Family AXTEDONID/E Norman 



COMPSOMETRA species 



i. Lewis Island, Dampier Archipelago, Western Australia.— 

 Eleven specimens, possibly referable to C. loveni. 



HATHROMETRA species 



Antedon dentata 1884. P. H. Carpenter, Proc. Roy. Soc. Edinburgh, vol. 12, 



p. 362 (1,2). 

 Antedon tenella 1888. P. H. Carpenter, "Challenger" Report, Comatulae, 



p. 169 (1,2). 



1. "Porcupine" Station No. 57. — One specimen partially decalci- 

 fied and not specifically determinable, though it appears to belong 

 to H. prolixa. 



2. "Porcupine" Station No. 54. — One specimen; the cirri are 

 stouter than those of H. sarsii; the longest cirrus segments are about 

 four or four and a half times as long as the median diameter, not 

 greatly constricted centrally ; ths centrodorsal is low and conical. 

 Probably this is a young specimen of H. prolixa.
