Dr. Bailey adds further : — " All the above are 

 representatives of species which I had previously met with 

 in the neighbourhood of Port Erin. In my opinion, the 

 majority, if not all the species, were deposited on the 

 surface of the pond by the agency of wind currents, being 

 caught up and carried from the adjacent land. Several 

 must have reached the pond in this manner, as they are 

 wingless, or have the wings so aborted as not to be used for 

 flight." 



The Aquarium. 



The gratifying success of the Aquarium recorded in 

 the Reports for 1903 and 1904 has been greatly enhanced 

 this year. The wall tanks are now thoroughly and 

 permanently established, as is shown not only by the very 

 low rate of mortality amongst the inhabitants thereof, but 

 by the settlement and vigorous growth upon the glass 

 fronts and concrete walls of various invertebrates, the 

 larvae of which have passed from the sea through the
