Albino Ringed Plover. On two occasions I saw an albino 

 Ringed Plover on the beach at Cullen. It was first seen on nth 

 October 19 16, and again about a fortnight later. It was with a 

 number of ordinary Ringed Plovers, and in size and behaviour 

 exactly resembled them. The upper plumage was very pale dove 

 colour, the rump white ; the black ring round the neck and streak at 

 the eye were present. When in flight with the rest of the flock it 

 looked quite white. J. Gowan, The Wakes, Cullen. 



Obelia gelatinosa, Pall., in the Firth of Forth. In a 



small collection of marine Zoophytes made by the late G. W. Traill, 

 the author of several excellent papers on Scottish sea-weeds, which 

 his daughter, Mrs Forrest, has kindly allowed me to inspect, there is 

 a specimen of Obelia gelatinosa, collected by Mr Traill at Joppa, near 

 Edinburgh, in 1891. The species is not in Leslie and Herdman's 

 Catalogue of Firth of Forth Invertebrates, nor has it, so far as I know, 

 been recorded since the date of that list. William Evans, 

 Edinburgh. 



Dwarf Eggs of Birds. Any species of bird seems to be 

 liable on occasion to deposit an egg very much smaller than the 

 normal size. This has generally been regarded as the first egg of 

 a young bird, but no systematic endeavour has been made on a 

 large scale to investigate the causes and nature of such dwarf eggs. 

 The blank has been filled by an important study on the dwarf eggs
