Diayn. — The high dorsal fin, having 17 rings before it, stand- 

 ing on 9, of which 4 belong to the body, and supported by 

 34 or 35 rays, has a brownish colour with about nine obhque 

 whitish bars. 



Descr. — This species comes near to Acus, but is easily distin- 

 guished from it by the diagnosis. It shows twelve or thirteen dark, 

 or darkly marbled, cross-bands on the body and tail, on a lighter 

 ground-colour. The snout is shorter, being no longer than the 

 distance between the proximal border of the orbit and the distal 

 edge of the gill-cover. The back is thinner and more concave.

 of its head 0*67 inch; length of head and body 2'17 inches; of

 the pectoral fin. Head and snout together either a little

 fin stands. The dorsal is based on 10 rings, and there are 

 from 18 to 20 rings before it.

 Its length is 7" 12 inches. Length of its head 0"91 inch ; of its 

 snout - 51 inch; of the body, measured from the edge of the 

 pectoral ring to the vent, 2 - 17 inches; of the dorsal fin - 95
