The Blake obtained examples of this species from station cccxxi, in 32 c 43' 25" N. Lit., 



77 20' 30" W. Ion., at a depth of 233 fathoms; from station CCCXV, in 32 L8' 20" N. [at., 

 78° 43 W. Ion., at a depth of 225 fathoms; and from station CCCXVI, in 32° 7' K hit., 78 

 37' 30" W. Ion., at a depth of 1-'l".i fathoms. A single specimen was also obtained by the 

 Fish HawTc on October 10, 1881 (Cat. No. 12904G, TJ. S. H". M.), at station 1045, in 38° 35' N. 

 hit.. 73° 13' W. Ion., at a depth of 312 fathoms. 



L^MONEMA MKLAXl'Rl'M, Goode and Bean, u. s. (Figure 316.) 



The specimen described, catalogue number 38270, is 330 millimeters in length; it was 

 obtained by the steamer Albatross in X. hit. 30° 44'. W. Ion., 79° 20'. station 2415, in lid 

 fathoms. 



The greatest depth of the body (1G5 millimeters) is contained 45} times in the length 

 without caudal. The length of the head (68 millimeters) is slightly more than the greatest 

 height of the body. The eye is very large, its length (25 millimeters) about one-third the 

 length of the head and equal to twice the width of the interorbital space. The length of 

 the snout (18 millimeters) is about one-fourth the length of the head. The maxilla ex- 

 tends to below the middle of the eye. The length of the intermaxilla (36 millimeters) is 

 nearly one-half the length of the head. The length of the mandible (38 millimeters) is slightly 

 more than twice the length of the snout. Teeth in the intermaxilla and mandible in villi- 

 form bands. Vomerine teeth in a small circular patch on the middle of the head of the 

 bone. The barbel (17 millimeters) is about as long as the snout. The distance of the first 

 dorsal from the tip of the snout is about 4 times the length of the snout. The length of 

 the first ray of the dorsal (54 millimeters) equals that of the head without the snout: the 

 last ray is scarcely more than one-fourth as long as the first. 



The ventral consists of a single bifid ray; its distance from the tip of the snout is 

 equal to the length of the head; its length (52 millimeters) is nearly equal to that of the 

 dorsal and the pectoral when extended. It does not reach the vent by a distance equal to 

 the length of the snout. The length of the pectoral (54 millimeters) equals that of the 

 longest dorsal ray. and also equals the head without the snout. The seconddorsal is higher 

 anteriorly, anil posteriorly much higher, than it is in the middle; the longest anterior ray 

 (26 millimeters) is one half the length of the ventral, the longest posterior ray 16 

 millimeters) being one-half the length of the head. The vent is under the eighth my of 

 the second dorsal. Gill-rakers 5+15; the longest (4 millimeters) one-fourth as long as the 

 snout.
