logue, and the Coryne Cerberus withdrawn from it and from the 

 list of British species. 



Eudendrium insigne, Hincks. 



Since the description of this species was published {' Annals ' 

 for August 1861), I have met with it in some abundance at 

 Ilfracombe, and have had the opportunity of making a careful 

 examination of the gonophores. They surround the base of the 

 polype to the number of five or six, and present the same essen- 

 tial structure as those of Eudendrium rameum, described and 

 figured by Dr. Strethill Wright (Edin. New Phil. Joum. for Jan. 

 1859). The ovarian sac contains a single ovum, which is par- 

 tially enclosed by a looped process derived from the endoderm. 

 This loop overarches the egg and surrounds it, with the excep- 

 tion of its lower extremity, which is in immediate contact with 

 the wall of the sac. The gonophore is convex on both sides, and 

 presents a narrow edge when viewed in front. It differs in 

 form from that of E. rameum, which is oval, and in the size of 

 the endodermic band, which in the latter species almost entirely 

 encircles the ovum. The polype of E. insigne has the proboscis 

 white and the rest of the body of a dark-red colour.

XXXII. — Report of the Res^ults of Deep-sea Di'edging in Zet- 

 land, with a Notice of several Species of Mollusca new to 

 science or to the British Isles. By J. Gwyn Jeffreys, 

 F.R.S., F.G.S. 



To the Editors of the Annals of Natural History. 

 Gentlemen, 



Many scientific friends, who did not attend the last Meeting 

 of the British Association, wish to know the result of my dredg- 

 ing expedition to the " far North " of our coast-line ; and as 

 the Report will not be published for a long time, will you kindly 

 allow me to satisfy their inquiries by inserting an abstract of 

 the communication which I made to the Association ? I am 

 quite aware that I make this request at a late period, and that I 

 can only hope to have a corner of your valuable publication. 



I am. Gentlemen, 



Yours faithfully, 



J. Gwyn Jeffreys.

 Sept. 24, 1861. 



The Report was submitted by the author, as one of the General 

 Dredging Committee, not so much for the sake of announcing his 

 discovery of new species, as of maintaining certain views which he
