XXVI. Extracts from the Minute-Book of the Linnean 



SociETv of London. 



June 7, On the retirement of Alexander MacLeay, Esq., F.R.S., 

 18'25. &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 naturalised 

 in the harbour, IMr. Willcox having found large masses 

 of them.
