that under the dorsals the body is 8-hedral; dorsal and ventral faces 

 t,a-ooved, and depth equaling- length. Caudal peduncle stronoly 

 depi-essed, nearly -t-hedral (median dorsal and ventral ridj^-es extremely 

 low); 40 or 50 plates in the dorsal series, 4 or 5 pairs l)etween dorsals, 

 IH or 14 pairs from ventrals to anal; 3 or 4 laroe plates in a median 

 lonoitudinal row on breast, with al)out 1 row of 4 or 5 small ones 

 between it and the series forming- the edge of breast; plates radially 

 striated and a little elevated at the center; none between ventrals and 

 vent. Branchiostegal meml)rane naked posteriorly, li or ;■> plates 

 anterolaterally. Narrow nude surface of lower jaw with a series of 

 several jDlates; 2 or 3 plates in front of pectoral. Head verv long and 

 narrow, gentlv tapering, nearly as high as wide. Orbits nearly circu- 

 lar, the longitudinal diameter 5i^ to t> in head and 2^ in snout. Inter- 

 orbital space moderately concave, nearl}' 2 in orbit. Supraocular ridges 

 moderate, occipital ridges scarcely defined, temporal ridges moderate, 

 all spineless; no suborbital ridge; suborbital bone spineless; a sharp 

 spine at posterior angle of preopercle and 2 smaller flat ones below; a 

 longitudinal series of 4 or .5 poorly developed plates on lower part of 

 cheek, between the long horizontal limb of preopercle and orbit. 



Fig. 7.— Fallasina barbata. 



Snout long, tubular, about 2i in head. Frontal bones much elongated 

 forward, an additional bony plate in front of preorbital and overhang- 

 ing- the maxillary; several small plates in membranaceous interval 

 between preorbital and frontal in front of orbit. Posterior inferior 

 angle of maxillary produced backward, reaching a little more than 

 halfway to orbit. Median rostral plate absent. Lower jaw long, 

 curved upward in front, projecting beyond the upper and entering 

 profile; mouth oblique. Teeth in narrow bands on jaws and vomer, 

 about 1 row on palatines. A single barbel of variable length in speci- 

 mens from Nemuro; it is little developed, shorter than eye; in those 

 from Aomori, at its longest; it is longer than head at tip of lower jaw. 

 Gill membranes united behind, free from isthmus. First dorsal with 

 12 to 14 pairs of plates between it and the occiput; anal long, begin- 

 ning under middle of first dorsal; pectorals long. 5i to in l)ody. 

 width at their base about 4 in their length; ventrals about 3 in pecto- 

 rals and 4 in head in female, 2 in pectorals and 2f in head in male. 

 Color reddish or grayish brown with innumerable minute black points; 

 ventral surface pale, from front of anal to caudal progressively darker 

 with minute black spots; a dark band extends along the side' of snout, 

 across orbit and preopercle; anterior dorsal dusky, darker behind;
