It is nearly nine years since the first . report on the 

 Medusae of the L.M.B.C. district was pubhshed by Mr. 

 J. A. Clubb (7). It contains a hst of medusae collected 

 by Prof. Herdman off the south end of the Isle of Man 

 in 1885, and by Byerley (6) and other naturalists who 

 have worked in Liverpool Bay. Most of these species I 

 have recently taken at Port Erin, some others, which I 

 have not met v/ith and w^hich are mentioned in the first 

 report, are again recorded in this report so as to make the 

 present list as complete as possible. 



My own records are chiefly based upon work done at 

 the Port Erin Biological Station between April 28th and 

 June 7th, 1893, and also between March 22nd and May 

 14th, 1894. I have confined my attention to the small 

 Hydromedusae and have not specially searched for the 

 other groups. Mr. W. I. Beaumont (5) in 1893 published 

 an account of the Lucernarians of Port Erin. I owe to 

 Mr. Beaumont my sincere thanks for the great aid which 

 he has so often generously given in helping me to collect 

 specimens of the Hydromedusae. I have not met with 

 any new species, but have added a few interesting ones 

 to the list of Manx medusae and also show that some, 

 described as species, are stages in development of other 

 species already recorded.
