of the shell ; opaque-white within ; columella plait distinct, inner 

 lip white thinly and narrowly spread over the columella, and 

 obliterating the umbilical fissure. 



Dimensions : — Length 16, breadth 7*5, length of aperture 9-5 

 millimetres. 



Locality : — Lake Wendouree, Ballarat, Victoria. 



This species is closely related to Physa Alicia:, from which it 

 differs in its narrower and less oblique form, more attenuated 

 spire, and in the fewness of the longitudinal keels. P. Kershaivi, 

 T. -Woods, though belonging to the same natural group, is like 

 P. mcesta, Adams, of New Zealand, and therefore makes an 

 approach to P. Cumingi. 



Descriptions of Australian Micro-Lefidoptera. 

 By E. Meyrick, B.A. 



Y. TOETRICINA. 



In the present paper (together with the next instalment shortly 

 to follow) I have endeavoured to create a substantial basis for 

 the acquisition of knowledge of the Tortricina of Australia and 

 New Zealand. I have identified, classified, and redescribed the 

 species of the group indicated by "Walker in the British Museum 

 Catalogue of Lepidoptera, as well as the few others named by 

 other writers ; and have added descriptions of all the new species 

 which I possess in my own collection. In the present instalment 

 103 species are described, of which 57 are new. The worthless 

 character of Walker's descriptions is sufficiently well known ; in 

 this group, owing to the great similarity of marking and obscure 

 colouring of the species, the great majority of his descriptions 

 are in themselves absolutely unidentifiable, in the absence of 

 trustworthy generic indication. The forty species of the Tortricidce 

 which he possessed from Australia and Now Zealand are described
