REPORT ON THE DEEP-SEA FISHES. 149 



narrow band iu the upper jaw, and in a single series in the lower. The two limbs 

 of the prseoperculum meet at a somewhat acute angle which is produced backwards. 



The second dorsal spine is smooth and slender ; and the second dorsal fin commences 

 at a distance Ijehind the first, which is about one-half of the length of the head. Pectoral 

 fin remarkably long, extending to the origin of the second dorsal, and equal in length to 

 the head, the snout not included. The outer ventral ray not produced. 



Scales rather thin, with from eight to ten finely crenulated radiating ridges, which do 

 not project beyond the margin of the scale. There are five scales in a transverse series 

 between the first dorsal fin and the lateral line. The head is covered with similar radiated 

 scales, which, however, are irregular as regards size and arrangement ; snout and lower 

 limb of the jirajoperculum scaly. 



Brownish-black. 



Hahitat. — 7/yaZo?2ema-ground, ofi" Inosima, Station 232 ; depth, 345 fathoms. One 

 specimen, 27^ inches long. 



A very remarkable species, which may be at once recognised by its large head and 

 long pectoral fin. The figures marked B on PI. XXIX. represent the entire fish from 

 the side, of half the natural size, and the lower side of the snout. The figure of the 

 scale is magnified four times. 



Macriirus sidcatus.

D. 10-11. p. 13. V. 7. 



Snout short, obtuse, scarcely overhanging the mouth, shorter than the eye, which is 

 contained thrice and two-thirds in the length of the head, and equal to the width of 

 the intcrorbital space. The maxillary reaches to below the middle of the orl)it. Dorsal 

 spine smooth. Vent about midway between the root of the ventrals and the anal. 

 Scales each with eight or ten spinelets irregularly placed, and less numerous in young 

 individuals, which feel bristly to the touch, separated by wide deep furrows (hence the 

 specific name). Seven scales in a sex-ies between the origin of the dorsal fin and the 

 lateral lino. Teeth in the upper jaw in two series, the outer series somewhat enlarged ; 

 mandibulary teeth unisorial. Pectoral fin about half as long as the head. Brown ; 

 lower parts of the head and abdomen blackish. 



Habitat. — Two specimens, 9 and 18 inches long, were obtained by the U.S. Fish 

 Commission in lat. 28° 30' N., long. 86° 50' W., and ofi" Martinique, at depths of 340 

 and 472 fathoms.
