Were it not for the presence of the ventral spines, I should not 
hesitate to identify this specimen with Lemboides australis (Haswell). 
Thinking that these spines might have been overlooked, I appplied to 
Prof. Haswell, who kindly looked through the Crustacea in the 
Macleay Museum, Sydney, but failed to find either the type or any 
specimens of the species in question. Dr. E. A. Briggs also obliged 
me by examining the collection in the Australian Museum, without 
any better result. So that one must regard the type of Haswell’s 
Microdeutopus australis as in all probability lost, and institute a new 
species for the South African form.
