REPORT ON THE CRINOIDEA. 325 



not, owing to the radials lieing prolonged slightly downwards over the upper stem- 

 joints. Ten arms only, but the rays are in close lateral contact, the second radials l)eing 

 united all round, while the axillaries and the first two brachials have flattened outer 

 sides. Second and third radials and the first two lirachials respectively united by 

 bifascial articulation. Arms of about ninety joints,^ the lower ones bluntly wedo-e- 

 shapcd 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 joints, 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 foi-wards 

 into that of the epizygal. The first pinnules arc quite short, consisting oidy 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 wdth numerous, closely set, irregular plates. These extend on to the 

 arms at the sides of the ambulacra., which are altogether al)0ve 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 liand of limestone with its 

 edges cut into teeth which bear the covering plates. 



Colour in spirit, pinkish-white.

Three specimens reached me without any lal)els. Some or all of them were probably 



' I have seen no arm with more than eighty joints ; but the extremities of the arms are broken in all the specimens.
