actinal papule make it an easy species to recognise. The 
smallest of the three specimens has R=30 mm., and the more 
or less isolated papule 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 Bowen, 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,! sp. nov. 
(Plates xxii.-xxi.; Fig. 8.) 
R=135 mm. ; r=25 mm.; R=5.5r. Br=25mm.; R= 
5.5 br. Br at middle of ray=18 mm. ; at tip, 5mm. 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.
