of dorsal; pectoral fin with narrow base, very long, extending nearly to 

 root of ventral. Scales of lateral line larger than others, more or less 

 hidden in a pouch of black skin, with a phosphorescent organ at base of 

 free portion ; these large scales continued for some length on the tail 

 and cover base of anal fin, which, like the dorsal, is covered in its basal 

 half with small scales; head naked; upper portions of gill cov^er and 

 cheek covered with scales similar to those of body. Band of premax- 

 illary teeth broader than maxillary band ; palatine teeth in two separate 

 patches, each being of an oval shape, with the pointed end directed for- 

 ward ; pterygoid teeth in a very narrow band, which extends far back-' 

 ward in cavity of mouth ; basibranchials with a long and broad band. 

 Four well-developed gills. Outer branchial arch with 14 widely-set gill 

 rakers, of which the middle ones are slender and as long as eye, the others 

 becoming shorter toward end of series. Uniform black. Common in 

 the central parts of the Atlantic ; first discovered by the Challenger oft" 

 the Strait of Gibraltar, Station V, depth 1,090 fiithoms, one specimen, 

 21i inches long ; near Marion Island, Station 146, depth 1,375 fathoms, 

 four specimens, 18 to 20 inches long. Specimens also obtained by the 

 Blake, at Station cccviii, at a depth of 1,242 fathoms, and Station 

 cccxxv, at a depth of 647 fathoms, {^juaxpog, long ; x^'Pj hand.)

B. 12; D. I-IO, 11; V. I, 8. Snout moderately produced, its preoral 

 portion forming f of its own length ; eye small, equal to about 5 of post- 

 ocular portion of head, and measuring a little less than + of width of 

 interorbital space. Head longer than distance between it and root of 

 ventral. Maxillary reaching vertical of front margin of eye. Dorsal 

 entirely behind ventrals ; anal commencing as far behind root of ventrals 

 as the latter are behind the preoperculum ; pectorals nearly reach back- 

 ward to the ventrals. Squamation similar to that of A. macrochir. The 

 type of this description was obtained by the Albatross at Station 2037, at 

 a depth of 1,731 fathoms. Others were obtained from Stations 2051, 1,106 

 fathoms; 2035, 1,362 fathoms; 2052, 1,098 fathoms. (Goode & Bean.)

 Ichthyology, from which our accounts of the deep-sea fishes are largely 

 derived.)
