FISHES FROM BERING SEA AND KAMCHATKA. 



47 



Mouth smaller than in other species, but little oblique, the maxillary not reaching vertical from 

 middle of orbit. Anterior series of premaxillary teeth slightly enlarged, as are also a few of the anterior 

 mandibular teeth near symphysis; vomerine teeth in a single curved series; palatines with an ellip- 

 tical patch. Upper preopercular spine long, only moderately hooked, placed low, its tip well below 

 the level of upper pectoral ray, its posterior margin extending beyond edge of opercle; in the smallest 

 of the cotypes, a slight prominence can be detected on inner side of hook, corresponding to the den- 

 ticle in Coitiiisculus: in one specimen, a strong straight spine is present on each preopercle above 

 the hooked spine, its direction parallel with the preopercular margin, directed do^vnwards and back- 

 wards; lower preopercular spine small, directed do^vn wards and fonvards, the margin of the bone 

 above it with 2 rotuided prominences. ^ 



Nasal spines small, often concealed beneath thick integument. Occipital region depressed, gently 

 concave, without trace of ridges or prominences. Maxillarj' barbel simple, slender. Occipital filament 

 minute; all others obsolete, or represented by inconspicuous tubercles; none present on preopercle or on: 

 sides of body above base of pectoral. Pores on mandible and preorbital comparatively small ; anterior 

 mandibular pair distinct and widely separated, though obliquely facing each other. A pair of pores 

 on anterior part of interorbital space, a median pore on middle of space, and i behind orbits, the latter 

 forming the apex of a A-shaped row on occiput. Gill membranes with a free margin mesially, the 

 width variable, about three-fourths diameter of the pupil in the type. 



Dorsal fins contiguous in males, usually well separated in females. Spinous dorsal elevated in 

 males, the fin when declined reaching base of fourth or fifth ray of second dorsal; the membranes of 

 the first 4 or 5 spines incised, but for less than half their height. Last anal ray slightly behind last 

 dorsal ray, the anal fin longer than soft dorsal. Ventrals longer in males, but failing to reach the vent. 

 The lower 14 or 15 pectoral rays simple, the branched rays the longest. 



Color in spirits: Above brownish, everywhere with narrow sometimes reticulating lighter lines, 

 and small light spots; 4 ratlier indistinct darker bars; i on occiput, i below middle of spinous dorsal, i 

 below posterior half of soft dorsal, and i on caudal peduncle; the bars more or less invaded by lighter 

 reticulating lines and small spots. Branchiostegal membranes dusky in males, pale in females, the 

 lower parts generally colorless. Spinous dorsal in the male usually with large roundish brown spots, 

 which are often irregular in size and arrangement, and maybe so placed as to form lengthwise streaks; 

 soft dorsal with 5 oblique dark bars; caudal with 3 or 4 dark crossbars, usually wider than the inter- 

 spaces, often concave on distal side; anal unmarked; ventrals somewhat dusky in males, unmarked in 

 females; pectorals with a large round white or yellowish white spot on basal portion of the middle rays, 

 the upper rays with faint dusky crossbars, the lower blackish with white tips in males, colorless in 

 females; in males, tlie ventrals and the lower part of pectorals are sometimes dusted sparsely with fine 

 black specks. There is often a broad light V-shaped bar behind occiput, and sometimes in addition a 

 broad light crossbar under end of soft dorsal. Sometimes in males these marks arc bright white, as may 

 be also an irregular spot on opercle and i or 2 on lateral line. 



Numerous specimens were obtained at the following stations off Avatcha Bay, Kamchatka: 



List of Stations. 



Artediellus miacanthus, new species. (Fig. 7.) 



Type, a male specimen, 66 mm. long, from station 4795, off the east coast of Kamchatka (latitude 

 52° 46' 50" N.); depth 48 to 69 fathoms. 



Resembling Artediellus pacijicus, but differing in color, in the fewer pores of the lateral line, the 

 obsolete nasal spines, and the simple maxillary barbel.
