British Museum (Natural History). (8vo, London, 1892) J 
Prof. F. Jeffrey Bell called attention to two books which had been 
received from the Trustees of the British Museum. The first of these 
was an account of the zoological collections made during the voyage of 
H.M.S. ‘ Alert,’ and the other was the catalogue of British Echinoderms 
already mentioned in the Society’s Journal ; this contained, amongst 
others, six plates, illustrating the spicules of all the species of Holo- 
thurians found in the British seas. 
The President said that though these volumes might be regarded as 
a species of exchange, the rules of the Museum required that they 
should be sent as a present from the Trustees to the Society, so that it 
would no doubt be the pleasure of the meeting to return a special vote 
of thanks for this valuable donation. 
Prof. Bell said that the Council had, owing to the uncertainty as to the 
unfortunate fate of Prof. Hermann Fol, taken no steps up to that time
