 Faroe in 180 fathoms, and is recorded by Strom from 140 fathoms in Throndhjem Fjord.

Although Ribbon-fishes are spread over the whole area of the tropical and temperate 

 zones,* and must be very abundant in the abyssal fauna, nothing is known of their habits 

 and their vertical di.stril)ution. Of the oxpedition.s in which the deep-sea di-edge or trawl 

 has been used, the Challenger Expedition is the only one which obtained a single examjile, 

 and that of very small size. Large and long individuals, of course, would easily escape, 

 but one might have expected the capture of a certain number of young examples. It is 

 not improbable that such small specimens were actually caught, but destroyed during 

 the ascent of the dredge, as the fragile condition of their body can hardly be expected 

 to resist the force and pressure of the current passing through the net. Adult 

 specimens probably pass a great portion of their life on the bottom, but the not 

 uncommon occurrence of young Tvachypteri near the surface seems to indicate that 

 they live at any depth where the water ceases to be affected by the surface agitation. 



' It is notewortliy tliat no instances have been recorded of their occurrence on the western coasts of the Atlantic.
