Plates 149 and 150 give full structural details of the Common 

 Melbourne Crawfish, or Spiny Rock Lobster, which has not 

 been figured before, and which I have been at great trouble 

 to prove identical with that common at the Cape of Good 

 Hope, although quite different from that of Sydney and other 

 more northern localities. This " Southern " species abounds in 

 Tasmania, New Zealand and the Island of St. Paul, as well as 

 at the Cape of Good Hope. 



The succeeding decades will illustrate as many different genera 

 as possible, and will deal first, usually, with species of some 

 special interest and of which good figures do not exist or are 

 not easily accessible.
