322 CLASSIFIED RESUME OF ORGANISMS OBSERVED 



times the fish swam right into it, and frequently turned 

 and came close up to the glass. Except in the following 

 cases the genera and species could not be identified with 

 any certainty: 



MyctopljiiTn coccoi: This species was recognized twice 

 at 750 feet (a single one and seven together) , once at 800 

 feet (eleven individuals) , and once at 2060 feet (four M. 

 coccoi in company with a single Lampanyctus) . The ven- 

 tral flash was seen twice, pale blue. Recognition was pos- 

 sible because of the characteristic pattern of their photo- 

 phores, and the narrowness of the caudal peduncle. The 

 uppermost trawling record for this species off Bermuda is 

 1800 feet. 



Lampanyctus sp. This genus was recognized once, at 

 2060 feet. A single individual was swimming with four 

 M. coccoi. It was identified by means of its luminous scales. 



Diaphtts ssp. Members of this genus were recognized 

 once at 800 feet (three individuals, each three inches long) , 

 twice at 1500 feet (a school of about twenty individuals, 

 and one single one) , and once, questionably, at 1533 feet. 

 The headlights were always large and brilliant. 



Lampadena sp. At 2900 feet several five-inch members 

 of this genus swam past so slowly that their luminous cau- 

 dal plates and photophore patterns were very distinct. It is 

 possible that they were Lampadena minima. 



No Myctophid has been taken in our trawling nets above 

 1800 feet, but the majority of bathysphere records of this 

 group were made at higher levels.
