p. 3845,) states that in the yeav 1800, he was engaged in the 
Hamburgh Aquarium, and obtained from New York and its 
neiglibourhood, many more King Crabs than he could accommo- 
date in that institution, or succeed in disposing of otherwise. 
Unwilling to destroy them, he conveyed them on board one of the 
London steamers, with instructions to a man on whom he could 
depend, to “throw them all overboard when the steamer got fairly 
into salt water a little on the British side of Heligoland.” This he 
had evidence was faithfully done, so there can be little reason to 
doubt that those caught off the coast of Holland are the same 
introduced by him in August, 1866, or some of their descendants. 
Milne Edwards has been recently investigating the circulating 
apparatus of Limulus, and he says that it is more perfect and com- 
plicated than that of any other known animal ; the venous blood 
circulates for a considerable distance enclosed in vessels with distinct 
walls separating them from the adjacent organs. 
Whilst regretting the few papers that have been jilaced before us 
this year, I am glad to find that the Transactions will not be less 
valuable on that account. Y^e are able to publish two very 
important additions to our Fauna and Flora of the county — viz., a 
list of Norfolk fishes, with remarks and introduction by Dr. Lowe, 
of Lynn ; and an elaborate descriptive catalogue of the Norfolk 
Lepidoptera, by Mr. Barrett. We have, I think, much reason to 
congratulate ourselves on obtaining the assistance of two gentle- 
men, whose names are a sufficient guarantee of the correctness 
of their respective lists. Mr. Barrett’s list, which is very comjDlete, 
and is published as an additional part, will, I have no doubt, 
be eagerly sought after by those interested in the study of the 
Lepidoptera, and probably induce many to visit us in the 
hope of obtaining some of the rare forms which find a habitat in 
this county. I cannot help expressing my great regret (and I am 
sure yours also,) that Mr. Barrett will no longer' be able to give us 
his valuable assistance as heretofore ; in losing him the Society has 
lost a member who cannot soon be replaced. I must also 
congratulate this society on the publication (b}’^ permission of the 
Meteorological Society,) for the first time in our Transactions, of
