6 THE AUSTRALIAN ' NATURALIST. 
EGG OF THE LARGE-BILLED BLACK COCKATOO. 
To the Editor. 
Dear Sir,—In August last I received from Mr. Edwin 
Ashby, of Adelaide, an egg of the large-billed black cockatoo 
(Calyptorhynchus macrorhynchus), from Cape Ford, N.T., 
which he stated was apparently undescribed. I exhibited it 
as such at the September meeting of the Club. In making 
the digest of the minutes for the October NATuRALIsT, the 
qualification was accidentally omitted, and it appeared as the 
‘“‘undescribed egg.’’ I was not in a position to state that 
it was undescribed, as I had taken no steps to verify Mr. 
Ashby’s note. 
Immediately on publication of the journal I received a 
note from Mr. Dudley Le Souéf, C.M.Z.S., stating that he 
had described the egg of this species in The Victorian 
Naturalist, Vol. X1X., page 91, and that the type was in 
Mr. H. L. White’s Belltrees collection. I subsequently saw 
Mr. White, and explained the matter to him. He told me 
he had written you on the subject, and requested me to ask 
you to withhold his letter from publication.—Yours, etc.,

REPORTS OF EXCURSIONS. 
Visit to LANE Cove River. 
Octoper.—At the invitation of Mr. A. J. Vogan, 
F.R.G.S., the excursion of the club was held at 
Mt. Mars, Lane Cove River. The members were met at the 
Bridge, Lane Cove River, by Mr. Vogan, who took the party 
for a delightful trip up the too little known upper waters of 
the Lane Cove. The party was afterwards landed near Mt. 
Mars, and entertained by Mr. Vogan at afternoon tea. After 
tea some of the party, headed by Mr. Vogan and Mr. Gurney, 
started across country collecting specimens en route, and 
eventually struck the tram at Gore Hill. Some good beetles 
and specimens of the bush flora then in flower were collected. 
Insects were not plentiful, everything being rather late this 
season. Mr. Vogan’s kindness and hospitality were highly 
appreciated by the members. ;
