DISCUSSION OF SPECIES AND THEIR DISTRIHUTION. 375 



'2&J-M, U. S. N. M., from station S!»l, in 39° 40' N. lat., 71o 10' W. Ion., at a, depth of 480(?) 

 fathoms. A single specimen, taken from tlie stomach of a Chiasmodon niger,was received 

 from Gloucester in 18.80.

This species is readily distinguished by the peculiarly i>roduce(l snout, which forms a 

 short, triangular, pointed lamina, .sharply keeled on the sides, and overhanging the cleft 

 of the mouth. * 



The head is rather short, broad posteriorly, half as long as the distance between ventral 

 and anal fins. Eye round, rather large, its diameter one-fourth of the length of the head, 

 less than that of the snout, and nearly equal to the width of the Hat intenn-bital space. 

 Month wide, the maxillary extending nearly to below tlie hind margin of the eye. Teeth 

 in both jaws in narrow villiform bands; a small group of teeth on the vomer. Posterior 

 extremity of the maxillary not much dilated. Nostrils close together; the posterior are 

 wide, semicircular ojieiiings, the anterior narrower and round. The vent is rather nearer 

 to the end of the o])erculum than to the root of the caudal. 



The entire head (even the gill membrane and the foremost part of the snout) and the 

 body are covered Mith small cycloid scales, of which only a few have been preserved; there 

 are about 10 in a transverse line between llie first dorsal fin and the hiteral line and 1-40 in 

 the lateral line. 



The greater part of the dorsal and anal fins are covered with scales. The first dorsal 

 is subcontinuous with the second, and the first ray is produced into a filiiment about as 

 long as the head. The second dorsal and anal fins are rather low; the latter so much 

 depressed in the middle as to present the appearance of a double anal. The fiee portion 

 of the tail is narrow, terminating in a comparatively small caudal fin, which is truncated 

 behind. Pectoral pointed, the upper rays being the longest; it is as long as or longer than 

 the head exclusive of the snout. The two outer ventral rays prolonged as two filaments; 

 the second being twice as long as the first, and not extending as far back as the pectoral. 



Radial formula: D. 4, 51-50; A. 38-39; Y. 0. 



Color, black; the cavity of the mouth, gills and abdomen deep black. 



This form occurs midway between the Cape of Good Hope and Kerguelen Island, and 

 also east of the mouth of the Rio de la Plata. The ChaUeiH/er obtained a specimen, 12i 

 inches long, at station 14(J, near Marion Island in 1,375 tathoms; and a specimen 24 inches 

 long, at station 320, ott' Montevideo, in 600 fathoms. 



HALARGYREUS, Gunther. 



HularinjrniK, GdNTnER, Cat. Fish. Brit. Miis., iv, 1802, 312. (type, H. Joknsonii, Giintlior.) 



Body elongate,- covered with small scales (a separate caudal); 2 dorsal and 2 anal 

 fins, the latter subcontinuous; veiitrals composed of several rays. Jaws with a band of 

 minute villifi)rm teeth of efpial size; no teeth on the vomer or palatine bones. No barbel. 

 Branchiostegals 7. Pseudobranchiic glanduliir, rndimentary, covered by the membrane; 

 gill rakers of the outer branchial arch long. (Gilntlicr.) 



HALARGYREUS BREVIPES, A'aillant. (Fig. 325.) 



EaXargijreus brevipin, VaillaNT, Exp. Sci. TiMvailleur ct Talisman, xxil, 1888, 295, pi. XXV, fig. 5. 



A Ualarfiyrens having (accordiiig to Yaillant), a general resemblance to Merluvi us smi- 

 ridus, body being nearly cylindrical anteriorly, and its thickness nearly equal to its 

 greatest height, which is one eighth of its length. The length of the head is one-fourth the 

 length of the bodj^, and its width is a little less than its height. Snout moderate, its length 

 about one- third that of the head. Mouth rather large, although the maxillary does not 

 extend beyond the vertical from the center of the orbit. Lower jaw slightly longer than
