foot in length. Most of the large larvae which we capture 

 in our trawhng nets are of the slender, Nemichthyid type 

 and are taken below 2400 feet. Yet from the bathysphere 

 I recognized this form at 1500 feet. Much higher than this 

 I saw large, very deep leptocephalids, of which we have 

 captured only one specimen off Bermuda. 



The iridescent silvery eye led almost always to the dis- 

 covery of a leptocephalus. I would then look in the path 

 of the eye movement, and the body would appear. Several 

 times black markings were clearly observed. There was 

 never any trace of luminescence. Usually the larvse vi- 

 brated swiftly along, unaffected by the beam. Twice, very 

 large leptocephalids swam by in pairs. 



Order iniomi 

 Family myctophidae 



Myctophids have been recorded about thirty times, but 

 they were probably seen on many other occasions and not 

 recognized. They ranged in depth between 400 and 2900 

 feet, and in length up to six inches. A dozen times they 

 were seen singly; the remainder swam in schools, often 

 forming loose groups only, consisting of from several to 

 fifty or sixty individuals. The larger numbers moved to- 

 gether, all facing, or all turning at once. The lateral lights 

 were sometimes dim, sometimes bright, but without excep- 

 tion seemed to glow steadily. Their tint was usually pale 

 yellow, but several times a reddish tinge was observed. 

 Their course was occasionally deflected by the beam; some-
