Of the twenty- four species listed by Angas, I have not seen Lepi- 

 dopleurus vstulatus,* Tonicia Carpenteri, Cluetopleurarugosa or Micro- 

 plax Grayi. The type of T. Carpenteri was examined by Dr. 

 Carpenter who considered it a good species. It probably belongs 

 to the section Lucilina. Angas' Cluetopleura rugosa may possibly be 

 a young Plaxiphora, but it is with hesitation I hazard any conjecture 

 upon it. A note upon Microplax Grayi will be found in The Nauti- 

 lus for April, 1894, p. 139. The other species of Angas' list I 

 have identified with a consideralile degree of certainty, having 

 numerous specimens of all of them before me, as well as some addi- 

 tional forms lately discovered. The species collected by Dr. Cox 

 are as follows : — 



* Ischnochiion Kshilatiis Eve. occurs abundantly in South Australia, but 

 nothing I have seen from Port Jackson corresponds to this species.
