REPORT ON THE CRINOIDEA. 237 



Disk naked and more or less incised ; saceuli abundant at the sides of the pinnule- 

 ambulacra. 



Colour in spirit, — the skeleton brownish-white, and the perisome the same or 

 greenish -grey. 



Disk 12 mm.; spread reaching 22 cm. 



Locality. — Station 174 l (b, c, or d), August, 3, 1874; near Kandavu, Fiji; lat. 

 (about) 19° 6' S., long, (about) 178° 18' E.; 255, 610, or 210 fathoms; coral mud; 

 bottom temperature (at 610 fathoms), 39° F. Three specimens. 



Remarks. — These three individuals, which are somewhat variable in their characters, 

 but apparently belong to the same specific type, were obtained at Station 174 together 

 with the single example of Antedon similis. They all agree in the presence of one or 

 more post-palmar series, in the great development of the centro-dorsal, so as to partly 

 cover the axillaries, and in the absence of the sharp straight edges to the distichal and 

 palmar joints on the outer sides of the rays, which are so marked in Antedon similis 

 (PI. XLVII. fig. 1). They are therefore pretty clearly distinguished both from this 

 type and from its close ally Antedon brevicuneata. But they vary considerably in the 

 characters of their lower pinnules. Those at the outer side of each distichal group, and 

 more especially the outer pinnules of the rays, are generally rather longer and stouter 

 than the corresponding pinnules on the inner arms ; but I have been unable to make out 

 any great constancy in this arrangement, and it is much more marked in one of the two 

 specimens with the lower pinnules exposed than it is in the other. The third pinnule is 

 generally much smaller than the second (PI. XLVIII. fig. 2 ; PI. XL1X. fig. 4), but is 

 sometimes nearly or quite equal to it in size, a character which may occur on the inner as 

 well as on the outer arms. In the individual which shows the greater inequality of the 

 pinnules on the inner and outer arms (PL XLIX. figs. 3, 4), they are generally stiffer 

 and more styliform than in the more regular example (PI. XLVIII. figs. 1, 2). The latter 

 thus presents an approach toward Antedon conjungens, while the former rather resembles 

 Antedon protecta. These two species, however, have much less closely approximated 

 rays and a smaller centro-dorsal, which leaves the second radials visible as well as the 

 axillaries (PL XLV. fig. 1).

 Specific formula — A.2.2. y. 



Description of an Individual. — Centro-dorsal a thick disk, bearing about forty cirri 

 of twenty-five to thirty joints. The middle and outer joints are somewhat compressed
