of the axillaries have sharp edges, and these are continued along the sides of the first 
three or four brachials, after which the joints become more cylindrical in form. The two 
lowest are squarish, and both, but especially the first, are wider than their successors, 
which are longer than wide, and overlap rather 
sharply both at the muscular and at the trifas- 
cial articulations, but more so at the former. 
The first pinnule is almost always on the 
ninth brachial, and the pinnules are attached 
some little way behind the distal edges of the 
joints which bear them, so that the socket is quite 
distinct from the articular face. 
The joints of the six or eight lower pinnules 
which are enlarged to hold the genital glands 
have a sharp dorsal edge and broad thin sides 
which are much produced upwards, but the later 
pinnules are more slender. The disk is paved 
with closely set plates. 
Colour, in spirit, white. 
Locality.—Station 106. August 25, 1873; 
lat. 1° 47’ N., long. 24° 26’ W.; 1850 fathoms ; 
Globigerina ooze ; bottom temperature, 36°°6 F. 
(1°°8 C.). One specimen, now without stem or 
basal ring. 
Remarks.—This species may be readily dis- 
tinguished from the other three by the shape of 
the funnel formed by the united first radials, and 
the overlap of the arm-joints. As pointed out 
already (ante, p. 234), it was not at first dif- 
ferentiated by Sir Wyville Thomson from the 
larger form obtained in the Southern Ocean, to 
which he ultimately limited the name Bathy- 
crinus aldrichianus. In fact it seems to be the 
type from which the description of Bathycrinus 
aldrichianus was mainly drawn up. Although 
an entire specimen was obtained, the stem

appears to have separated from the head and to have been eventually lost; for 
otherwise we may take it for granted that the stem would have been drawn under 
Sir Wyville’s direction, together with the head belonging to it. In fact the upper 
part of the stem was drawn, together with the head, for the woodcut (fig. 15) which
