have previously only been known as inhabitants of the float-

The Rey. Mr. Norman also communicated with Edward 
about the same time, and informed him “that the atylus is 
not a parasitical species, though there are some crustacea 
(Hyperia) which are parasitical upon Medusa.” 
Upon further investigation, Edward came to the conclu- 
sion 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 sometimes 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 Professor 
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 mention- 
ed, that of 294 found in the Moray Firth, not fewer than 
twenty-siz new species were added by Edward himself!
