DISCUSSIOK OF SPECIES AND THEIR DISTRIBUTION. ."»7T> 



26220, I . S. N. ME., from station 891, in 39° 16' N. lat., 71 LO' W. Ion., al a depth of 480( .', 

 fathoms. A single specimen, taken from the stomach of a Ghiasmodon niger,wa,$ received 

 from Gloucester in L880. 



ANTTMOR V ROSTRATA, Gt nther.

This species is readily distinguished by the peculiarly produced s t. 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 tins. Bye 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 interorbital space. 

 Mouth wide-, the maxillary extending nearly to belo^ the hind margin of the eye. Teeth 

 in both jaws in narrow villifonn hands; a small group of teeth on the vomer. Posterior 

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

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

 to the end of the operculum t han 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 with small cycloid scales, of which only a few have been preserved : there 

 are about 10 in a transverse line between the first dorsal tin and the lateral line and 140 in 

 the lateral line. 



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

 is subcontinuous with the second, and the firs! ray is produced into a filament about as 

 long as the head. The second dorsal and anal fins are rather low 7 ; the latter so much 

 depressed in the middle as to present the appearance of a double anal. The free 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 Kergnelen Island, and 

 also east of the mouth of the Rio de la Plata. The Challenger obtained a specimen, 12A 

 inches long, at station 140, near Marion Island in 1,375 fathoms; and a specimen 2A inches 

 long, at station 320, off Montevideo, in 600 fathoms. 



HALARGYREUS, Guuther. 



Balargyrem, GOnther, Cat. Fish, Brit. Has., iv, 1862, 312. (type, //". Johnsonii, Gtlnther.) 



Body elongate, covered with small scales (a separate caudal): L' dorsal and 2 anal 

 tins, the latter subcontinuous: ventrals composed of several rays, .laws with a baud of 

 minute villifonn teeth of equal size; no teeth on the vomer or palatine bones. No barbel. 

 Branchiostegals 7. Pseudobranchise glandular, rudimentary, covered by tin- membrane; 

 gill rakers of the outer branchial arch long, ((liuilhcr.) 



HALARGYREUS BREVIPES, Vaili.ant. (Fig. 325.) 



Balargyreus brevipes, Yaii.i.ant. Exp. Sci. Travailleur el Talisman, xxn, 1888, 295, pi. xxv, tig. 5. 



A Halargyreus having (according to Vaillant), a general resemblance to Merlucius smi- 



ridux, 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 body, and its width is a little less t han 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 thi' center of the orbit. Lower jaw slightly longer than
