Victorian Fossils, Pi. VI. 19 



efforts the palaeozoic fossil collection of the National Museum 

 has been considerably enriched, and in whose honour the species 

 is named [1232-4]. Also from the Mines Department of Vic- 

 toria (coll. by W. H. Ferguson). [7596-7.] 



A Change in Nomenclature. 



In Part II. of New or Little-known Victorian Fossils (this 

 journal, vol. xvi., n.s. pt. 1, 1903, p. 65) the name latior was 

 proposed for a species of Lingula. This name was previously 

 given by McCoy to a Carboniferous species (Brit. Pal. Foss., 

 1855, p. 475, pi. iii., fig. 33), and therefore the above pre-occupied 

 name must lapse. The new name proposed for this fossil is 

 L. yarraensis.
