Lejridorhombus megastonia, Dcmov. — Megrim or Sail Fluke. 



The pelagic eggs of the megrim or sail fluke occur 

 frequently outside Port Erin Bay, but are only captured 

 irregularly inside the breakwater. They first made their 

 appearance in 1914 in a haul taken in the Bay on 

 March 21st, and again on the 30th. The eggs were 

 present in nearly every haul taken at the observation 

 stations outside the Bay from April 1st to 20th. In one 

 of those hauls from outside the Bay it was estimated that 

 there were 494 megrim eggs. They were generally 

 distributed in the central area of the Irish Sea throughout 

 the month of April. The following table gives the 

 distribution of megrim eggs off the South-West of the 

 [ale of Man in tbe plankton collected in 1914: —
