28 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



and backward. Supraocular ridge elevated, not sharp, finely granular, with 

 preocular and postocular spines. Ridges and spines on head as in J. emmelane, 

 but none of the former roiigh-serrate. Eye large, 3J in head, longer than snout 

 and more than twice the interorbital width. Mouth little overpassed by the 

 rostral spines, the maxillary reaching slightly behind front of orbit, 3^ in 

 head. Teeth present on jaws, vomer and palatine. Barbels fewer than in A. 

 emmelane. Three are present on maxillary, two of which are at its posterior 

 end, the upper much the longer. The third is inserted more anteriorly, behind 

 the middle of the maxillary. Eight shorter barbels are present on each man- 

 dibular ramus, the posterior only near the joint. Several short baibels on gular 

 region, and a cross series on branchiostegal membranes, usually one barbel for 

 each ray. Plates on the body as in A. emmelane, all with sharp spines, which 

 are present, though small in the ventral series. Middle of breast with one 

 median and two lateral series of plates, all of which bear distinct longitudinal 

 keels. The two lateral ridges on breast are the anterior continuation of the 

 ventral ridges of the trunk. 



The spinous dorsal begins at the seventh dorsal plate, the last dorsal spine 

 articulating with the thirteenth plate. The first and last rays of the second 

 dorsal articulate, respectively, with the eigliteenth and twenty-fourth plates- 

 The dorsal series unite at the thirtieth plates, the median series of nine plates 

 thus formed bearing double or bifid spines throughout. The first and the last 

 anal rays articulate, respectively, with the sixteenth and twenty-third plates 

 of ventral series (excluding the anterior three on breast). The ventral series 

 coalesce immediately opposite the union of dorsal series. The anus is opposite 

 the interspace between the third and fourth plates. Ventral spines long and 

 slender, equaling length of snout and eye. Pectorals equaling length of head in 

 advance of opercular joint. Five lower pectoral rays with incised membranes, 

 the tips projecting. 



Color similar to A. emmelane, the back and sides with 7 or 8 narrow black 

 crossbars, the posterior of which extend faintly on the under surface. The inter- 

 spaces on back are somewhat dusky, with lighter vermiculating lines and spots, 

 a few of which extend on the bars. The dorsals have a speckled appearance, 

 and are darker above the black dorsal bars. Head blackish above, the liead and 

 body light or slightly dusky below. Ventrals white. Anal white, with some 

 black markings along the base of the rays. Pectorals with a wide black bar at 

 base, succeeded by a wide white bar, followed by a narrower black bar and 

 a narrow terminal white bar. Caudal with a narrow basal bar of black, then a 

 narrow white bar followed by a broad black bar, and edged with white.
