breadth of their markings, and in their colouration. The indi- 

 vidual variation, in specimens of either of these races, is very 

 slight. In Northern New South Wales and South Queensland 

 occur two other races, very different from the typical form, differ- 

 ing from one another only in degree, and also showing slight 

 individual variation. At Port Macquarie, a fifth race occurs; 

 this exhibits remarkable variation. Specimens caught during 

 October, 191.3, showed every gradation between the Northern 

 New South Wales race, and that occurring in the south. The 

 transition from one race to the other, is not a gradual one, for 

 the characters of either race may be combined, in every possible 

 way, in individual specimens. It is suggested that 7'isiphone 

 originally was confined to the Main Dividing Range, and became 

 differentiated into two distinct forms concomitantly with the 

 changes which gave rise to the low drier area through which the 

 Hunter River flows. Subsequently, the species were able to 

 reach the coast, and, at Port Macquarie, we have the result of 

 the refusion. — Mr. Waterhouse also exhibited two historically 

 interesting examples of butterflies caught in the Eastern Archi- 

 pelago, by the late Alfred Russell Wallace. 



Mr. E. Cheel exhibited and contributed notes on a series of 

 interesting grasses, comprising Vulpia My uros Gmel., Syn. Festuca 

 Myuros L., spelt "Myurus" by several authors, (Rat's-tail Grass); 

 and V. ciliata Link, Syn. F. ciliata Pers., (Ciliated Rat's-tail 

 Grass). Both species are from Centennial Park, and Government 

 Domains, Sydney; and there are also specimens in the National 

 Herbarium from South Australia, and from several localities in 

 West Australia. They have been mixed up with V. bromoides 

 S. F. Gray [Festuca bromoides L.), but are more common than 

 the latter. — Avena barbataBrot., (Slender Oat-Grass); Centennial 

 Park(E. Cheel; November, 1899), and Government Domain (No- 

 vember, 1912). For two additional localities, see These Pro- 

 ceedings, 1912, p.653; and Victorian Naturalist, 1913, p.85, for 

 previous records. — Cynosurus echinatus L., Cock's-comb Grass);
