with seven of the specimens A. H. Clark (1914, Rec. W. Austi-al. Mus. i. 
p. 120) records from between Fremantle and Geraldton^ except that they 
apparently have a darker ground-colour. But they are all spotted v?ith 
uniformly small, circular greenish-yellow dots, generally quite distinct, but 
obscured in some of the darkest specimens. In view of the extraordinary 
diversity of colour of this comatulid, at the Murray Islands, it is remarkable 
that no diversity at all is shown at the Abrolhos. Possibly this western 
form may be worthy of a varietal name, but further field observations are 
necessary before a decision can be reached.

There are seven comatulids from Wooded Isle which seem to represent this 
species, tliough the colour is the yellow-brown characteristic of C. luteofusca. 
They range in size from those with arms 35-40 mm. long up to those whose 
arms exceed 100 mm. The disk is 7-12 mm. across. The arms range from 
12 to 23 in number. The cirri are few and weak, and have the characteristic 
form and proportions.

There are five specimens of this fine comatulid, but all are more or less 
badly broken ; two were " dredged outside Wallaby Grroup,'" while the other 
three were " dredged off Long Island." They are each about 12 mm. across 
the disk, and the arms were apparently about 100 mm. long. The cirri are 
XXI-XXVI, 26-32, 33-39, 36-41, with the segments all much wider than 
long and the dorsal teeth beginning at the 12th-15th segment. The calj'x 
and arras in each specimen are a dirty cream-colour, while the cirri are of 
that shade only at the base, becoming purple distally.

There are two light-brown specimens of this species collected along the shore 
at Wooded Isle. The arms are about 100 mm. long, and their segments 
proximally are so closely opposed to each other that the basal part of the 
arm is noticeably smooth and regular. The cirri are XXX-XXXII, 25-30 ; 
one specimen shows twenty-three additional cirrus-sockets. The cirri are 
less brown, more grey than the calyx. In one specimen there can be 
distinguished along the dorsal side of each fully-developed arm an incon- 
spicuous longitudinal whitish line.
