CHAP. xv. NEW CRUSTACEA FOUND. 323 



Upon further investigation, Edward came to the 

 conclusion that the Hyperia is no more the parasite of 

 the Medusa, because it is sometimes found upon it, 

 than a crow is the parasite of a tree because it some- 

 times lights upon it. As Edward's name was now 

 frequently quoted in matters of Zoology, he thought 

 that it might be of some use to give the results of his 

 observations to the world on the subject. Hence the 

 appearance of his " Stray Notes on some of the 

 Smaller Crustaceans," which shortly after appeared 

 in the Journal of the Linnean Society.* 



It is probable that the facts in that paper, as stated 

 by Edward, had some influence on the minds of Pro- 

 fessor Westwood and Mr. Spence Bate ; as Hyperia 

 medusarum does not appear in their list of Sessile- 

 eyed Crustacea, the last part of which was published 

 at the end of 1868. 



To give an idea of the indefatigable industry of 

 Edward in his researches among the Crustaceans, it 

 may be mentioned, that of 294 found in the Moray 

 Firth, not fewer than twenty-six new species were 

 added by Edward himself!
