jaw, rather large, pointed, slightly recurved, close-set, in a single row. 

 (An examination with a binocular microscope after the preserving 

 liquid was removed with filter paper showed no trace of smaller teeth 

 behind the outer row, and they are most probably not present. 

 There is a possibihty that minute teeth are embedded in the thick 

 mucous membrane, but this could not be determined more definitely 

 without injury to the specimen.) Teeth in lower jaw smaller than in 

 upper, subequal, in a narrow band, about four rows at symphysis, 

 tapering off to a single row at angle of mouth, the band interrupted 

 at symphysis by a narrow bare space. Tongue with a wide truncate 

 margin in front, not emarginate. Three short fleshy flaps on shoulder 

 girdle. Anal papilla broad, subquadrate, and rather flat in preserved 

 specimen, its distal margin finely fimbriate, in appearance similar to 

 that of females of Awaous. The two dorsal fins well separated, none 

 of the spines of the first dorsal notably filamentous, not reaching 

 origin of second dorsal when laid back. Origin of anal slightly 

 behind that of second dorsal, both fins ending on nearly the same 

 vertical, their posterior rays not reaching base of caudal when laid 

 back; 11 rays in both fins (the first unbranched ray included and the 

 last two which are approximate at their base being counted as one) . 

 Ventral ends well in advance of vent. Bases and tips of ventral and 

 pectoral nearly on same verticals. Caudal fin not prolonged. 



The cutaneous papillae and mucous canals may be described as 

 follows, in so far as they be observed by a microscopic examination 

 without treating the specimen with special reagents : 5 transverse rows 

 under eye, the first one rather oblique, the others more or less vertical, 

 the last one incomplete; 2 longitudinal rows on cheek, the upper at 

 about middle of cheek extending from fourth transverse row to mar- 

 gin of preopercle, the lower extending from first to fourth transverse 

 rows, anteriorly curving along outline of upper lip, posteriorly hori- 

 zontal; a broadly curving row of papillae along angle of preopercle 

 extending below to articulation of mandible and continued with some 

 interruption along inner edge of lower jaw; 2 transverse rows on 

 opercle, one near either margin, connected by a horizontal row not far 

 from lower margin ; a transverse row directly behind eyes, continued 

 horizontally backward at level of middle of eye, to base of pectoral; 

 a broadly V-shaped row forward from upper to lower nostril and 

 backward to upper lip ; a short lengthwise row connecting lower end 

 of latter with middle of first transverse row under eye; a short row 

 on inner side of upper nostril parallel to upper profile; a horizontal 

 mucous canal along upper edge of opercle to middle of eye, thence 

 curving along upper edge of eye to a conspicuous pore located at about 

 end of anterior third of eye, where what appears like a short cross 

 mucous channel connects the two from the opposite sides; mucous 

 channels on snout not easily followed without special treatment; a 

 transverse mucous canal along vertical edge of preopercle.
