MARINE BIOLOGICAL STATION AT PORT ERIN. 75 



That brought us in touch with the surface zone through 



which the weight-net, the shear-nets, and the surface-nets 



had ranged. In this way we hope to be able to localise 



the constituents of the fauna obtained in a vertical haul 



such as III. 



The full details of the results obtained from these 300 



hauls taken in summer, as well as of the 276 taken at 



Easter and the 80 of the previous summer, will be 



given in a paper by Mr. Scott and myself, which 



we hope to have ready for the Annual Report of the 



Lancashire Sea-Fisheries Laboratory early in 1908 ; but in 



the meantime it may be of interest to readers if I give here 



one more list showing the results of a haul on Station V. 



inside the Wart bank (see fig. 4). One remarkable feature 



of this occasion was that the Hensen net hauled up from 



14 fathoms contained 150 specimens of what is considered 



by Mr. Scott to be a new species of Lejrtojisyllus, while 



the Xansen net used at the same time, and at the same 



depth, on the other side of the ship, caught twice as much 



material but not a single^ specimen of the new Copepod. 



The surface nets (I. and II.) are also somewhat divergent in 



their results.
