DISCUSSION OF SPECIES AND THEIK DISTRIBUTION. 413' 



Radial lurinula: D. ii, 9, 113; A. 118; V. '20; V. 9; B. VI. 



The type specimeu, 458 milliineters in length, was taken by the Blake from station 

 occvili, iu 41'5 L>5' -1.5" ]Sr lat., OrjO sry 30" W. Ion., at a depth of 1,242 fathoms. The BInl-e 

 also secured specimens, apparently belon<;in<;- to this si^ecics, from station cccxvii, in 

 31° 57' jST. lat., 78° 18' 35" W. Ion., at a depth of 333 fivthoms; and from station cccxxv, in 

 33035' 20" ISr.lat., 760 W. Ion., at a depth of G47 fathoms. 



The AlhatrosH obtained examples from station 2095, iu 39° 29' N.lat., 70° 58' 40" W. Ion., 

 at a depth of 1,342 fathoms; from station 2105, in 37° 50' N. lat., 73° 03' W. Ion., at a depth 

 of 1,.395 fathoms; and Cat. Xo. 332S0, U. S. N. M., from station 2037, in 38o 53' N. lat., 

 G90 23' 30" W. lou., at a depth of 1,731 fathoms. 



CIIALINURA BREVIBAEBIS, Goode and Bean, n. s. 



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

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

 in the species of il/'((THrHS. The first gill opening also is restricted as iu Marrurus. The 

 teeth of the upper jaw are in a villiform baud with the outer series enlarged. Mandibulary 

 teeth uniserial. 



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

 the snout. The length of the iutermaxilla is one-third the length of the head. 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 barbel (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 the width of the interorbital space. 



The second spine of the dorsal (42 millimeters) eqixals tlie length of the postorbital 

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

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

 the pectoral equals the postorbital 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 pectoral. 



The interspace between the first and second dorsals is one-half of the interorbital i)art 

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



The type of the species, Cat. No. 33453, TJ. S. N. M., was taken by the Albatross on 

 September 4, 1883, at station 2077, in 41"^ 09' 40" N. lat., 66° 02' 20" W. Ion., at a depth of 

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

 53' 40" K". lat, 660 24' W. Ion., at a depth of 956 fathoms; Cat. No. 33269, U. S. N. M., from 

 station 2037, iu 38^ 53' N. lat., 69^ 23' 30" W. h)ii., at a depth 1,731 fathoms; Cat. No. 35560, 

 U. S. N. M., from station 2210, in 39^ 37' 45" N. lat., 71° 18' 45" W. Ion., at a depth of 991 

 fathoms; Cat. No. 33396, U. S. N. M., from station 2077, iu 41° 09' 40" N. lat., 60° 02' 20" 

 W. Ion., at a depth of 1,255 fathoms; Cat. No. 33272, U. S. N. M., from station 2035, in 39° 

 26' 16" N. lat., 70'^ 20' 37" W. Ion., at a depth of 1,362 fathoms. 



CHALINURA OCCIDENTALIS, Goode and Beax. 



Malacocephalue occidentalU, Goode and Bean, Proc. U. S. Nat. Mus., viii, 1885, 597. — Guntheu, Challenger 

 Report, XXII, 1887, 134, note. 



A species which iu general appearan(-c and proportions resembles Malacoceplialus 

 Icevis, Giinther. Anal fin commencing at a distance behind the vent equal to the 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 behind the vertical through the posterior end of 

 the first dorsal. The ventrals originate under the middle of the 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 i)art. The diameter of the eye is
