Fishes of the Western North Atlantic 349 



closer to mouth than to tip of snout by a distance about equal to diameter of eye, the 

 anterior margin slightly expanded near the inner end as an inconspicuous, broadly-tri- 

 angular lobe with rounded tip. Mouth ovate, moderately arched, its breadth 1.6 to 2 times 

 its height. Upper labial furrow only about half as long as nostril (thus shorter, rela- 

 tively, than in C. maculifinnh)-, at an angle of about 45° with the jaw. 



Teeth ^^[|~?°2i-n°oJ5 > uppers nearly symmetrical with narrow triangular cusps on 

 broad bases, with edges finely serrate on cusps and more coarsely so on bases, those toward 

 center of mouth erect, their margins nearly straight, but those along sides slightly oblique; 

 lowers with slender erect cusps, recurved slightly forward near tips, and broad bases, the 

 cusps very finely serrate, but bases less clearly so; i to 3 minute teeth at symphysis in 

 upper jaw, and i or 2 in lower; outermost 2 or 3 teeth in each jaw also very small. 



Origin of ist dorsal about over midpoint of inner margin of pectoral, its position 

 somewhat variable, its anterior margin moderately convex in small specimens but only 

 very slightly so in larger, its apex very narrowly rounded, the posterior margin nearly 

 straight toward apex but deeply concave toward base, its free rear tip noticeably slender 

 but only about Vs as long as base, its vertical height about equal to distance from corner 

 of mouth to 5th gill slit or slightly more than Y2 (62 to 64%) the length of pectoral, the 

 midpoint of its base only about V2 as far from axil of pectoral as from origin of pelvics. 

 Second dorsal between V3 and Y2 ( 3 8 to 4 1 % ) as long at base as i st, its origin over or ver}' 

 slightly behind origin of anal, its anterior margin nearly straight, its rear margin slightly 

 and evenly concave, its apex narrowly rounded or subacute, its free rear tip relatively 

 broad and only about as long as the base or slightly shorter. Caudal between V4 and Vs 

 (26 to 29%) of total length, the terminal sector between l^ and ^7-5 the length of the 

 upper margin, narrow-triangular with slightly sinuous lower contour and narrowly 

 rounded tip, the lower lobe (expanded lower anterior corner) a little less than V2 as long 

 as upper, its anterior margin moderately convex, its tip narrowly rounded or subacute, the 

 re-entrant corner (included by the two lobes) subrectangular and only slightly rounded. 

 Anal about as long at base as 2nd dorsal or a little longer, but its anterior margin some- 

 what more convex, and its rear margin much more deeply concave, its apex subacute, its 

 free rear tip slightly but definitely shorter than its base. Distance from origin of anal to tip 

 of pelvics a little shorter than base of anal. Pelvics with weakly concave distal margins, 

 their anterior margins slightly convex in small specimens but nearly straight in larger 

 ones, with bases about Yi as long as base of ist dorsal. Pectoral a little less than % (70 

 to 72%) as long as head, about V2 as broad as long but with base only about % as long as 

 outer margin, distal margin nearly straight toward tip but deeply concave toward base, 

 apex narrowly rounded and inner corner only a little more broadly so. 



Color. Dark gray, dusky bronze, or ashy blue above; pure white or yellowish white 

 below, with a more or less pronounced band of the dark upper tint extending rearward 

 along each side to about over the origin of the pelvic, including above it a forward exten- 

 sion of the pale or white of the lower side, which narrows forward. This dark band varies
