tween Canso and Isle Madame as far as to Green Island. Near Canso, areas were 

 dredged from Tickle Island to the eastward, encircling Derabie Islands and Cranberry- 

 Islands, to Cape Canso, and at many places in the harbours and between the islands. 



Professor Prince, Professor Ramsay Wright, and others had the opportunity of 

 being on the Mackay-Bennett cable-repairing steamer, and I had the advantage of re- 

 maining on board for a couple of days in Dover Bay and saw what animals were 

 brought up on the cables as they were raised. 



The most successful places dredged during the two seasons were to the north-east of 

 Tickle Island and Durell Island, and outward from the bell-buoy in a line with the 

 channel entering Canso Harbour from the west. Here occur calcareous and other 

 sponges, a couple of species of sea-orange {P solus), Myriotrochus, Eupyrgus, and one 

 or two commoner Holothurians. Mussel shells dredged at the entrance to Grassy Island 

 Cove have Crepidulas attached. 



Although Canso is not a point exceptionally favourable from which to collect in- 

 veterbrates in numbers, yet, in one way or another, specimens were procured of most 

 of the species obtained at St. Andrew's, besides a few others. Its proximity to some of 

 the best fishing banks in the world is sufficient proof that there exist somewhere in the 

 adjacent waters vast quantities of smaller animals upon which the fishes feed. The 

 most valuable of these fisheries, as is well known, are the cod, haddock, pollock, 

 mackerel, salmon, halibut, the lobster, and the squid. 



As the member of the staff charged largely with the collection of specimens and 

 their storage for purposes of study, &c., a vast amount of the material obtained since 

 the station was founded has passed through my hands. In spite of an inadequate 

 supply of literature necessary for accurate determination of species, I have been able 

 to prepare a list,' which when finally revised will be a basis for future work. I 

 shall give here a list of the Porifera, the Coelenterata Avith the exception of the smaller 

 hydroids, and the Echinodermata, and propose in further papers to add to the present 

 cmtribn^ion, lifter the snecimens have been more completely worked over, and others 

 collected from more northerly areas.
