D. v. 22 ; A. 19 ; P. 13-15 ; L. lat. 50-53, extending onto base 

 of caudal ; L. tr., counted obliquely backwards from origin of anal, 

 12-13-j- 1 + 3. Head 3|, height at origin of anal 4|-5| in the 

 length to the hypural. Eye equal to or a little shorter than the 

 snout, 3j-3 in the head. A band of villiform teeth in each jaw, 

 with an outer row of larger curved canines anteriorly ; a curved 

 band on the vomer, and a narrow one on each palatine. Median 

 dorsal spines longer than the others. 



r. Sandy coloured in formalin, with a broad, dark, 

 wavy band from the eye to the base of the upper caudal rays, 

 which covers the lateral line for the greater part of its length, 

 Nine grey cross-bars between the pectoral and the caudal, which 

 are most distinct below. Sides of head with some indefinite grey 

 marks ; upper lip with two dark spots, lower blackish on the 

 sides. Throat and gill-membranes with or without dark cross- 

 bars. A large dark spot on the anterior dorsal ; second dorsal

 height, and usually with a spot on the base of each ray above 

 the cross-bars on the body. Anal with a dark median band, and 

 a row of spots on the bases of the rays. Caudal dusky below, 

 with, or without indefinite cross-bauds. 



Ten specimens, 80-95 mm. long, differ from the original des-

 teeth. Dr. Steindachner has, however, kindly compared one of
