Notes to the Above, by C. Hedley. 



In detailing the catalogues relating to the Land and Freshwater 

 Shells of New Zealand, there was omitted on p. 614 mention of 

 Hutton's "List of the Freshwater Shells of New Zealand" 

 P.L.S.N.S.W. (1) vii. pp. 67-68. Another list, then unknown to 

 me, by Ancey, enumerating and classifying the Helicoids of New 

 Caledonia, Bull. Soc. Mai. France, v. p. 357, should have been 

 named on p. 616. 



Mr. Pilsbry informs me that Realia appeared in the Synop. 

 Contents B. M. 1840, p. 153, without any sort of description. 

 The name should, therefore, date from 1850. 



With reference to sp. 23, T note that Gould himself says, Otia 

 Conchologica, p. 224, of his own species, lateralis, that it " is L. 

 neritoides, Gray, probably." 



E. R. S [ykes] writes (Conchologist, Sept., 1893, Vol. ii. p. 180) : 

 " The Zoological Society informs me that the part in which 

 Pfeiffer's original description appeared was issued in March or 

 April, 1854, though bearing the date 1852. There is, therefore, 

 no question as to priority, and Pfeiffer's names must be given up 

 for Reeve's." Therefore, as I conjectured, the names PfeifFer 

 attached to species 54, 59, 62, 65, 66, 72, 90, 94, 96, 99, 108, 111, 

 117, 131, 145, 147, 158, 164, 166, 167, 168 and 169 first appeared 

 in the Monographia Heliceorum Viventium, Vol. iii., and should 

 be dated 1853, the date of that Volume.
