H. C. CHADWICK—REPORT ON THE CRINOIDEA. AT 
ANTEDON PALMATA (Miller). 
This species has been long known from the Red Sea, Miiller’s original 
description being based upon specimens from that locality and from Ceylon. 
The specimens in Mr. Crossland’s collection were obtained from the coral-reef 
of Misharif Island, Khor Dongola, and from between tide-marks at Suez, the 
collector at the latter place being C. Gordon Logan, Esq. 
In the specimens from Misharif Island the ossicles of the calyx and the 
proximal brachials are of a dirty-white colour in spirit, and the armlets are 
alternately and broadly banded with the same colour and dark brownish grey. 
The dorsal and ventral faces of the cirri show the same contrast of colour. 
The single specimen from Suez is of a-uniform purplish black. 
Distribution.—Red Sea, Ceylon. 
ANTEDON sAvienyi (Miller). 
Tn two examples of this species obtained from a depth of 4 fathoms in Suez 
Bay the number of armlets is thirteen. 
In both specimens the third and eighth brachial joints are syzygies, and 
others follow at irregular intervals of four to thirteen joints. 
Colour in spirit: purple, with purplish-white cirri and almost white 
pinnules. 
A single specimen obtained from a muddy bottom at a depth of 9 fathoms 
at Ul Shubuk was, when living, “whitish, with a violet tinge, and with 
patches of darker colour and of yellow.” From it were taken “ fifteen 
Ophiurids which lived with their arms twisted round those of the Antedon. 
The colour of these on the whole resembled that of their host.” 
This specimen has twenty armlets, each facet of the five primibrachial 
axillaries bearing a series of four secundibrachs, the fourth of which forms 
the axillary. The position of the second syzygy varies between the sixteenth 
and twentieth joints, and others follow at intervals of ten to twelve joints. 
Of two specimens obtained from a depth of 10 to 12 fathoms at Khor 
Shinab, one when living was brown and white, the other purple and white. 
One has fourteen armlets and the other eighteen, some of the arms dividing 
once only. The second syzygy is in some cases at the fourteenth joint, 
but usually varies in position between the seventeenth to the nineteenth, 
and others follow at intervals of seven to nine joints. 
A single specimen with twenty armlets was found living amongst coral at 
the anchorage at Salaka. Like one of those from Khor Shinab, its colour 
was brown and white. 
Distribution.—Red Sea, Ceylon,
