differs, however, from both through the low situation of the lower SAO. and by 
the larger number of AO., (10) 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. warmingi was described from a specimen caught in the Atlantic 
32° 6' N. lat., 39 0 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 + i, 33 ° C. 17th of June 
1902. 52 0 39' S. lat. 37 0 35' W. long. 
Numerous specimens from a depth of 2,500 m. 23 June 1902. 48° 27' S. lat. 
42° 36' W. 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.

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

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 3 7 /fi° in length of head. Diameter of eye con- 
tained about 5V3 times in length of head. Snout decidedly longer than eye con- 
tained 3 7 /io times in length of head. No vomerine teeth, a few on the palatine. 
ii 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 instances a loosened tooth is still hanging in the soft tissues although the new tooth is
