nets at 1800 feet, but large specimens are exceedingly rare, 

 and caught much deeper. 



Family idiacanthidae 



Black Idiacanthiis females, from five to eight inches in 

 length, were recognized four times, between 800 and 

 1503 feet. Three of the identifications were very accurate, 

 as I had been studying the genus and the fish was in my 

 mind, so that I was subconsciously prepared for instant 

 analysis. The remaining report, however, is questionable, 

 for females have a most degenerate cheek light, and the 

 light I saw seemed much too large. Two eight-inch fish 

 were seen together, the others singly. Fully pigmented fe- 

 males have not been taken in our trawling nets above 3000 

 feet. 



At 1900 feet, when we were both looking out of the 

 window, Mr. Barton saw the first living Sfylophthalmus 

 ever seen by man, a sight which completely eluded me, 

 although it must have been within a foot of the windows. 



Family gonostomidae 



Cyclothones are by far the most numerous deep-sea fish 

 in this area, and many were seen on every dive from 400 

 feet downward. During the first few dives I confused these 

 small fish with worms, but once I had recognized them, I 

 had little diflficulty in distinguishing between the two
