Hab. — Very common in Port Phillip ; Western Port ; Port- 

 land (Maples tone). 



Obs. — This species has hitherto been commonly known here as 

 Mytilus latus, Lamarck, a New Zealand species, but an examina- 

 tion of the type specimen of M. planulatus, Lamarck, by the late 

 Professor Tate, clearly indicates that our species must be known 

 by that name. In Professor Tate's Revision of the South Aus- 

 tralian Mollusca (T.R.S. S.A., vol. ix., p. 105), he refers to M. 

 chorus, Molina, but subsequently in his Critical Remarks on 

 Some Australian Mollusca (Id., vol. xxi., pt. 1. p. 49), he states 

 that M. planulatus is the M. chorus, of his revision, but " the 

 subordination of the name of this species to that of M. chorus, 

 Molina," he " has no opinion upon, having accepted Hutton's 

 views thereon." Professor Hutton in Appendix A to his Manual 

 of N.Z. Mollusca, p. 202, Remarks by Dr. V. Martens, quotes him 

 as sayinp- of M. dunkeri, from Auckland, " Probablj' not dunlxri, 

 but, in my opinion, chonis, Molina, which comf^s from Chili." In 

 Mr. H. Suter's List of New Zealand Species in the Transactions 

 of the N.Z. Institute, he omits any reference to either M. dun- 

 keri, or M. chorus. 



During the last few years considerable havoc has been worked 

 on this species by the large starfish Asterias calamaria, which 

 has become very common in many parts of Port Phillip. 



The type of this species is from King George's Sound, and is 

 in the Museum d'Histoire Naturelle, Paris.
