markings show that it is not the greatest depths that it inhabits. Alcock 

 suggests that the mouth of his Atcleofus*) indiens might be adapted for 

 suction. I can support this opinion neither in the case of Ijimaia with 

 its subterminal mouth, nor in that of A teleopus, the soft, quite unprotected, 

 overlapping snout of which would certainly offer great inconvenience 

 to sucking. — The toothless mouth of only a moderate width and the weak 

 jaws are not adapted for catching or holding quickly moving prey, the 

 maxillaries protractile in a downward direction show that the fish is a 

 ground feeder and not addicted to the habit of standing head down in a 

 nearly vertical direction (" gründein " in German) as many other fishes do, 

 but reposes leisurely on the ground when taking food. Further, the short 

 ventral rays reminding one of the ventral fins of certain Blennies and of the 

 pectorial " feelers " of the Triglids and Ereunias, and the posteriorly 

 directed vent point to a ground dwelling life : apparently we have here to 

 do with a mud-sipper. 



In the character of its tissues and of its colors this fish much resembles 

 another animal, of the habits of which nothing is as yet known I 

 am speaking of the Cephalopod Alloposus. There too we have a similar 

 colorless and gelatinous tissue covered over by a thin layer of the same 

 peculiar semitransparent brownish color. I think it not improbable, that 

 they both belong to the same bathymetrical zone, viz. 500-1000 fathoms. 



I have named this species after another explorer of the Sagami-Sea, 

 Dr. Fr .nz Doflein, of the University of Munich, who led me to the 

 study of marine life, as a token of my thankfulness. 



*) Most certainly the Indian species ought to be generically separated from Atekopus 

 jafonietu on account of its gill-membranes being united to the isthmus.
