naked parts: the preopercle, the maro-in of the jaws, parts of the snout and the whole lower surface 

 of the head. 



As to other localities the reader is referred to Oceanic Ichtlnology» p. 412. 



Trachyrhynchus Murray! Gthr. 



(Deep-Sea Fishes, Challenger Report p. 153, pi. 41, fig. A.) 



Of this .species a young one (120"") was obtained at station 73 (62" 58' Lat. N., 23' 28' Long. W., 

 Southwest of Iceland at 486 fathoms, at a temperature at the bottom of 5'.5 C). Previously it has been 

 taken in the Faroe-Channel at a depth of 555 fathoms. 



Gadoids and allied Fishes. 



Motella (Onos) Reinhardti Kr. (Tab. I\', fig. 8). 



Compare the description and figure in den norske Nordhavs Expeditions, Fiskene, S. 131, 

 pi. I\", fig. 34 and the Challenger Report p. 97, pi. XIX, fig. B. 



After this Gadoid having been sent down from Greenland several times in earlier years, it 

 was found again in the sea between Spitsbergen and Beeren-Island in the ice-cold water at a depth 

 of 658 fathoms. Later it is found again in the Faroe-Channel at a depth of 540 — 640 fathoms. Ingolf ■> 

 obtained it in a few specimens on Station 116 (70° 05' Lat. North, 8^ 26' Long. West, South of Jan ;\Iayen, 

 at 371 fathoms, brown Biloculina-mud, at a temperature at the bottom of -^ o°.4 C.) and at Station 140 

 (63° 29' Lat. North, 6 57' Long. West, North of the Faroe Islands, 780 fathoms, gray mud and a bottom 

 temperature of -^ o".9 C), also at Station 43 (West of the Faroe Islands, 61° 42' Lat. North, 10' 11' Long. 

 West, 645 fathoms, sandbottom (?), bottom temperature 0".o5 C). Some young specimens were obtained 

 at Station 2 (63° 04' Lat. North, 9^22' Long. W., 262 fathoms. Southeast of Iceland, clay and gravel, 

 temperature at the bottom 5°.3 C.) and on Station 91 (Denmark Strait, 64° 44' Lat. N., 3 1' 00' Long. W., 

 1236 fathoms, Globigerina mud, bottom temperature 3°.i C). The new localities do not much extend 

 the known geographical distribution, but seem to show, that it may occur at less considerable depths 

 and under a less cold temperature, but also at somewhat greater depths and imder low degrees 

 of warmth, a little over or under zero. A sketch executed on the Ingolf » gives it a light 

 testaceous colour. 



Of larves (on the so termed Coin-///a-sta.ge) several were fished b\- the « Ingolf* of this or other 

 arctic species, especially between the Faroe and the Shetland islands as well as east and south east 

 of these and south of Iceland, at the surface. Of the other arctic J/otella-species, M. scptcntrioiialis 

 Coll. and M. cnsis Rhdt. (compare .Norske Nordhavs Expedition p. 138, pi. IV, fig. 35—36; «Oceanic 

 Ichthyology > p. 381, fig. 327) nothing new was ascertained through the ; Ingolf » Expeditions.
