62 " ENDEAVOUR ' SCIENTIFIC RESULTS. 



actinal papulae make it an easy species to recognise. The 

 smallest of the three specimens has R=30 mm., and the more 

 or less isolated papulae are in about 4 irregular series. There 

 is only 1 prominent actinal spine for each 3 adambulacral 

 plates, until near tip of arm. The membrane between the 

 adambulacral plates has distinct non-calcified actinal areas 

 about .35 mm. wide by .25 mm. long. 



Locs. — Twenty-five miles south-east of Double Island 

 Point, Queensland, 33 fathoms. 



Thirteen miles north-east of North Reef, Capricorn Group, 

 off Point Curtis, Queensland, 70-74 fathoms.

There is a bare possibility that the little specimen with 5 

 arms from twenty-five miles south-east of Double Island Point, 

 Queensland, R = 25 mm., is not this species, but except for 

 the number of arms, I see no occasion for questioning it. 

 The species is abundant on the reefs of northern Queensland, 

 and it is quite possible that it reaches southward to twenty- 

 five miles south-east of Double Island Point. Of the speci- 

 mens figured, those from Bo wen, Queensland, and from Murray 

 Island, Torres Strait, are typical of the species ; the 4-rayed 

 specimen from Mauritius is exceptional and is, moreover, 

 poorly preserved. Three specimens. 



Locs. — Bowen, Queensland. A specimen with seven rays. 



Twenty-five miles south-east of Double Island Point, 

 Queensland, 33 fathoms. A small specimen with five rays. 



Echinaster glomeratus,i sp. nov. 

 (Plates xxii.-xxiii. ; Pig. 8.) 



R = 135 mm. ; r=25 mm. ; R=5.5 r. Br=25 mm. ; R = 

 5.5 br. Br at middle of ray =18 mm. ; at tip, 5 mm. Disk 

 large, moderately elevated as are the bases of the broad, 

 steadily tapering arms. Madreporite very small ; in holo- 

 type, only about 7 mm. from centre of disk but nearer the 

 margin in other specimens. Abactinal skeleton very coarse 



1. Glomeratus= grouped ; in reference to the arrangement of the 

 abactinal spines.
