6o EINAR LÖNNBERG, (Schwed. Südpolar-Exp. 



ger", in the Bay of Bengal by the "Investigator" and in the Pacific off the coast 

 of Colombia and Ecuador by the "Albatross", has a smaller number of scales in a 

 lateral series 18—20, a larger head ("Is of total length), smaller eyes, and origin of 

 dorsal midway between snout and root of caudal, etc. M. maxillaris Garman 

 (III, 10), found off the coast of Ecuador, has a much wider mouth, origin of dorsal 

 behind the middle of the body, etc. Other species of the genus have a larger num- 

 ber of dorsal rays and are thus still more easily distinguished from this one. 



The genus Mclanipha'es (including Plectromiis) appears to be a cosmopolitan 

 genus in the oceanic abysses, and probably many species of the same remain to 

 discover. 



2. Myctophum antarcticum (Gthr). 



Numerous specimens collected floating on the surface. 7th of Febr. iço2. 

 64° 14' S. lat. 52' 50' W. long. 



I specimen taken in an open net, sunk to a depth of 2,800 m. 4th of Febr. 

 1902. 63' 24' S. lat. 45' 40' W. long. 



I specimen taken in the same way as the above mentioned specimen. Depth 

 2,700 m. 27th of June 1902. 49' 56' S. lat. 49° 56' \V. long. 



About one of the last specimens is written on the label: "brownish black, fins 

 hyaline, luminous organs, iris and opercle bright silvery". The specimens collected 

 floating on the surface are in the best state of preservation and still show the 

 characteristics mentioned. They are also large measuring in average between 8 and 

 9 cm. without the caudal. This species was first discovered by the "Challenger"-' 

 e.xpedition in the Antarctic Ocean where two specimens were captured at the sta- 

 tions 156 and 157. The depth there was resp. 1,975 and 1,950 fathoms, but GÜN- 

 THER assumes that the specimens entered the dredge whilst it was hauled up. 



Under the name of Scopeliis collctti LCtken " described a small specimen which 

 according to Brauer belonged to this species. This one was kept in the Zool. 

 Museum of Kristiania and labelled as having been caught in the Pacific "about 

 600 miles West from Cape Horn". The authors of "Oceanic Ichthyology" referred 

 5. colletti of LCtken to their new genus Bent/ioseiiia, but had no new specimens 

 to record. The "Challenger "-specimens described by GÜNTHER under the name 

 of 5. aniarcticus they seemed inclined to refer to the genus Rhinoscopelus (1. c. 

 p. 512). Finally BRAUERN stated the identity.
