 mm. Width of arm, without spines, close to disk 
3.5mm. Mouth-papille small, conical, widely spaced, diminishing in size 
from within outward ; about five on each side and a group of three larger ones 
at apex of jaw. Mouth-shields very long, pentagonal, with an obtuse angle 
inward, lateral sides re-enteringly curved, and outer edge rounded ; length to 
breadth 3.5: 3. Side mouth-shields short, meeting broadly within, where 
they are wider than without; occupying only the inner end of the mouth- 
shields. First under arm-plate triangular, with an angle inward, and outer 
edge curved ; beyond, the plates are four-sided, thick, with outer and inner 
edges nearly straight, and lateral sides re-enteringly curved ; beyond the disk 
they become hexagonal; their surface has a minutely crystalline appearance. 
Side arm-plates swollen, and not meeting below for some distance beyond disk. 
Upper arm-plates broader than long, thick and swollen, with outer side curved 
and longer than the inner, which is nearly straight ; lateral sides re-enteringly 
curved, Beyond, they are bounded by a long curve within and a peak with- 
out. Disk smooth, arched, and very thick, covered above with small thin 
plates, having a minutely tuberculous or crystalline appearance ; in the centre 
are six circular primary plates, separated by others irregularly shaped and 
angular, which also fill the interbrachial spaces. Radial shields small, short, 
and thick, rounded triangular, with an angle outward, separated their entire
