ray is much less developed, scarcely extending beyond the anterior third of the dorsal fin. 

 Middle of the anal fin strongly depressed; caudal fin subtniiu-ated ; pectoral as long as the 

 head ^vithout snout, unich shorter than the filamentous ventral fin, which, however, does 

 not reach the vent. (Giiitthcr.) 



Eadial ftmnula : B. 7; D. 5, 52; A. 4(1; V. 8; Ca-c. pyl. 10. 



Color, brownish, fins blackish, the posterior dorsal and anal rays whitish; cavities of 

 the mouth, gills, and abdomen black. (Oiinther.) 



Tills species was obtained by the ChoUoKjcr, at station 3L'0, otlthe month of the La Plata, 

 and is described and figured by Giinther (Challenger IJcport, xxii, 1887, 'J'2, pi. xix, fig. A). 



ANTIMORA, Gunther. 



Antimora, GCnthek, Ann. ami Maj;. Nat. Hist., 1878, ii, 18; Challenger Report, xxn, 93. 



Body elongate, covered with small scales. Upper part of the snout jiroduced into a 

 pointed projection. A separate caudal; 2 dorsal fins, the first with 4 or 5 rays; one anal, 

 with a deep depression along the middle. Ventrals narrow, composed of 6 rays. Jaws with 

 bands of villiform teeth; vomerine teeth in a small roundish patch; none on the palatine 

 bones. Muciferous channels on the side of the head well developed; bones of the eraniiim 

 wanting in solidity. Ventat the end of the abdominal cavity. Chin with a barbel. Brauchi- 

 ostegals 7; pseudobrauchiie none. Pyloric appendages long, in moderate number.

Antimora viola, Jordan, Cat. Fish. N. Anier., 129.— GCinther, Challenger Report, xxn, 1887, 94, pL XV. 



An Antimora Vfiih body resembling that of P/jycis, though somewhat shorter, higher, 

 and more compressed, its greatest height contained about five times in its length (without 

 caudal), its height at the ventrals slightly exceeding one-eighth of its total length, its height 

 at the middle of the caudal i)ednncle one twenty-ninth of the same. 



Scales arranged in about 115 vertical rows and about 38 horizontal ones, about 11 being 

 between the origin of the dorsal and the lateral line and about 27 below the lateral line. 

 Lateral line .slightly curved upward in the anterior fourth of its length. 



Length of head contained more than four and one-quarter times in that of the body; 

 its width half its length and less than double that of interorbltal area. 



The barbel is .short, its length being scarcely equal to half the diameter of the orbit and 

 about one-tenth the length of the head. The width of interorbltal area is about e(jual to 

 the longitudinal diameter of the orbit. In the larger s])ecimeu .slightly greater. The diameter 

 of the orbit is equal to or slightly greater than one-fourth the length of the head. The length 

 of the snout is equal to that of the operculum and less than width of interorbltal area. 



The maxillary extends to vertical from iwsterior margin of the orbit, its length about 

 equal to the greatest width of the head. Mandible equals one eighth of total length with- 

 out candal. 



Snout equal to operculum in length, obtusely pointed, much depressed, its lateral out- 

 line subconlcal, a conspicuous keel extending backward along the lower line of the orbit to 

 its posterior nuirgln. The head and mouth clo.sely resemble those of some species of Macru- 

 riis, except that the keel is covered with small, smooth .scales and is not overhanging. Ijips 

 sealeless. 



Teeth in the jaws imperfectly serial, villiform, recurved; a small oblong patch of similar 

 teeth on the head of the vomer; none on the palatines. 



First dorsal fin inserted at a distance fi'om the snout somewhat greater than twice the 

 height of the body at the ventrals; its first ray is much prolonged, its length greater than 

 that of the head, and nearly as long as or longer (in the larger specimen) than the distance 

 from the snout to the beginning of the dorsal. The second ray is contained less than four 

 times, the third six times or less In the first, the fourth about ten times. The length of the 

 base of second dorsal is somew hat more than twice the distance of its insertion from the
