394 Mr. A. Alcock on the Baihyhial 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 J 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 cajca. 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, 7^ miles east of North Cinque Island, 

 in 490 fathoms. 



Macrurus macrolophusj sp. no v. 



B. 6. D. 11. A. 66. P. 21. V. 8. 



Head conspicuously long, 34 in the total. Snout rounded, 

 with a small low nasal tubercle, overhanging the mouth, 

 hardly longer than the eye. Eye large, its diameter 4^ 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- 

 laminaBi 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.
