NOTES AND EXHIBITS. 



Mr. Hedley exhibited living specimens of Panda atomaia. 

 Gray, drawing attention to the marked difference in sculpture 

 between the embryonic and adult shells, a feature of much 

 importance from a systematic standpoint. Also living specimens, 

 lately procured from Scone by Dr. Cox, of an Helicarion presumed 

 to be leucospira* Pfeifier, a long lost species which has not been 

 heard of since it was originally described in 1856 as coming from 

 " Australia ": a specimen of Cystopelta petterdi, collected by Mr. 

 J. D. Cox, at Mt. Wilson, the most northerly locality from which 

 this mollusc has yet been obtained : and examples of Helicarion 

 thomsoni, Ancey, received from Dr. Thomson of New Bedford, 

 U.S.A., and collected at Geographe Bay, West Australia, by an 

 American whaler, this novelty being interesting as the first of the 

 genus known from that colony. 



Mr. Brazier exhibited typical specimens, received from the 

 author, of Dijylomorpha delatouri, Hartman, and he contrasted 

 them with a new member of this genus, of which he showed 

 specimens, from Siegond Island, Santo Espiritu, New Hebrides : 

 also examples of Piiipa fallax from New Bedford, U.S.A., its 

 distinctness from the Australian P. pacifica, Pfr., with which 

 some writers have confounded it, being pointed out. 



Mr. Maiden showed a collection of interesting plants from the 

 Richmond River, and kindly intimated that they might be added 

 to the Society's herbarium. 



Mr. Trebeck exhibited a specimen of a flying fish, DactylopterxLS 

 orientalis, from Port Jackson. 



* Mr. Smith, after kindly comparing these specimens with the types in 

 the British Museum, confirms this identification. The Scone examples 

 are, he says, but half the size of the types ; they are also half the size of 

 specimens which I have seen from the Richmond River, collected by 

 Messrs. Petterd and Helms. C, H., 20th July, 1892.
