NOTES. 51 
TRIPNEUSTES ANGULOSUS. 
This species is very plentiful on Lord Howe’s Island, where 
it attains a great size, often 6 to 8 inches in diameter; the 
young forms are frequently depressed, some scarcely an inch in 
height are two inches in diameter. They are eaten both in the 
raw and cooked state by the inhabitants. Some large specimens 
have also been dredged in Jervis Bay, a few miles south of 
Port Jackson; those from Port Jackson itself seldom exceed 
33 inches in diameter, and are usually white in color. 
EVECHINUS AUSTRALIA. 
Although dead tests are occasionally found thrown up on the 
sea beaches after heavy gales, this is a rare species on our coasts ; 
recently we have dredged a few small specimens off the 
“Sow and Pigs” reef, in Port Jackson. 
CLYPEASTRIDA. 
EcHINOCYAMUS AND FIBULARIA. 
We have quite a large number of small Urchins, dredged in 
from 15 to 30 fathoms off Port Jackson Heads, and northward 
towards the Seal Rocks near Port Stephens, which, in the present 
state of the literature at my disposal, I am unable to identify ; 
among them are undoubtedly several forms of the above- 
mentioned genera. 
CLYPEASTER HUMILIS. 
This fine species is very plentiful at Port Denison, and 
generally on the North-East Coast; it is found in from 3 to 10 
fathoms on sandy bottoms. 
ANOMALANTHUS TUMIDUS. 
The genus name for this species was given to the type 
specimen of Hchinanthus tumidus of TENIson-Woops_ by 
Proressor J. Bett, in his paper on the subject in the P.Z.S., 
1884, p. 40, pl. ii. It is a remarkable form, apparently allied to 
some fossil forms of the Oolite. It is to be regretted that no 
data as to locality or anything else was attached to the specimen, 
which was found in the old collection of the Museum. From 
the marks on the test it appears to have been speared with a 
flounder or flat-fish spear, still used by fishermen and amateurs 
in Port Jackson and Botany Bay, and was probably taken in 
the latter place, but we have no record as to the habitat of this 
single specimen,
