to white on the belly. Four longitudinal 

 rows of dark brown spots on the body and 

 blotches on the body and fins distinguish this 

 fish from other closely related species. The 

 dorsal, as well as the two pectoral fins, con- 

 tain one sharp strong spine outside of the 

 usual number of soft rays. In the aqua- 

 rium this fish thrives well, if the water is 

 kept moderately warm. 



The Common or Longjawed Catfish (A1111- 

 iirus vulgaris), is as interesting a fish as it is 

 hardy and modest in its requirements. The 

 color is of the darkest olive brown, almost 

 black on the back, and, passing gradually 

 through different shades, changes to a much 

 lighter color on the belly. Its eyes are en- 

 livened by a circle of the brightest gold color. 

 It has two long barbels on the upper, and 

 four shorter on the lower lip. While the 

 catfish is fond of hiding among dense veg- 

 etation, it will often, and for hours at a time, 

 venture out of its shelter and indulge in 

 lively play and graceful sport.
