CRINOIDEA—OLARK. 13 
long as broad, and those following slowly increase in length, becoming about three times 
as long as broad distally. The side of the segments toward the arm tip bears a rather 
broad roughened line of fine spines and a slight and inconspicuous tuft of longer spines 
at the distal end, while the distal ends of the outer segments are slightly produced and 
finely spinous. 
P, is 7 mm. long with 16 segments. and resemble Ps. 
The distal pinnules are about 15 mm. long with 25, segments which have a broad 
roughened or minutely spinular line along the side toward the arm tip. 
Localities —Station 2, 318 fathoms, December 28, 1913 (two): Station 8, 120 
fathoms, January 27, 1914 (six); Station 9, 240 fathoms, January 28, 1914 (two); 
Station 10, 325 fathoms, January 29, 1914 (four); Station 12, 110 fathoms, January 31, 
1914 (eleven); no data (two). 
Distribution—Known only between Lat. 64° 32’ and 66° 55’ S., from Long. 
94° 17’ to 145° 21’ E. The bathymetric range is from 110 to 325 fathoms. 
Notes.—This species is described from one of the two specimens from Station 2; 
the other is similar to the one described. 
Other specimens show that the centrodorsal varies from low flattened hemispherical 
or broadly truncated conical in the larger examples to conical with slightly swollen 
sides, about twice as broad at the base as high, in the smaller. The arms in fully grown 
individuals vary from about 70 to 85 mm. in length. P, has from 26 to 36 (usually about 
30) segments. The longest cirri are 25 mm. long with 26-29 segments. 
The proximal brachials either have the middle portion of the distal edge 
greatly produced into a thin rounded triangular deeply serrate fin-hke process at right 
angles to the axis of the arm, or there may be on the dorsal surface an abruptly elevated 
triangular area thickly studded with minute spines with the base occupying about the 
middle half of the distal edge and the more or less rounded apex on, or very near, the 
proximal edge. Ina lateral view of the arms these elevated spinous areas appear as high 
rounded processes which are about their own width apart; but they may become much 
narrowed and restricted to the distal half or less of the brachials, in which case they 
appear as short and broadly rounded carinate processes. 
The entire absence of any median carination on the elements of the division 
series and first two brachials at once distinguishes this species from similarly small 
specimens of Anthometra adrian. 
In the British Museum there are several small comatulids collected by the 
“ Discovery ” at Winter Quarters of which I wrote in 1913 that they “are probably 
antarctica, but their small size renders accurate determination difficult.” It is quite 
likely that these will prove to represent the present species.
