394 Mr. A. Alcock on the Bathybial Fishes 
viewed, namely : in oblique rows from above and before down- 
wards and backwards, or from below and before upwards and 
backwards; in less oblique rows converging from above and 
below to an incomplete horizontal median row; in regular 
equidistant concentric curves, of which the outer are inter- 
rupted at the edge of the scale, round a central horizontal 
row; and in a deep, close-set, diminishing series of quin- 
cunxes. There are seven and a half rows of scales between 
the base of the first dorsal fin and the lateral line. The 
interval between the dorsal fins is equal to the length of the 
postorbital portion of the head. The second dorsal spine, 
which is prolonged into a short filament, is longer than the 
head and edged in front with twenty-two semirecumbent 
barbs. The outer ventral ray is produced into a filament 
nearly as long as the fin. 
Colours in spirit :—Grey ; abdomen, throat, and paired 
fins black. 
About thirty-five very large, long, pyloric caca. Liver 
large, its right lobe occupying the whole of that side of the 
abdominal cavity. An air-bladder. 
One specimen, 11 inches long. 
Hab, Andaman Sea, 74 miles east of North Cinque Island, 
in 490 fathoms. 
Macrurus macrolophus, sp. nov. 
BG. DE. 2A 6G. (Eo 2iee Wis: 
Head conspicuously long, 34 in the total. Snout rounded, 
with a small low nasal tubercle, overhanging the mouth, 
hardly longer than the eye. Hye large, its diameter 43 in 
the head-length and considerably exceeding the width of the 
bilaterally-flattened interorbital space. Nostrils moderate- 
sized. Mouth inferior, its cleft not reaching the vertical from 
the anterior border of the orbit. Barbel less than half the 
length of the eye. A broad band of villiform teeth in each 
jaw, and in the upper an outer row of slightly enlarged teeth. 
Gill-openings rather narrow ; the gill-membranes not directly 
united, but attached on each side to the broad isthmus ; gill- 
lamine rather broad. Head and body covered with scales, 
those on the body uniformly large. A scale from the abdo- 
men has about seventeen series of semierect conical spinelets, 
arranged similarly to those of M/. brevirostris. There are five 
rows of scales between the base of the first dorsal fin and the 
lateral line. The dorsal fins are separated by an interval 
equal to the length of the postorbital portion of the head,
