Sal, Darling River near Wilcannia {E. G. Vickery). Nepean 

 Eiver {Lesson). 



This is about one of the commonest Eresh Water bivalves we 

 have, it is found in nearly every river and small stream in New

Notes on the Zoology of Lord Howe's Island. 



By E. p. Eamsay, F.L.S., Curator of the Australian 



Museum. 



The Zoology of Lord Howe's Island has always been looked 

 upon with considerable interest by Naturalists. The fauna

 some of our early Naturalists was drawn to this Island by finding 

 there, the now extinct "White Gallinule," then called (i^eJ^V^

 of this bird will be found in Herr von Pelzeln's Paper, in the 

 " Ibis " 1871, p. 44 ; where its relation to the genus JVofortiis was 

 first pointed out, a good figure of it also will be found, in the 

 **Ibis," 1873, pi. X.

 heard or seen of them. The only other largo land bird known,
