to the conclusion in the end that it was still much too 

 incomplete to publish, so in my paper entitled " Notes on 

 the Marine Invertebrate Fauna of the Southern End of 

 the Isle-of-Man," which appeared in the first volume of 

 our "Fauna" in 1886, I contented myself with giving a 

 sketch of the physical features of the neighbourhood, and 

 of the special faunas of the different regions, and then 

 entered opposite the species in the list such localities as 

 '' off' Port Erin," " Shore Bay-ny-Carrickey," 4i off Spanish 

 Head," " Shorepools Kitterland," &c. That list contained 

 316 species, the number of species we now have recorded 

 from the south end of the Isle-of-Man is over 2,000. 



Since the establishment of the Biological Station at 

 Port Erin in 1893, the preparation of these distributional 

 charts has engaged our attention from time to time, and 

 several have been started but never completed. One 

 prepared by Mr. J. H. Vanstone, when Curator, has hung 

 for years on the back of the Laboratory door, and has 

 been added to from time to time. 



I have recently got Mr. Chadwick to bring together 

 the work of his predecessors and of the members of the 

 Committee, as recorded in our successive reports, and to 

 express it in graphic form on the charts. I have added 

 such additional records as I could from my own 

 experience, and Mr. Thompson, Mr. Chadwick and I have 

 carefully examined and criticised the result, as shown in 

 Plates I. -VII. I may say that although we are confident 

 of the substantial accuracy of all the records on these 

 charts, we are painfully conscious of the many omissions, 

 and of the incompleteness of the faunistic exposition. 

 However, I have come to the conclusion that the only 

 way of obtaining a more adequate record is to issue these 

 incomplete charts in the belief that they will act as a 

 stimulus, and that our students and specialists at the
