18 very short and aduate to the body for the whole of its length. Lower 

 rays of pectoral tins prodnced, extending beyond the meml>rane, the 

 longest extending beyond the upper ray of the fin ; anal longer and lower 

 than soft dorsal, ending at the same corresponding place, last ray reach- 

 ing to the fifteenth plate before caudal fin; ventral differing in length in 

 the diflerent sexes; vent anterior, situated on the tenth plate in front of 

 anal. Color dai'k brown, belly white; sides crossed with irregular white 

 bars, giving the fish a mottled appearance ; snout black ; a black streak 

 along lower edge of preopercle; a Itlaok spot on iris above; dorsals light, 

 mottled with black; anal white, with dark mottlings, a dark bar across 

 the posterior rays, the tips of all the rays white; ventrals black, abruptly 

 white at tips; pectoral and caudal dark, with a white border, a light spot 

 in the center of fins and many white spots on the rays; a black spot at 

 base of pectoral. Paget Sound ; known from 2 specimens, collected with a 

 seine near Point Orchard, the largest 7 inches in length. (Jordan & 

 Starks); another since taken at Port Ludlow, {kv, in; /.leXdvrj, ink,

Head 4f in length; eye 3^^ in head, width at base of pectorals 7; depth 

 8J. D. VII, 8; A. 9; P. 12 on each side; 39 plates in dorsolateral series. 

 Very closely related to A. emmclanc, with which it agrees in coloration and 

 general appearance as well as in most details of structure. It differs in 

 the following resjiects: The snout is shorter, the rostral spines scarcely 

 protruding lieyond the piemaxillaries. No barbels on snout below rostral 

 spines, oi' on margin of preorbital, or at mandibular joint. Region between 

 rostral spine and front of premaxillaries wholly occupied by a triangular 

 movable plate, with rough granular surface; breast with 3 parallel series 

 of sharply keeled plates; no spine at posterior end of premaxillary fossa; 

 ventrals very long and slender, wholly white; spinous dorsal, anal, and 

 pectorals with fewer rays; rostral projection shorter than in A. cmmelane, 

 with 2 short forwardly directed spines, behind which is a pair more 

 widely separated directed downward and backward; supraocular ridge 

 elevated, not sharp, finely granular, with preocular and postocular spines ; 

 ridges and spines on head as in A. emmelanc, but none of the former 

 rough serrate. Eye large, longer than snout and more than twice tha 

 interorbital Avidth. 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. evimdanc; 

 3 present on maxillary, 2 of which are at its posterior end, the upper 

 much the longer; the third inserted more anteriorly behind the middle 

 of the maxillary; 8 shorter barbels are present on each mandilmlar 

 ramus, the posterior only near the joint; several short barbels on gular 

 region, and a cross series on each brauchiostegal membrane, usually 1 

 barbel for each ray. Plates on body as in A. emmclanc, all with sharp
