1) In the list of fishes collected by Semon (Max Weber in Semon, Zool. For- 

 schungsreise Australien etc. V. 1895, p. 268) one of us named also Amphisile 

 scutata (L.) horn. Thursday Island. A. R. Mc Culloch (Biol. Results "Endeavour" 

 III. 191 5, p. 105) has quoted this statement under the synonyms of Centriscus 

 cristatus de Vis, without having seen the specimen. The distinguished australian 

 ichthyologist was probably under the impression that a specimen of Centriscus 

 from Thursday Island must belong to the australian species C. cristatus de Vis. 

 This is an error, the Thursday Island-specimen is Centriscus scutatus L, Never- 

 theless we thought it advisable to enlist C. cristatus de Vis as it is not impro- 

 bable that this species will be found along the south coast of New Guinea.
