REPORT ON THE CRINOIDEA. 325 
not, owing to the radials being prolonged slightly downwards over the upper stem- 
joints. Ten arms only, but the rays are in close lateral contact, the second radials being 
united all round, while the axillaries and the first two brachials have flattened outer 
sides. Second and third radials and thé first two brachials respectively united by 
bifascial articulation. Arms of about ninety joints,’ the lower ones bluntly wedge- 
shaped and the later joints nearly oblong or squarish, with raised distal edges so as to 
overlap slightly. A syzygy in the third brachial, another between the sixth and 
fifteenth jomts, and others at intervals of four to twelve (usually seven to nine) joints, 
The proximal face of the epizygal forms a sharp angle projecting backwards into the 
retreating distal face of the hypozygal, the dorsal surface of which projects forwards 
into that of the epizygal. The first pinnules are quite short, consisting only of about 
twelve joints, the lowest half of which are broad and flattened and the later ones quite 
small. This inequality gradually disappears as the pinnules increase in length, the 
lower joints becoming less broad and the later ones more elongated. Those on the 
middle of the arm are long and styliform, consisting of about twenty joints, the first of 
which are much broader than the rest. 
Disk covered with numerous, closely set, irregular plates. These extend on to the 
arms at the sides of the ambulacra, which are altogether above the arm-groove, and 
are protected by a continuous series of tolerably regular covering plates. There are 
no definite side plates on the pinnules, but only a narrow band of limestone with its 
edges cut into teeth which bear the covering plates. 
Colour in spirit, pinkish-white.
