76 KECORDS OF THE AL'STKAMAX .MLSp:rM. 



Mr. C. Hedley many years a<(o collected a large specimen <>F a llo'iflllu 

 at Masthead Island^ and banded it to Professor Haswell who shoAved it 

 tt) the senior author. It appeared to possess external characters and 

 size similar to those of J>. hagvelli. Unfortunately the worm has been 

 mislaid. It is quite likely that the Sydney specimens represent sti-ay 

 members of this species carried down the coast from the Queensland 

 Barrier Reef by the warm southerly current which is usually deflected 

 long- befoie it reaches Sydney, but which sometimes reaches that latitude, 

 bringing with it various invaders in the foi-m of tropical and siiljtropical 

 animals and plants, most of which fail to obtain a peimanent foothold". 

 Probably the Sydne}^ specimens travelled as trc)chophores. Their scarcity 

 would account for the apparent absence of males in both cases, especially 

 as it is stated that larva* require to come into contact with the female in 

 order to develop into males, otherwise they become females.
