536 EEPOET — 1893. 



sucli widely separated regions as Marion Island in latitude 48° S. and 

 the west coast of Greenland is very interesting, as also is the presence of 

 well-developed eyes in A. melanops and A. oculafiis, taken in from 5 to 

 25 fathoms ; while in A. Marionis and A. tenuimanus, taken in 100-200 

 fathoms, they are imperfect. It is very probable tbat it was this species 

 (J., melanops) to which Mr. Stebbing referred ' as having been sent to 

 him by Mr. Robertson from the Clyde.' 



In regard to the mollusca a large number of species have been 

 collected by the Committee ; and Mr. Alfred Leicester, of Liverpool, who 

 has examined and identified them, has drawn up a list of sixty-one 

 species which have not before been found off the south coast of the Isle 

 of Man, while the following twelve — Kellia siiborhicularis, Eulima inter- 

 media, Odostomia Luh'si, 0. cmioidea, Bissoa abyssicola, B. violacea, Ci/lichna 

 umhilicata, Philine scahra, Bulla utriculus, Melampus mijosotis, Trochus 

 Jielicinus, and Oyclostrema millepunctatum — are new records to the district. 



We have also taken the two brachiopods Crania anoviala and Tere- 

 hratula ca/put-serpentis, and the rare cephalopod Sepiola scandica (new 

 record), as well as the more common 8. atlantica. 



In regard to fishes, although most of the hauls on the expeditions, 

 having been taken with the naturalists' dredge, were not suitable for the 

 capture of fish, still the Committee, chiefly through the exertions of 

 Mr. P. F. J. Corbin, of the Fisheries Laboratory, University College, 

 Liverpool, have collected records of 114 species of fish found in the district, 

 and have added the following species, previously unknown : Solea varie- 

 gata, Gohius quadrimaculatus, and Argentina Kplnjrcena. 



In conclusion it may be stated that the Committee have conducted 

 eight expeditions between September and June, and have explored a 

 considerable amount of the Irish Sea around the Isle of Man, and 

 especially to the south and west. They have collected and identified 

 about a thousand species of marine animals, of which thirty-eight are new 

 records to the British fauna, 224 are new to the particular district (this 

 part of the Irish Sea), and seventeen are new to science. 



The Committee give with this report a chart (Plate IV.) showing the 

 area under investigation, with the zones of depths indicated, and a section 

 from Ireland to Lancashire, through the Isle of Man, showing the marked 

 difference in depth between the sea to the east and that to the west. 

 They are also preparing a larger and more detailed chart of the sea to 

 the west and south of the Isle of Man, where most of their dredging has 

 been carried on, in which the nature of the bottom and other particulars 

 will be given ; but they wish to make this chart more complete by the 

 incorporation of further observations before publishing. As the Com- 

 mittee are now applying to be reappointed, with a further grant to enable 

 them to carry on the work for at least another year, they hope that the 

 more detailed chart will appear in illustration of a second report at the 

 next meeting of the Association.
