beaches north and south of the Heads, from Deewhy to Bondi. 

 On the 24th instant, Dr. Cleland collected twelve specimens, 

 which were, with two exceptions, in an advanced stage of de- 

 composition. They were all of the one species which breeds 

 on the Islands in Bass Strait, and on the Victorian coast; they 

 were extremely emaciated, and three examples sexed were 

 females. Numerous instances of mortality amongst these birds 

 are on record, and various theories have been advanced as to 

 the cause — storm, waterspout, epidemic disease, and conflict with 

 the species breeding along the coast of N.S.W., but I suggest 

 that there is little doubt that the cause is starvation. The birds 

 having followed a food supply northwards, and the failure of 

 this supply, has resulted in the death of the birds. In 1911 I 

 noted and examined numerous dead and dying specimens of this 

 species at Ulladulla, X.S.YV. 



Mr. J. J. Fletcher showed examples of leafy galls on Cas- 

 sinia sp., caused by a fly (Trypeta sp.), and some teratological 

 developments, not understood, on Aster ramulosa and Kennedya 

 monophylla.
