XXVI. Exrracrs from the Minute-Book of the LINNEAN 
Society of LONDON. 
June 7, Ow the retirement of Alexander MacLeay, Esq., F.R.S, 
1825. 
&c. from the office of Secretary of the Society, the 
following Minute, recommended by the Council, was 
adopted by the General Meeting of the above date, viz: 
«' The Linnean Society of London take the earliest 
opportunity, after the retirement of Alexander Mac- 
Leay, Esq. from the Secretaryship of the Society, to 
record upon their Minutes the high estimation in which 
he is held by them, on account of twenty-seven years of 
unremitted and unrequited labour devoted to science ; 
and that in quitting, for a time, this sphere of usefulness, 
to fill an honourable station in a distant country, he 
carries with him the cordial esteem and sincere regret 
. of this Society.” 
Read a Letter from Mr. Charles Willcox, accom- 
panied by Specimens of Mytilus bidens, found by him 
adhering to the bottom of His Majesty's ship Wellesley, 
which had nine years before arrived from India, but 
had not from that time quitted Portsmouth harbour. 
The species appears to propagate itself readily : and 
. it seems very probable that it has become naturalized 
in the harbour, Mr. Willcox having found large masses 
of them.
