This herring was taken along the whole of the coast line 
explored, though it is improbable that it was trawled from the 
bottom, the specimens being more likely entrapped as the net 
was hauled to the surface: hundreds were washed through the 
large meshes, all appearing to be dead, their delicate bodies 
being unable to withstand the pressure to which they were 
subjected ; most of the examples preserved were skimmed off the 
surface with a hand net. 
Mr. W. Arthur collected some very interesting information on 
the habits of the sprat, publishing it in the paper above noted. 
Captain J. Bollons of the Government steamer ‘‘Hinemoa”’ 
has sent me this species from Auckland Harbour.
