Atlantic, at the depth of 1,850 fathoms (station 106); another of 13 lines at the depth of 

 2,450 fathoms (station 348). 



LINOPHRYNE, Collett. 

 IAnophryne, Collett, Proc. Zo<">1. Soo. London, 1886, 138. — Gunthkr, Challenger Report, xxn, 57. 



" Linophryne" says Giinther, "differsfrom Melanocetus in possessing a long tentacle 

 at the throat." Collett's original description is as follows: 



Head enormous; the body slender, compressed, month oblique. Spinous dorsal 

 reduced to a single cephalic tentacle, the basal part of which is erect, not procumbent. 

 Teeth in the jaws on the vomer and the upper pharyngeals. Gill openings exceedingly 

 narrow, situated a little below the root of the pectoral. Soft dorsal and anal very short; 

 ventrals none. Abdominal cavity forming a sac, suspended from the trunk. Skiu smooth; 

 a long tentacle on the throat. 



LINOPHRYNE LUCIFER, Collett. (Figure 408.)

 xxn, 57. 



A spinous projection above each orbit. Cephalic tentacle black, with a large ovate 

 bulb, the upper half of which is white; gular tentacle much larger, terminating in two 

 ton one like appendages, which are furnished on the upper edge with a row of round, white 

 papilla-. 



Radial formula: D. 1/3; A. 2; C. 0; P. 14-15. 



Collett tells the history of its capture as follows: 



A single specimen, with a total length of 4!» millimeters, was caught by Capt. P. 

 Andresen in May, 1877, floating in the sea (about 30° N. hit., 20° W. Ion.), 3 degrees north- 

 west of Madeira, and was presented to the museum of the Christiania University. During 

 several years it remained unnoticed in the private house of the late director of the Christ i 

 ania museum, Prof. Esmark, but after his deatli it was returned to the museum (December, 

 1885). 



Mr. Andresen, who is now residing in Christiania, reports to me that on the day men- 

 tioned he was on a voyage to the West Indies. He was capturing turtle in his boat; there 

 was a heavy swell, but the water was smooth. After a time he caught sight of this little 

 black fish, which lay on the surface quite alive, but almost motionless, which was not sur- 

 prising when it was discovered that it had just swallowed a fish longer than itself. It did 

 not lie on its side, but was apparently unable to swim away. By getting the bailer under 

 it he lifted it out with ease, and in order to keep it fresh he gave, up his search for turtle 

 and rowed to the ship, where it was placed in spirits for preservation. 



CAULOPHRYNE, Goode and Bean, n. g. 



Head large, compressed. Mouth with the cleft nearly horizontal. Body short, much 

 compressed. Spinous dorsal reduced to a single cephalic tentacle, which is supported on a 

 short procumbent base. Teeth of unequal size in the intermaxillary and the mandible. 

 Vomer, palatines, and upper pharyngeals toothed. Gill openings narrow, horizontal slits 

 placed below and in front of the root of the pectorals. Branchiae in i-2-i pairs. Branchial 

 arches armed with dentigerous tubercles. Skin naked. Numerous luminous filaments on 

 head and body. Soft dorsal and anal many rayed; the rays greatly produced. Caudal 

 long, tapering. Ventrals none. Pectorals very broad, sessile, postmedian, under dorsal fin, 

 with numerous rays. Pyloric appendages reduced to one small rudiment. Air bladder 

 absent. 



CAULOPHRYNE JORDANI, Goode and Bean, n. s. (Figure 409.) 



The height of the body is nearly one-half of the total length without caudal, the greatest 

 height occurring just behind the head. The cephalic appendage has a pale tuft at its tip. 

 The length of the distal portion of the appendage equals one-third of the total length with- 

 out the caudal. The tuft is somewhat mutilated, but it shows no evidence of a laminated
