widest specimen is .91 as wide as long ; the narrowest is .82. 
In the highest specimen the vertical diameter is .41 of the 
length ; in the flattest it is .29. The colour is some shade of 
brown, usually with a greenish tinge. Several of the speci- 
mens are slightly asymmetrical in one way or another. Ten 
specimens. 
Locs.—Six miles east of Cape Hawke, New South Wales, 
47-50 fathoms. 
Shoalhaven Bight, New South Wales, 15-45 fathoms. 
East of Babel Island, Bass Strait, 65-70 fathoms. 
CLYPEASTER TELURUS, H. L. Clark. 
Clypeaster telurus, H. L. Clark, Rec. West Austr. Mus., i., 
1914, p. 166. 
The unique holotype of this species was taken on the 
coast of Western Australia almost directly across the Aus- 
tralian continent from Fraser Island, Queensland, but a 
prolonged critical study of these Clypeasters fails to show 
any character or combination which will distinguish them 
from it, except that they do not have the posterior inter- 
radial margin depressed appreciably. They are all larger 
than the holotype, the largest measuring 145 x 135 x 20 mm. ; 
as a species character, it seems to be true that the breadth 
exceeds .90 of the length, while the height is less than .15. 
There are about 400 primary tubercles to a square centimeter 
of the aboral surface. The unpaired anterior petal is 39 mm. 
long and has 52 pore-pairs. The periproct is 8-12 mm. from 
the posterior margin, and this considerable distance, taken in 
connection with the thin, almost fragile, test, and the form of 
the petals, makes it easy to distinguish this species from 
C. humilis, which is its nearest relative. Tridentate pedicel- 
lariz, with valves .25-.75 mm. long, are common on the oral 
surface. The colour of these specimens is more or less 
purplish-brown. 
Loc.—Off Fraser Island, Queensland. Four specimens. 
CLYPEASTER VIRESCENS, Doéderlein. 
Clypeaster virescens, Déderlein, Arch. f. Naturg., li.i., 
1885, p. 102. 
This individual is 105 mm. long, 95 mm. wide and 19mm. 
high. The colour is yellow-brown with a distinct greenish 
tinge orally. Although none of the Japanese specimens at
