14 AUSTRALASIAN ANTARCTIC EXPEDITION. 
In 1915 I recorded and figured what I considered at the time to be a half grown 
individual of Promachocrinus kerquelensis with 5 rays and 10 arms which had been dredged 
by the “ Gauss” in 222 fathoms (400 metres) in the vicinity of Gaussberg. In this 
Specimen the cirri were said to be 52 mm. long with 33-37 segments. The centrodorsal 
is conical, 4 mm. broad at the base and 4 mm. high, and shows no resorption at the 
dorsal pole. The dorsal surface of the earlier brachials is thickly beset with fine spines. 
This specimen was figured natural size (fig. 1a) and also twice natural size (fig. 10). 
The original photographs were not very clear, and the background was blocked out by 
myself. While the larger figure does not show the scalloped profile so characteristic 
of the arm bases of this species, this is mdicated in the smaller figure on the left side. 
so that it may have been inadvertently obliterated in the larger figure in the blocking 
out process. 
I am now inclined to believe that this so-called 5-rayed individual of 
Promachocrinus kerquelensis is in reality a specimen of Florometra mawsoni, and that the 
cirri described (52 mm. in length with 33-37 segments) may have come from a different 
individual. 
Remarks.—There seems to be no doubt that this species is properly referable to the 
genus Florometra, from the other species of which it differs only in the much smaller size 
and in the greater development of the modification of the dorsal surface and distal 
edges of the earlier brachials. 
The genus Florometra ranges from Cape Horn northward along the western coasts 
of South and North America to the Bering Sea, westward along the Aleutian Islands, 
and southward along the Pacific coast of Japan to Sagami Bay in southern Japan. 
It has not previously been found in the Antarctic seas. 
Genus ANTHOMETRA A. H. Clark. 
ANTHOMETRA ADRIANI (Bell). 
Localities.—Station 1, 354 fathoms, December 22, 1913 (twenty-three); Station 2, 
318 fathoms, December 28, 1913 (four); Station 3, 157 fathoms, December 31, 1913 
(three); Station 8, 120 fathoms, January 27, 1914 (one); Station 9, 246 fathoms, 
January 28, 1914 (two); Station 12, 110 fathoms, January 31, 1914 (fifteen). 
Distribution.—Confined to the shores of the Antarctic continent where it is 
generally distributed and common, being. except for Promachocrinus kerguelensis, the 
most abundant crmoid. The bathymetric range is from 110 to 354 (? 500) fathoms. 
Colour in life-—Arms flesh colour, the pmnules pink. 
Notes.—The longest cirri (Station 12) are 90 mm. long with 81 segments. The 
first segment is about four times as broad as long, the next three are about three times 
as broad as long, the fifth-is slightly over twice as broad as long, the sixth is nearly as 
long as broad, the seventh is one third again as long as broad, and the ninth-twelfth 
are nearly twice as long as broad, The segments following very slowly decrease in length
