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 

 3^ 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. 



CLYPEASTR1DA. 



ECHINOCYAMUS AND FlBULARIA. 



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 Ecliinantluis tumidus of TENISON-WOODS by 

 PROFESSOR J. BELL, in his paper on the subject in the P. Z. S., 

 1884, p. 40, pi. 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.
