DISCUSSION OF SPFX'IES AND THEIR DISTRUiUTlON. 69 



directly Opposite the anal, which it resembles in shape and size. Caudal peduncle short and 

 slender. Ventrals absent. Pectorals broad and short, placed low. Caudal small, weak, 

 probably eniargmate or tnincate. Lateral line broad, consistinj^' of two furrows connected 

 vertically by numerous short cross grooves. 



CETOMIMUS GILLII, Goor>E and Hean, ii. s. (Figure 78.) 



The height of the body is a little less than one-fourth of the total length; length of 

 head a little less than one-third. Eye minute; contained about 2.3 times in length of head, 

 and about 8 times in that of snout; inserted midway between the inargin ofthe jawand the 

 dorsal profile, distant fiom the former a space contained about 2.\ times in the length ofthe 

 snout. The maxillary reaches very far back, extending to a point behind the orbit equal to 

 li times the length ofthe snout. The origin of the dorsal is directly above that of the anal, 

 which is inserted a short distance behind the vent; distance from the snout equal to more 

 than 4: times the length of its own base, and the distance of its termination from the root 

 of the upi)er rays of the caudal equal to its own greatest height. The anal fin is .similar in 

 shape and extent to the dorsal, but has the thirteenth to the fifteenth rays the longest, 

 while the eighth to the eleventh are the longest in the dorsal. The length of these longest 

 rays is about equal in the two fins, and is contained slightly less than 3 times in the 

 lengthof the head. The pectoral fin is inserted somewhat below the middle ofthe body 

 and close to the extremity ofthe opercular flap. It is broadly lanceolate, and its length is 

 contained about 3J times in that of the head. Ventrals lackin g. Color, blue-black. The 

 lateral line sweeps in a bold curve from a point above the upper angle ofthe gill opening 

 to a point in th(^ middle of the body between the origin ofthe dorsal and anal fins, and 

 thence in a straight median line to the base of the caudal.

A single specimen (jSTo. 3.5029, U. S. N. M.), 5 inches in length, was taken by the Alha- 

 trosn, August 20, 1884, at station 220G, in 39° 35' N. hit., Tio 2-4' 30" W. Ion. at the depth of 

 1,043 fathoms. 



CETOMIMUS STORERI, Goode and Bean, n. s. (Figure 79.) 



The height of the body is a little more than one-fourth of the total length; the length 

 of the head is contained 3^ in that of the body. Diameter of the eye contained about 18 

 times in the length of the head, and about 7 times in that of the snout, the eye being inserted 

 nearer to the dorsal profile than to the jaw, its position in the vertical being twice as far 

 from the line ofthe upper jaw as from the dorsal line; it is nearly in the line ofthe vertical 

 erected from the middle of the upper jaw to the right angles of its edge. The lower jaw is 

 strongly curved, and projects far beyond the upper. The origin of the dorsal fin is a little 

 in advance of that ofthe anal, which is inserted at a distance from the vent equal to 3 or 4 

 times the diameter of the eye. The dorsal flu is longer than the anal, the termination of 

 the latter being under the fifth ray from the end t)f the dorsal. They are about eijual in height, 

 and the direction ofthe rays when erected is backward and at an acute angle with the axis 

 of the body. The longest rays are contained about 2.i times in the length of the head. 

 Pectoral fin is inserted very fiir down, the lower portion of its peduncle almost on the 

 abdominal line; the fin is lanceolate, and, although mutilated, is believed to have been about 

 half as long as the head. The lateral line sweeps in a sinuous curve from a point above the 

 upper angle of the gill opening to a point somewhat in advance of the insertion of the 

 dorsal, and thence in a straight line to the base of the caudal. A line of mucous pores on 

 either side ofthe median dorsal line in advance ofthe dorsal fin.

A single specimen (No. 35634, U. S. N, M.), 4| inches in length, was taken by the Fish 

 Commission steamer Albatross at station 2222, on September 6, 1S84, in 39° 03' I'l" N. hit., 

 70O 50' 45" W. Ion., at a depth of 1,535 fathoms. 



This species is provisionally described from a careful drawing made by Jlrs. ITilde- 

 brandt, December 11, 1884, under the criticism of Dr. Beau, the type specimen being inac- 

 cessible at the time this study is made.
