CHALINI;KA KREVIBAKBIS, (i()<.iiK and Beax, n. s. 



The length of the specimen described is 345 millimeters. It is almost entirely denuded 

 of scales; those that remain have about six longitudinal ridges comiiosed of small spines as 

 in the species of .¥(/(■;•«/•».•>■. Tlie first gill opening also is restricted as in Macrurus. The 

 teeth of the upper jaw are in a villiform l)and with the outer series enlarged. Mandibulary 

 teeth uuiserial. 



The greatest height of the body (54 millimeters) equals the length of tlie head without 

 the snout. The length of the iutermaxilla is one-third the length of the Iiead. The maxilla 

 extends to below the hind margin of the orbit. The length of the mandible is nearly one- 

 half that of the head, which is 68 millimeters long, being about one-fifth of the the total 

 length. The Ijarbel (8 millimeters) is two thirds as long as the eye and one-half as long as 

 the snout. The length of the eye (11 millimeters) is one-sixth the length of the head, and 

 one-half tlie width of the interorbital space. 



The second spine of the dorsal (42 millimeters) equals the length of the i)Ostorbital 

 part of the head. The ventral when extended reaches to the sixth ray of the anal. The 

 distance from the ventral to the vent eciuals one-half the length of the head. The length of 

 the pectoral ecpials the p()storbital part of the head. 



D. II, 8; the first 31 rays of the second dorsal occupy a space equal to the length of the 

 head. Anal: the first 25 rays occupy a space equal to the length of the head. The longest 

 anal rays are nearly half as long as the i>ectoral. 



The interspace between the first and second dorsals is one-half of the interorbital part 

 of the head. Ventral 9. Scales 8—140. 



The type of the species, Cat. Xo. 33453, U. S. X. M., was taken by the Albatross ou 

 September 4, 1883, at station 2077, in 41^ 09' 40" X. hit., G(i'= 02' 20" W. Ion., at a dei)tli of 

 1,255 fathoms. Examples were also obtained by the Albatross from station 2530, in 40^ 

 53' 40" X. lat., GGo 24' W. Ion., at a depth of 95G fathoms; Cat. Xo. 33269, IT. S. X. M., from 

 station 2037, in 38° 53' X. lat., 69^ 23' 30" W. Ion., at a depth 1,731 fathoms; Cat. Xo. 35560, 

 IT. S. X. M., from station 2210, in 39'^ 37' 45" X. hit., 71° 18' 45" AV. Ion., at a depth of 991 

 fathoms; Cat. Xo. 3339G, U. S. X. M., from station 2077, in 41° 09' 40" X. lat., 60^ 02' 20" 

 W. Ion., at a depth of 1,255 fathoms; Cat. X^o. 33272, U. S. X. M., from station 2035. in 39o 

 2G' 16" X. lat., 70° 20' 37" W. Ion., at a depth of 1,362 fathoms. 



CHALINI'RA OCCIDENTALIS, Goodi; and Bkax. 



Malacocephalus occidenlalh, Goode and Be.vn, Proc. U. S. N.at, Mus., viii, 1885, 597.— Gunther, Challenger 

 Report, XXII, 1887, 134, note. 

 A species which in general appearance and proportions resend)les Malacoccphahts 

 Uecis, Giinther. Anal fin commencing at a distance behind the vent equal to th(! length 

 of the snout, its distance from the origin of the ventrals being less than the distance from 

 the origin of the anal, which is distinctly behiml the vertical tlirougji the posterior end of 

 the first dorsal. The ventrals originate under tlie middle of tlie first dorsal, and the pec- 

 torals under its origin. The ventral extends to, or slightly beyond, the anal origin. The 

 pectoral is as long as the head without its postorbital part. The diameter of the eye is
