EDITOKIAL NOTE. 
The Report on the Annelida Polych^ta, by Professor William C. MTntosh, 
F.R.S., &c., occupies the whole of the present volume, and forms Part 
XXXIV. of the Zoological Series of Reports on the Scientific Results 
of the Expedition. 
The preparation of this valuable Report has occupied Professor MTntosh 
over seven years, and it will be welcomed by all naturalists as a most laborious 
and painstaking contribution to Science. 
The Manuscript was received by me in fifteen batches, at various dates, 
between the 8th August 1884 and the 20th July 1885.
