292 "ENDEAVOUR" SCIENTIFIC RESULTS. 



I have compared the above examples from Australia 

 with a photograph of the type of A. melanostictus kindly 

 supplied to me by Dr. P. Pappenheim of the Zoologisches 

 Museum, Berlin; as far as I can judge they seem to 

 represent that species, but have a slightly deeper body 

 and somewhat fewer dorsal and anal rays. A. ramsayi, 

 Ogilby, from Lord Howe Island may be this species.
