Fishes of the Western North Atlantic 223 



First dorsal fin: vertical height 3.2; length of base 7.0. 

 Second dorsal fin: vertical height 3.3 ; length of base 6.9. 

 Anal fin: vertical height 4.35 length of base 13.9. 

 Caudal fin: upper margin 25.0. 



Pectoral fin: outer margin 10.6; inner margin 6.4; distal margin 5.1. 

 Distance from snout to: ist dorsal 49.5; 2nd dorsal 62.5; upper caudal 75.O; pec- 

 toral 24.75 pelvics 43.3; anal 56.6. 



Interspace between: ist and 2nd dorsals 8.2; 2nd dorsal and caudal about 3; anal 

 and caudal 0.0. 

 Distance from origin to origin of: pectoral and pelvics 19.6; pelvics and anal 12.5. 



Trunk slender, highest opposite axil of pectoral, tapering evenly rearward, its 

 height at axil of pectoral (where highest) about Vr its length to origin of caudal. Body 

 sector to cloaca a little longer than tail sector. Dermal denticles with 3 ridges and 3 teeth, 

 as in riveri, but with the teeth shorter and overlapping more, so that the skin is more con- 

 cealed. 



Head about Vi of total length, flattened above, and contracted laterally just anterior 

 to outer ends of nostrils. Snout broadly rounded, its length in front of mouth a little more 

 than Vs as great as length of head to origin of pectoral, with a median belt of conspicuous 

 mucous pores in 8 or 9 irregular rows on its ventral surface. Eye oval, its horizontal diame- 

 ter about % as great as distance between nostrils, its midpoint opposite corner of mouth. 

 Spiracle oval, its diameter about Yz as great as that of eye, and behind latter by a distance 

 about % as great as diameter of eye. Gill openings much smaller relatively than in riveri, 

 the 1st to 3rd (longest) a little less than V2 as long as distance between nostrils, or about 

 % as long as horizontal diameter of eye, the 5th (shortest) about % as long as ist, of the 

 same general type as in riveri (p. 227), their anterior outlines so deeply concave that the 

 tips of the gill filaments are exposed on all 5 of the interbranchial septa; the 4th and 5th 

 over origin of pectoral. Nostrils moderately oblique, at margins of head, their outer ends 

 about equidistant between tip of snout and center of mouth, the distance between them a 

 little less than Y-y as great as length of snout in front of mouth, the anterior margins more 

 broadly rounded than in riveri (the condition of the specimen is not good enough for de- 

 scription of the inward cirroid extensions of the nostril, if any). Mouth ovate, nearly 3 

 times as broad as high. Labial furrows very prominent, the upper extending about V2 the 

 distance toward the symphysis, and more nearly parallel with the jaw than in riveri, the 

 lower a little shorter than the upper. 



Teeth about ||^; uppers with long, sharp median cusp, flanked on either side by 

 2 or 3 smaller cusps; lowers similar to uppers, except with the lateral cusps somewhat 

 larger relative to the median cusp, and more often 3 in number on one or both sides; no 

 median tooth in either jaw; several series functional. 



Dorsals similar in form, brush-shaped, with rounded tips and weakly convex anterior 

 margins. Origin of ist about over midpoint of bases of pelvics, its base a little less than %
