is again going to Shetland on a dredging expedition with 
his friend, Mr. Jeffreys. They are to go in a steamer, and 
“ought to do good work.” How Edward envied them— 
going dry-footed, well fed, well clad, and in a steamer, while 
he was working along-shore, with no tools but his hands 
and his bag-net ! 
Mr. Norman returned from Shetland in July, and im- 
mediately recommenced his correspondence with Edward. 
“One of your shrimps,” he said, “is Caligus isonyax, new to 
our fauna, and a very interesting one it is. The male is 
as yet unknown. I hope you may succeed in meeting with 
it.” Toward the end of the year Edward forwarded a num- 
ber of species new to Britain—among others, Hurycercus 
hamellatus (obtained from the stomach of the perch), Chon- 
dracantha solex, Mysis mixta, and others. In one bottle of 
crustaceans three new species were found. The zoologists 
were evidently in ecstasies. Mr, Norman exhibited the re- 
sults of his researches at the next meeting of the British 
Association. In a letter, dated the 15th of September, 1863, 
he observed: “TI inclose a list of fifteen Moray Firth Am- 
phipoda, which you have found, and which are unknown to 
me. If you now, or at any future time, should be able to 
favor me with specimens of any of them, I shall be extreme- 
ly obliged.” The specimens were afterward sent to Mr. 
Norman. 
On the 6th of February, 1864, Mr. Bate wrote to Edward : 
“You will be glad to learn that your little specimen is Opis 
Essichtii, and that it has not been found previously in Brit- 
ain. I have reconsidered the little Hyperia, and think that 
you are right; your remarks convince me that my first opin- 
ion was the more correct. You will therefore call it Hyperia 
medusarum.” 
Mr. Bate was then publishing in parts his work on “The 
Sessile-eyed Crustacea.” He sent Edward the several parts 
as they appeared. About the beginning of 1855, Mr. Bate 
says: “You will soon get a new part of ‘ Crustacea,” and
