460 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



depth of 324 fatlioiiis, as a collateral type. The Blalce also obtained 13 specimens from 

 station xxvir, oil" St. Vincent, at a depth of 94 fathoms, and the Fhh Hatch captured a 

 single specimen from station 1154, in 39° 55' 31" N. lat., 70° 39' W. Ion., at a depth of 193 

 fathoms. 



APIIORISTIA PIGRA, Gooi>K and Bean. (Figure 377.) 



Aphtristia p'ujra, GooDK and Bean, Hull. Mus. Conip. Zool., Cambridge, xii, 154. 



It is distinguished by its abbreviated form, and its large, rough, strongly pectinate scales. 

 The extreme length of the type is OS millimeters. 



The body is shorter tlian in the congeneric Atlantic species; its greatest height is con- 

 tained 3^ times iu its total length, or three times in total without snout. 



The scales are large, very rough, with strong horizontal striai and strongly denticulated 

 margins, and rather loosely fixed to the skin; about 0.3 in a horizontal series, 34 in a trans- 

 verse series. The jaws and S7U)ut are covered with small scales. The length of the head 

 is contained 4J in total length. The length of the snout is contained 4i times iu that of 

 the head. The eyes are moderate in size, very close together, with no scales between; the 

 upper is very slightly in advance, and is distant from the dorsal outline a space equal to 

 its own short diameter. The greatest diameter of the eye is contained six times in the 

 length of the head. The mouth is oblique, curved, its posterior angle directly beneath the 

 middle of the lower eye. Length of gape in that of head four times. The teeth are feeble, 

 closely placed, a little stronger on the coh)red side. 



The nostril tubular, a little nearer to the lower eye than to the tip of the snout. 



The dorsal fin begins at a point over the middle of the upper eye, and contains about 90 

 rays to the middle of the base of the caudal. The rays about the middle of the fin are the 

 longest, their height being a little more than ^ that of the body. The distance of the anal 

 fin from the snout is contained 3'| times in total length. The longest anal rays are al)out 

 the middle of the body; their length is equal to that of the longest in the dorsal. The 

 anal is connate with the caudal, and consists of 69-75 rays. 



The length of the median caudal rays is contained nearly seven times in the total 

 length. The distance of the ventral from the snout is contained 4| times in the totiil length. 

 It is separated from the anal by a distance equal to the long diameter of the eye. The num- 

 ber of ventral rays is four; the longest ray is 3i times as long as head. 



Color grayisli or brownish, with a submetallic lustre upon the scales when examined 

 separately. The denticulations of the scales are dark and prominent, giving a clouded 

 general aspect. Some of the siinxller specimens (from station 231S) have a few large irreg- 

 ular l)rownish blotches above and a dark subcircnlar blotch near the root of the tail, its 

 diameter twice that of the eye. Colorless below. 



Radial formula: D. 90; A. 09-75; V. 4; P. none. L. lat. 65. 



The species is described from a specimen obtained by the Blalce from station XXIIT, oif 

 St. Kitt's, West Indies, at a depth of 250 fathoms ; with specimens obtained by th& Albatross 

 from station 2318, in 24° 25' 45" N. lat., 81° 40' 45" W. Ion., at a depth of 45 fathoms, and 

 from station 2405, in 2S'2 45' K lat., 85° 02' W. Ion., at a depth of 30 fathoms as collateral 

 types. The Albatross also secured examples from station 2425, in 36° 20' 24" N. lat., 74° 

 46' 3" W. Ion., at a depth of 110 fathoms; and from station 2374, in 29° 11' 30" N. lat., 

 85° 29' W. Ion., at a depth of 20 fathoms. 



APHORISTIA DIOMEDEANA, Goode and Bean. (Figure 378.) 



AjihiiriKlia dinmrdeaiia, Godhk and J!eax, Proc. U. S. Nat. Mus., viii, 1885,589. 



Scales moderate, somewhat loosely fixed, pectinated; about 85 in a longitudinal, 35 in 

 a transver.se, series. Jaws and snout covered with small thin scales. 



Length of head contained 5j- times in tlie standard hmgth. Length of snout 5 times in 

 that of head. Eyes moderate, equal, very close together, without intervening scales; the 

 upper eye is directhj above the lower one, and is distant from the dorsal outline an interval 

 equal to its own least diameter; diameter of eye in length of head 6 times.
