CLASSIFIED RESUME OF ORGANISMS OBSERVED 327 



trawling nets above 3000 feet, and the largest pediculate 

 we ever caught was only about three inches long. All of 

 those seen from the bathysphere were swimming alone. In 

 half of the specimens the illicium was lighted, the glow 

 being pale lemon yellow in two specimens, and pale blue 

 in a third. One fish with unlighted illicium had luminous 

 teeth, and another had several foci of dim lights elsewhere 

 on the body. All in general resembled Melanocetus or 

 CeratiaSj rather than genera of other families. It has been 

 thought worth while to include the following list of the 

 individuals observed. 



1200 feet. One, three-inch. Very deep. Light on illicium pale 

 lemon yellow. Close to window. Repassed. 



1300 feet. One, four-inch. Luminous teeth. Very near glass. 

 Melanocetus type. 



1500 feet. One, one and one-half inches long. Lighted illicium. 



1503 feet. One, three-inch. Ceratiid type, with illicium, no 

 light visible. 



1507 feet. One, eight-inch. Mancalias- or Cry ptos paras-like. 

 No lights. In beam. 



1900 feet. One, twenty-four-inch. In general Melanocetus 

 rather than Cryptosparas type. Long, unlighted tentacle 

 visible in beam, but several foci of dim lights elsewhere 

 on body. Opened mouth and partly closed it twice before 

 it disappeared. 



2000 feet. One, twelve-inch. Very pudgy, like Melanocetus. 

 One brilliant, pale blue light on illicium. 



2470 feet. One, six-inch. Fish not very deep. Three illicia on 

 head, large one in front and two behind it close together. 

 Their light was pale, clear yellow. This fish I have de- 

 scribed as Bathyceratias trilychnus.^
