i 9 4i CATALOGUE OF FISHES OF TORTUGAS 2 ^ 



Bathypterois quadrifilis Giinther 



Four specimens, 2 in fair condition, except for broken and frayed fins, are 

 included in the Tortugas collection. Two were taken south of Tortugas in 250 

 fathoms, and the other 2 are without locality labels. They are respectively 50, 55, 

 70, and 70 mm. long to the base of the caudal. 



The following enumerations and proportions are based on the specimens 

 listed: D. 12 or 13; A. 9 or 10; P. 12, 3 uppermost rays more or less separated 

 from the others, 2 uppermost ones greatly produced, reaching base of caudal; 

 V. 8, outer ray somewhat produced, reaching middle of base of anal, dilated at 

 tip; scales 48 to 56; gill rakers about 20. Head 4.6; depth about 8.5 to 10. Eye very 

 small, about 15 in head; snout 2.9 to 3.5; maxillary reaching far beyond eye, 1.7 

 to 1.8. 



Origin of anal well behind base of dorsal, and origin of dorsal nearer tip of 

 snout than base of caudal by about two-thirds length of head. Lower jaw projects 

 strongly and is curved upward at tip. 



General color of preserved specimens pale gray; each scale with a jet-black 

 spot, making crosshatching stand out prominently; base of caudal black, fins 

 otherwise largely pale. 



I find no notes on this species among Dr. Longley's field data.

Bathypterois viridensis (Roule) 



Two specimens, 75 and 144 mm. long to base of caudal, both without locality 

 data, are in the Tortugas collection. These specimens agree in nearly every 

 respect, except color, with Parr's description and figure (Bull. Bingham Oceanog. 

 Coll., vol. 3, art 3, 1928, p. 27, fig. 2). The following proportions and enumera- 

 tions are based on the Tortugas specimens: Head 3.6; depth 5.75 to 6.8. Eye 

 small, about 16 in head; snout 3.3 to 3.5; maxillary 1.55. D. 12 to 14; A. 11 or 12; 

 P. in two parts, 9 + 5, the 2 uppermost rays rudimentary, the next 2 somewhat 

 produced, reaching opposite base of dorsal; V. 7, with 1 (Parr says 2 inseparable 

 rays) greatly produced ray, reaching nearly or quite to end of middle caudal 

 rays; caudal forked, 2 lowermost rays produced, about 1.5 times as long as head; 

 scales about 53; gill rakers 26 or 27. 



Origin of anal in larger specimen scarcely in advance of end of base of dorsal; 

 in smaller specimen, nearly under middle of dorsal. 



General color of larger specimen very pale; head largely black; a broad black 

 bar just behind base of dorsal and another at base of caudal. The smaller speci- 

 men is rather darker in color, and the black head and bars are less distinct. 



Deep water on both sides of the Atlantic. S. F. H. 



Chlorophthalmus chalybeius (Goode) 



Common south of Tortugas between 180 and 280 fathoms, as many as 72 

 specimens having been taken in a single haul. 

 Eleven specimens, 47 to 130 mm. long to base of caudal, are included in the
