Jordan and Evermmtn. — Fishes of Nortli America. 2601 



pectorals, very long, reaching past vent, which is at second third of length, 

 including caudal; dorsal almost as high as body, without plume in front. 

 A^ertebriB 36 + 18. Shining leaden gray, a silvery hand produced by the 

 vertebral column showing through. Cuba. (Poey); not seen by us. 

 {rpaxvc,, rough; oupd, tail.) 

 Trachypterus trachyurus, Poey, Memorias, n, 420, 1861, Cuba. 



Family CCXVIII. STYLEPHORID^. 



Body elongate, compressed, ribbon-shaped; the dorsal extending from 

 head nearly to end of tail; tail terminating in an exceedingly long, cord- 

 like appendage, about twice as long as head. Anal absent; ventrals 

 absent; caudal erected upward, having its rays connected by a rather 

 Arm membrane. Snout produced; mouth small, toothless; maxillary 

 bones small, short, hidden behind premaxillaries ; mandible long, extend- 

 ing far behind the eye. Eye large, turned forward; suborbital very large, 

 covering nearly the whole of cheek and extending backward behind eye. 

 Opercles small. Gill openings wide; gills 4. Vent premedian. Branchi- 

 ostegals 4. (Goode & Beau.) This family is based on a single specimen 

 obtained in the West Indies in 1790 and preserved in the British Museum. 

 The relations of the fish are uncertain, and it may not belong to the Tteni- 

 osomi. Its nearest relations are, however, apparently with Trachyterus.

2974. STTLEPHOBCS CHORDATUS, Shaw. 



Head&; depths. D. 110; C.6; P. 13; B. 4. Snout produced, subcyliu- 

 drical; mouth small and toothless; maxillary bones small, short, and hid- 

 den behind the intermaxillaries; mandible long, extending far behind eye; 

 eyes large, close together, directed forward toward snout; suborbital very 

 large, covering nearly the whole of cheek, and extending backward behind 

 eye ; opercles small ; gill openings very wide ; gills 4. Vent situated before 

 middle of total length; pectorals pointed, directed upward, about | as 

 long as head ; dorsal extending from head nearly to end of tail ; caudal 

 directed upward, and having its rays connected by a rather firm mem- 

 brane, the tail terminating in a narrow baud-like appendage about twice 

 as long as body. Color uniform silvery. (Giinther.) This remarkable 

 form is known only from a single specimen, 11 inches long, with the 

 caudal appendage 22 inches in length, which was taken in the Atlantic, 

 between Cuba and Martinique, about the year 1790, and is now in the 

 British Museum. It is undoubtedly an inhabitant of great depths.
