Colour : The top of the head and back brownish-purple ; 

 cheeks, sides, and part of the belly silvery, with golden re- 

 flections ; the lower part of the belly pure white. The ex- 

 terior surface of the pectorals when closed are covered with a 

 silvery integument almost up to its tip, this being caused by 

 the external portions of the rays being so covered ; when 

 spread the intervening membrane is very dark-brown. The 

 whole of the interior surface of the pectorals is uniformly a 

 very dark brown, almost black. Ventral fins uniform dark- 

 brown, almost black. Dorsal and anal fins immaculate. 

 Upper and lower limbs of caudal brown, central portion im- 

 maculate. 



The pectoral fins of specuhger have " an oblique white 

 band across its lower half" and " a broad whitish edge," whilst 

 its " ventrals are white, the middle rays greyish."
