 crustaceans including Nectocarcinus integrifrons, M.-Edw., from 

 Port Jackson, Cancer novce-zelandice, Jacq. & Lucas, from New 

 Zealand, Lithodes mala, Leach, from Norway, and Macrophthal- 

 mus setosus, M.-Edw., one specimen of the last of these being- 

 distorted by the attack of a parasite (Bopyrns sp.). 



Mr Froggatt exhibited a series of co-types of the parasitic 

 Hymenoptera described in Mr. Ashmead's paper. 



Mr. Waterhouse exhibited the sexes of the butterfly commonly 

 known as Papilio Erectheus, Don.; and he raised the question of 

 the authority for the choice of names in this and similar cases. 

 The female was originally described and figured by Donovan in 

 the " Insects of New Holland" (1805) as P. JSgeus (pi. xiv.), and 

 the male as P. Erectheus in the same work (pi. xv.). 



Mr. Greig Smith illustrated the technique of the double stain- 

 ing of spores and bacilli proposed in his paper; and he also 

 showed mounted preparations under the microscope. 



Mr. Steel exhibited a fine series of volcanic bombs from Auck- 

 land, N.Z.

 Mr. J. H. Maiden, exhibited pot plants of Selaginella involvens, 

 Spring., (in cultivation usually known as S. circinatus, Presl.) from 

 the Philippine Islands, and Oncidium carthaginense, Swartz
