REPORT ON THE ANNELIDA. 
XI 
It may be deemed by some an inconvenience to refer to several plates for the 
structural and other details of the same species, but the study of the Annelids is a matter 
that requires so much deliberation that the inconvenience is comparatively slight. 
Moreover, it was found that different treatment was required in the execution of the 
structural plates. In the explanations of the latter, it has not been thought necessary to 
go into details, since this had already been done in the text. 
I have to acknowledge the unfailing courtesy of Dr. John Murray, who, after the 
death of Sir Wyville Thomson, became Director of the Challenger Commission, of Mr. 
Hoyle, M.A., M.R.C.S., Naturalist to the Commission, and Mr. Monteith of the same 
office, who suggested improvements in passing the work through the press. Prof 
Moseley also kindly forwarded a fine specimen of the Hexactinellicl Sponge {Cratero- 
morpha meyeri) infested by Syllis ramosa, from the Oxford Museum. It was procured 
off the Philippines by Capt. Chimmo of H.M.S. “Herald.” 
To Prof Flower, Director of the British Museum, as well as Prof Jeffrey Bell 
and Mr. S. 0. Ridley of the same institution, I am much indebted for their aid in 
examining the Annelids in the collection. I am especially obliged to Prof Jeffrey 
Bell for his patient and courteous attention in this respect. Lastly, Dr. Murie’s valued 
aid in the Library of the Linnean Society deserves my cordial acknowledgments.
