List of unidentified C r i u o i d s reported from western 



Australia. 



Amphimetra sp. 



At the British Museum I examined a specimen of a small species of 

 Amphimetra which had been obtained on Holothuria Bank in 15 fathoms. 



The arms of this individual are 50 mm long: the cirri have 22 seg- 

 ments of which the fifth and following bear long dorsal spines; -the longest 

 cirrus segments are not quite so long as broad. 



Tropiometra sp. 



What appears to be a curious new species of Tropiometra, charac- 

 terized by very slender cirri, was obtained by the "Alert" at Port Molle 

 in 1220 fathoms, and at Stat. 87 ; I have also seen a specimen of it 

 labeled ''western Australia". 



Compsometra sp. 



Thjere are in the British Museum eleven specimens of some species of 

 Compsometra near, if not, C. Loveni from Lewis Island in the Dampier 

 Archipelago. 



"Antedon sp." 



Prof. STUDER records an undetermined species, which he referred to 

 this genus, taken by the "Gazelle"' in 25 50,8' S. lat, 112 36,8' E. long, 

 (off Dirk Hartog Island) two knots from land at a depth of 45 60 fathoms 

 and a bottom temperature of 21 C. The specimen was of a deep violet 

 colour in life. 



Probably this was an example of Ptilometra macronema. 



"Comatula sp." 



Prof. STUDER records the capture of two ten-armed comatulids in 19 

 41,1' S. lat., 116 49,8' E. long, (off Port Walcott) at a depth of 91,5 meters 

 and a bottom temperature of 14,7 C by the "Gazelle"'. The colour of 

 one of them is recorded as purple, and of the other as pale yellow.
