4.3 in length; in adult specimens the width of the large thick 

 head equal to or greater than its depth behind eyes, its length 

 3.1 to 3.3 in head and trunk together ; the boldly convex snout 

 bluntly rounded, 2.6 to 3.4 in head; the oblique eyes very high 

 up but lateral, and equal to or 0.8 of length of snout ; the eyes 

 very close together, the interorbital space 3 to 4 times in 

 length of eye; the mouth low down, moderately oblique, rather 

 small, the lower jaw rather weak and equal to upper jaw or 

 sometimes barely projecting beyond it, the posterior angle of 

 maxillary beneath front margin of eye; there are four rows of 

 teeth in upper jaw, those of outer row enlarged, widely spaced, 

 the others very small ; the lower jaw has five rows, the outer one 

 short with enlarged teeth and a small lateral canine hardly 

 larger than the rest at its posterior extremity; the remaining 

 four rows all of very small teeth; the body covered with firm 

 ctenoid scales which become much smaller between pectoral and 

 first dorsal ; the entire head and nape naked back to first dorsal, 

 or there may be a few very small cycloid scales above opercle, 

 forward almost to eyes, with a few scattered scales just in front 

 of first dorsal; a double row of papillae crosses middle of prs- 

 opercle from front to back, with other rows above and below 

 more or less developed; there is a large open pore at anterior 

 extremity of interorbital space; the supraopercular groove 

 prominent; at its origin behind eye is a large pore, with one or 

 two pores behind it ; on posterior margin of preopercle are three 

 large pores ; the base of pectoral and breast covered with small 

 cycloid scales; the first dorsal rather low, a little less than f 

 depth of body, the tips of first four spines greatly elongated and 

 threadlike, longer than head and extending to base of fifth or 

 sixth ray when depressed; the second dorsal about as high as 

 first dorsal, the anal a little lower ; both second dorsal and anal 

 have elongated ray tips, their posterior rays longest, the fins 

 sharply angulate posteriorly, usually not reaching caudal when 

 depressed; the pectoral round pointed, of moderate size, its 

 length nearly equal to depth ; the ventrals are broad and do not 

 reach anus ; the depth of caudal peduncle approximately 0.75 its 

 length; the round-pointed caudal shorter than head, 3.6 to 3.8 

 times in length; the anal papilla small, slender and pointed in 

 males, subglobose in females.
