 Professor Haswell who, in 1885, 1'eported what he believed to be B. virlilis 

 from Neutral Bay, Port Jackson ; noting at the same time that instead of 

 inhabiting narrow fissures in rocks it was fonnd under small stones just 

 above the limit of low water. Anatoniicall}'^ his specimens were said to 

 be identical with ]>. ci'n'di.^, except with regard to the repioductive organs 

 which, however, were immature. 



Whitelegge^ reported //. viridi^ from another locality in Port Jackson, 

 viz., Mosman Bay, obtaining his specimen under a stone during a 

 low tide. 



Shipley^ recorded the species from the Loyalty Islands, and from 

 the D'Kntrecasteanx Group. 



In considering the remarkable known distribution of this species, 

 viz., Mediterranean, North Sea and South Pacific, Sluiter' expressed 

 the opinion that a detailed examination of specimens from the last 

 named locality would show them to be distinct from the European 

 form. In the case of the S3'dney material we have found this view to be 

 justified. The specimens are not H.viridh, but closely resemble D.m'nior. 

 Full descriptions of the latter are not at our disposal, but even from the 

 meagre accounts that we have, it is clear that the two species are not 

 identical. If they had proved to be so, then, taking into account the 

 known distribution of 11. nil nor (viz., the Mediterranean) the occurrence 

 would have been just as remarkable as if they luid proved to be li.vlrldis. 

 It should be stated, however, that Ikeda^ has reported B. nil nor from 

 Japan, noting at the same time certain differences in the anal vesicles,, 

 which again differ from those of the Australian forms here described. 



We desire to express our indebtedness to the Director of the Aus 

 tralian Museum, Sydney, for allowing us to le-examine Mr. Wliitelegge's 

 specimen ; and to Professors W. A. Haswell, F.R.S., and S. J. Johnston 

 of the Sydney University for the opportunity to use Professor Haswell's 

 original material.
