58 THE VICTORIAN NATURALIST. 



Cockatoo {Cacafua sans;uinea, Gould), Western Long-billed Cock- 

 atoo {Ltcnietis pastmaior, Gould), and the Porphyrio Crowned 

 Lorikeet {Trichoglossus porphyriocephalus, Diet.), of which, so far 

 as he was aware, no scientific description was on record. He 

 then gave a somewhat lengthy criticism of " The Descriptive 

 Catalogue of the Nests and Eggs of Birds Found Breeding in 

 Australia," by A. J. North, F.L.S., Sydney, 1889, issued under the 

 direction of the trustees of the Australian Museum, Sydney, and 

 while praising the general character of the work, took the oppor- 

 tunity of pointing out a few inaccuracies and omissions, con- 

 cluding his paper by giving a brief summary of his own work 

 during the past twenty-five years, during which he had formed a 

 collection of 470 species of Australian eggs, and announcing his 

 intention of publishing shortly a complete work, entitled "The 

 Nests and Eggs of Australian Birds." 



The paper gave rise to some little discussion among the 

 oologists present. 



2. By Mr. H. T. Tisdall, F.L.S., entitled " A Species of 

 Isaria." 



In introducing the subject reference was made to three best 

 known groups of parasitic fungi — viz., EntomopthorecB, parasitic on 

 dead flies ; Lahoulbeniece, on beetles ; and Cordycejjs, to which 

 group the species of Isaria described in the paper was referred. 

 The specimen furnishing the description was discovered under 

 a piece of charred timber by Mr. H. Giles, of Nar-Nar- 

 Goon, in April last, the cocoon which constituted its home 

 being judged by Mr. C. French, F.L.S., as that belonging to the 

 Moth Dorala ocellata. Exhaustive details, supplemented by 

 illustrative diagrams and preparations for miscroscopic examina- 

 tion, enabled members to follow very clearly not only the special 

 characters of the group to which the species belongs, but also 

 furnished useful data for the identification of any other " finds " 

 in this direction. 



The paper excited considerable interest, and Messrs. E. 

 Anderson, J. Cox, C. French, C. Frost, and J. E. Prince joined 

 in the animated discussion which followed.
