was found in the stomachs of the Long-rough Dab and the Witch Sole 

 as well as amongst the contents of the small-mesh trawl-net. The 

 Trachelifer stage of Jaxea nocturna, Nardo, was collected in abundance 

 in the surface tow-net in Tobermory Bay, Sound of Mull, after dark, on 

 September 9th, 1901. The same organism has lately been recorded by 

 my son from the Barrow Channel, near Barrow-in-Furness.t The occur- 

 rence of Trachelifer at three different places seems to indicate a somewhat 

 extended distribution for this crustacean. 



Additional Note.

 Scotland, pt. iii., p. 252, pi. xviii. figs. 12-20. 



The copepod described under this name is identical with Selioides 

 bolbroei, Levinsen (Vidensk Meddel. Naturh. Forening Kjobenhaven. 

 1878, p. 373, Crust. Copep. parasit.) ; see also Seloides, op. cit. (1877). 

 This copepod is said to be parasitic on Harmothoe imbricata (Lin.). 



A marked peculiarity in this copepod is the position occupied by the 

 ovisacs, as shown by the drawing in the Report of the Fishery Board for 

 Scotland mentioned above. I have to thank the Rev. A. M. Norman for 

 drawing my attention to the paper by Levinsen, and also for permitting 

 me to examine the specimens he had received from that author.

I am obliged to Dr. Steuer of Trieste for pointing out to me that this 

 species is probably identical with Eunicicola Clausii, Kurz. — a parasite 

 on a species of Eunice — one of the Annelida,
