distinctly stating that his nomen 7ioviiniis proposed "in exchange 

 for Cuvier's generic name," it is evident that Phricus must sink 

 into a synonym of our fish for which Castelnau's prior genus 

 PseufJaphritis will henceforth stand, leaving without a generic 

 name the neantarctic porosut^, if indeed it should prove to be a 

 good species and not, as is most probable, an immature form of 

 Eleg inops viaclovinus. 



Some months ago I received, through the kindness of Mr. 

 Arthur Wilson, of Geelong, three fine specimens of a Pseud- 

 aphritis from the fresh waters of Victoria, whei'e it is known to 

 anglers as the '' Tupong,"* and having also in my possession two 

 examples of the Tasmanian fish, sent to me by Mr. Morton, I was 

 enabled to institute a comparison between the insular and conti- 

 nental forms, and at the same time correct my generic and specific 

 diagnoses; the result of this comparison leads me to believe that 

 there is but one species common to the fresh waters of Tasmania 

 and south-eastern Australia, the correct title of which is I'seud- 

 aphritis urvillii. 



It now only remains to find a generic name for the Aphritis 

 gohio of Giinther, all the other species associated under that genus 

 by the author of the British Museum Catalogue having been 

 provided with suitable names. So far I have been unable to 

 ascertain that any generic name has as yet been proposed for this 

 fish, and, following my usual custom under such circumstances, I 

 refrain from designating it, not having access to an example on 

 which to base a diagnosis; to those, therefore, who are more for- 

 tunately situated than I — Dr. Giinther for preference — the task 

 of suggesting an appropriate name is left. 



I append, however, a brief analysis of the three, probably 

 monotypic, genera, which have at various times been associated 

 under the inadmissable title Aphritis, giving as far as is possible 

 a full generic along with a partial specific synonymy.
