closely in Other external characters we feel eoinpelled to retain it in that genus for the pres- 

 ent at least. 



A specimen (D. 77; A.. 61; 7.6; L. lat. 10) was taken by the Albatross from station 

 I'll 7. in 33° 18' 30" N. lat.. 77 i>7' W. Ion., off Cape Fear, at a depth <>t' 95 fathoms. 



CITHARICHTHYS SPILOPTERUS, GCntuer. (Fignre370.) 



Oitharichtkya spHopterut, GOnther, Cat. Fish. Brit. Mus., iv, 421. 



The height of the body is two-fifths of the total length (without caudal), the length of 

 i In' head two-sevenths. Seales of the lateral line subquadr angular; lateral line nearly 

 straight, gently descending anteriorly. Snout with the .jaws equal in front, rather longer 

 than the eye, the diameter of which is one-sixth of the Length of the head. The maxilla i \ . 

 the length of which is contained twice and two-thirds in that of the head, extends beyond 

 the middle of the orbit. Anterior teeth in the upper jaw widely set, much larger than the 

 posterior, which are close together and very small; the lower jaw with seven or eight dis 



taut teeth of i lerate size on each side. Eyes separated by a very narrow scaleless ridge, 



their front margins being nearly on the same level. Fin rays scaly. The dorsal commences 

 a little before the upper eye. and terminates close by the caudal; its longest rays are be- 

 hind the middle, and one-half of the length of the head. Anal spine none. Caudal rounded; 

 its length is one sixth of the total. The pectoral is rather longer than half the length of 

 the head; ventral much shorter, extending beyond the origin of the anal. Gill rakers 

 lanceolate, pointed, one-third as long as the eye. 



Radial formula: D. 7(i-7S; A. liO-03; L. lat. 47-50. 



Color, grayish olive (in spirits); a series ol distant blackish spots along the basal 

 portions of the anal and dorsal tins. 



The species has been taken on the Atlantic coast of tropical America and on the west 

 coast of Africa. A single specimen was taken by the Blake from station ccxliv, in 23° 13' 

 X. hit., 89° 10' W. Ion., at a depth of si fathoms.

Greatest height of the body (lb millimeters) is contained 2.3 times in the total length, 

 and equals about 4 times the. least height of the tail. 



Scales thin, deciduous, cycloid, large, 48 in the lateral line, which is slightly curved 

 over the pectoral; 14 above and lb below the lateral line. 



The length of the head (27 millimeters) is contained 3J times in the total length, and 

 ecpials about 3J times the diameter of the eye (8 millimeters). The iuterorbital space is very 

 narrow, its width less than one-fifth diameter of eye; ridge rather prominent, narrow, sharp. 



The upper eye distant from profile by a space (2 millimeters) about one fourth of the 

 orbital diameter. 



The length of the maxillary (12 millimeters) is less than half the length of the head ; that 

 of the mandible (10 millimeters) more than half, and twice the diameter of the eye. 



The teeth uniserial in both jaws, those in the front much the largest. A strong spine 

 upon the snout overhanging the upper lip (much lower than in ('. unicornis). Above this 

 there is a second, shorter spine. 



The dorsal tin begins upon the snout in advance of eye upon blind side. It is composed 

 of 91 rays, the longest somewhat behind the middle of the tin; its height (13 millimeters), 

 about equal to half the length of the head. 



The anal fin originates about under the origin of the pectoral; its distance from the 

 snout (3b millimeters) equals one third of the total length. It is composed of 73 rays, and 

 is as high as the dorsal. 



Caudal subsessile, pointed, its length (17 millimeters) contained about 5* times in total 

 length, and equaling twice the diameter of the orbit.
