280 PAPERS FROM TORTUGAS LABORATORY vol. xxxiv 



on belly. Two faint dark brown streaks, of width of pupil, on side from upper 

 margin of gill opening and from behind pectoral, fading into the general ground 

 color on the tail." No trace of dark streaks remains in the preserved specimens, 

 the color being uniformly grayish or yellowish, variable among specimens; only 

 the margins of the dorsal and anal are dark posteriorly. 



The foregoing rather long description is offered because the literature seems 

 to contain only the original, based on a specimen 112 mm. long. The species 

 apparently was previously reported only from deep water off Brazil. S. F. H. 



Neobythites gillii Goode and Bean 



The collection contains a single specimen, 85 mm. long. Dr. Longley listed 

 only 1 specimen in his field data, taken in 55 fathoms, which probably is the 

 one at hand. 



Head and body compressed, the tail tapering gradually; eye moderate, longer 

 than the round, projecting snout; mouth large, slightly oblique; maxillary 

 reaching well beyond eye; upper posterior angle of opercle with a sharp spine, 

 preopercle with a few hidden points; head and body covered with small scales, 

 not embedded on sides. Vertical fins confluent; caudal well exserted; dorsal 

 origin a little behind vertical from base of pectoral; pectorals not quite reaching 

 opposite vent; ventrals inserted on isthmus, each composed of 2 filaments, failing 

 to reach vent by diameter of eye. 



The following enumerations and proportions are based on the specimen in 

 hand: Head 4.2; depth 5.0; snout to origin of dorsal 3.8; snout to vent 2.5. Eye in 

 head 3.75; snout 6.4; maxillary 2.1; pectoral 1.8; longest ventral filament 1.4. 

 D. about 97; A. about 80; scales about 105, between upper angle of gill opening 

 and origin of dorsal 28; gill rakers 10. 



Dr. Longley described the color as silvery on sides and back with two large 

 black spots and with rings. That description holds for the preserved specimen, 

 though it may be added that the back is brownish, with darker brown markings, 

 some of which at least form partial rings, and that in addition to the two black 

 spots mentioned there is a third small one at and on the base of the dorsal pos- 

 teriorly. The snout, lower surface of head, chest, and bases of ventrals and pec- 

 torals bear black punctulations.

Barathronus bicolor Goode and Bean 



A single specimen, 120 mm. long, bearing tin tag number 62, is included in 

 the collection. Though the key to this tag number has not been found, numbers 

 60 and 61 are flatfishes, taken south of Tortugas in 168 fathoms. Number 63, a 

 specimen of lizard fish, is either from the same haul or from another one in 295 

 to 315 fathoms. There can be little doubt that the specimen of Barathronus 

 bicolor is from one of the two hauls mentioned. 



The following proportions and enumerations are based on the specimen at 

 hand: Head 5.3; depth 6.6; distance from tip of snout to origin of dorsal 2.2. Eye
