that of its photographic portrait. The tentacles would also be of a much more 

 elongate contour. 



Discosoma Haddoni, the second species of giant Australian anemone discovered 

 by the writer on the Queensland coast, is chiefly distinguished from the preceding 

 type by the circumstance that its tentacles are spherical, except for their attachment 

 by a short cylindrical footstalk. This feature communicates to the expanded disc 

 the appearance of being, as it were, bestrewn with beads. Examples of this bead- 

 tentacled species of Discosoma were met with as far South as Shark's Bay, on the 

 Western Australian coast, and were there also accompanied by a commensal species 

 of Amphiprion altogether distinct from the orange-red fish with two white bands 

 previously observed consorting with this anemone in Queensland. The Shark's Bay 

 fish had three white bands, the centre of which was continued over the upper margin 

 of the second dorsal fin. The caudal and pectoral fins, and also the lips and irids, 

 were lemon-yellow ; otherwise the body and remainder of the fins were almost black. 

 It will probably prove to be a new species. The colours of these two giant 

 Discosomse were found to vary considerably. A dominant tint of the tentacles of the 

 species last referred to was a bright apple-green, or this tint mixed more or less with 

 lilac grey on a fawn-coloured disc. These hues were observed to prevail in examples 

 collected in both Shark's Bay and Torres Straits. In no instance, however, was the 

 subulate-tentacled species, Discosoma Kenti, met with in Western Australian waters 

 having bright blue tentacles, as not infrequently occurs on the Great Barrier Reef and 

 in Torres Straits. An example of this strikingly beautiful variety is figured in the 

 writer's previously cited volume. The representatives of this anemone observed at the 

 Lacepede Islands and elsewhere on the Western Australian coast were usually of a 

 light grey or lilac tint, with sometimes brighter lilac or crimson tentacle tips. 



The two species of fish, Amphiprion, referred to as found associated as 

 commensals with the Lacepede Islands Discosomae, were also met with by the writer 

 consorting with a smaller and altogether distinct species of sea anemone. The largest 

 examples of this anemone when expanded rarely exceeded, or even equalled, six 

 inches in diameter, and when growing as isolated individuals were never found 

 accompanied by commensal fish. Their more customary growth habit was, however, to 

 congregate in clusters in the fissures of the coral rocks, their adherent bases and 

 columns being thrust deep within the rock crevices, leaving their densely united 

 masses of extended tentacles alone visible. The Opelet Anemone, Anthea cereus, of the 

 British seas, commonly exhibits a similar aggregated growth plan. It was among
