388 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



No. 28857, U. S. N. M., lioin station 949, in 40° 03' N. lat., 70^ 31' W. Ion., at a <lei)tli ol" 100 

 fathoms; also by the Speedwell from station 238, in 42° 30' 30" N.lat., 70'= 3S' W. Ion., at a 

 depth of 43 fathoms; and from station 214, ofl'Cape Ann, Mass., in 57 fathoms.

As mijjht have been predicted from the discovery among the American si>ccies, tliat 

 of Europe lias been found to occur at considerable depths southward. The Travailleur took 

 it at 306 meters in the Gulf of Gascony in 1880 (station xvii), and the Talhrnun off the 

 coast of Soudan in 640 meters (station Lxiii), as well as in 99-118 meters, along the coast 

 of Spain, and by Vincigueri-a, at 600 fathoms in the Gulf of Genoa.

Bregmacerotidv, Gili,, Arr. Faiu. Fish., 1872, 3, (No. 22); Proc. Acad. Nat. Sci., Phila., 1881, 173; Century 

 Dictionary, I, 1889, 675. 



Gadoids having a robust caudal portion, truncate or convex behind, almost without pro- 

 current caudal rays above or below; an antemedian anus; moderate suborbitals; terminal 

 mouth; jugular ventrals abnormally developed; an occipital ray; a continuous dorsal tin, 

 mostly confined to the caudal portion, and an anal nearly similar to the long dorsal. {Gill). 



BREGMACEROS, Thompson.

 CalloptiJum, RiCHAKDSON, Voyage of the Sulphur, Fishes, 94. 



Body fusiform, compressed posteriorly, covered with cycloid scales of moderate size. 

 Two dorsal tins; the anterior reduced to a single long ray on the occiput; the second and 

 the anal much depressed in the middle, nearly divided into two; ventrals very long, com- 

 posed of 5 rays, the outer of which are very elongate. Minute movable teeth round the 

 margin of the mouth and on the vomer; none on the ijalatines. No air bladder; no pyloric 

 appendages. Gill openings very wide, the gill membranes being united below the throat, 

 not attacliedto the isthmus. Pseudobranchiic none; 7 branchiostegals. {Gihither.) 



The type species, B. MacelcUandii, Thompson, is known from the China seas, the Pacific 

 near the Philipiiines, and the Indian Ocean. This genus has recently been added to the 

 Atlantic fauna in the form of a well-marked species. 



Alcock obtained numerous young specimens of a species of Bregmaceros in the Lacca- 

 dive Sea, in 95 fathoms (Alcock, Ann. and Mag. Nat. Hist., July, 1891, 29).

The species agree very closely with B. Macclellandii, Thompson, from which, however, 

 it differs in the lesser number of rays in the first anal, and in the greater height of the 

 vertical fins (judging from figures). 



The type (cv) is 46 millimeters long to base of caudal. Form compressed, moderately 

 elongate. Body height (6 millimeters) 7g in its length. Interorbital area conve.v-, its widt h 

 (2i nullimeters) greater than diameter of eye (2 millimeters), which is 4 in length of head 

 (8 millimeters). Length of head 5} in total. Jaws even in front. 



Maxilla reaches to vertical through middle of eye; the mandible to vertical through 

 Ijostcrior margin of eye. 



Teeth on intermaxillary minute, apparently in a single series; mandibulary teeth 

 biserial, the inner teeth enlarged. 



Scales large, about 10 in a transverse series, about 65 in a longitudinal series.
