The gills of the air-breathing estuarine goby, <I>Pseudapocryptes lanceolatus</I>, are reduced owing to the development of a specialized organ of O<SUB>2</SUB> uptake from air. In the first gill arch, the filaments of the outer hemibranch are reduced to nearly one-half in comparison to those of its inner hemibranch. A smaller number of secondary lamellae per mm (27.6) occurring on one side of the gill filament reduces the gill surface area. A bilogarithmic plot of the gill area and the body weight indicates a curve with two significantly different components, one (<I>b</I>=0.924) related to the fish weighing up to 6g and the other (<I>b</I>=0.405) to the fish weighing 8g and above.
