Dr. Chapman exhibited an album of photographs showing 

 the embryonic development of Botys hyalinalis, and taken by 

 Messrs. Hammond and Jeffreys. It consisted of five or six 

 series of photographs taken at short intervals, showing the 

 gradual changes in the development of the larva within the 

 ovum. They were exceedingly well developed, and showed 

 the smallest details very clearly, thus forming a unique 

 record of embryonic growth from the moment of exclusion 

 of the ovum until the hatching of the larva. This species 

 is peculiarly adapted to such observation, as its egg is very 

 flat and possesses an unusually transparent shell. 



Mr. E. Step exhibited specimens of Helvetia crispa, Ft., 

 and Clavaria coralloides, L., from Ashtead, and remarked 

 that all the Helvellce appear to be rare in the neighbour- 

 hood of London, though Cooke records several from Epping 

 Forest. He said : " On October 17th H. crispa was really 

 plentiful at the foot of the chalk downs, and I could have 

 gathered several pounds of it. Cooke describes it as only 

 occurring one or two at the time — at most half a dozen — and 

 gives the impression that it makes a dish gre Xly to be 

 desired. Worthington Smith, however, says they have 

 little flavour and are very tough. I should say they have 

 too much flavour — an earthy one, like spinach, — but I did 

 not find them actually tough. I should imagine that the 

 taste for them has to be cultivated, and I regard them as 

 better to look at than to eat." 



Mr. Step also exhibited photos of the above species, and 

 of Lycoperdon gemmatnm, Mendius anrantiacus, Hygrophorus 

 virgineiis, Tricholoma nndus, Triclioloma terreus, and Pleurotus 

 ostreatus. 



Mr. R. Adkin read the Reports of the Field Meetings at 

 Limpsfield (see page 14) and St. Paul's Cray (see page 20). 



Mr. W. J. Kaye exhibited specimens of Theope endocia, T. 

 foliorum, and Nymphidimn lysinwn, with figures of the larvae 

 and pupae from Trinidad. All these were found to live on 

 friendly terms with species of ants, and the ants milked the 

 larvae above the anal segment. The two first species feed on 

 cocoa, and the last on Cassia sp.
