D. 79. A. 60. 



The height of the body is rather less than one-third of the entire 

 length, the length of the head two-ninths, and that of the caudal two- 

 thirteenths. Snout with the lower jaw prominent, equal in length 

 to the diameter of the eye, which is nearly one-fifth of that of the 

 head; maxillaiy as long as the eye. The upper jaw with a series 

 of twenty-eight smaU truncated teeth on the blind side, those of the 

 other side being few in number and very small. Eyes separated by 

 a verj^ narrow, naked, bony ridge. Scales small, but conspicuous ; 

 lateral line with a very slight curve above the pectoral ; a second 

 series of pores commences above the eye, and follows the dorsal pro- 

 file to the twenty-sixth dorsal ray, where it terminates. Dorsal and 

 anal rays quite smooth ; the dorsal commences above the anterior 

 third of the orbit, and terminates at a distance from the caudal 

 nearly equal to the depth of the free portion of the tail. Ajial spine 

 prominent. The longest dorsal rays are somewhat behind the middle 

 of the fin, rather shorter than the pectoral, and half as long as the 

 head. Uniform brownish.

The height of the body is somewhat more than onc-haLf of the total 

 length (with the caudal), the length of the head one-fourth, and that 

 of the caudal one-fifth. The interorbital space is exceedingly narrow 

 and raised, ridge-Uke ; snout very blunt and short, mouth small, 

 with the jaws even. The dorsal commences above the anterior part 

 of the orbit, and terminates at a short distance from the caudal ; 

 its longest rays are on and behind the middle of the fin. Scales 

 very smaU, cycloid. The lateral line is slightly arched above the 

 pectoral ; a similar scries of pores runs from the upper eye, along 

 the base of the dorsal fin, to about the middle of the length ; there 

 is a connecting branch between both lines across the occipital 

 region. Greyish, densely dotted -with black and spotted with white.
