to fourth pairs forming gently converging lines, the fourth pair at 

 the sides of vent and a little anterior to it; first interspace shortest, 

 the third longest. Supraanals angulated, the upper in contact with 

 the lateral line, vertically above base of first anal ray, the middle 

 pair above the vent or slightly behind it, about midway between 

 lateral line and lower profile, the anterior pair horizontally in front 

 of middle pair, or a trifle lower, just in advance of vertical from third 

 ventral pair. Anteroanals 8, the last pair elevated, in fine joining 

 the seventh and the posterolateral, halfway between the two or a 

 trifle nearer the seventh pair; all but the eighth pair, form a high 

 arch with its concavity toward the anal base, the first pair much 

 nearer anal base than the second, the third still farther diverging, 

 the remaining pairs again gradually approximating anal base, the 

 seventh pair over the fifth before last anal ray. Posterolateral in 

 contact with lateral fine. Posteroanals 7 or 8. Precaudals 4, the 

 lower 3 forming a direct continuation of the anal series, there being 

 sometimes a short interruption but frequently none; the intervals 

 between the precaudals usually shorter than those of the anal series, 

 the three forming an arch at base of the lower caudal lobe, the third 

 noticeably elevated; last precaudal on the lateral line. A patch of 

 3 overlapping luminous scales on back of caudal peduncle and 4 to 

 7 below. 



Several specimens, ranging in length from 63 to 190 mm., were 

 obtained with the trawl at the following stations:
