32G DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



reaching nearly to the vent. Its length (l.") millimeters) nearly ('((nal to height of body. 

 Distance from origin of ventral to vent slightly greater than height of body. 



Color, light yellow, with silvery reflections, with clouding of brown above lateral line 

 and numerous black chromatophores ; a series of irregular brown blotches above the 

 lateral line, with one or two, nnuh darker, extending up on the diu'sal tin. In many speci- 

 mens the color is uniform yellow, with simply the dark ocellaj showing. 



The type (Gat. No. 37340, U. S. N. M.) was obtained by the Albatross, Irom station 

 2402, in 280 36' N. lat., 850 33/ w. long., at a depth of HI fathoms. The ChoUeiKjer took it 

 from station 122, off Pernambuco, Brazil, in 350 fathoms. 



NEOBYTHITES MARGINATUS, Goode and Bean (Figure 2110.) 



Neobyihites marginaiiiiij Goode and Bean, Bull. Miis. Cniiip. Zool., xii, 1G2. 



Body compressed, somewhat elongate; its height (18 millimeters) contained 5^ times in 

 its total length, and less than the length of the head. Interorbital area convex, its width 

 (5i millimeters) greater than the diameter of the circular eye, which is 4J millimeters. 

 The length of the head (22 millimeters) is contained 4g times in that of the body. IMouth 

 large, the maxilla extending considerably behind vertical through posterior margin of 

 oibit; its length equals half that of the head. The length of the mandible (13 millimeters) 

 is slightly more than two-thirds of height of body. 



The teeth as in K. gillii. 



Gill-rakers slightly longer than half the diameter of the eye, 7 and 3 rudiments below 

 the angle of the anterior arch. Pseudobranchiiie absent. A long, flat si)ine upon the 

 upper edge of the oiierculum, extending back nearly to its margin. Two short, flat spines 

 upon the angle of the preoperculuni. JSostrils as in N. gillii. 



The scales small, very closely imbricated, in about 123 rows, 7 above and 29 below the 

 lateral line. 



The lateral line obsolete in its jjosterior half. 



The dorsal is composed of 101 rays; its distance n-om the snout is contained 4 times in 

 total length. 



The anal originates under the fourteenth dorsal ray at a distance from the snout con- 

 tained more than 2g times in the total length. 



The caudal consists of about 8 or 9 rays very closely placed; its length is contained 

 about lOJ times in the total length. 



The pectoral is placed much as in Benthocomctes, itn length about equal to 2;^ times that 

 of the head, extending to vertical through the vent. 



The ventral, a bifid ray inserted in advance of base of pectoral, n<it reaching to the 

 vent; its length (14 millimeters) considerably less than the height of body. The distance 

 from its origin to the vent (19 millimeters) slightly more than the height of the body. 



(5olor light yellowish brown, an obscure narrow band of darker brown commencing on 

 the snout, interrupted by the eye, and extending backward two-thirds of the distance to the 

 tail ; another beginning on the snout, extending over the eye and back as far as the first de- 

 scribed, interrupted posteriorly. Dorsal fin milky white at base in its anterior third; above 

 this a Ijlackish band extending the whole length of the fin. A narrow white margin above. 



The type is from the Blake station Lxxix, off Barbadoes, 209 fathoms. 



Neohythites macroj)s, Giinther [Challenger Eeport, xxvi, 102, PI. 10, Fig. A] is similar 

 in proi:iortions and general api)earance, and is l)lotched in color, though in a different jiat 

 tern. It is from Challenger station 173, off INIatukee, Fiji Islands, at a depth of 310 

 fathoms, and from the Investigator, in Andaman Sea, in 205 to 271 fathoms. 



In 1891 twenty specimens were taken in the Andaman Sea, Inrr.stigator stati<m, 11.5, 

 188 to 220 fathoms. Their length varies from 4 to 8J inches. [Alcock, oj). cit., 1891
