NOTES AND EXHIBITS. 287 



tributed over the whole shell. Of variety A one specimen 

 {exhibited) was found in a nest together with a heavily blotched 

 normal egg; another was found with two normal eggs, and the 

 clutch of three (exhibited) was forwarded from Montague Island a 

 little later in the season. Of variety Bl the first specimen (exhi- 

 bited) was found alone in a nest surrounded by dozens of other 

 nests, all of which contained normal eggs. Of variety B2 a pair 

 was found in a nest in the centre of the largest group of nests in 

 the rookery; and a pair (exhibited) was shortly after forwarded 

 from the Island. Such striking departures from the normal colour 

 had not previously been recorded by any of the Australian 

 authorities; but Mr. Tom Iredale, of Christchurch, had met 

 with a blue mutation in the eggs of Larus ridihmdus, L. 

 fuscus, and L. argentatus, collected in the North of England, 

 in 1889-90; and also in the eggs of L. dominicanus and Sterna 

 frontalis in New Zealand. 



Mr. Cheel exhibited a series of specimens illustrating the 

 habits and depredations of a leaf-cutting bee (Megachile sp.), 

 and of two pollen-collecting bees (Podalirius cingidatus Fabr., 

 and Sarapoda bombiformis Smith). The contents of a nest 

 in the ground, comprising a good handful of oblong or roundish 

 pieces of the foliage of Laburnum vulgare collected by the 

 Megachile were shown, and also a branch of Solarium xantho- 

 earpum from a plant which used to fruit freely, but which in 

 recent years had borne no fruit, apparently through being 

 deprived of pollen by the operationsof the pollen-collecting bees. 

 For the identification of the insects, Mr. Cheel expressed his 

 indebtedness to Mr. W. J. Rainbow, F.L.S., of the Australian 

 Museum. 



Mr. Goddard exhibited an interesting series of freshwater 

 crustaceans, including species of Anaspides and Phreatoicus> 

 from ponds on Mount Wellington and Mount Ben Lomond, 

 Tasmania; and examples of freshwater leeches (Glossiphonia) 

 from Tasmania and New South Wales.
