402 DEKP-SEA FISHES OF THE ATLANTIC BASIN. 



seventh ray of flic anal, and at a distance from the first dorsal (20 millimeters) about equal 

 to the, diameter of the eye. The longest rays are not as long as the barbel. It contains at 

 least 110 rays. The anal is inserted under the interspace between the two dorsals; its 

 height is equal to one-fourth the length of the head. It contains at least 110 rays. The 

 l)ectoral is inserted in advauce of the origin of the first dorsal, its length (33 millimeters) 

 half that of the head. Its tip extends to the vertical from the fifth anal ray, and to about 

 the seventeenth S(;ale of the lateral line. The ventral originates under the second spine of 

 the dorsal, its outer ray somewhat produced, extending slightly beyond the origin of the 

 anal. The distance of the vent from the origin of the ventral e(iuals the length of the eye. 



Color, silvery gray, with yellowish and lavender tints. 



Many specimens were obtained by the Albatross. The type is selected from a number 

 obtained at station 2377, in the northern i)art of the Gulf of Mexico, 29'= 07' 30" N. lat., 88° 

 08' W. Ion., at a depth of 210 fathoms. Its length is 200 millimeters. Others were obtained 

 from station 2143, in 9° 30' 45" N. lat., 76° 25' 30" W., Ion., at a depth of 155 fathoms; from 

 station 2400, in 28° 41' N. lat., 8(P 07' W. Ion., at a depth of 169 fathoms; and from station 

 2401, in 280 33' 30" N. lat., 85° .52' 30" W. Ion., at a depth of 142 fathoms. 



CCELORHYNCHUS FASCIATUS, (Gunther), Goodk aiul Bkan.

Fig. A. 



Sncmt not much produced, shorter than the eye, which is very large, two-fifths of the 

 length of the head, its vertical diameter being considerably more than the width of the in- 

 terorbital space. Scales with from 8 to 10 subparallel keels. Upper and lateral portions 

 of the head covered with small I'ough scales, lower naked. There are four scales in a trans- 

 verse series between the first dorsal spine and lateral line; distance between the two dor- 

 sal fins equal to the length of the base of the first. Anterior dorsal spine smooth. Outer 

 ventral ray produced into a filament. Distance between the vent anil isthmus shorter than 

 the head without suout. Barbel small. Whitish, with broad, irregular, blackish bands 

 across the back. 



Radial formula: I). 12; A. 62; r. 15; V. 7. {Gihither.) 



The Challenger obtained it from stations 305A, 309, 309A, and 311, on the east coast of 

 the southern extremity of South America, at depths of 125, 40, 140, and 245 fathoms, resiiec- 

 tively. 



The species is closely allied to Macrurus australis, but has (1) a narrower forehead, 

 (2) a larger eye, and (3) fewer keels on the scales. In the smaller and younger specimens 

 the keels are fewer in number (5 to 6) and have a more divergent direction than in the larg- 

 est example.

 Corypliwnoidea (as subgenus), Gunther, Challenger Report, xxii, 1887, 124. 



A genus -with general characters of Macrurus, but with teeth in villiform bands above 

 and below, imbricate and spinigerous scales, mouth wide and lateral ; snout short, oblique, 

 truncated; barbel very small; anterior dorsal spine finely barbed ; outer ventral ray filamen- 

 tous.
