Menke (5), in 1843, reported the species as occurring very 

 rarely near Port Leschenault. This locality is not mentioned 

 in the "Australian Pilot." Mention is made of Cape 

 Leschenault, and of Leschenault Inlet, near Bunbury. 



Milligan (6), in 1850, reported the shell from the eastern 

 coast of Van Diemen Land, and remarked ''that as a per- 

 fect specimen of the same was obtained at Flinders Island 

 some years ago, amongst a vast number of shells of the paper 

 nautilus ( Argonautus argo), cast ashore there at same time, 

 it may fairly be set down as an occasional inhabitant of 

 these seas." 



Angas (7), in 1877, recorded the shell at Coff Harbour, 

 New South Wales. 



Brazier (8), in 1877, reported it from Coogee Bay, and the 

 mouth of the Bellenger River, New South Wales, and in 

 respect to the first locality remarked, ''I obtained one speci- 

 men at Coogee Bay, south of Sydney, thrown on shore after 

 the great easterly gale of 1857." 



Hedley (9), in 1893, exhibited a specimen found by White- 

 legge, at Curl Curl Lagoon, near Sydney, and remarked that he 

 had frequently seen it on the Queensland seaboard, and that 

 it had been noticed by Mr. Johnson as wrecked on the Tas- 

 manian coast. 



Cox (10), in 1897, found ''large numbers of rather broken 

 specimens of Nautilus pom^pilius thrown up in Eden Bay," and 

 remarked, "It is difficult to conceive how they get there; it 

 is an enormous expanse to be drifted away from any of the 

 Pacific Isles. Can it be possible that they are eaten by 

 whales, and that the shells are extruded as excrement? I 

 make this suggestion because great schools of whales come 

 in there, it is said, to rub themselves on the coarse gravel 

 bottom of the bay." 



MiGKATION AND DrIFT. 



Willey (11), in dealing with food and migration, says : "It 

 is also desirable to remember that Nautilus obviously draws 

 its supplies of food from the bottom of the sea, it is a ground 

 feeder. . . . When Nautilus has been taken, as a great 

 rarity, at the surface of the sea, it has, generally, if not 

 always, been found that the specimen was in a more or less 

 moribund condition. At the same time, with its known faculty 

 for swimming and migration, ... it is quite conceivable 

 that an individual specimen might occasionally wander away 

 from its home." It is quite probable, therefore, that if 

 conditions of food and temperature were suitable, a migrating 

 Nautilus would fully utilize ocean currents. Based on the
