794 " THETIS " SCIENTIFIC RESULTS 



Specimens in the Australian Muse%im Collection. — Port Jackson 

 — Five specimens. 



Additional Austrcdian Record. — Port Phillip. 



Remarks. — In examining the Comatulids in the British 

 Museum I was greatly surprised to find that the types of Bell's 

 Antedon incommoda consist of two specimens of the form which 

 I had called Compsometra lacertosa, and one yowng Ptilometra ; 

 Bell himself placed incommoda unhesitatingly in the synonymy of 

 his previously described loveni or pumila. 



CRINOIDS KNOWN FROM THE DEEP WATER 

 ABOUT AUSTRALIA. 



While the present Memoir is concerned only with the littoral 

 and sublittoral Crinoids of Australia, some mention should be 

 made of such species as are known to occur in the deep sea 

 surrounding that continent. While on her epoch-making voyage 

 around the world, the "Challenger" made three hauls off the 

 Australian coast at which Crinoids were obtained in depths 

 varying from 950 to 2,600 fathoms; a number of years after- 

 wards Capt. F. Worsley, of the cable-repair ship " Sherard 

 Osburn," while working on the Sahul Bank, secured several very 

 interesting species which were reported upon, after the death of 

 Dr. P. H. Carpenter, to whom they were originally sent, by Prof. 

 F. J. Bell. Thanks to the kindness of Dr. Nelson Annandale, 

 of the Indian Museum, Calcutta, the specimens collected by Capt. 

 Worsley belonging to that institution are now before me. The 

 species obtained on the Sahul Bank are comparatively shallow 

 water forms, and probablj' came from near the 100 fathoms line 

 — at least most of them. They include the only stalked Crinoid 

 so far known from the vicinity of Australia.
