326 DKEP-SKA nSTIKS OF THE ATLANTIC BASIN. 



leacliinp: nearly to tlie voiit. Its hiiijitli (15 millimeters) nearly ctinal to lieijjlit of l)0(ly. 

 Distance from oripn ol' ventral to vent slightly greater than height of body. 



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

 and nnmcrons l)lack chromatopliores; a series of irregular In'own bloteh(>s above tin- 

 hiteral line, with one or two, much darker, extending up on the dorsal fin. In many speci- 

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



The type (Cat. No. 373-10, TT. S. N. M.) was obtained by the Alhnfrnss, from station 

 2402, in 28o 36' N. lat., Sr.o 33' W. long., at a depth of 111 fathoms. The ChaHetifjtr took it 

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



NEOBYTHITES MARGINATUS, Goode and Bean, (Figure ;i90.) 



Neohylhiles marginntits, Goode and Bean, Bull. Mils. Comji. Zoo]., xii, 102. 



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 

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

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

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

 orbit; 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 i\". gillii. 



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

 the angle of the anterior arch. Pseudobranchiai absent. A long, flat spine upon the 

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

 upon the angle of the preoperculnm. Nostrils as in N. fiillii. 



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

 lateral line. 



The lateral line obsolete in its iiosterior half. 



The dorsal is comi)osed of 101 rays; its distance irom 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 2§ times in the total h-ngth. 



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

 about 10| times in the total length. 



The pectoral is placed much as in Bcnthocomefes, its length about e(|ual 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, not 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. 



Color 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 l)ack as far as tlie first de- 

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

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



The type is from the Blalce station lxxix, oft' Barbadoes, 209 fathoms. 



JS'cohythlteH macropx, Giinther [Challenger lieport, xxvi, 102, PI. 10, Fig. A] is similar 

 in proportions and general appearance, and is blotched in color, though in a difterent pat 

 tern. It is from ChnUcngcr station 173, ofl" Matukee, Fiji Lslands, at a depth of 310 

 fathoms, and from the T» rest i gator, in Andaman Sea, in 2(i5 to 271 fathoms. 



In 1891 twenty spi'cimens were taken hi the Andaman Sea, Investigator station, 115, 

 188 to 220 fixthoms. Their length varies from 4 to 8J inches. [Alcock, op. cit., 1891
