VAIM0SA Jordan & Seale. new genus. 

 Vaimosa Jordan & Seale, new genus of Gobiidse ( V. fontinalis).

 covered with large scales. The species inhabit mountain brooks of the South Sea Islands. The type 

 is Vaimosa fontinalis, from the Gasegase stream at Vaimosa in Upolu. Gobius javanicus Bleeker prob- 

 ably belongs to the same genus.
