March 27th, 1912.

 Monthly Meeting (29th November, 1911). amounting to 31 Vols., 

 248 Parts or Nos., 60 Bulletins, 1 1 Reports, 37 Pamphlets, and 

 one Map, received from 108 Societies, ikc, and three Individuals,

NOTES AND EXHIBITS. 



Mr. D. G. Stead showed some remarkable examples of early 

 developmental stages and well-formed fry (alevins), with the yolk- 

 sac partly absorbed, of the large Salmon Catfish, Galeichthys 

 thalassinus (Riippell). These had been taken during February 

 from the mouths of two adult male fishes, each about 3 feet in 

 length, at Ulmarra, Clarence River. Although these fishes were 

 known previously to incubate their eggs orally, it had not been 

 demonstrated whether the male only did the work, as in some 

 other species, but Mr. Stead's investigations showed that this was 

 also the case in both Galeichthys australis and G. thalassinus. 



Mr. Basset Hull exhibited a skin and an e^s. of the Allied 

 Petrel {Puffinus assimilis Gould) taken on the largest of the 

 Admiralty or Roach Islands, Lord Howe Island. The egg was 

 taken on the 28th September, a late date for this species, which 

 breeds on Norfolk Island in July. This is the first recorded 

 instance of the species breeding on the Lord Howe Group. Eggs 

 of the Fleshy-footed Petrel {Puffinus carneipes Gould) taken at 

 Lord Howe Island, on 9th December, were also shown. These 

 eggs display remarkable vaiiation in dimensions. 



Mr. Fred Turner again exhibited a specimen of the grass 

 Panicum glabrum Gaud., (syn. Paspalum ambiguum DC.) pre- 

 viously exhibited at the Society's Meeting in May, 1911, and sub- 

 sequently forwarded to Kew Gardens for authoritative decision; 

 and he communicated a letter from Dr. 0. Stapf, Keeper of the 

 Herbarium, confirming his determination of the species. A 

 specimen of the grass had been presented to the Society's herba- 

 rium, and was available for inspection.
