Precision measurements were made on the holotype and a paratype, 

 and these are expressed in thousandths of the standard length, 

 respectively. Standard lengths 165 and 305 mm. Length of head 

 340 and 338; greatest depth 340 and 318; length of snout 139 and 161 ; 

 diameter of eye 64 and 54; fleshy interorbital space 121 and 115; 

 postorbital length of head 155 and 154; least preorbital width 75 

 and 75; least depth of caudal peduncle 155 and 144; length of caudal 

 peduncle 182 and 165. Length of longest dorsal spine 109 and 105; 

 of soft dorsal ray 127 and 128; of anal spine 67 and 65; of soft anal ray 

 115 and 125; of pectoral 230 and 226; of pelvic 182 and 177; of caudal 

 255 and 236. 



The following counts were recorded for holotype and all paratypes: 

 Dorsal IX,10; anal 111,9, pectoral ii,12, pelvics 1,5, branched caudal 

 rays 6 + 5. Additional counts are recorded in table 4. 



Lips do not cover the whitish teeth; angle between upper and lower 

 lips varies from 35 to 55 degrees; the inner upper lip joins the outer 

 upper lip about equidistant between corner of mouth and symphysis; a 

 canine tooth present on largest specimen at inner corner of upper jaw, 

 but canines are absent on smaller specimens; distal margin of caudal 

 fin slightly concave on smallest specimens, with outer rays a little 

 elongate in larger ones. 



In alcohol the background coloration is light grayish to light brown ; 

 a dark brown streak along center of each scale row, beginning with 

 lateral line row, and continuing to belly, these prominent dark streaks 

 separated by prominent pale streaks, both extending from behind 

 head to caudal peduncle, latter paler than rest of body; median fins 

 light brown; dorsal and anal fins narrowly edged with dusky; paired 

 fins pale, dorsal rays of pectoral dusky; usually some of the scales 

 under the appressed pectoral fin have a dark bar anteriorly. Some 

 dusky or brownish streaks occur around mouth as illustrated in figure 

 20 (see p. 46). The lengthwise streaks on the largest specimen, 305 

 mm., have largely changed into a solid dark brown below lateral line, 

 and the back, as in the smaller specimens, is light gray; caudal pe- 

 duncle and caudal fin light gray or very light brown; scales on lower 

 sides behind pectoral bases blackish anteriorly, pale posteriorly ;'^fins 

 not edged with dusky. 



A specimen 46 mm. long has 7 black spots basally on dorsal fin and 

 3 black spots basally on anal fin; dorsal edge of caudal peduncle with 

 2 black dots, ventral edge with a pair of dots; a black spot each at 

 dorsal edge and ventral edge of caudal fin base; pelvic fin with 2 black 

 bars; at a standard length of 86 mm. these color marks have almost 

 disappeared, but at a length of 67 mm. the peduncular region is white 

 or pale and dorsal fin barred. 



The following notes on the color when alive were made from a
