Type.~Cat. No. 72952, U.S.X.M., 8.4 cm. in length, taken with a 

 beam trawl at station 5607 (lat. 0°04'00''S.; long. 121° 36' 00'' E.), 

 near Binang Unang Island, Gulf of Tomini, Celebes, at a depth of 761 

 fathoms, on a bottom of fine sand. 



In this extraordinary fish the head is nearly as long as the remainder 

 of the body, and the length of the mouth is more than half that of the 

 head. It would appear that the cayernous, elastic mouth is a trap 

 into which the food is lured and dispatched. The light from the liulb 

 in the roof of the moutli sliines through the tootldess space in the 

 front of the upper jaw and attracts the prey which, having entered 

 the mouth, is prevented from escaping and brought within reach of 

 the lateral teeth by the two pair of large hinged, hooked teeth. 



ipagidostomus; from 7:ay:r, a trap or snare, and aro/ia, a mouth.)
