222 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



In the remarks following his description of Antedon acuticirra Carpenter men- 

 tioned a specimen from Sydney, New South Wales, which he had seen in the Copen- 

 hagen Museum bearing the manuscript name Antedon australis Liitken. This is the 

 specimen from which the description given above (page 216) was drawn up. Carpenter 

 said that it has some resemblance to Antedon acuticirra. It has the same arrangement 

 of the division series, a few long and many-segmented cirri, and a large third pair of 

 pinnules. But it has relatively shorter axillaries and a shorter intersyzygial interval, 

 usually 7-9 instead of 11-16 muscular articulations. He said that without a more 

 detailed examination of the Copenhagen specimen than he had up to that time been 

 able to make it was difficult to be certain as to its identity with the one which he 

 described as Antedon acuticirra.
