308 ' DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



in tliiit of tha body; leii<>fh of the maxillary less tlian tlie leugtli of tbc Lead. Upper and 

 lower jaw with a series of roiiud pores, iiuiting at the augle of the uioutli, and continuing 

 backward over the operculum to the branchial aperture. Diameter of the orbit less than 

 the length of the snout, more than one-fifth the length of the head, and twice the width of 

 the interorbital si)ace. Origin of dorsal tin nearer to the vent than to the origin of the 

 pectorals. Ventrals short, of 3 rays, the longest slightly more than one-fourth the length 

 of the pectorals. Pectorals lanceolate, their length somewhat less than that of head. Dis 

 tance from vent to ventrals somewhat less than length of head. Scales lacking. 



Eadial formula: P. 18; V. 3. 



Color, brown above, yellowish below. 



The type, ii millimeters long, was obtained in the Hardanger Fiord, Norway, at a depth 

 of 100-150 fathoms, in September, 18G9, by Prof. Sars. The specimen was immature. 



LYCODES ZOARCHUS, Goode and Bean, u. s. (Figures 276, 276 A (youug), 283 C). 



The greatest height of the body, 40 millimeters, is about one-ninth of the total length ; 

 it is entirely covered with conspicuous imbedded scales which extend behind the dorsal and 

 anal, leaving only a narrow, naked margin around these tins. Head and pectorals naked. 

 A lateral Une begins slightly above the upper angle of the gill-opening, rapidly curving 

 downward and extending along the lower part of the body not far from the base of the anal 

 tin; it can be traced above the anterior two-thirds of the anal. 



The length of the head, 60 millimeters, is contained nearly 5| times' in the total. Its 

 greatest height, 32 millimeters, ecpials about one-half its length. The interorbital distance, 

 measured on the bone, is only one-fourth of the length of the eye. The length of the eye, 

 15 millimeters, is nearly one-fourth the length of the head and is equal to the length of 

 the snout. The nostrils are placed close to the ujjper lip and as far from each other as 

 from the eye. The maxilla reaches to the vertical through the middle of the eye. 



The length of the upper jaw, 28 millimeters, is contained 2^ times in that of the head. 

 The length of the mandible, 31 millimeters, is nearly one-half that of the head. The man- 

 dible has a consi^icuous flap on each side, about as long as the eye, beginning at a distance 

 from the symphysis equal to one-half the length of the eye. The inner edge of the man- 

 dible also has a slightly elevated ridge of skin. Length of intermaxillary series of teeth, 

 13 millimeters, equal to one-fifth of that of the head. Length of palatine series, 12 milli- 

 meters, nearly equal to that of intermaxillary. Vomerines in a round patch. IMandibular 

 teeth in three series. Width of gill opening, 25 millimeters, two-fifths length of head. The 

 ventrals are in front of the base of the pectorals ; their length, 8 millimeters, equals one- 

 eighth that of the head. The distance between the lower angles of the gill-opening, 12 mil- 

 limeters, is nearly one-fifth the length of the head. The origin of the dorsal is distant from 

 the head a space equal to one-third the length of the head; it is slightly behind the middle 

 of the i)ectoral. The pectoral when extended reaches to about the vertical from the sixth 

 dorsal ray. The longest ray of the dorsal is about one fomth the length of the head. The 

 anal orginates under the seventeenth ray of the dorsal. The vent is under the fifteenth 

 ray of the dorsal. The longest pectoral ray, 38 millimeters, is contained about 9^ times in 

 the total length. 



Color, grayish-brown, lighter on the belly and under surface of the head ; sides, ii-regu- 

 larly mottled with darker, a narrow dark edge ar the tip of the first four dorsal rays. 



In a young specimen. No. 39299, the mottliugs on the sides are band-like, the bands not 

 extending below the middle of the body entirely. This example is from N. lat. ii° 2(i', W. 

 Ion. 570 11' 15", 190 fathoms.

The type of the description is a specimen 300 millimeters long, catalogue number 39298, 

 obtained by the Albatross in N. lat. 14° 46' 30", W. Ion. 59° 55' 45", 130 fathoms, oil' Nova 

 Scotia. This species has the same number of rays in the dorsal and anal as in some 

 specimens ot L, paxillus, but the pectoral has 19 rays instead of 16, the median lateral line 

 is not developed as in paxUlus, and the form is very much stouter, the greatest height in
