Bd. V: 6) THE FISHES OF THE SWEDISH SOUTH POLAR EXPEDITION 65 



differs, however, from both through the low situation of the lower SAO. and by 

 the larger number of AO., (lO) 9 + 7, while the same series counts in the former 

 of the two others 5 — 6 + (6 — 7) and in the latter (5 — 6) + 5. M. braueri has 

 also a greater number of anal rays viz. about 18 compared with resp. 13 — 14 and 

 13 in the others. M. maderense has also a frontal horn on either side, directed 

 forward from the upper rim of the orbit. The name of this species indicates where 

 it was first found, but LüTKEN has also recorded it from the Westman Islands, 

 celand. M. tvariiiingi was described from a specimen caught in the Atlantic 

 32° 6' N. lat., 39" 28' W. long. 



7. Cyclothone microdon (GÜNTHER). 



I specimen in a net drawn from a depth of 2,000 m. to the surface, the actual 

 depth being 2,622 m. and the temperature at the bottom + 1,33° C. 17th of June 

 1902. 52° 39' S. lat. 37 35' W. long. 



Numerous specimens from a depth of 2,500 m. 23 June 1902. 48° 27' S. lat. 

 42° 36' \V. long. 



Numerous specimens from a depth of 2,700 m. 27th June 1902. 49° 56' S. lat. 

 49 56' W. long. 



This fish seems to be a cosmopolitan as already the ''Challenger" expedition 

 collected it at the most various localities. 



8. Astronectes antarcticus n. sp. 



I specimen from a depth of 2,500 m. 23 June 1902. 48' 27' S. lat. 42° 36' 

 W. long, 



P. 9. V. 7. D. II. A. 15. 



Length of the head contained about 5 times in total length without caudal, and 

 a little larger than greatest depth of body. Least depth of caudal peduncle con- 

 tained 3V3 in greatest depth and 37/10 in length of head. Diameter of eye con- 

 tained about 5^,3 times in length of head. Snout decidedly longer than eye con- 

 tained yjio times in length of head. No vomerine teeth, a few on the palatine. 

 1 1 teeth * in the upper jaw, the second largest of the same size as the foremost 

 mandibular fang. Pectorals not reaching half way to ventrals, and ventrals reaching 



* In some instnnces a loosened tooth is still hanging in the soft tissues although the new tooth is 

 already fully developed.
