on 



derm-fauna of Port Phillip. The region investigated by Mr. 

 Wilson seems to be one of much promise ; unfortunately 

 many of his specimens are young or solitary examples ; I 

 trust therefore that the publication of this list will induce 

 him and perhaps others also to make larger collections in the 

 Victorian waters, and especially to obtain good series of the 

 species collected. 



What follows must only be considered as a preliminary 

 notice of the Echinoderm-fauna of Port Phillip, as in many 

 cases the existence of new or incompletely known species is 

 merely indicated. As there is, however, no reason to suppose 

 that we shall not receive more examples from the locality, I 

 think it more advantageous to science to abstain from naming 

 or describing such specimens till we have a more complete 

 series. In the case of two new species of Antedon there is, 

 happily, quite sufficient material for description ; with the 

 Holothurians this is unfortunately not the case.
