634 NOTES AND EXHIBITS. 



form, taken from Fulmarus glacialis, was described, in 1885, by 

 Piaget as Ancistrona gigas. Kellogg has taken an Ancistro7ia 

 from several petrels, which he has referred to A. gigas Piaget. 

 Recently Dr. Harvey Johnston and Mr. Harrison received an 

 Ancistrona from Pelagodroma marina from the Kermadec Islands; 

 and in a paper before the New Zealand Institute, now in the 

 press, expressed the opinion that only one species of Ancistrona is 

 so far known, and that it must be called A . procellarice Westwood. 

 The present material, collected from the same host as Westwood 's 

 type, substantiates this opinion; as it is undoubtedly identical 

 with the form described by Piaget as A. gigas. 



Archdeacon Haviland exhibited a so-called Mulga-ball, com- 

 posed of the impacted, indigestible, fibrous matter of the twigs of 

 the Mulga {Acacia aneura F.v.M.), from the intestine of a sheep. 

 Also an egg of a Mallee-Hen {Lipoa ocellata Gould), which he 

 had taken from a mound-nest in the Cobar district. 



Mr. E. J. Bickford showed a flowering specimen of Niiytsia 

 Horihunda R.Br.,[]Sr.O. Loranthace^] the Christmas Tree of 

 West Australia. 



Mr. Cheel, on behalf of Mr. Maiden, communicated the fol- 

 lowing Note: — "At the Meeting of the Society on September" 

 27th, Mr. F. Turner exhibited a "Blue Couch "(/'amcwm didac- 

 tylum Kunth), "which is said to have caused the deaths of a 

 number of pasture animals near Muswellbrook, Upper Hunter, 

 N.S.W., in 1907, as reported in the papers." I enquired into the 

 matter at the time, examined and took specimens of the suspected 

 grass in various localities, but on no occasion was the above- 

 mentioned grass shown to me as suspected. I determined the 

 grass as the common Couch {Cynodori dactylon L. C. Rich.), but 

 it now turns out to be the closely allied Cynodon incompletus 

 Nees, a South African or East African grass, according to Dr. 

 Stapf of Kew, which I now exhibit and record, for the first time, 

 as introduced into Australia (Muswellbrook, N.S.W.). I also 

 show detailed drawings, and point out that the most obvious 

 difference between the two species is " rhachilla produced " in
