Hedley, C— The Range of riacostylus. Proc. Linn. Soc. N.S.W., vii., pp. 335-39. 

 The distribution of Placostylus is New Caledonia, 34 species; Solomon Isle, 16 ; 

 New Hebrides, 3; Fiji, 16; New Zealand, 1 ; Lord Howe Isle, 1. The conclusions 

 of the author are (1) the Archipelagoes of Solomon, Fiji, New Hebrides, Loyalty, 

 New Caledonia, Norfolk Isle (?), Lord Howe, and New Zealand form one 

 province to be called the Melanesian Plateau ; (2) this plateau derived its fauna 

 from Papua via New Britain and not from Australia ; (3) New Zealand and New 

 Caledonia were early separated from the northern Archipelagoes ; (4) the Fijis 

 remained to a later date in connection with the Solomons.

Dr. Scharff having received genuine specimens of the P. riparius, Westr. , 

 finds that what he previously alluded to (Irish Nat., 1892, i., p. 192) as being 

 referable to this species are but large specimens of P. crista, v. nantileus.
